Arzel Zoning
Panic and mayhem seem to be raining down on the HVAC streets of California as contractors scramble to interpret the new regulations and changes to bypass systems with the passing of the 2013 version Title 24.
Title 24 is the building and energy code standard in California, which ensures building construction, as well as system design and installation, reach at least a minimum level of energy efficiency and maintains environmental quality.
These standards result in lower energy costs, greater comfort, more dependable system service, and a better environment.
Yes, these changes do only apply to California currently, but the HVAC trends in the west coast state seem to set the standard for the industry. So what do we need to know about Title 24?
The CEC (California Energy Commission) has approved certain compliance software packages to help design and submit systems with bypass dampers. Depending on the system, you can choose the Performance Compliance Method or the Prescriptive Method.
There may be different airflow requirements when zoning systems are used versus systems without zoning.
California’s Title 24 building codes include construction and design factors such as energy efficiency, lighting, ventilation and more. Any external or mechanical changes that rely on energy usage related to Title 24. These rules apply to new construction and existing buildings for residential, non-residential and businesses.
The standards are updated every three years, with the last set written in 2022 and enacted in January 2023. The next set is anticipated in 2025.
Types of buildings subject to these codes include:
Yes, energy budgets do vary by climate zone and building type. There are 16 climate zones designated in the state of California. The energy code is tailored to local conditions, providing some flexibility in the energy efficiency buildings can achieve.
