Air-Source Heat Pumps (ASHPs)
Air-source heat pumps make it possible for your multi-family building to stay comfortable year-round, while saving energy and reducing your carbon footprint. Unlike conventional HVAC systems, heat pumps are powered by electricity, using well-established technology to move heat from outdoor air to indoor air. When powered by zero-carbon electricity, ASHPs provide space heating with almost no greenhouse gas emissions. ASHPs are especially effective for space heating in mild climates.
ASHPs: Quick Facts
- Works like an air conditioner, without ductwork or noise, that can also run in reverse to provide heating
- Has an outdoor unit and one or more indoor unit(s)
- Cold climate heat pumps can provide heat down to -13°F
- Cold climate specification (NEEP) evaluates cold climate performance, which is necessary for NYSERDA rebate
- Typically installed with a backup heating system, full heating replacement is not required
- Ductless systems provide zone control
Building Performance: Energy Efficient Envelopes
How do I make my building more energy efficient?
Energy-efficient homes not only cost less to operate, but are healthier, more comfortable, and better for the environment. Below are tips to help you get started and learn how to save energy at home, with resources from NYSERDA.
Building Energy Audits and Ratings
Take the first step—learn about the energy performance of your home by getting a home energy audit or rating. Audits and ratings identify where your home is wasting energy, how systems are working, and what may be needed in terms of upgrades.
Seal and Insulate Your Building
Some of the most common air leakage points are in attics, basements, doors, and windows. There are multiple ways to effectively seal your building, depending on your budget.
Air that leaks through your building’s outer walls, doors, basements, and windows wastes a lot of energy, increases your energy bills, and can lead to an unhealthy indoor environment. If done properly, air sealing and insulation work hand in hand to reduce the risk of moisture-related mold and rot, boost indoor comfort by eliminating drafts, and reduce outside noise, among many more benefits. It is important to note that not all air leakage is bad. A building that is sealed too tightly can result in increased levels of carbon monoxide from combustion appliances, including furnaces, water heaters, and gas stoves, condensation/humidity issues, and stagnant air.
Air sealing your building effectively helps you reduce heating and cooling costs. When done properly, air sealing also reduces the risk of mold and rot, eliminates ice damming on your roof, increases the comfort of your building by reducing drafts, and improves indoor air quality by preventing dust and pollutants from entering the building.
