RENEW’s new blog Employee Profile series highlights our employees who make us great. This month we interviewed our talented and personable engineer leading our decarbonization projects in New York City, Charlie Tryon.

Q: How long have you worked for RENEW Energy Partners?

A: I have been with RENEW since September 2022.

Q: What sort of work do you do for the company?

A: As a Project Engineer with RENEW my primary role is to oversee the continuous operation of RENEW’s assets and to oversee/monitor all aspects of projects being implemented ranging from design to construction and start up. I also lend technical assistance to the Business Development team when needed during project vetting.

Q: Where are you from? What is one aspect that you enjoyed about the place that you grew up?

A: I am from New York’s Capital Region; Albany, which was really an incredible place to grow up. Situated about 3 hours from both Boston and New York respectively made it very easy to go to sporting events, concerts, museums, and sightseeing. The Capital Region also offers the Adirondack Mountains, Lake George, and Saratoga Springs within an hour drive so there is always plenty to do and see.

 Q: What activities/hobbies do you enjoy in your daily life? How do you relax?

A: My favorite hobbies are golf, art, and music. In the summer I golf as much as possible on the weekends, in the winter months I like to paint and draw, acrylics, pen, and inks mostly. Music is throughout the year; I love going to shows/concerts or playing the drums at home.

Q: Why is sustainability/decarbonization important to you? How did you get started in this career/field?

A: I first began really paying attention to the environment over 13 years ago while working in a wastewater treatment plant. I started as a laborer, eventually becoming a licensed New York State treatment plant operator and during my tenure there I became increasingly interested in the treatment process.

Removing contaminants and treating waste streams is a process that is constantly monitored and measured, showing just how much of an impact is being made in protecting natural waterways. For the past 10 years in the construction sector, sustainability and decarbonization have been a way to carry that same notion.

The work we do is typically either improving existing building performance or developing and building new construction that carefully considers minimizing the impact we have on the environment; in both scenarios we can measure the exact impact the project has made, which is incredibly gratifying.

Q: What sustainability practices have you seen that have surprised and/or excited you?

A: I was very surprised to see increased use of geothermal in New York City. Living in such a dense city I had not expected to see geothermal implemented as we have seen over the past couple of years. I typically get most excited about seeing on site power generation work logistically.

Q: Why do you choose to work with RENEW?

A: RENEW has been an incredible opportunity for me to work with a highly talented team that is unabashedly mission oriented. For me, it does not get any better than being able to work on sustainability and decarbonization projects that I am overtly passionate about with this group.

Q: What are you most excited about for the future of the energy industry?

A: I am most excited to see decarbonization work increasingly embraced by major cities and communities. In NYC we have seen various regulatory agencies and departments become much more familiar and interested in the technologies, equipment, and implementation process. It is very positive to see entities actively learning and taking a general interest in moving these projects forward. With this type of support and enthusiasm I think the positive changes we can make to the energy industry are enormous.

A Master Service Agreement: the key to decarbonization for energy saving retrofits

Master Service Agreement: The Key to Decarbonization

A Master Service Agreement: the key to decarbonization for energy saving retrofits

RENEW Energy Partners specializes in funding energy saving retrofits for your commercial, industrial, and institutional buildings. A Master Service Agreement is the key to decarbonization as it allows us to provide and support various technologies to make your buildings more efficient and cut down on your energy costs.

How can a Master Service Agreement be the “key to decarbonization”?

A decarbonized energy system will become a mandatory step for businesses looking to reduce climate emissions and energy transition risks. However, achieving decarbonization goals requires putting a budget in place to fund the plan. A recent Deloitte survey shows that CFOs prefer certain funding options over others.

For finance chiefs, there are three primary strategies for funding their decarbonization goals:

  1. Reassigning growth capital from carbon-heavy resources
  2. Using operational cashflow savings
  3. Applying for grants

Most CFOs view decarbonization as “costly undertaking rather than in investment.” However, “future-focused” organizations have their lead financial executives involved in the decarbonization strategy and identify innovative strategies to fund their decarbonization programs.

To help address this challenge, RENEW offers our Master Service Agreement (MSA) as an energy finance solution. This two-part contract is the key to decarbonization for future focused organizations and CFOs to implement their decarb strategies in a way that is an investment and not a costly undertaking.

Structure of a Master Service Agreement

The MSA includes a General Terms & Conditions section to cover the legal aspects of the agreement between the customer and RENEW while also defining specific Project Addendums to scale energy efficiency and sustainability initiatives. With the MSA Project Addendums, RENEW can implement client-defined scopes of work for energy efficiency retrofits such as lighting, HVAC, and smart energy controls; as well as Power Purchase Agreements (PPA) to install on-site clean power including microgrids, solar energy, energy storage, geothermal and combined heat and power.

These scopes of work may include a share of savings provision that defines the measurement and verification of the project, along with maintenance requirements over the agreement period.

RENEW’s Master Service Agreement is the key to decarbonization as it is more flexible and modular than traditional funding. We share early project development risk by signing a Memorandum of Understanding (MOU) that allows RENEW and its design partners to fully develop the project scope without any upfront capital required.

Once the MOU work is complete, we deliver definitive contracts for the MSA and project addendums. Additional Project Addendums can be added at any time, giving our clients the ability to easily work with RENEW on any future decarbonization projects but does not obligate them to work solely with RENEW on sustainability.

Top benefits of the MSA vs regular decarbonization funding:

  • Upgrades are funded with future long term savings.
  • We provide up-front funding to purchase, install, and maintain the new systems.
  • Each month after installation, for the duration of the agreement, we share a portion of the savings with the client.
  • The client can take ownership of the new systems at the end of the agreement with 100% of the savings going to their company’s bottom line.

How this high-tech manufacturer uses RENEW’s Master Service Agreement:

MACOM Technology Solutions, a high-performance microwave and optical semiconductor manufacturer, recently worked alongside RENEW and an independent consultant to design, implement and fund a microgrid solution for their Lowell, Massachusetts corporate headquarters. RENEW now owns and maintains the microgrid under a 15-year PPA, saving MACOM hundreds of thousands of dollars per year on their energy bills while reducing over 1860 metric tons per year and adding significant resiliency to MACOM’s manufacturing facility.

Renew Energy Partners provides turnkey solutions for funding, installing, and managing energy efficiency and on-site clean power generation projects. We help building owners reduce their carbon footprint and save money while making their buildings cleaner, nicer, and more resilient. With RENEW’s energy-as-a-service model, energy saving retrofits and power upgrades are funded by future savings and are at no cost to the building owner.

Energy Saving Retrofits: Building Envelope and Insulation

Exposed beams showing building insulation.

RENEW Energy Partners specializes in funding energy saving retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we can install to make your buildings more efficient and reduce your energy bill. One strategy for significant savings is to upgrade your building envelope and insulation to prevent energy from escaping and being wasted.

Building Envelopment and Insulation

Decarbonizing retrofits typically involve multiple aspects of a building’s systems, such as HVAC, lighting, and water usage. However, the building’s envelope and insulation are often the first place to start, as it can have a significant impact on a building’s energy use and GHG emissions. Upgrading HVAC and other mechanical upgrades are certainly important, but if you have a drafty building, even the most efficient heating and cooling systems will not be effective.

Insulation:

Insulation has to do with preventing heat flow through building perimeters. A building envelope keeps conditioned air inside the building. Together, they help keep buildings cool in warmer months and warm in cooler months.

Additionally, piping that carries hot water, steam, or chilled water to heating and cooling appliances needs to be insulated, and over time that insulation can break down and need replacement.  Uninsulated hot water or steam pipes will lose heat constantly, leading to poor efficiency.  Uninsulated chilled water piping has the same problem but can also cause condensation and lead to property damage.

When considering insulation options for decarbonizing retrofits, it’s important to consider the R-value, or thermal resistance, of the material. The higher the R-value, or the more heat resistant the insulation material, the better the insulation will perform.

Insulation plays a major role in the energy efficiency of a building. It can help keep the indoor temperature stable, reducing the need for heating and cooling systems. When selecting insulation materials for a retrofit project, there are several factors to consider, including budget, effectiveness, and environmental impact. Some common insulation materials include fiberglass, cellulose, and spray foam, but not all insulation materials are created equal.

Spray foam for example, is not always the best product. Its main advantage is that industrial applications are fast to apply in new build construction, so it’s generally cheaper. A more common retrofit technique is a siding replacement project, foam board (polystyrene) is added to the outside surface of a building, followed by a layer of “house wrap” vapor barrier, then new siding. Generally, you remove the existing siding first, but that depends on the existing construction method.

Building Envelopment:

The building envelope itself is made up of the walls, roof, windows, doors, and other exterior components of a building. It serves as a barrier between the interior and exterior of the building, protecting the occupants from the elements and providing thermal insulation. When a building is properly insulated and sealed, it can significantly reduce energy consumption and GHG emissions.

In addition to insulation, other aspects of the building envelope that can contribute to decarbonizing retrofits include windows and doors, roofing, and air sealing. Upgrading to high-performance windows and doors can also reduce heat transfer, while reflective roofing can minimize the amount of heat absorbed by a building. Proper air sealing can also help to prevent drafts and minimize energy loss.

Lastly, there are building management technologies on the market that focus on monitoring building envelope. Once installed, any air leaks can be detected easily and in real time, strengthening the building envelope and reducing maintenance costs.

Conclusion

Building Envelope and Insulation are often referred to in the energy industry as a building’s “lungs.” If there are holes in the lungs, then any air that is pumped into them has the possibility of leaking out. Any energy saving retrofits applied to HVAC systems will have minimal effect if a building is not well enveloped and insulated.

Updating a building’s envelope and insulation can help customers keep their buildings airtight, keeping the energy they produce within their walls for as long as possible. This helps maintain consistent internal environments and avoids excess energy output to continuously heat and cool indoor spaces.

No matter how you decide to increase your energy efficiency and decrease your carbon footprint, these kinds of projects require funding. In order to fund an energy efficiency project for your building(s), RENEW Energy Partners offers an energy service agreement (ESA). The Energy Service Agreement:

  • May be treated as an off-balance sheet transaction. In that case, you do not own the asset or carry it on your balance sheet (consult your tax advisor).
  • RENEW provides preventive and corrective maintenance in the service agreement.
  • Your payment to RENEW will be based on the energy savings confirmed once the system is operational. 

The RENEW Energy Service Agreement allows businesses to focus on what they do best, while ensuring that their facilities are performing at their peak with brand new, and high-efficiency equipment. In this current climate of cost control and resource allocation, the energy service agreement is the perfect solution to help businesses meet sustainability goals and keep facilities in top condition.

Water Saving Retrofits

Water Saving Retrofits

Water Saving Retrofits

RENEW Energy partners specializes in helping fund energy saving retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we can install to make your buildings more efficient and reduce your energy bill. One place to deliver significant savings is by reducing your water consumption with a water saving retrofit.  

Water Saving Retrofits

Water savings are a very beneficial by-product of energy saving projects, but not always the initial driver of a new project. Typically, when we talk about saving water, we are really talking about saving the energy required to pump, purify, and/or heat water. In an energy saving retrofit, you want to eliminate places where you’re wasting water for the same reason’s you want to improve efficiency of any energy systems–to reduce the energy usage. Except for fixing a large leak, water saving retrofits are always going to be grouped together with controls or another efficiency improvement in order to decarbonize most effectively.

The Basics

Opportunities for water savings can be found in three places: plumbing fixtures, irrigation, and HVAC equipment.

As with any retrofit it is important to meter your consumption before planning a project. Water submeters can help break down your building’s usage in more detail than your utility bills, and in complex systems submeters can help identify sources of waste that would otherwise go unnoticed.

Water efficiency is one of the easiest and most measurable energy saving retrofits because it typically involves one-to-one fixture or appliance replacements.

It is important to remember that while simple upgrades are simple to implement, more complicated upgrades require knowledge of the water codes in your building’s jurisdiction.

Plumbing

Common plumbing retrofits include low-flow urinals and toilets, which can provide significant water savings. Both urinals and toilet upgrades will require the upfront cost of flush valve and china replacement. Additional modifications to the piping in the plumbing chase or below the flow may be required as well.

To provide low-flow lavatory and shower upgrades, it is important to review all water distribution systems. Oversized pipes and the location of the fixture compared to the heating source can increase the amount of energy your system needs to heat water. Adjusting the locations of these features and sizing piping diameter correctly can reduce that energy spend. Additionally, ensuring that hot water recirculation loops are sufficiently insulated is a critical part of reducing domestic water costs.

Irrigation

If irrigation is your biggest energy spend, upgrading controls should be a priority. Irrigation controls can help you monitor consumption in real time, as well as more accurately deliver water where it’s needed.  Delivering the right amount of water at the right time is the key to efficient irrigation.

HVAC

You can learn more about the history, basics, and future of HVAC retrofits in our previous blog posts here.

Besides decreasing carbon fuel usage, major water reductions are often a great side effect of upgrading an outdated heating system. In particular, transitioning away from steam heating can yield both huge water and energy savings.  If eliminating steam is not an option, upgrading and replacing steam traps or condensate return systems can still have major impacts in a large system.

Additional Water Conservation Methods

Beyond the basics, retrofits can include more specialized technology such as dishwasher and garbage disposal replacement for buildings that have kitchens and food waste. More efficient closed loop dishwashers can use significantly less water and energy than older steam driven ones, providing plenty of energy savings.

Water controls are also a crucial element in sustainability projects. Smart water meters deliver consumption and temperature data in real time in order to educate building owners and provide the opportunity for long-term behavioral changes. Smart leak detection technology, as well as humidity detectors, can easily detect leaks that need to be addressed in a retrofit. In addition, they send out alerts as soon as a new leak happens, thus preventing more damage from occurring and minimizing maintenance costs. Water control technologies can deliver significant savings for customers and new products are continuing to be developed and introduced to the market.

Other campus water improvements can include leak monitoring as well as replacing any grass lawns with drought-tolerant or native landscaping.

Conclusion

By pairing water savings with a larger energy saving retrofit, you can simultaneously decarbonize and reduce your energy bills. When paired with buildings controls, clients can monitor their water use and identify maintenance issues in real time.

Reducing your buildings water demand will also benefit your greater community by reducing demand on communal water infrastructure.

No matter how you decide to improve your water system, energy savings retrofits projects require funding. In order to fund an energy saving retrofit for your building(s), RENEW Energy Partners offers our own energy service agreement (ESA). The Energy Service Agreement:

  • Can be treated as an off-balance sheet transaction. You do not own the asset or carry it on your balance sheet. (You will consult with your accountant on this).
  • RENEW provides preventive and corrective maintenance in the service agreement.
  • Your payment to RENEW will be based on the energy savings confirmed once the system is operational.

Unlike a lease or a loan, which are on balance sheet, do not include maintenance, and may or may not deliver energy savings, the service agreement provides all of the above and then some:

  • Executing a service agreement is fast – once the project is scoped by an energy professional (and we can recommend one), you execute a simple service agreement contract and RENEW will fund the project.
  • Executing a service agreement frees up your capital budget for your other priorities, allowing you to focus on growing your core business.
  • Executing a service agreement now means your net cash flows are higher than waiting and doing it yourself in a year.
  • And finally – executing a service agreement means flexibility. Perhaps you buy another building or look at additional efficiency measures–with a one-page addendum to your existing ESA you can have those new lights, HVAC, plumbing, and controls at your new building, and you simultaneously reduce your operating expense! 

The RENEW Energy Service Agreement allows businesses to focus on what they do best, while ensuring that their facilities are performing at their peak with brand new, and high-efficiency equipment. In this current climate of cost control and resource allocation, the energy service agreement is the perfect solution to help businesses meet sustainability goals and keep facilities in top condition.

Employee Profile: Carter Kupchella

RENEW’s newest employee profile blog series features our employees who make us great. This month we interviewed one of our talented Project Engineers, Carter Kupchella.

Q: How long have you worked for RENEW Energy Partners?

A: I started with RENEW in December 2022.

Q: What sort of work do you do for the company?

A: I work as a Project Engineer, so I support all our projects with my technical background.  I wear a lot of hats, from helping analyze the potential of projects in development, to supporting our EPC contractors through construction and operation of equipment.

Q: Where are you from? What is one aspect that you enjoyed about the place that you grew up?

A: I grew up on the south shore of Massachusetts, in Scituate.  I will always love the ocean, and small coastal fishing towns.  I grew up learning to sail, spending summer days at the beach, and eating fried clams and lobster – I wouldn’t trade it for anything.

 Q: What activities/hobbies do you enjoy in your daily life? How do you relax?

A: I love anything that gets me outside. In the winter that’s usually skiing, and in the summer, I’ll go hiking, mountain biking, or out onto the nearest body of water.  I’m also a car nut, and while I don’t have anything to wrench on right now, you can usually catch me researching or browsing eBay for a project.  In 2023 I am relocating from Boston to Utah, and I can’t wait to spend even more time outside doing those things I love.

Q: Have you ever worked in another field? What was it and why?

A: I spent a year after college working in construction management for a nonprofit, building housing in a disaster recovery zone. I wanted to build something physical and make a concrete positive impact on the world.  I would say I did that, as we built more than 50 homes in that year, and I made a lot of personal connections with the people and families we were able to assist.

Q: What is one fun fact about you?

A: I’m getting married in September 2023, but because of our move out west (which we didn’t have planned when we got engaged) it will be a “destination” wedding for us– to Massachusetts!

Q: Why is sustainability/decarbonization important to you? How did you get started in this career/field?

A: I knew from when I was in college that I wanted to make an impact on the energy economy, but it took some exploring before I found the niche where I could be useful.  I worked for a design-build engineering firm for 5 years that specialized in energy reduction and decarbonization projects, and that experience helped me see just how huge the issues we face as a society are.  It also helped me learn how to approach projects within operating institutions and businesses, and how implementation is never as simple as having the most efficient design.

Q: What sustainability practices have you seen that have surprised and/or excited you?

A: I get excited about optimized energy systems and eliminating waste.  In the past, the projects I’ve worked on that excite me the most involve using “waste” heat for a novel application – like using the heat removed from a chiller to reheat ventilation air, or combined heat and power projects.  However, what’s surprised me is that even if you have a really optimized design or idea, it’s typically a financial or administrative factor that can hold up a great project.

Q: Why do you choose to work with RENEW?

A: Being a part of RENEW allows me to be close to major carbon and energy reduction projects and truly measure my impact.  I’m also happy to be around people every day who share that feeling of accomplishment associated with helping to save the environment.

Q: What are you most excited about for the future of the energy industry?

A: I’m excited because I feel that progress really is possible and happening around us.  The financial incentives are finally aligning with the moral necessity of addressing climate change, and the number of people in this space just continues to grow.  It’s an exciting time to be here!

HVAC Retrofits

The Future of HVAC Retrofits

HVAC Retrofits

RENEW Energy Partners specializes in funding energy efficiency retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we can install to make your buildings more efficient and reduce your energy bill. One strategy for significant savings is to upgrade to your commercial HVAC systems to heat and cool your building more efficiently.

The Future of HVAC Retrofits

For our last two blog posts we have talked about HVAC, its history, current technology, and its important role in energy efficiency retrofits. But beyond the basics, there is newer technology that promises to be the future of HVAC retrofits. This technology shift is often referred to as electrification.

HVAC Electrification:

Electrification, or converting your heating from fossil fuel burning systems to electric, is a common and effective energy efficiency retrofit that will further decarbonize your building and could eliminate your gas, oil, or steam utility bills. Just like the rapid advancement of electric vehicles, there is no point of use emissions. Your buildings environmental impact is now tied to the local utility grid carbon intensity. Combining full building electrification and either on-site or off-site renewables allows buildings to be carbon net-zero.

The two most common HVAC retrofit projects include heat pump and electric boiler installations. Heat pumps in particular are a revolutionary invention because they can address both heating and cooling, sometimes simultaneously, and are always more energy efficient than burning a fossil fuel on site.

What are Heat Pumps?

In simple terms, a heat pump moves heat from a cold place to a warm place. They are powered by electricity and transfer heat using compressors and a refrigerant. In cooler months, this can mean pulling heat from the cold outdoor air and transferring it indoors.  In warmer months, they can pull heat out of indoor air to condition a space. In colder climates, a secondary electric heat source can be added for additional or backup capacity. Heat pumps do not burn fossil fuel like an oil or gas furnace does, making them more environmentally friendly. Additionally, because they move heat instead of generating it, heat pumps will only consume between 20% and 50% of the energy input that a boiler or furnace (even an electric one) would need to provide the same amount of heat.

There are a few different types:

  • Air Source Heat Pumps: Air source heat pumps absorb heat directly from the air. They are not as effective in cold weather, as there is a minimum air temperature at which they can operate (depending on the refrigerant used). Air source heat pumps generally work best in mild climates or during the “shoulder season” – temperatures between 5 and 25 degrees Celsius (between 41 and 77 degrees Fahrenheit), though some can operate below freezing at a reduced capacity.
  • Ground Source Heat Pumps: These heat pumps absorb heat from the ground. In cold weather, ground source heat pumps are more effective than air source heat pumps, because the ground retains heat through the winter. In most cases, the ground temperature will stay above 5 degrees Celsius (41 degrees Fahrenheit) allowing for year-round operation. This can also be called a geothermal heat pump.
  • Water Source Heat Pumps: In addition to pulling heat directly from the air and ground, heat can be conducted via water from almost any other heat source. Water can contain more heat than air can (think about a cast iron pan cooling in the air vs being doused with cool water), which is why many buildings already distribute heat with water. By integrating with the existing building infrastructure, these heat pumps can make use of energy that may currently be going to waste, such as the heat rejected from refrigeration or a data center. In this case, the name can be confusing because “water source” is misleading – the water is the medium but not the ultimate “source” like air or ground are for the other examples above. A water source heat pump is a general term for a heat pump that uses any other heat source as an input, conducted to it via water piping. There are also true “water source” heat pumps that can pull heat from a lake or river, but they’re uncommon. Four-pipe heat pumps can heat and cool, but not simultaneously. Six-pipe heat pumps (and some specialized “heat recovery style” four-pipe systems) can heat and cool at the same time, which is ideal for buildings that require heated office space as well as significant amounts of freezer storage. Read more about water saving retrofits here.

What are the Electric Boiler Options?

  • Electric Boilers: Electric heaters are powered by electricity, whether from the electric grid or stored in batteries. Typically, electric boilers can transfer 100% of their provided electrical energy into heat, though there are slight losses in the electric and heat distributions. They are safe, energy efficient and affordable. Cons include that they are affected by power outages.
  • Electric Infrared Heaters: An infrared heater is typically more efficient than a standard electric boiler, as there are fewer losses in distribution. 100% of the energy produced can be kept in the conditioned space. An infrared heater also has more power options. They can be powered by electricity, but also by propane and natural gas (which would bring up the carbon footprint and is not recommended for an energy efficiency retrofit).

Conclusion

To summarize, when contemplating an energy efficiency retrofit project, implementing HVAC retrofits to your systems is a crucial way to decarbonize and save money. While you can update more traditional fossil-fuel-powered heating and cooling modules to be more energy efficient, the most progressive update you can make is to electrify your HVAC. This will lower your bills, decarbonize your building, and will benefit the health of all employees. It will also clearly position you and your company as a leader in carbon reduction.

No matter how you decide to increase your energy efficiency and decrease your carbon footprint, these kinds of project require funding. In order to fund an energy efficiency project for your building(s), RENEW Energy Partners offers an energy service agreement (ESA). The Energy Service Agreement:

  • Can be treated as an off-balance sheet transaction. You do not own the asset or carry it on your balance sheet. (Renew does not provide accounting advice. Our customers consult their own accounting teams on accounting treatment).
  • RENEW provides preventive and corrective maintenance in the service agreement.
  • Your payment to RENEW will be based on the energy savings confirmed once the system is operational.

Unlike a lease or a loan, which are on balance sheet, do not include maintenance, and may or may not deliver energy savings, the service agreement provides all of the above and then some:

  • Executing a service agreement is fast – once the project is scoped by an energy professional (and we can recommend one), you execute a simple service agreement contract and RENEW will fund the project.
  • Executing a service agreement frees up your capital budget for your other priorities, allowing you to focus on growing your core business.
  • Executing a service agreement now means your net cash flows are higher than waiting and doing it yourself in a year.
  • And finally – executing a service agreement means flexibility. Perhaps you buy another building or look at additional efficiency measures–with a one-page addendum to your existing ESA you can have those new lights, HVAC, and controls at your new building, and you simultaneously reduce your operating expense!

The RENEW Energy Service Agreement allows businesses to focus on what they do best, while ensuring that their facilities are performing at their peak with brand new, and high-efficiency equipment. In this current climate of cost control and resource allocation, the energy service agreement is the perfect solution to help businesses meet sustainability goals and keep facilities in top condition.

Employee Profile: Michael Savage

RENEW’s new Employee Profile blog series will be highlighting our employees that make us great. This month we interviewed our Director of Business Development, Michael Savage. 

Q: How long have you worked for RENEW Energy Partners? Why do you choose to work with RENEW?

A: I have been lucky enough to have worked at RENEW for 5 years now. Before RENEW I was working for a New England based solar development company focusing on commercial and industrial solar PV projects. In that time solar was heavily incentivized by the Federal Government and by the States, some of my projects would be 100% paid by incentives even if the project didn’t produce clean energy. However, all those customers still needed the upfront capital to get the project started, after a few years of having amazing opportunities fall short because of financing, I was excited about the prospect of working with RENEW to solve this capital challenge.

Q: What sort of work do you do for the company?

A: I am a project developer and lead our project development team. RENEW’s third party funding of energy assets makes this work very interesting, as one day we may be building a proposal for a large battery storage system and another we may be working with a corporate sustainability team to uncover sustainable solutions across their portfolio.

Q: Where are you from? What is one aspect that you enjoyed about the place that you grew up?

A: I grew up near Smugglers Notch Vermont. What is probably a tourist destination for many, was a wonderful home to me. One thing that I enjoyed, was just being outside, there was always something to do every season.

Q: What activities/hobbies do you enjoy in your daily life? How do you relax?

A: My hobbies right now are quite limited as my wife and I welcomed twins two years ago. I am looking forward to teaching them how to ski next winter. I also love old cars. I have a 78 F-150 and I am an avid Celtics and Patriots fan.

Q: Why is sustainability/decarbonization important to you? How did you get started in this career/field?

A: My passion for sustainability and decarbonization goes to back to my love for winter sports. Growing up in Vermont, from November to April we would be either up on the mountains or snowmobiling the trails. As the winter seasons became shorter, I was being taught about climate change in school and from there on out I became focused on doing something about it. I went to University of Rhode Island to study the environmental and natural resource economics. I received an energy fellowship there and interned for the Rhode Island of Office of Energy and Rhode Island Renewable Energy Fund. I haven’t looked back since.

Q: What sustainability practices have you seen that have surprised and/or excited you?

A: I have been surprised by the municipal level regulations around carbon emissions. New York City’s Local Law 97 was released in 2019 and caries a hefty fine if the building owners do not decarbonize. Then to see cities like Boston copy that law almost verbatim gives me hope that we can transition to a cleaner future.

Q: What are you most excited about for the future of the energy industry?

A: Electric cars are pretty awesome. I am looking forward to getting one or converting my old truck.

HVAC Energy Efficiency Retrofits: The Basics

hvac energy efficiency retrofits

RENEW Energy partners specializes in helping fund your energy saving retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we can install to make your buildings more efficient and reduce your energy bill. One place to deliver significant savings is by heating and cooling your building more efficiently, with energy efficiency retrofits to your Heating, Ventilation, and Air Conditioning “HVAC.”

Last month we discussed the history of HVAC, a story where Willis Carrier’s practical solution to too much humidity in a publishing factory led to the first mass-produced Cooling and Ventilation System. Today, HVAC systems continue to get more efficient, regulating climates throughout modern buildings.

HVAC Retrofits

For energy efficiency retrofits, the first places you need to look are the upgrades that will save you the most money. You should aim for an HVAC system that is at least 80% efficient. If your HVAC is not as efficient, updating your system will reduce your energy bills. When updating your HVAC, you need to think about the following:

Basic Energy Efficiency Retrofits

    • Economizers:
      • An economizer is a part of the outdoor system, most often mounted on the roof, of an HVAC system for commercial buildings. The economizer evaluates outside air temperature and even humidity levels. When the exterior air levels are appropriate, it uses the outside air to cool your building. HVAC economizers use logic controllers and sensors to get an accurate read on outside air quality. As the economizer detects the right level of outside air to bring in, it utilizes internal dampers to control the amount of air that gets pulled in, recirculated and exhausted from your building. It saves on energy, helps your A/C last longer, and improves air quality.
    • Compressor/Condenser
      • The compressor reduces the volume of gas to add pressure to it. The compressor uses more power than any other component of an air conditioner, cutting down on how much power it uses helps immensely with increasing energy efficiency. Upgraded compressors provide the ability to operate at a lower capacity with controls that include Variable Frequency Drives.
      • An HVAC condenser takes the pressurized gas and turns it into liquid vapor.
      • Condensers and compressors should be upgraded at the same time to create the most efficient system possible.
    • Condensate Recovery
      • In a typical commercial air conditioning system, warm, humid air from the building is run over a cold air handler that cools the air. When this is done, condensate water is created and recovered for reuse. A drip pan collects this relatively clean water, and it is discharged to a sewer.
      • With condensate recovery, that water is diverted to the cooling system, helping the system run more efficiently.
    • Duct Insulation/Duct Sealing
      • To prevent air leaks, duct sealing is necessary along the entire length of the ductwork system. Air leaks in your ductwork system can account for a significant loss of energy and money, especially larger systems in commercial buildings. The most insulated method of construction continues to be pioneered by the Passive House International construction standard.
    • Duct Size Optimization
      • Oversized Ducts: Larger than normal ducts are certainly capable of handling more airflow. But your HVAC system may not be equipped to pump that much air. In fact, your system needs a specific air pressure in the ductwork to properly distribute air. Oversized ducts could cause your HVAC system to work too hard and limit the amount of conditioned air that reaches your home. Forcing your system to work harder than it should leaves it prone to breakdowns and increases your energy usage.
      • Undersized Ducts: If your ducts are too small to accommodate the air flowing through them, the pressure increases and backs up in the system. This causes resistance for the blower fan, reducing your HVAC system’s efficiency and longevity. Over time, this can lead to significant stress on the components and can inevitably lead to a breakdown.
      • Duct Sizing Method: The Manual D Sizing Method is the industry standard that was developed by the Air Conditioning Contractors of America. This method involves evaluating the individual rooms in your home to determine optimal airflow, control excessive noise, seal ductwork, provide insulation, and retrofit the design as needed. This all works to correct pressure imbalances and ensure your system runs as efficiently as possible to supply each room of your home with adequate, conditioned airflow.
    • Variable Air Volume (VAV)
      • Variable air volume (VAV) systems enable energy-efficient HVAC system distribution by optimizing the amount and temperature of distributed air. Appropriate operations and maintenance (O&M) of VAV systems is necessary to optimize system performance and achieve high efficiency.
    • Heating and Cooling Recovery
      • This is the process of recovering excess thermal energy that would otherwise be emitted, in order to use it as energy and reduce your overall consumption.
      • Thermal energy can be recovered from water, air, or a ground source.
      • This can also fall under the umbrella of CHP (Combined Heat and Power), which could further reduce energy usage.

Chiller Upgrades.

For energy efficiency retrofits, it is important to specifically think about how your building is cooled. Freezer storage alone makes up about one percent of global emissions. Here are a few things to think about:

      • Chillers can be regulated by air or water. Air chillers are less expensive but use more energy.
      • Water chillers must be efficient and up to date to conserve and reuse water, but when maintained, are much more energy efficient.
    • Chiller Controls
      • The most efficient ones we can install include Variable Frequency Drives (VFDs) that regulate the amount of energy needed throughout the day depending on internal and external temperatures.
    • Modular Chillers
      • Modular chillers are ideal because each module can operate independently from each other. If one module fails, the other can continue to run. This is ideal for efficiency and maintenance.
    • Heat Recovery Chillers
      • If heating and cooling are needed at once, heat recovery chillers can allow for the heat they emit to be redirected to other energy sources. These chillers don’t always get hot enough for cold climates but are ideal for mixed use spaces.

Conclusion

To summarize, when contemplating energy efficiency retrofits, updating your HVAC systems is a crucial way to decarbonize and save money. Additional savings can be made by implementing water saving retrofits. The most ideal systems interact with each other and redirect excess energy for further use. An energy management system and variable frequency drives can help you control and monitor your HVAC effectively so that it does not have to run at full capacity 24 hours a day.

Finally, keep your buildings and pipes well-insulated to prevent energy leakage.

No matter how you decide to increase your energy efficiency and decrease your carbon footprint, these kinds of project require funding. In order to fund an energy efficiency project for your building(s), RENEW Energy Partners offers an energy service agreement (ESA). The Energy Service Agreement:

  • Is an off-balance sheet transaction. You do not own the asset or carry it on your balance sheet.
  • RENEW provides preventive and corrective maintenance in the service agreement.
  • Your payment to RENEW will be based on the energy savings confirmed once the system is operational.

Unlike a lease or a loan, which are on balance sheet, do not include maintenance, and may or may not deliver energy savings, the service agreement provides all of the above and then some:

  • Executing a service agreement is fast – once the project is scoped by an energy professional (and we can recommend one), you execute a simple service agreement contract and RENEW will fund the project.
  • Executing a service agreement frees up your capital budget for your other priorities, allowing you to focus on growing your core business.
  • Executing a service agreement now means your net cash flows are higher than waiting and doing it yourself in a year.
  • And finally – executing a service agreement means flexibility. Perhaps you buy another building or look at additional efficiency measures–with a one-page addendum to your existing ESA you can have those new lights, HVAC, and controls at your new building, and you simultaneously reduce your operating expense!

The RENEW Energy Service Agreement allows businesses to focus on what they do best, while ensuring that their facilities are performing at their peak with brand new, and high-efficiency equipment. In this current climate of cost control and resource allocation, the energy service agreement is the perfect solution to help businesses meet sustainability goals and keep facilities in top condition.

A Brief History of HVAC: An Important Energy Saving Retrofit

RENEW Energy partners specializes in helping fund your energy saving retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we can install to make your buildings more efficient and reduce your energy bill. One place to deliver significant savings is by heating and cooling your building more efficiently, with upgrades to your Heating, Ventilation, and Air Conditioning “HVAC”.

A Brief History of HVAC (Heating, Ventilation, and Air Conditioning):

In terms of heating, Benjamin Franklin invented the cast iron Franklin stove in 1742, which was a predecessor of the furnace. Until 1885, most homes were heated by wood-burning fireplaces, but a riveted-steel coal furnace transported heat by natural convection via ducts from the basement furnace to upper rooms. Cast iron radiators were invented around the same time and enabled homeowners to heat their homes with a coal-fired boiler that could deliver hot water or steam heat to radiators in every room. In 1935, the first forced-air furnace was introduced and used an electric fan to distribute coal-heated air through the home’s ducts; gas and oil-fired versions followed.

Where cooling is concerned, Willis Carrier is generally credited with the invention of Air Conditioning in 1902, motivated to solve a humidity problem for a Brooklyn publishing company. He designed and patented his “Apparatus for Treating Air” that used cooling coils to either humidify the air by heating water or dehumidify by cooling water using an additionally patented control system. When he realized other businesses could benefit from temperature and humidity regulation he formed his own company, the Carrier Engineering Corporation.

Carrier’s company installed the first well-designed cooling system for theaters in Los Angeles in 1922. Air was pumped through higher vents, which resulted in more equally distributed cooling. On Memorial Day in 1925, Carrier introduced a centrifugal chilling system at New York’s Rivoli Theater: a breakthrough in HVAC inventions. Although it was more reliable and less costly than previous cooling systems, it was still too big and expensive to use wide scale.

Frigidaire and General Electric both appeared on the HVAC scene within a decade of Carrier’s big achievement. In 1929, Frigidaire debuted a split-system room cooler that was shaped like a radio cabinet. Although it was small enough for homes, it was heavy and required its own condenser. A year later, General Electric patented 32 prototypes for improved self-contained room coolers. In 1931, H.H. Schultz and J.Q. Sherman invented the first room air conditioner; it sat on a window ledge, similar to portable units today.

Since 1947, AC units became more compact and cheaper. In that year, 43,000 systems were in use. By the 1960s, most new homes in the United States were built with central air conditioning. By then, electric air conditioner window units were affordable and had come down in price from the early days; a 1938 Chrysler unit cost $416 ($8,730.49 today). By 2009, the Energy Information Administration reported that 87 percent of all American households used AC units.

Today, heating, cooling, and ventilation systems are installed together as HVAC systems that work to distribute regulated temperatures throughout modern buildings. In upcoming blog posts, we will learn more about the future of HVAC and the energy efficiency measures that commercial, industrial, and institutional facilities can make to improve their facilities. Updating your (sometimes historic) HVAC system is a key part of most energy saving retrofits. Our experts at RENEW are in tune with the most innovative HVAC technologies on the market and we can install, run, and maintain these systems in your buildings, lowering your carbon emissions and reducing your energy bills without affecting your bottom line.
