Title 24 Energy Calculations in California
The threat of climate change has led to more stringent building codes and energy regulations in the United States. In California, all new construction and major renovations are subject to the energy efficiency standards set forth in Title 24, Part 6 of the California Building Standards Code. These standards, updated every three years, aim to reduce the state’s greenhouse gas emissions by making buildings more energy-efficient.
Compliance with the Title 24 California standards is required in order to obtain a Certificate of Occupancy. 5 Star Energy is the leading provider of Title 24 energy calculations in California.
What Are Title 24 Energy Calculations?
A Title 24 energy calculation is a form of energy auditing service that assesses a building’s compliance with the energy efficiency standards set forth in Title 24, Part 6. The calculation includes an analysis of a building’s mechanical, electrical, and plumbing systems, as well as its envelope.
The goal is to ensure that the building meets or exceeds the minimum energy performance standards required by law. This involves evaluating:
- Insulation levels — walls, ceilings, floors, and attic spaces
- Window specifications — U-factor, SHGC (Solar Heat Gain Coefficient)
- HVAC system efficiency — equipment sizing, duct design, refrigerant charge
- Lighting design — residential and commercial lighting power density
- Water heating systems — type, efficiency rating, solar-ready requirements
- Building envelope — air sealing, thermal bridging, continuous insulation
