1st Wednesday: Groundsource Heat Pumps - Renewable Resources From Below

July 11th, 2012 - 8:00 am - 9:00 am - Hosted by SOM


How can buildings tap into the Earth’s unharnessed properties to create energy to sustain operations? Find out how geothermal heat pumps have been used locally and more about their suitability for building projects in NY in this interactive discussion.

The speakers will touch upon the main types of geothermal systems appropriate in NYC and the type of up-front due diligence that is necessary to select these system. The discussion will start by answering the question, “What is a heat pump?”. Various types of indoor heat pump equipment and their relative efficiencies will also be presented. The panelists will also discuss the relative costs of geothermal well systems and explore when geothermal retrofits of existing systems work. Case studies will also be presented to review lessons learned. Panelists will also discuss existing city initiatives to promote the development of geothermal heat pump technology.
