New Energy Efficiency Standards Take Effect July 1, 2014

California’s Building Energy Efficiency Standards (Title 24, Part 6) for new construction, additions and alterations will change on July 1, 2014. The 2008 standards in use today will be replaced by the 2013 standards.

The 2013 standards include several changes to residential and non-residential requirements. For example, single family homes in subdivisions of ten or more homes must include solar-ready roofs, regardless of the climate zone. Duct sealing is now a mandatory measure for residential buildings in all climate zones. Nonresidential buildings have increased low-slope cool roof requirements. In addition, compliance documents have been simplified and streamlined for easier use.

There are numerous other changes, which can be reviewed through the following resources:

Get personal assistance on Title 24, part 6

The state first implemented its Building Energy Efficiency Standards in 1978. The standards are updated approximately every three years. According to the California Energy Commission, buildings that meet the 2013 standards will use 25% less energy for lighting, heating, cooling, ventilation, and water heating than those built to the 2008 standards.

California has a goal to make all new homes Zero Net Energy (ZNE) by 2020 and all new commercial buildings ZNE by 2030. A ZNE building uses a combination of energy efficiency and distributed renewable energy to meet 100 of its annual energy needs. Given the three year code cycle, only two versions of Title 24, Part 6 remain before ZNE will required by the code.
