If you are int he market for something unusual, take a look! This is a gorgeous home made from sustainable Southern Yellow Pine logs, floors and trim. It is renewed at a greater rate than it is harvested. Compared to other building materials converting a tree into sawn lumber requires far less energy with lower CO2 emission.
The home is oriented with a solar space facing east to capture the sun in the heating season with large enough overhangs to prevent sun from penetrating during the summer. The envelope design of a home within a home separated by an air space with an insulated concrete form (ICF) foundation that serves as a heat sink. Convection currents of air between the two walls heat and cool the home, Winter heating bills are modest for a 3,000 sf home.
Currently the homes does not have any additional solar hot water or photovoltaic systems but is ideally situated for PV. With the tax credits the payback period is attractive. The DSIRE database maintained by NCSU Solar Center is the place to check out incentives for this and other available programs by state.
Triangle Green Homes along with Triangle Area Homesteaders hosted a meetup on Monday for members to learn about passive solar and how PV would be a good fit for this unique home.
