KB Home, a publicly-traded home builder with its headquarters in Los Angeles, this month announced the nationwide roll out of net-zero energy home designs called ZeroHouse 2.0.  The standard KB Home with Energy Star certification is built to save homeowners about $1,000 in average annual energy costs, while a ZeroHouse 2.0 design is expected to eliminate monthly electricity charges.

Model homes with the ZeroHouse 2.0 package open this month in Tampa (shown), San Antonio, and Austin. Homebuyers in a market with ZeroHouse will be able to customize their purchase using the KB Home Studio to include options like those found in the model.

A key aspect of the ZeroHouse is solar power.  The Tampa home has both a solar thermal and solar PV (5.9 kW) system.  It achieved a minus 5 HERS rating, according to Fine Homebuilding, meaning the model will generate a surplus of solar energy under normal operating conditions.

In addition to solar power, KB Home upgraded the performance of these homes with increased insulation, upgraded HVAC systems, and dual-pane, low-e windows.

In the past, we’ve mentioned another Zerohouse, which is an award-winning prototype for a net-zero, modular, tiny home by Specht Harpman.  Today’s announcement is not to be confused with our prior coverage of the Zerohouse prototype.
