California introduced energy efficiency building standards in 1978 - standards that established minimum requirements for insulation, windows, appliances, roofs and other features that make up today's modern home. The Standards are periodically updated to take advantage of newly developed technologies, improved appliances and emerging building techniques.
Thanks in part to the Energy Efficiency Standards for Residential and Nonresidential Buildings, California today is one of the most electricity efficient states in the nation on a per capita basis. Many other states have followed California's lead to incorporate innovative energy efficiency ideas into new homes.
Here are some of the modern choices you can make to construct a house that is more comfortable, safe, quiet and energy efficient - a home that can also be less harmful to the environment.
