What We Need From You For Your Title 24 Energy Calculation

With every Title 24 Energy Calculation, we perform, specific architectural and building plan data will be required. This information can be submitted through our online client portal, preferably in PDF format. We use the exact information from your plans, so we must have the most up to date version available.

What To Expect With Your Title 24 Energy Calculation

Below is a rough outline of what to expect with your Title 24 Energy Calculation. We do our best to make the process as convenient and quickly as possible. 

Out Title 24 Energy Calculation Process

The Energy Calculation Process is simple. We collect the information we need from your construction or architect plans, import the data into our software, and email your final report. If your initial plans do not meet California regulation we will assist you with design alternatives. The software allows the creation of different combinations of equipment and building materials to determine the most cost-effective path to energy compliance. 


In instances when your building plans do not pass the initial Title 24 Energy Calculation, we are here to assist. With our CEC approved software, we are able to modify your plans to meet regulation. We will create the most cost effective solution by trading out building materials or energy systems from your original plan. 


Generally speaking, any project that requires a permit will also require Title 24 calculations. This includes all new construction and any residential project that modifies the existing envelope (walls, floors, roofs, windows, etc), or adds or modifies mechanical equipment (HVAC and Water Heater). Also, any project that converts unconditioned space to conditioned space (i.e. a garage to living room conversion) will require a Title 24 Verification. If you have any specific questions about your project and if a Title 24 report is required, give us a call or fill out our online form today.
