NR = No requirement.
a. R- values are minimums. U- factors and SHGC are maximums. R -19 shall be permitted
to be compressed into a 2 x 6 cavity.
b. The fenestration U- factor column excludes skylights. The SHGC column applies to all
glazed fenestration.
c. The first R -value applies to continuous insulation, the second to framing cavity
insulation; either insulation meets the requirement.
d. R -5 shall be added to the required slab edge R- values for heated slabs.
e. There are no SHGC requirements in the Marine zone.
f. Or insulation sufficient to fill the framing cavity, R -19 minimum.
g. "13 +5" means R -13 cavity insulation plus R -5 insulated sheathing. If structural
sheathing covers 25 percent or less of the exterior, insulating sheathing is not required
where structural sheathing is used. If structural sheathing covers more than 25 percent of
exterior, structural sheathing shall be supplemented with insulated sheathing of at least R-
2.
h. The ceiling insulation alternative in Section 402.1.1.1 can be used as an equivalent
alternative for R -30."
SECTION 4. Ordinance No. 09 -48, as amended, is further amended by amending
paragraph (6) of item (6) of Section 3 to read as follows:
"6. For compliance with Subsection 1.4, a cool roof shall have an infrared
[eice] emissivity of no [mere] less than 0.75 when tested in accordance with
ASTM E -408 and a high solar reflectance. Alternatively, the corresponding Solar
Radiance Index (SRI) for a cool roof can be used. The manufacturer's test results
shall be acceptable for compliance. A cool roof has both a light color (high solar
reflectance) and a high [emittance] emissivity (can reject heat back to the
environment). White painted surfaces and other smooth white coatings typically
meet these requirements. Surfaces that do not meet the requirements include
unpainted metal and metalized roof coatings (silver appearance)."
SECTION 5. Ordinance No. 09 -48, as amended, is further amended by amending item

and on heaters and pumps according to a preset schedule shall be installed

2. Where pumps are required to operate solar- and waste -heat-
recovery pool heating systems.
403.7.3 Pool covers. Heated pools shall be equipped with a vapor
retardant pool cover on or at the water surface. Pools heated to more than
90 ° F (32 ° C) shall have a pool cover with a minimum insulation value of R-
12.
Exception: Pools deriving over 60 percent of the energy for heating
from site - recovered energy or solar energy source. '
