Title 24 Calculations & Compliance
The California Energy Code (C.E.C.) is a set of regulatory mandates and defined industry standards within the broader building code (often referred to simply as, “Title 24” – a shortening of its overall placement within the California Code of Regulations). These standards include Mandatory Requirements, Performance Standards, and Prescriptive Standards, each of which undergo significant changes in technical detail as the law adapts to industry developments.
Title 24 standards & requirements are updated regularly to allow the provision to account for the latest developments in energy-efficient technologies & methods. In our rapidly changing energy landscape, this has resulted in a constantly-shifting criteria, which less regionally-focused companies often find difficulty adapting to. Title 24 includes highly localized provisions which require a depth of regional knowledge & expertise – for example, “climate zones” which alter requirements based on location within the state.
New Energy-Efficiency Standards for 2019
Updated for 2019, the California Energy Code’s “Building Energy Efficiency Standards” include revised provisions that will reduce single-family home energy use by 7% compared to the previous 2016 regulations. When including rooftop solar power generation, the overall energy-use reduction is well over 50% compared to 2016 standards. Under the new 2019 regulations, all new homes in California will require solar photovoltaic systems.
The California Energy Commission estimates that these energy-efficiency standards will increase the cost of new home construction by $9,500 for an average single-family residence. However, the Energy Commission also estimates approximately $19,000 in cost-savings from energy and maintenance cost over a traditional 30-year mortgage. When calculated monthly, the new regulations will cost an additional $40 per month, but save $80 per month on heating, cooling, and lighting bills, over the same 30-year timeframe.
