Updating the 2013 Title 24 Building Efficiency Codes

8,543 views

Published on

The upcoming 2013 Title-24 Building Efficiency Standards were approved by the California Energy Commission on May 9, 2012. The new Title-24 energy code incorporates significant changes that will affect architects, builders, contractors, energy consultants, and solar PV installers. This class will review the upcoming changes to the energy code and the impact on building design along with compliance strategies that will allow you to comply with the new, stricter energy code cost effectively.

Mark Madison is a Certified Energy Plans Examiner, Certified Energy Analyst, HERS rater, and serves on the board of directors of the California Association of Building Energy Analysts (CABEC).

  61. 61. HVAC Minimum AFUE, SEER, EER SEER vs EER EER is measured at 80 degrees indoor air running continuously SEER is measured by using the EER and factoring in the same unit running under a lighter load (80 degrees indoor, 82 degrees outdoor and cycling on and offwww.energycode.com www.energycode.com
  62. 62. HVAC Minimum AFUE, SEER, EER SEER vs EER Why this matters: Possible for two units with the same SEER to have different EERs For two units with a given SEER the one with the higher EER will be more efficient EER’s higher than 12 require HERS verification Take time to verify SEER and EERwww.energycode.com www.energycode.com
  63. 63. HVAC Minimum AFUE, SEER, EER SEER vs EER Why this matters: EER higher than 12 will trigger a HERS credit in the Title-24 compliance calculations Will also appear on the CF-1R as a HERS measure required verification and a CF-4Rwww.energycode.com www.energycode.com
  64. 64. HVAC Minimum AFUE, SEER, EER SEER vs EER 2008 Standards 2013 Standards AFUE: 78% AFUE: 80% SEER: 13.00 SEER: 14.00 EER: 10.00 EER: 12.00 Duct Insulation R:4.2 R-6 (Climate zones 6-8) R-8 (All other climate zones)www.energycode.com www.energycode.com
  65. 65. HVAC Minimum AFUE, SEER, EER SEER vs EER Bottom Line: Minimum efficiency levels remained essentially unchanged from 2005 to 2008 standards.
