to each locality.
Applicable to a variety of buildings: Can be used for residential detached single or two
family buildings and multifamily buildings.
What is a COMcheck?
COMcheck is a tool which ensures that commercial projects comply with energy codes and standards, such as those
set by ASHRAE or the International Energy Conservation Code (IECC). It generates compliance reports that can be
submitted for regulatory approval.
Key Features of COMcheck
HVAC and Lighting Calculations: Helps users determine if a building meets energy code
requirements and helps in lighting calculations.
Supports Multiple Codes: Supports state specific codes such as 2023 Florida energy code,
California energy code 2022, Chicago energy code, etc.
Data Entry Wizards: Allows wizards for inputting data on lighting, envelope, HVAC, etc.
Compliance Reports: Generates reports on Envelope Compliance, Interior and Exterior
Lighting Compliance, Mechanical Compliance and Plan Review Checklist.
Ensure your building meets energy compliance standards with ease. Our experts provide accurate and efficient
REScheck and COMcheck services to streamline your project's approval process.
Refers to the calculation process used to determine the heating and cooling loads to ensure your HVAC system is
neither too large nor too small — ensuring accurate electric load calculation of buildings.
Manual S
Determines the equipment and materials needed for the HVAC system, considering factors like size, efficiency
and capacity of the building.
Manual D
Refers to the duct sizing to distribute heated or cooled air throughout the space ensuring that air is
distributed evenly, minimizing hot or cold spots and ensuring consistent comfort.

California's Building Standards Code – Energy Compliance
What is CA Title 24?
Title 24 refers to California's Building Standards Code, designed to promote energy efficiency and
environmental sustainability in both new and existing construction projects. Title 24 calculations work by
reducing energy consumption and improving environmental sustainability by including building envelopes, water
heating, lighting, electrical and HVAC systems.
Why Title 24 is Important
Reduces Energy Consumption: Helps buildings use less energy and emit less greenhouse gas.
It is one of the key parts of California's strategy to combat climate change.
Ensure Occupant Comfort: Promotes comfort by providing better temperature regulation, air
quality and natural lighting.
Lower Utility Bills: Helps homeowners and businesses save money by promoting
energy-efficient designs.
Improve Environmental Sustainability: Makes sure the buildings are more resource-efficient
and less polluting.
How Title 24 Affects Your Construction Project
For Building Permits: Title 24 calculations must be concluded in detail and submitted to
local authorities for inspection to receive building permits.
Energy Calculations: Title 24 mandates the use of energy-efficient technologies and
practices, including lighting, HVAC equipment and insulation.
Green Building Requirements: If your project involves new construction or major
renovations, Title 24 certification is required to meet green building standards outlined in CALGreen.
Cost Considerations: While initial construction costs may increase, they ultimately result
in long-term savings on energy bills and maintenance costs.
Ready to verify your project meets Title 24 standards? Contact us today to learn how we can help you navigate the
latest energy efficiency requirements.
