Homes

Energy-efficient homes can be more comfortable, cost less to operate, and have higher resale value than their 'standard' counterparts. Today there are a wealth of new materials, skilled professionals, and analytic techniques to help new and existing homeowners in California and across the country green their homes and enjoy the benefits.

    This Zero-Net Energy (ZNE) home – now built and occupied in Ontario, California – demonstrates to the Southern California homebuilder community that ZNE homes can be constructed using prevalent building practices and sold for a reasonable incremental cost.

    The main tasks of this project were to collaborate with a progressive expert homebuilder to design and construct a ZNE home based on mutually agreed upon technologies and practices, learning together to help overcome existing market barriers to ZNE homes.

    Some of the key findings of this project include ...

  • Design Guidelines: Skylighting Guidelines
    February 23, 2014
    1 comments

    The Skylighting Guidelines, 2nd edition, were prepared to help designers optimize the use of skylights in commercial and industrial buildings. Many of the lighting principles covered here are also applicable to residential buildings. They describe opportunities for high quality lighting design and explain how to integrate skylights with the design of other building elements. They show how to estimate the potential energy savings and cost savings. Finally, they help designers avoid mistakes that could reduce the value of a skylight design.

  • Design Brief: Central DHW Systems in Multifamily Buildings
    January 5, 2010
    1 comments

    Domestic water heating (DHW) accounts for a significant share of multifamily building energy use, especially in California's coastal towns. While each new construction project will have a different ratio of energy end uses, one can look at the existing building stock to get an idea of how much is attributable to DHW systems. According to the Department of Energy's Residential Energy Consumption Survey (RECS), DHW accounted for around 32% of overall energy use for existing multifamily units in the late 1990's.
