Natural Housebuilders Solar Active/Passive House

These homes use the Sun's energy for space heating and sometimes for heating of domestic hot water. We feel that using the Sun's energy is a more efficient method compared to the mainstream use of heat pumps.

The solar active/passive house accomplishes it's efficiency by using two systems. One is heat retention through use of lots of insulation. The second is using the Sun's energy either through high solar gain windows or solar thermal collectors outside the home. Sometimes we combine both passive solar with active (panels outside) solar.

Using these systems, we save so much energy that we can add solar PV panels to net zero out the home's electrical bill!

This is the Mehlschmidt net zero solar active house. This home actually produces more power than what it uses.		The Maechtlen cottage is made from recycled pallets re-made into a Insulated Concrete Form to give this house high thermal mass.  This is a solar passive house with a green house attached.		Wall section of the Maechtlen cottage is a Faswall ICF with 5" of foam attached for a R value of 42.  www.faswall.com
