Title 24 Requirements

New Title 24 requirements will go into effect on January 1, 2010. These new requirements for roofing products deal with the “Heat Island Effect” caused by the suns energy reflecting off structures and contributing to global warming. Structures will be required to use products that meet Reflectance, Emissivity and SRI values as set by the new standards.

US Tile makes compliance with then new Title 24 requirements easy. All US Tile products and colors are Title 24 compliant.


Background

The California Energy Commission was initially developed in 1974 and signed by the legislature during Gov. Reagan’s Tenure which created the CEC

• Gov. Brown started funding the commission in 1975

• The California Energy Commission staff through committee’s writes Triennial Standards Updates with its utility partners

• Updates presented to public with feedback given

• Comments processed into standards

Title 24 Changes for 2010

• Non-Residential Compliance Manual 939 pages

• Residential Compliance Manual 521 pages

• Massive overhaul and upgrade on both

• Commercial changes for coatings effective Sept 11, 2006

• First Initial changes for standards in Residential Cool Roofs

• New standards were set for August 1, 2009

• More training was needed pushed back to January 1, 2010

• Bigger upgrade for 2011 expected possibly 20% increase in standards

CEC Plans for Compliance

• Building Standards are enforced by local building officials

• Enforcement may involve third party verifications by a HERS Rater for particular measures such as duct sealing and TXV’s.

• Compliance Methods: Buildings must comply with mandatory measures and with either the prescriptive or performance compliance approaches, essentially an energy budget for each building referenced to one of 16 specific climate zones.

• Mandatory Measures: All buildings must comply with mandatory measures regardless of the compliance path.

• Prescriptive Compliance: Compliance through prescriptive packages which varies with climate zones – no tradeoffs are allowed.

• Performance Compliance: Use an approved compliance software to demonstrate compliance for the entire building – allows tradeoffs.

• Compliance Options: Measures that are not required prescriptively but can result in a compliance credit if installed, such as high EER air conditioning and buried ducts.

CEC Policy Goals

   Energy Action Plan / IEPR

• Efficiency at the top of the Loaded Order

• Demand Response

• Encourage PVs in standards

• Combine energy and water efficiency

   West Coast Governor’s Global Warming Initiative

• 15% efficiency savings through State Building Codes by 2015

 
   Green Building Initiative

• 20% increase in non-residential standards by 2015

 
   Climate Action Initiative

• Standards must help to meet greenhouse gas emissions reduction goals
