CHULA VISTA MUNICIPAL CODE, ADDING SECTION
15.12.030, COOL ROOF
WHEREAS, on May 3, 2011, City Council approved Resolution 2011-076 in which City
Council adopted the Climate Adaptation Plans and approved their implementation; and
WHEREAS, the adopted Climate Adaptation Strategies will help reduce the City's future
risks and costs from expected local climate change impacts; and
WHEREAS, the Implementation Plan for Strategy #3, Cool Roofs, proposed amending the
City's Green Building Standards, Chula Vista Municipal Code (CVMC) Chapter 15.12, to
require what are currently voluntary cool roof measures in the 2010 California Green Building
Standazds Code on new low-rise residential developments; and
WHEREAS, the California Energy Commission determined that because cool roofing is
currently one of the compliance options available in the California Energy Code and because it
affects the energy efficiency of buildings, mandating cool roofs requires the California Energy
Commission's review and approval prior to a cool roof ordinance taking effect; and
WHEREAS, the California Energy Commission's review and approval process requires City
Council's determination that the proposed local standards will not require buildings to consume
more energy than permitted by the current California Energy Code and are cost-effective; and
WHEREAS, a study prepazed by Gabel Associates, LLC analyzed the energy savings and
cost-effectiveness of requiring Tier 1 and Tier 2 residential cool roof standards, which are
currently voluntary standazds in the 2010 California Green Building Standazds Code, in the two
Climate Zones that are within the boundary of Chula Vista; and
WHEREAS, the results of the study showed that requiring Tier 1 or Tier 2 cool roof
standazds in Climate Zone 7 is not cost-effective, however the requirements are cost-effective in
Climate Zone ] 0; and
WHEREAS, based on the results of the study, Gable Associates, LLC recommends requiring
Tier 1 or Tier 2 standards only in Climate Zone10; and
WHEREAS, based on the results of the study, Tier 2 cool roof standards in Climate Zone ] 0
are more cost-effective than Tier 1 standards; and
WHEREAS, based on staff reseazch, the majority of new residential developments in Chula
Vista will have steep-sloped roofs with concrete or clay the roofing that will meet or exceed Tier
1 cool roof standards; and
