Alan's Passive Solar Home

This Pro Tour visited two sites located in Augusta and Lafayette, NJ, both of them residential homes. Each of these houses uses combinations of both passive and active renewable energy systems, including wind power, and most notably solar power.

The tour of the first site was given by architect and homeowner Alan Spector. He presented his passive solar home which has a two-story sunspace, is partially earth sheltered, and has solar hot water and PV systems which account for 75% of energy savings. This house was featured on the cover of the Oct/Nov 2014 issue of SolarToday magazine.

DeWitt Home and Tower

The tour of the second site was led by Frank DeWitt, whose home is fitted with a combination of wind and solar systems which fulfill the majority of his electricity usage. For his conventional home, he has installed a 125 ft, 10KW wind turbine and a 10KW ground-mounted solar array.

The Pro Tour concluded with a workshop, led by Alan and Frank, at the Sussex County Community College. The topic was "Energy Models vs. Actual Performance," and compared energy model projections with actual performance of active and passive solar systems in these two homes in Northern New Jersey. Active systems compared included: solar hot water, solar photovoltaic, wind turbine, and high efficiency heat pumps. Passive systems compared included: sunspace, earth sheltering, direct gain, mass walls and floors.
