Beginning in 2014 California is launching a tsunami wave of building code revisions. The new and revised codes will accelerate building designs that achieve “comprehensive building solutions.” The goal of comprehensive building design is to integrate smart technologies, energy efficiency technologies and onsite renewable generation to reduce a building’s environmental impacts, increase control of building loads to reduce grid-stress during critical peak time periods and provide building owners and tenants increased control over the size of their electricity bill.
Zero Net Energy (ZNE)
Title 24 has the goal of promoting the implementation of zero net energy buildings. In a zero net energy building the annual energy consumption of the building is equal to the building’s annual onsite generation. Title 24 has as a goal that all new residential buildings be zero net energy by 2020 and all new commercial buildings will reach this ZNE goal by 2030.
Existing building compliance
Title 24 also applies to existing buildings that implement threshold-sized remodels or repurposing. In addition, by executive order Governor Jerry Brown has directed state agencies to achieve zero net energy for 50% of the square footage of existing state-owned buildings by 2025.
