Thanks to Bloomberg Philanthropies' YCAF Grant Program, Colin Sexton and Sam Kastner built upon last year's successes by installing a functioning solar power system onto the greenhouse at the Zinsser Gardens. The solar panels provide energy to irrigate the greenhouse and nearby plots. The greenhouse and irrigation system were both constructed the previous year through YCAF funding, the irrigation system by Colin and friends, and the greenhouse by Sasha Fuller Eden Greenberg.

Community Choice Aggregation: this innovative program served Westchester residents for 10 years. It is currently not operational, but may regroup.
Sustainable Westchester is your liaison for this program and is looking for a new solution. For more information, fill out SW's interest form and select “Opt Into Clean Energy.”
You can also call SW at 914-242-4725. SW runs additional programs, including Community Solar and EnergySmart Homes.
You can get 10% off your electricity bill by subscribing to a community solar plan. Community solar is available only to customers who do not already have solar panels on their roofs.

Inside the furnace
What is a geothermal heat pump?
Under the frost line in Westchester County, the ground is 55ºF year-round.
A ground-source heat pump uses this 55º as energy to produce additional heat or cooling, depending on the season.
How does it work?
Geothermal uses electricity to pump fluid through underground piping, bringing that fluid to 55º through natural heat exchange. This 55º is used to cause a second liquid, which has a very low boiling point, to boil and turn into a gas. This gaseous refrigerant travels to the compressor, which is the heart of the system.
The electric compressor pressurizes the gas, which increases its temperature. The system then blows air over this hot coil, and in this way transfers its heat to air, warming it to the 70°F+ range that is then distributed throughout the house. The refrigerant then passes through an expansion valve, which drastically reduces its pressure. This drop in pressure causes the temperature of the refrigerant to plummet, making it ready to absorb heat from the outside again. It can conversely cool the house in summer.
There are three main types of heat pumps: air source, geothermal (ground source), and heat pump water heaters (hybrid water heaters).
