Los Angeles Municipal Code § 4.201 Appendix A4 Residential Voluntary Measures

requirements of the California Building Energy X X2 X2 Efficiency Standards.3

Performance Approach for Newly Constructed Buildings

A4.203.1.1 Hourly Source Energy Rating (EDR1). EDR1 ratings for building design shall be computed by Energy Compliant software and shall X2 X2 reduce the EDR1 required by the software by the compliance margins specified in Table A4.203.1.1.

A4.203.1.2 Prerequisite options. In addition, a minimum of two of the efficiency measures specified in Sections A4.203.1.2.1 through A4.203.1.2.8 will be required to be met. • Roof deck insulation or ducts in conditioned space. • High-performance walls. • Compact hot water distribution system. X2 X2 • Drain water heat recovery.

• High performance vertical fenestration.

• Heat pump water heater demand management. • Battery storage system controls.

• Heat pump space and water heating.

A4.203.1.3 Consultation with local electric service provider. Local jurisdictions considering adoption of reduced EDR targets based on using solar photovoltaic (PV) systems larger than required by the California Energy Code shall consult with the X2 local electric service provider to ensure that that PV system sizing required to comply with the EDR targets will be acceptable to the local electric service provider.

Performance Approach for Additions

A4.204.1.1 Tier 1. If only one mechanical system is added or modified, the Energy Budget is no greater than 95% of the Title 24, Part 6, Energy Budget for the Standard Design Building. If two or X2more mechanical systems are added or modified, the Energy Budget is no greater than 90% of the Title 24, Part 6, Energy Budget for the Standard Design Building.

A4.204.1.2 Tier 2. If only one mechanical system is added or modified, the Energy Budget is no greater than 90% of the Title 24, Part 6, Energy Budget for the Standard Design Building. If two or X2more mechanical systems are added or modified, the Energy Budget is no greater than 85% of the Title 24, Part 6, Energy Budget for the Standard Design Building.
