“We wrestled with the waste and energy that go into building a new house and decided if we were going to do it, we would make the home as environmentally sound as possible,” Wisely said.

In addition to UV-coated windows that reflect heat in the summer and retain it in the winter, the home features a geothermal system, a solar array on the garage and Tesla Powerwalls. The latter store solar-generated power for use during overnight hours and in the event of electrical outages.

The geothermal system heats and cools the house as well as a small outdoor pool and spa. Solar panels power the geothermal pumps, the home’s electrical appliances and Slanga’s electric vehicle. Wisely tracks the home’s energy consumption on his phone, which has made them savvier about conservation.

“Knowing what is using the most power and when has allowed us to adjust our usage for the greatest efficiency and comfort,” Wisely said.

The house is built on a five-acre hillside lot. (Spacecrafting Photography)
