This CASE Report will look at various aspects of how additions and alterations are currently handled by the Title 24, Part 6 Standards. The goal is to, where appropriate, identify unrealized energy savings opportunities, as well as streamline the process to achieve greater code compliance in additions and alterations. The CASE Report will include three submeasures.
Investigate the prescriptive requirements and exceptions
This submeasure will identify opportunities for efficiency improvements by expanding existing requirements where appropriate. The following will be considered, among other ideas.
- Re-evaluate threshold triggers for various prescriptive requirements (i.e. addition square feet, length of ductwork extension, etc.).
- Increase ceiling insulation levels for additions and alterations 700 square feet or less.
- Evaluate expanding the cool roof requirements for roof replacements.
Consider improvements to standards language on additions and alterations
This submeasure will improve readability and identify opportunities where the process could be streamlined to encourage code compliance, especially for projects with limited scope such as equipment replacements or changeouts.
Evaluation of Alternative Calculation Method Software
This submeasure will include testing of CBECC-Res 2019 to validate that the 2019 Building Energy Efficiency Standards Alternative Calculation Method Reference Manual are properly implemented in the software for performance evaluations of additions and alterations.
