Tech Tip: HERS Measures New construction projects face several challenges in meeting the new 2008 Title 24 Standards. In most cases, energy consultants will need to integrate HERS measures into the Title 24 report. However, the implications of these measures are often overlooked. When selecting HERS measures, keep the following tips in mind: 1. Coordination with your design team members and subcontractors is critical when determining which HERS measures to install to ensure that everyone can prepare and schedule accordingly. For example, if the Quality Insulation Installation (QII) HERS measure is being used, the HERS rater needs to inspect the insulation before the drywall goes up, which requires coordination with the drywall contractor. If the HERS rater cannot verify the insulation installation, it may fail to comply with the program and not receive incentives. 2. Be aware of potential additional costs involved when choosing HERS measures. For example, using the Low Leakage Ducts in Conditioned Space HERS measure could require redesigning the HVAC equipment placement, thus increasing design and construction costs. 3. Recognize that some measures could affect your construction schedule. For example, using the Blower Door HERS measure requires the plumber, HVAC contractor, door and window installer to seal their individual components tightly to ensure no leakage. This process takes time. If the HERS rater finds more leakage than Title 24 allows or the test fails, then the HERS rater is required to re-test, further lengthening the verification process. For additional details about HERS measure requirements, please refer to the 2008 Residential Compliance Manual or contact CMFNH staff.
