The Utah House is about 60% more energy efficient than regular houses
its size, earning it the government’s Energy Star rating. Saving energy
saves money and reduces the use of nonrenewable, pollution-causing
energy sources.

Energy Efficiency Design Features 

South-facing windows maximize heat gain from low-angle winter sun.

Tile floors create thermal mass to absorb that heat.  In the summer,
large eaves and a light shelf block high-angle sun from coming into
the home.

Clerestory windows provide natural
light.

Daylighting rooms throughout the
home reduces the need for electrical
lights.

1Kw thin film photovoltaic (PV) panels on the roof generate 20-25% of
the house's electricity from sunlight.  An inverter, located in the closet,
converts electricity from solar panels from DC to AC for use in the
house.  Any extra energy generated is sold back to the power company. 

Natural light tubes in the bathroom, utility room, and hallway bring
daylight into the northwest corner of the house.

Compact flourescent lighting (CFL) located over work areas can be
dimmed for optimal lighting. CFLs us 66% less energy than
incandescent bulbs and save up to $30/bulb in lifetime electricity costs.

Energy Star appliances use less energy and water than other models.
