Intervale Lowlands Preserve Energy Report
At Intervale Lowlands Preserve we try to set an example for sustainable private land stewardship. Over the past three years between 2012 and 2015, the residential buildings on the preserve have used minimal petroleum products for heating, cooling, and other energy demands due, in part, to energy efficient construction, the installation of solar panels, and the use of geothermal heat pumps for heating. Over this time period, these facilities have saved 90,064 kilowatt hours (kwh) of electricity compared to the energy use of a similar houses built to code.The solar panels on the preserve produced 32,717 kwh of electricity to offset power usage. The combination of energy savings and electric generation equates to an equivalent CO2 reduction of 93.3 tons of carbon between August 2012 and April 2015. These measurable savings to non-renewable resources are the result of LEED Platinum certification of the main residence and net-zero post-construction CO2 demand of both buildings. We have calculated these values based on data available from the preserve using the energy monitoring program Powerhouse Dynamics (Newton, MA).
Here are some highlights about the preserves energy production and usage.
We did not achieve our goal of net zero energy budget in 2014 due to construction, and subsequent construction-related energy demands, of a guest house. Much of the energy that we produce comes from solar panels. On August 7th, 2012, our first arrays of solar panels were activated. The guest house received a solar panel array on November 4th, 2014. The installation of a second array of panels is nearing completion and expected to be activated in mid-July of 2015. Curt Snyder at Crest Solar was the installer of the solar systems at Intervale Lowlands Preserve. For more information, contact Crest Solar

New York State currently offers great incentives for homeowners to install solar panels on their home. For more information, visit http://www.nyserda.ny.gov/
