The past year, this solar home generated 102% of its energy needs. The decision was made to tie this home to the electrical grid, however, to keep initial and maintenance costs down. Cost savings came primarily from not having to buy or maintain a bank of storage batteries, as well as a less expensive DC to AC inverter. The cost savings strategies also fit in with a Davis Energy Group goal of trying to make photovoltaic systems more affordable and attractive to the average homebuyer.

For more information on both the NightBreeze system (Alternatives to Compressor Cooling Project) and the Zero Energy Home project see http://www.davisenergy.com/projects.html. An article on NightBreeze development is in the July/Aug 2003 issue of Home Energy ("Kicking the Air Conditioner Habit"). Performance data from the home can be viewed at http://www.fsec.ucf.edu/en/research/buildings/zero_energy/livermore/index.htm

Important features for reducing air conditioner use are these trellises, which shade east and south windows from direct sun.  West windows are shaded by the front porch.

All of the permanent lighting fixtures use compact fluorescent bulbs.
