ENERGY DESIGN RATING
Energy Design Rating (EDR) is an alternate way to express the energy performance of a building using a scoring system where 100 represents the energy performance of the Residential
Energy Services (RESNET) reference home characterization of the 2006 International Energy Conservation Code (IECC) with California modeling assumptions. A score of zero represents
the energy performance of a building that combines high levels of energy efficiency with renewable generation to"zero out' its TDV energy. Because EDR includes consideration of
components not regulated by Title 24, Part 6 (such as domestic appliances and consumer electronics), it is not used to show compliance with Part 6 but may instead be used by local
jurisdictions pursuing local ordinances under Title 24, Part 11 (CALGreen).
As a Standard Design building under the 2016 Building Energy Efficiency Standards is significantly more efficient than the baseline EDR building, the EDR of the Standard Design building
is provided for Information. Similarly, the EDR score of the Proposed Design is provided separately from the EDR value of installed PV so that the effects of efficiency and renewable
energy can both be seen

2016 Low -Rise Residential Mandatory Measures Summary
NOTE: Low-rise residential buildings subject to the Energy Standards must comply with all applicable mandatory measures, regardless of the compliance approach
used. Review the respective section for more information. 'Exceptions may apply.
fnrininal 0R190161
Building Envelope Measures:
§ 110.6(a)l:
Air Leakage. Manufactured fenestration, exterior doors, and exterior pet doors must limit air leakage to 0.3 cfmlftz or less when tested per
NFRC-400 or ASTM E283 or AAMA/WDMA/CSA 101/I.S.2/A440-2011.'
§ 110.6(a)5:
Labeling. Fenestration products must have a label meeting the requirements of § 10-111(a).
Field fabricated exterior doors and fenestration products must use U-factors and solar heat gain coefficient (SHGC) values from TABLES
§ 110.6(b):
110.6-A and 110.6-13 for compliance and must be caulked and/or weatherstri ed.'
Air Leakage. All joints, penetrations, and other openings in the building envelope that are potential sources of air leakage must be caulked,
§ 110.7:
asketed,orweather stripped.
§ 110.8(a):
Insulation Certification by Manufacturers. Insulation specified or installed must meet Standards for Insulating Material.
§ 110.8(g):
Insulation Requirements for Heated Slab Floors. Heated slab floors must be insulated per the requirements of § 110.8(g).
§ 110.8(i):
Roofing Products Solar Reflectance and Thermal Emittance. The thermal emittance and aged solar reflectance values of the roofing
material must meet the requirements of § 110.8 i when the installation of a cool roof is specified on the CF1 R.
§ 110.80):
