What are the key changes in Title 24 for 2022 regarding building envelopes?
In 2022, Title 24 introduces new mandatory requirements for all projects exceeding 700 sqft. This includes specific focus areas such as Roof Deck, Ceilings, and Rafter Roofs. However, there are exceptions, notably for Ducts in Conditioned Space (DCS) and supply ducts less than 12 feet in unconditioned space.

Are there additional insulation requirements for certain climate zones?
Yes, additional insulation requirements apply to Climate Zones 1-4 and 8-16, ensuring that buildings in these zones meet enhanced energy efficiency standards.

What are the prescriptive requirements for reroofing (addition/alteration) projects?
Title 24 introduces prescriptive requirements for reroofing projects, particularly addressing low-sloped roof insulation requirements for Climate Zones 1, 2, 4, and 8-16. Exceptions apply.

What are the new mandatory requirements for kitchen range hood airflow in mechanical systems?
The 2022 updates include mandatory requirements for kitchen range hood airflow in both new construction and addition/alteration projects, ensuring proper ventilation standards are met.

Are there any changes to central air conditioners and heat pumps efficiency standards?
Yes, the Department of Energy (DOE) minimum efficiencies for central air conditioners and heat pumps are now part of the Title 24 requirements for enhanced energy performance.

What upgrades are mandated for duct sealing, and what are the associated HERS requirements?
Title 24 includes new requirements for duct sealing upgrades, coupled with Home Energy Rating System (HERS) requirements to enhance overall energy efficiency.

What are the new requirements for ducts and duct replacement?
The 2022 updates introduce specific requirements for new ducts and duct replacement, ensuring that these components meet the latest energy efficiency standards.

Are there heat pump prescriptive requirements for specific climate zones?
Yes, heat pump prescriptive requirements apply to new construction projects in Climate Zones 3, 4, 13, and 14.

What are the prescriptive and performance requirements for domestic water heating in new construction?
Title 24 outlines both prescriptive and performance requirements for domestic water heating in new construction projects, contributing to enhanced energy efficiency.

What are the exceptions and requirements for PV and battery storage systems?
Title 24 includes a 1.8kW exception to PV prescriptive requirements, along with specific mandates for single-family requirements and new home energy storage system readiness.

What is the New Home Electrification Ready Requirement?
This requirement mandates that new homes be designed to accommodate future electrification, aligning with the broader push towards sustainable and electrified energy sources.

Why is HERS testing required?
HERS (Home Energy Rating System) testing is required to ensure that homes and buildings meet California’s energy efficiency standards under Title 24. It helps verify that HVAC systems, ductwork, insulation, and overall energy performance comply with state regulations. The goal is to reduce energy consumption, lower utility costs, improve indoor air quality, and enhance overall comfort for homeowners and building occupants.

How long does the test take?
The duration of a HERS test depends on the type of inspection being performed. A basic duct leakage or airflow test typically takes about 1 to 2 hours, while a more comprehensive Home Energy Audit may take several hours depending on the size and complexity of the building. Our team works efficiently to ensure minimal disruption while delivering accurate results.

What happens if my system fails?
If your system fails a HERS test, don’t worry! We will provide a detailed report outlining the issues and recommend corrective actions. You may need to repair or upgrade specific components, such as sealing duct leaks, improving airflow, or adjusting refrigerant levels. Once the necessary fixes are made, we can schedule a retest to ensure compliance. We also offer exemption assistance and guidance to help you navigate the process smoothly.
