This monograph provides information about six non-residential buildings that were designed and built to perform at zero net energy (ZNE) consumption over the course of a year. Each has proven to be successful at achieving that level of performance, or better, for at least one year of post-construction occupancy.

Zero net energy (ZNE) buildings represent a new paradigm in building design—providing super-efficient structures that generate as much energy as they consume over the course of a year. This approach to design has the potential to make massive inroads into the total amount of greenhouse gas (GHG) emissions associated with building energy use supplied by nonrenewable, carbon-based sources of power. Heightened concerns about the GHG issue are driving and transforming the leaders within the building industry to target this new level of building performance.

For decades, California has had the reputation of being the incubator and early adopter of transformative ideas and of demonstrating their practical feasibility. This reputation is certainly well-earned in the areas of energy and the environment, with numerous examples of state policy initiatives supported by both public and private sector activities. California has been a leader in energy efficiency, for example, dating back to the days of the “energy crisis” of the early 1970s.
