June 22, 2023/in From the Blog /by renew

RENEW Energy Partners specializes in funding energy saving retrofits for your commercial, industrial, and institutional buildings. There are many different technologies we install to make your buildings more efficient and reduce your energy bill. One strategy for significant savings is retrofitting your buildings to house thermal energy storage.

Introduction

Thermal Energy Storage (TES) is a technology that allows for the capture and release of heat energy. This is used to regulate temperature in a space, or to store energy for future use.

There are many benefits to using thermal energy systems. It helps you save money on your energy bill, and it also helps conserve energy. In some cases, this storage system is used to generate electricity.

If you are looking for a way to save money and conserve energy, then an energy saving retrofit using thermal energy may be the right solution for you.

What is Thermal Energy Storage?

Thermal energy storage is simply the process of capturing and storing heat energy. This is accomplished by having materials absorb and store heat, and then releasing or converting it when needed. This thermal energy is stored in some surprising materials, including water, salt, sand, rocks, and specialized phase-change materials.

One of the most common ways to use Thermal Energy Storage is in a cooling system, where the captured and stored heat is used to reduce the temperature of a space. This method eliminates excess heating or cooling needs due to sudden changes in temperature.

Thermal energy storage is an effective way of conserving energy, as it stores more energy than any other method available. It is often cheaper than using traditional energy sources, such as electricity, which result in major energy cost reductions for businesses.

The Benefits of Thermal Energy Storage

Thermal Energy Storage offers a variety of benefits to individuals, businesses, and governments.

Cost Savings – Thermal energy storage allows for significant energy cost savings over traditional sources of energy. When utilizing the heat energy stored, there is minimal energy waste, leading to higher efficiency of energy use.
Increased Energy Security – Stored thermal energy is frequently used during times of peak demand and unpredictability in the energy market, creating a buffer against supply disruptions.
Reduced Environmental Impact – The use of thermal energy leads to reduced emissions since the stored energy replaces energy that needs to be generated with fossil fuels.
Reliable Security – Thermal energy storage is a secure source of energy and is more reliable than other energy sources due to its significant storage capacity. This means that thermal energy can be stored for long periods of time and deployed when needed.

How Does It Storage Work?

Thermal energy storage works by storing heat energy in a medium such as molten salt, ice, or water. When stored in this way, heat energy can be used whenever it is needed.

The process of storing thermal energy is simple. Heat energy is collected from a source such as a solar panel or as waste heat from an industrial process and stored in a medium. This stored heat energy is then used to heat buildings, generate electricity, and other applications.

For example, solar energy is collected during the day and stored in large tanks of water. This energy is then used to heat buildings at night, helping reduce energy costs and emissions.

In other applications, stored heat energy is used to generate electricity. This is done by converting the stored heat energy into mechanical energy, for example by spinning a turbine that generates electricity.

Types of Thermal Energy Storage

Thermal energy storage is used in a variety of applications and comes in different forms, depending on the type of energy storage system implemented:

Latent Heat Storage – This type of storage involves storing heat energy in a phase-change material such as wax or salt. The phase transformation of the material allows large amounts of heat to be stored or released at a relatively low temperature.
Sensible Heat Storage – Involves the storing of heat energy in a substance like rocks or water. The stored energy causes a rise in temperature, which can then be utilized for various purposes.
Cryogenic Gas Storage – By using liquified gases such as hydrogen or methane, this type of storage is very space efficient, allowing for the storage of high amounts of energy in a small space.
Molten Salt Storage – Salt has a very high heat capacity, and can store and release large amounts of energy, making molten salt storage one of the most popular forms of thermal energy storage at a grid scale. Each type of thermal energy storage has its own advantages and disadvantages and should be chosen based on the specific application.

Economic Incentives for Commercial Thermal Energy Storage

To help businesses utilize these systems, many governments have introduced economic incentives. These can be in the form of subsidies, tax credits, and other incentives to help businesses offset the upfront costs of implementing a thermal energy storage system.

In some cases, businesses and building owners may qualify for low-interest financing programs or other loan programs to help them purchase and install thermal energy storage systems. These programs vary depending on the location and are very effective for businesses to adopt thermal energy systems.

In addition, local regulators usually have specific regulations for installing a thermal energy storage system. Knowing the laws of your state will help you plan and install the system in a responsible way.

RENEW Energy Partners is a long-term decarbonization partner with experience guiding building owners through technology and emissions regulations, identifying and utilizing the best technology and corresponding tax credits for each job, and funding and managing carbon-saving projects from start to finish.

The Future of Thermal Energy Storage

There is growing interest and investment in thermal energy storage systems as businesses and governments are recognizing and capitalizing on their potential to save money and conserve energy.

In the future, advances in technology will likely mean better performance from thermal energy systems at lower prices. This will make them an increasingly appealing option for businesses and consumers.

In addition, solar energy storage is gaining interest due to the intermittent nature of solar energy production. As interest in these applications continues to grow, there is potential for solar powered thermal energy systems to become an increasingly important part of the energy mix.

Thermal energy storage is an effective way to reduce energy consumption, save money, and increase energy security. With increasing demand for energy and the environment, TES is a great option for businesses, manufacturers, and governments.

Employee Profile: Charlie Tryon

April 28, 2023/in From the Blog /by renew

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.

Master Service Agreement: The Key to Decarbonization

April 21, 2023/in From the Blog /by renew

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:

Reassigning growth capital from carbon-heavy resources
Using operational cashflow savings
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

April 13, 2023/in From the Blog /by renew

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

March 16, 2023/in From the Blog /by renew

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.

The Future of HVAC Retrofits

February 16, 2023/in From the Blog /by renew

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:

Lighting: The Easiest Energy Saving Retrofit

November 4, 2022/in From the Blog /by renew

RENEW Energy partners specializes in helping fund your energy saving retrofits for your commercial, industrial and institutional buildings. There are many different technologies we install to make your buildings more efficient and reduce your energy bill. One of the best places to start is with an energy saving LED lighting retrofit.

A Brief History of Lighting:

Illumination has come along was since 1880, when the Edison Electric Company started marketing their newest product, a lightbulb with a carbonized bamboo filament. Eventually, the bamboo filaments changed to tungsten, and after a while the first incandescent bulbs were invented, which began to be distributed in the 1940s.

Modern incandescent bulbs, like their predecessors, are not energy efficient – less than 10% of electrical power supplied to the bulb is converted into visible light. The remaining energy is lost as heat. These low-efficiency incandescent bulbs are still commonly used today because they are widely available, have a low first cost, are easily incorporated into electrical systems, and have a low voltage operation in battery powered devices.

These incandescent bulbs could easily be the ones lighting your buildings. If that is the case, 90% of your lighting bill is being wasted! The good news is, a lighting retrofit is one of simplest ways to increase your energy efficiency, save money on your energy bills, and lower your carbon footprint. RENEW Energy Partners is here to provide the funding you need to do so.

The Future of Energy Saving Lighting:

A great energy savings retrofit starts with lighting. The best way to reduce your lighting costs is to switch to LED lighting (LED stands for light-emitting diode). Although once known mainly for indicator and traffic lights, LEDs are today’s most energy-efficient and rapidly developing lighting technology. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs.

LED lights are such a great energy saving retrofit that most if not all new buildings use LED lights. However, 1,000’s of buildings have yet to convert. Energy-saving LED retrofitting is great because they have great payback (usually less than a few years), are now a proven technology with little performance risk, and they offer significant maintenance savings since they last 50 to 100 times longer than incandescent bulbs.

If you are exploring an energy savings retrofits start by looking up, if you don’t see LED lights than that is where you should start.

Once you have installed new bulbs, the next step to make your building more energy efficient is to install lighting controls. The technology varies, but these are effectively a dimmer switch. Instead of only two options for lighting (on and off), building operators can have lights running anywhere on the gradient between 1%-100% use). This allows for more efficient lighting settings, in addition to more efficient bulbs. In fact, using dimmable LED lights doubles the life of your bulb, saving on energy costs even further.

Another way to enhance your energy saving retrofit is to install motion sensors. Motion sensors allow your lighting to turn on when they detect movement and to turn off if they have not detected movement for a while. This helps save energy by automatically shutting of lights in empty rooms. The same effect is achieved with lighting timers if your building runs on a regular schedule.

Dimmers, motion sensors, and lighting timers are controlled using a smart lighting system. When these are incorporated into your building management system, they allow you to control the lighting for your entire building on one screen. In addition, some smart lighting systems have analytics tools so you can monitor your energy use in real time and compare it to your past energy use.

Implement Energy Saving Lighting with an Energy Service Agreement

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!
