Title 24 Energy Code Standards are MANDATED for every residential project built, making a minimum energy efficient code all buildings must abide to, in order to get a final permit. You are hearing more about the energy code because: it becomes more stringent every three years, third party testers are now required to ensure compliance is met, and building inspectors are enforcing it. About every three years, the energy code standards change in an effort to get every new building to eventually become net zero (building produces as much energy as it uses making the building self-sustainable) or as close as possible. The government’s goal is that all new residential buildings will be net zero ready in 2020 and all new commercial buildings in 2030. This is also why some products you installed in one development a year ago, may not qualify to be installed in next year’s project. Every building and every project are different, the code allows for some items to have a tradeoff in order to meet compliance, different climate zones dictate and prompt different energy efficient compliance minimums, and building orientation all could have an effect on a project’s energy calculations.
2016 Energy Standard Code will officially go in to effect for projects permitted on or after January 1, 2017.
