Poorly insulated windows and doors increase the amount of energy lost via building emissions, which is both damaging to the environment and organizations’ bottom line when utility bills are due. There are several basic steps nonprofits can take to improve building insulation to curb energy loss, including installing weather stripping on windows and gasketing and sweeps on doors. Both measures help create a better seal to reduce the transmission of unconditioned air, reduce the heating and cooling load, and reduce energy consumption.

Our team can help your organization achieve energy savings and reduce carbon emissions through projects ranging from small building renovations to building design and construction. IFF has helped a variety of nonprofits in the Midwest upgrade their buildings by providing loans and real estate advice for green facility projects, including feasibility assessments and cost estimates. Sustainable initiatives for nonprofits include electric vehicles, geothermal energy, solar energy, window insulation, roof replacements, energy-efficient appliances, and more. Not only do these improvements result in long-term savings and can pay back the initial investment, but they also improve the benefits of your facility for staff and the community while contributing to environmental sustainability.
Energy Efficiency & Nonprofits
Geothermal energy is a renewable resource that can be harnessed to heat and cool facilities using pumps that use the earth as a temperature exchange medium. Because the temperature underground is consistently 50 to 60 degrees Fahrenheit, water can be pumped through pipes below ground level to absorb the heat, then compressed in a heat pump and released through building air ducts. The same is true for cooling during summer months, with the process reversed. Heat from the air is drawn from the building and carried off by the water or other coolant in the pipes and deposited back into the ground. The process does not emit greenhouse gases, and once the system is installed, ongoing operating costs are low since no fuel is involved.
Another way nonprofits can increase the sustainability of their facilities through HVAC modifications is to replace gas/oil-fired systems with electric heat pump systems. Electrification works best in buildings that are both well-insulated and airtight, which can be a complex process to achieve in older buildings, but doing so results in a more energy efficient facility that costs less to operate.
Solar power is a renewable source of energy with significant upfront costs for installation, but those upfront costs can result in long-term cost savings for nonprofits while also drastically increasing the environmental sustainability of their facilities. The installation of solar panels is likely to be easier to accomplish for nonprofits building new facilities, since the structure can be optimized in the design phase to support the infrastructure needed, but it’s entirely possible for organizations renovating their facilities to install solar panels to reduce their energy usage and costs – particularly given the availability of government incentives and grant programs that help subsidize the cost of installation.
During construction or renovation, planning to use materials that are eco-friendly and energy efficient can be just as cost-effective as other materials. There is also a significant difference in carbon impact in using higher impacts materials like aluminum and zinc as opposed to plywood or linoleum. The construction material pyramid can give insight into the carbon footprint of various materials.
Electric vehicles have a smaller carbon footprint than gas-powered vehicles. If it’s time to purchase a new vehicle for an organization, consider if an electric or hybrid option could work.
Installing energy efficient appliances is another way nonprofits can reduce their monthly operating costs and help the environment. Energy Star-certified appliances like washing and drying machines, refrigerators, and water heaters – among other examples – reduce greenhouse gas emissions, water usage, and dependency on unsustainable fossil fuels. While the cost savings produced by Energy Star-certified appliances are small, the potential for collective impact is large if such appliances become the standard. The EPA estimates that if every appliance purchased in the United States this year were Energy Star-certified, the combined reduction in greenhouse gas emissions would be equal to that of 215,000 cars on the road.
Fresh, clean water is one of the world’s most precious resources, and it’s becoming scarcer due to climate change. One way nonprofits can reduce water usage in their facilities without sacrificing performance is to install low-flow plumbing fixtures (e.g., toilets, faucets) that reduce waste. Low-flow fixtures are designed to produce water pressure similar or equal to older fixtures, but with drastically less water used. According to the U.S. Environmental Protection Agency (EPA), replacing a sink faucet alone saves an average of 11,000 gallons of clean water over the faucet’s lifetime. Tankless hot water heaters won’t change how much water is used, but they are much more energy efficient than tank storage heaters. For nonprofits that install new efficient fixtures throughout their facilities, this can add up to meaningful cost savings over time while contributing to a more sustainable future.
Some smaller changes can make buildings both more energy efficient and more comfortable to use. Heating and cooling unused spaces, or maintaining temperatures that are higher or lower than what’s needed for occupants to comfortably use those spaces, contributes to energy inefficiency in facilities and unnecessarily increases carbon emissions. Smart thermostats help mitigate both issues by automatically adjusting heating and cooling temperature settings for optimal performance. This eliminates the need for staff members to manually adjust the temperature and can provide the organization with equipment use and temperature data to continue optimizing settings for peak energy efficiency.
According to some estimates, lighting accounts for approximately five percent of global carbon dioxide emissions, making installing lights that are as environmentally friendly as possible a high priority. Compared to old incandescent lights, LED lights can achieve energy savings of as much as 75 percent and last 25 times longer, making them an eco-friendly option for nonprofits renovating an existing facility or building new. An added benefit of the long life of LEDs is that they save significantly on labor time spent changing burned out bulbs.
Another related modification organizations can make to increase the environmental sustainability of their facility is to replace light switches with room occupancy sensors to prevent lights from remaining on when rooms or other spaces within the facility are not in use. Similarly, exterior lights can be placed on digital timers or photo sensors to minimize their use when unneeded.
Replacing a roof is a sizable investment, but it’s one that’s absolutely critical to extending the lifespan of facilities by preventing water damage, rotted wood, and more. Nonprofits should periodically have the roof assessed, and, if it’s determined that repairs or a total replacement is necessary, prioritize the project to avoid more costly issues later on due to deferred maintenance.
There are several options for membrane roof replacement (commonly called “flat” roofs). Materials such as TPO, PVC, and EPDM vary in cost, lifespan, and carbon/chemical content, but the most important aspect for environmental impact is color: the roof should be white or as light as possible, to reflect solar gain and keep the building cooler in summer heat. Membrane roofs are compatible with rooftop solar panels and “ green roofs ” that reduce groundwater runoff, improve thermal insulation, and lessen the effect of heat islands .
When thinking about replacing a roof, take a look at how much insulation exists and consider adding more. Most buildings lose more heat from their roof (35%) than from walls (25%), windows (10%), or doors (15%), so investing in good insulation, either during a remodel or a new build, can add up to real savings.
Insulation strength is measured in R-value, with a higher number providing the most protection from heat loss or gain. Buildings with attics usually have insulation installed on the ceiling (the floor of the attic). Check the attic: if the building has loose or blanket (batt) insulation but the ceiling structure (joists) are visible above it, more is needed. Insulation should cover the tops of the joists and be R-40 minimum.
Buildings with flat roofs will typically have insulation directly under the roof membrane, usually rigid foam boards. If a roof replacement or installation is imminent, consider the opportunity to add more insulation to raise the R-value to R-30 or even more, if possible. Adding a few inches of foam board during a roof replacement is a small cost in terms of the overall project and can significantly save on both heating and cooling costs. It’s also a good idea to install a white or light roof.
