U.S. Department of the Interior
Acadia National Park (Bar Harbor, Maine)
The National Park Service (NPS) at Acadia National Park is removing the existing inefficient 20,000 square foot maintenance complex, four temporary trailers and 11 outbuildings, and constructing a new LEED Silver designed 32,000 square foot facility on the existing McFarland Hill headquarters campus in the town of Bar Harbor, Maine. However, the current funding allocation for this project does not include the capital improvements needed to move towards a net-zero emissions building or park. The proposed energy conservation measures supported by the AFFECT grant are a roof-top photovoltaic (PV) system and twelve bidirectional electric vehicle charging stations (EVSE).
The addition of a PV system, right-sized for Maine's climate and with financial feasibility in mind, would move the building and park towards net-zero emissions by generating over 50% of the new facility's energy use.
By generating direct energy cost savings of $60,800 per year, the AFFECT energy conservation measures (ECMs) will pay back in 16.1 years and will continue to accrue savings for the park for the remainder of the system's useful life. The AFFECT-funded PV project would generate 308,384 kWh/yr and reduce greenhouse gas emissions by 74,654 kg CO2e while simultaneously furthering the park's understanding of the technology and benefits.
U.S. Department of Commerce
Mauna Loa Observatory (Waimea, Hawaii)
On Nov. 28, 2022, all measurements and radio transmissions from Mauna Loa Observatory (MLO) ceased when lava flows from the 12-day eruption of the Mauna Loa volcano cut the power line and buried over a mile of the access road to the observatory. Since November, access to the site has been limited to costly weekly visits by helicopter to collect limited atmospheric data. The modified observatory operations are powered by existing solar panels, which can only sustain roughly 10% of pre-eruption operations.
The National Oceanic and Atmospheric Administration (NOAA) requests support of $5.09M from the AFFECT program to install solar panels and batteries at the observatory to make the facility net zero emissions, which would bring the critical atmospheric science instrumentation back online and significantly improve the site's operational climate resiliency. Since MLO already captures its water needs from roof systems, the observatory would be the first Department of Commerce facility to be net zero for both electricity and water. As the observatory is considered the definitive source for documenting the increased atmospheric burden of fossil fuel emissions, this project has the unique ability to eliminate 100% of the combustion of fossil-fueled electrical power to make those critical measurements.
U.S. Department of Transportation
Kahului Airport (Kahului, Hawaii)
The Federal Aviation Administration (FAA) is planning energy and water efficiency improvements and a solar photovoltaic (PV) installation at the Maui Air Traffic Control Tower (ATCT) in Kahului, Hawaii. The project includes replacing the site's 35-year-old HVAC system and associated controls equipment with high-efficiency equipment, making enhancements to the building envelope including window replacements, and installing a new 75-kW solar PV system, an advanced metering system, and water conservation measures.
These projects will reduce energy consumption by 118,960 kWh in the first year of operations and reduce energy costs by $1,754,012 over the 25-year life cycle. Water consumption will be reduced by 500 kGal/year or 20% of total annual water consumption with a 30% reduction in annual water costs. The PV system will generate 47% of facility energy needs on site and help increase in the facility's CFE consumption from 20% to 67%.
FAA has already released the solicitation for this project and anticipates awarding by the end of 2023. AFFECT funding would be applied to the contract as a modification at the time of award, allowing FAA to make additional progress against federal energy and climate resilience requirements set forth under EPAct 2005, EISA 2007, Energy Act of 2020, and E.O. 14057.
U.S. General Services Administration
Ronald Reagan Building and International Trade Center (Washington, D.C.)
This project aims to electrify the heating and domestic hot water service at the Ronald Reagan Building and International Trade Center (RRBITC) facility in Washington, DC, replacing the building steam provided from the General Services Administration (GSA) Heating, Operation and Transmission Division (HOTD). RRBITC is part of a $93 million energy savings performance contract (ESPC) scheduled for final acceptance on April 30, 2024. This AFFECT funding will ensure that the full electrification project scope can be included as a modification to the existing ESPC and be accomplished within the existing performance period.
A combination of heat pumps and supplemental electric boilers will reduce greenhouse gas (GHG) emissions annually by 2,242 metric tons of CO2e, which is in addition to the 13,702 metric ton reduction from the base ESPC. The base ESPC is reducing energy consumption at the RRBITC by 39.1%, and the electrification of the building will improve the building energy reduction to 47.8%. This project is also estimated to reduce annual utility expenditures by over $160,000.
RRBITC is the largest building in GSAs portfolio and the first building on the HOTD plant that will be converted to comply with the Building Performance Standard, and it will serve as a blueprint for future building conversions. Due to the size of this facility, removing it from the HOTD system could have a domino effect in electrification of the remaining buildings on the system.

James V. Forrestal Federal Building (Washington, D.C.)
The Forrestal Windows Upgrade project will promote the Department of Energy's (DOE's) efforts to be a leader in net‐zero building projects. The project, as part of a larger energy savings performance contract (ESPC), will upgrade more than 86,000 square feet of windows as an innovative response to obtaining thermally efficient windows at affordable costs with limited impact to building occupants and operations.
This project will transform the windows from original 1960's single‐pane to add double‐pane, low‐e secondary windows on the interior of the building. The thermal performance of the windows will be quadrupled by the project. Quadrupling the thermal performance of the windows will result in reduced energy consumption across facility systems. The largest energy savings will be seen in the building HVAC systems with reduced cooling and heating loads. Secondary savings will occur through reduced supplemental heating and cooling methods ranging from supplement fan coil units to plug‐in fans and heaters. Forrestal energy savings will occur in electrical consumption, steam consumption, and chilled water consumption.
The completion of this project will save DOE an estimated $267,000 per year and reduce greenhouse gases by 12% (scope 1) and 27% (scope 2).

The outcome includes expanded PV and BESS capacity, serving critical facilities during outages, reducing carbon emissions, and advancing net-zero objectives.
Marine Corps Air Station Beaufort (Beaufort, South Carolina)
This AFFECT funding will support a 1.16 MW-AC solar photovoltaic (PV) carport over the parking lot adjacent to the Marine Corps Air Station (MCAS) Beaufort gymnasium and dining facility. This energy conservation measure (ECM) is part of a utility energy services contract (UESC) with Dominion Energy and will generate renewable electricity to offset 100% of the gymnasium's commercial energy usage and 77% of the commercial energy usage at the dining facility, supporting net-zero facility efforts at the installation, improving energy diversity, and reducing carbon emissions from local power plants. This effort expands on the ongoing net-zero efforts at the installation gymnasium, which include solar hot water production, water to water chiller waste heat reclamation, rainwater collection, and 25-KW of solar PV. The UESC also includes more than 11,000 LED lighting retrofits to reduce facility energy usage across the installation, and electrical distribution improvements as the first phase of a comprehensive sitewide microgrid that will tie in alternative fuel sources and renewables to reduce greenhouse gas emissions and provide climate resilient infrastructure in the event of a commercial outage.
The AFFECT funding will supplement the cost of the 1.16-MW solar PV system, which is the optimal size needed to support the site's gymnasium and dining facilities but is not currently fully financeable in the UESC. Combined with the other already self-amortizing ECMs in the UESC, the requested grant funding will reduce project payback from 39.3 years to 12.1 years, allowing the entirety of the project to maintain a payback of less than 25 years.
Naval Air Station Whidbey Island (Oak Harbor, Washington)
Steam distribution losses are the top use of building energy at Naval Air Station (NAS) Whidbey Island in Oak Harbor, Washington, and this project will enable the base to eliminate its natural-gas-fired steam plant and miles of distribution system and install new electrified heating and cooling systems at the building level. The funding will also allow NAS Whidbey Island to upgrade already undersized electric feeders, enabling the electrification of buildings on these feeders, targeting additional load for immediate electrification, and readying the base for further electrification. Additionally, the Navy will utilize an energy savings performance contract (ESPC) and $4.35 million in utility incentives to reduce fossil fuel dependence and greenhouse gas emissions and increase resilience at the base by adding solar photovoltaics (PV), heat pumps, a microgrid, small-scale carbon capture, LED light fixtures, and lighting controls.
This is an all-or-nothing decentralization project, as the greatest cost savings will come from removing the steam plant and its operations and maintenance (O&M) costs. These savings will fund O&M of the new heat pump systems and provide approximately $1 million per year in additional savings. The project will reduce fossil fuel use by 60%, save 5.5 million kg of CO2e, and eliminate over 66,000 MMBTU per year of natural gas wasted via steam distribution system losses.
The utility grid that feeds NAS Whidbey Island is currently 35% renewable. The Washington State Clean Energy Transformation Act requires net zero carbon emission by utilities by 2030; therefore, each additional electrified building will be a net‐zero building in 2030 with no further action required by the Navy.
Naval Submarine Base Kings Bay (Kings Bay, Georgia)
This project will enhance Naval Support Activity Mid-South's (NSAMS) resilience and energy efficiency through a utility energy service contract (UESC), incorporating a larger (6-MW) photovoltaic (PV) array, air handler replacements, and additional chiller upgrades. The AFFECT grant will address funding shortfalls, enabling an expanded solar PV array and battery energy storage system to offset 18% of the site's grid consumption, effectively removing 25 NSAMS facilities from the grid and contributing significantly toward achieving net-zero goals. The project aims to enhance energy and water resilience, security, conservation, and load management, aligning with federal goals to transition infrastructure to zero-emission, carbon pollution-free electricity and achieve net-zero emissions by 2050.
Naval Support Activity Mid‐South (Millington, Tennessee)
The Utility Energy Service Contract (UESC) project will modernize Naval Support Activity Mid-South's (NSAMS) infrastructure coupled with on‐site electric generation sources to provide continuity of critical mission during electric utility outages and enhances the resilience of the installation.
The AFFECT funding will help reduce the site's overall energy consumption, lower NSAMS's carbon footprint, and steer the entire base towards net‐zero. The project economics currently support 4 MW of on‐site renewable solar photovoltaic (PV) generation and a 1.5 MW/3 MWh battery energy storage system (BESS) to provide energy resiliency for the site's most critical facility, Building 769. This battery can support the building's most critical loads in the event of a loss of power for two hours, after which an existing diesel fuel backup generator would have to be utilized.
The AFFECT funding would help bridge the gap needed to install up to 6 MW of solar PV and up the size of the BESS to 1.5 MW/6 MWh. This increased size would allow for the battery to serve Building 769 for a minimum of 4 hours. The funding would also help expand the HVAC system and chiller plant improvements.
The project will displace 18% of the site's current grid purchased electricity by installing onsite renewable generation sources (PV and BESS).
U.S. Army Garrison Wiesbaden (Wiesbaden, Germany)
This project will add solar photovoltaic (PV) arrays on six soldiers' barracks buildings, one command center, and one office complex at Clay Kaserne, U.S. Army Garrison (USAG) Wiesbaden, Germany. USAG Wiesbaden is the home of U.S. Army Europe and Africa Headquarters, servicing 15 installations and housing areas in and around Wiesbaden. The Wiesbaden energy savings performance contract (ESPC), currently in the development/comment resolution phase, had to remove this solar PV energy conservation measure (ECM) due to unfavorable economics including escalating interest rates. However, by incorporating AFFECT grant money into the ESPC, a contract modification would be issued to expand the scope of work to include PV and allow for faster contract execution and better financials.
The PV system will provide 38% of building power and offset 181 metric tons of CO2 annually (the equivalent of 392,144 lb. of coal burned annually). The solar PV arrays will average 50–75 kW DC per building and maximize the available roof space. The barracks, on average, will be 38% closer to net-zero, with the highest reaching 75% of net-zero. Bringing the eight buildings closer to net-zero is just one piece of USAG Wiesbaden's energy independence goal. By applying $1.4 million of AFFECT funding to the ESPC, Wiesbaden will be able to provide greater energy security to meet mission operations and help meet Executive Orders 14057 and 14008 goals.
U.S. Department of Energy
Hanford Site (Richland, Washington)
This project aims to replace evaporator diesel-powered boilers with electric boilers in the Waste Treatment and Immobilization Plant (WTP) at the Department of Energy (DOE) Office of Environmental Management (EM) Hanford Site in Richland, Washington. The Hanford site has one of DOE's largest, most complex and energy-intensive missions—treating 56 million gallons of legacy tank waste stored in 158 of the 177 underground waste tanks across the site. The WTP uses vitrification, a process where waste is combined with glass formers, fed to a furnace known as a glass melter, and turned into glass. DOE will use AFFECT funding to partially fund the addition of a new electric steam plant to supply steam for the WTP vitrification processes.
Hanford currently accounts for approximately one-third of EM's total carbon emissions. When the WTP begins operating, it will roughly double Hanford's energy demands. Thus, addressing emissions at these facilities is key to Hanford's net-zero approach and helps create a waste treatment process that is less impactful to global climate change. This project has the potential to save DOE $15.6 million in fuel costs per year in full operations, saving $904 million in fuel costs over the life of the mission (at 2023 fuel prices with no escalation). Further, this proposal would help Hanford reduce its future greenhouse gas footprint by 43.3 million kg CO2e per year and 2.5 billion kg CO2e over the 60-year mission life.
Princeton Plasma Physics Laboratory (Princeton, New Jersey)
This project will focus on the Princeton Plasma Innovation Center (PPIC) building, aiming to implement energy conservation measures (ECMs), including a geothermal system funded by the AFFECT grant, to achieve a fully electrified and net-zero emission facility. The requested funding will significantly expand the geothermal bore field, enabling the system to meet 100% of the building's annual and peak heating and cooling loads. The grant will contribute to showcasing the PPIC as a sustainable model, incorporating ECMs like heat recovery chiller-heaters and energy-efficient lighting, with data on building performance available both onsite and online. Additionally, the funding is expected to provide a 16% increase in energy savings, extend the geothermal system's lifespan, and support the PPIC in becoming a prominent example of innovative technology for electrifying buildings.
SLAC National Accelerator Laboratory (Menlo Park, California)
SLAC National Accelerator Laboratory identified facilities utilizing aged High Intensity Discharge (HID) lighting in hi-bay buildings that are susceptible to bulb explosion, energy inefficiency and challenging access for maintenance bulb replacement. SLAC started replacing lighting in 2017 and made good progress over the first 3 years, however work stalled due to inflationary pressure.
This project will reduce lighting energy by approximately 90% at SLAC due to the improved efficiency of the new LED fixtures, improved luminary properties, dimming, timed shutoff and installation of wireless wall switches that will allow the lights to run approximately 10 hours per day on weekdays. Currently the HID lights remain on 24 hours, 7 days per week due to a lack of accessible switches. With AFFECT funding, SLAC can complete this lighting replacement in five buildings to help drive all these facilities to net-zero emissions.
The expected costs savings of this project is $14,599 annually, which translates to a payback period of 4.6 years. This project will also reduce greenhouse gas emissions by 42,806 kg CO2e per year.

This project will help the U.S. Department of Transportation (DOT) secure reliable, self-sufficient clean energy solutions for Federal Aviation Administration (FAA) Air Traffic Control Towers (ATCT) nationwide, critical assets for air traffic safety, yet often in poor condition and reliant on traditional power sources. The funding will support an initial site evaluation at the William J. Hughes Technical Center in New Jersey, encompassing a feasibility assessment and the creation of an assessment tool for all ATCT locations. The anticipated results include establishing criteria for clean energy-driven, self-sustaining ATCTs, offering a proof of concept for scalable, replicable net-zero energy conservation measures applicable to all ATCT sites.

Denver Federal Center (Lakewood, Colorado)
The centerpieces of this project are two renewable energy conservation measures (ECMs) – solar PV and geothermal heating and cooling. These ECMs are designed to help the GSA achieve its goals of electrification and decarbonization of the Denver Federal Center (DFC) campus.
The solar PV scope of work includes the installation of up to 13.9-MWDC ground mounted bifacial solar PV to provide up to 21.5 million kWh annually of carbon pollution-free electricity.
Additionally, GSA intends to eliminate the use of natural gas for heating in the majority of the buildings on the DFC campus by implementation of a geothermal system that takes advantage of the relatively consistent year-round ground temperature as a heat sink in the summer and a heat source during the winter. The geothermal system will provide an all-electric heating source to replace existing natural gas fired boilers. Electricity for the new geothermal heat pump systems will be provided by the newly installed solar PV panels.
