High Performance Demonstration Homes
Daybreak, Utah

Passive Solar Shading
PVT System |
Four high performance homes were featured in the 2008
Utah Parade of Homes, held August 2008. These homes were made possible by a partnership with
Kennecott Land, the Salt Lake Home Builders Association, and four builders (Gold
Medallion, Rainey Homes, Holmes Homes, and Liberty Homes), with technical
support from the U.S. DOE Building America and Solar America Cities Programs,
Utah Clean Energy, Salt Lake County and Salt Lake City. Kennecott Land, which
already requires participating builders to meet ENERGY STAR criteria for new
construction, is participating in the demonstration project as part of its
commitment to advancing sustainable building practices at Daybreak. The
demonstration projects will help inform future building design criteria
developed by Kennecott Land for new homes built at Daybreak. The demonstration
homes qualify for a federal new homebuilder tax credit ($2,000) and utility
incentives from Rocky Mountain Power and Questar Gas.
The four homes feature examples of highly energy efficient design practices and
systems, and renewable energy technologies, including:
- Passive solar
- OASys Indirect-Direct Evaporative Cooling
- Heat Recovery Ventilators
- Structural Insulated Panels (SIPs)
- LED lighting
- Tankless Water Heaters
- Integrated Photovoltaic and Solar Thermal Panels (known as 'PVT')
- Blown-in Blanket Insulation System
- Spray foam insulation
- Energy Star Appliances
- Low-flow plumbing fixtures, and water efficient outdoor landscaping
Each of the four demonstration homes is designed to consume at least 50% less
energy than a typical home built to industry-standard construction practices.
The homes were designed and built to showcase how the energy performance of new
homes can be significantly improved by application of energy efficient design
practices, such as orienting the home and incorporating solar shading on
windows, with tight envelopes, advanced heating and cooling systems, and energy
efficient lighting and appliances. One of the homes features an integrated
photovoltaic-solar thermal system (known as ‘PVT'), which makes it capable of
achieving net-zero energy consumption on an annual basis. Another incorporates
advanced, indirect-direct evaporative cooling system that uses 70% less energy
to provide cooling, while delivering a continuous supply of fresh, filtered air
into the home.
The homes also feature drought-tolerant landscaping combined with drip
irrigation to reduce exterior water consumption. Each of the homes will be
monitored by the Building America Team to evaluate the performance of each
technology, and actual energy performance of the occupied homes.
