2 Course Goal Brief overview of MAJOR CHANGES in 2013 Title 24, Part 6 for Residential HVAC (new construction, additions and alterations). 2

3 Changes in Scope and Application Welcome Changes in Scope and Application When, Where and Why? TDV Changes New Software and HERS Registration Procedures HVAC: New Construction HVAC: Additions and Alterations HVAC: Forms Wrap Up 3

4 When, Where.. When (current schedule): Any projects that apply for permit on or after January 1, 2014 will be subject to the 2013 Standards. Exception: Nonresidential Registry January 1, 2015 Where can you find? Marked version of the 2013 Standards, ACM, 2 nd draft version of the Residential Manual and compliance forms. 4

5 and Why? 2013 Res HVAC Standards Overview for WHPA 2020 All California new residential construction zero net energy Low-income homes energy efficient 5

New Software and HERS Registration Procedures Performance (CF-1R-PRF-01) New simulation engine CSE (California Simulation Engine) Compliance Manager software from CEC to provide Standard/Proposed

7 New Software and HERS Registration Procedures Performance (CF-1R-PRF-01) New simulation engine CSE (California Simulation Engine) Compliance Manager software from CEC to provide Standard/Proposed rules for modeling All software vendors will use same plug in to Compliance Manager software Creation of CF-1R will require internet access to CEC s Compliance Manager. HERS registration process will include uploading the CF-1R from the CEC for registration and signatures per current procedures. This form is an example of CF-1R-PRF-01. Actual form still under construction. 7

8 New HERS Registration Procedures Prescriptive New Buildings (CF-1R-NCB-01) HERS registration process will include uploading the CF-1R from the CEC for registration and signatures per current procedures. 8

New HERS Registration Procedures Prescriptive HVAC Alterations HERS registration process will include uploading the CF-1R from the CEC for registration and signatures per current

9 New HERS Registration Procedures Prescriptive HVAC Alterations HERS registration process will include uploading the CF-1R from the CEC for registration and signatures per current procedures. CF-1R-PRSC-ALT-02 for CZ 1, 3, 4-7 and 16: Duct Leakage Airflow and Fan Watt Draw CF-1R-PRSC-ALT-03 for CZ 2 and 8-15: Duct leakage Airflow and Fan Watt Draw Refrigerant Charge 9

15 HVAC: Additions and Alterations Welcome Changes in Scope and Application HVAC: New construction HVAC: Additions and Alterations Heating and Cooling Equipment IAQ Ventilation Ducts HERS HVAC: Forms Wrap Up 15

16 HVAC: Additions and Alterations HVAC Equipment IAQ Ventilation If existing system extended, equipment need not comply with Part 6. Heating capacity must be adequate to meet CBC Section If refrigerant-containing system components altered, setback thermostat required. Addition less than 1,000 sf or less are exempt from whole-building airflow requirements, all other applicable requirements still apply Greater than 1,000 sf, all apply Ducts Ducts extended from existing system that are less than 40 linear feet: R-6 duct insulation. Over 40 linear feet, new AND existing ducts must meet mandatory and prescriptive requirements. HERS New equipment (not a repair) must meet all applicable measures as for new construction, including all HERS measures. Existing and new ducts of new/altered system to be HERS tested and verified. 16

17 HVAC: Alterations Using Performance Method To take performance credit for improving a feature of existing (prealtered) condition, the feature must be verified by a HERS rater before construction and permit submittal. Otherwise, the appropriate prescriptive or mandatory efficiency level for that measure is used to set the standard design in the compliance software (b)1D For further details, see the 2013 Residential ACM Reference Manual. 17
