NEW CONSTRUCTION MODEL REACH CODE, ALL -ELECTRIC VERSION 1.0

What’s New
• This model reach code ordinance, which is based on the Electric-Preferred Model Ordinance, includes all-electric requirements for the most common occupancies and adds specific requirements for mid-rise residential new construction.

Scope
• All new residential buildings and all new hotels, motels, office buildings and retail buildings must be all-electric, with exceptions for ADUs and hospitals. Jurisdictions may modify the occupancies subject to the all-electric requirements. o The All-Electric requirements of this scope were found to be cost-effective in all climate zones except for:
 High-rise (including Mid-rise) residential buildings in Climate Zones 1 and 16; and
 Office buildings and hotels in Climate Zone 16.
• All other new mixed-fuel buildings must comply with stricter performance or prescriptive requirements.
• All new buildings must install a PV system as a mandatory measure.

Summary of Requirements by Occupancy
Occupancy All-Electric Solar PV Energy Efficiency
Low-Rise Residential Yes No (required under
State Code) No
High-Rise Residential (includes
Mid-Rise) Yes Yes No
Hotels, Motels, Office and
Retail Yes Yes No
Other Nonresidential No Yes Required for
Mixed-Fuel

NEW CONSTRUCTION MODEL REACH CODE, ALL -ELECTRIC VERSION 1.0 Instructions
• This is one of three versions. The Electric-Preferred version requires higher efficiency for mixed-fuel buildings. The Fuel-Neutral version requires higher efficiency for all buildings.

The All-Electric version requires all-electric for the most common occupancies and higher efficiency for other mixed-fuel buildings. All versions require solar PV. The latest version of this document and supporting materials are available at LocalEnergyCodes.com. • The performance values and prescriptive measures are based on results from cost effectiveness studies. Jurisdictions may choose a more tailored approach based on the studies, for example, modifying the ordinance to require higher energy performance from all-electric buildings. The Codes and Standards Reach Codes team is available to assist jurisdictions with this process.
• Jurisdictions may also wish to modify elements of the ordinance, such as those marked with the text “[Option]”. For example:
o Adding the electric-readiness supplement for nonresidential and/or residential buildings (requires mixed-fuel buildings to install infrastructure to facilitate future conversion to electric equipment);
o Specifying occupancies subject to the all-electric requirements; o Modifying exception for Accessory Dwelling Units (ADUs) • When modifying the language, ensure all Standards references are maintained and the ordinance still meets the CEC requirements. Also, edit the Purpose section to reflect the changes.
• Prescriptive requirements vary by climate zone and are a complete package of measures that achieve similar efficiency levels as the performance requirements. Those requirements that are not applicable to the climate zone must be deleted and subsequent paragraphs renumbered.
• The model language is intentionally detailed. Jurisdictions may wish to pare it down and leave more discretion to the building administrator. Some of the details could be moved to guidance documents.
• Sample findings are presented as Whereas clauses; alternatively, they may be incorporated as express findings in the ordinance, referenced as an attachment or passed as a separate resolution based on local practice.
• Local authorities for some of the proposed requirements are untested. For example, the electric readiness provisions in the supplement are proposed without a cost-effectiveness analysis on the advice of CEC staff that they are not, in themselves, energy performance requirements.
• The headings, footnotes and instructions (in blue) are for staff reference and should be removed in the final ordinance.
• The draft ordinance text, sample findings and CEQA determination language are provided as examples only. Ensure all ordinance materials are reviewed and verified by relevant jurisdiction staff and the city/county attorney.

Performance Requirements
If low-rise residential buildings are not required to be all-electric, consider adding the performance and prescriptive requirements from the Electric-Preferred Version of model ordinance.

Section 140.1 is modified as follows:

SECTION 140.1 – PERFORMANCE APPROACH: ENERGY BUDGETS
An addition or alteration to an existing building or a newly constructed All-Electric Building complies with the performance approach if the energy budget calculated for the Proposed Design Building under Subsection (b) is no greater than the energy budget calculated for the Standard Design Building under Subsection (a).

A newly constructed Mixed-Fuel Building complies with the performance approach if the energy budget calculated for the Proposed Design Building under Subsection (b) has a compliance margin, relative to the energy budget calculated for the Standard Design Building under Subsection (a), of at least 5%. [Verify/modify compliance margins by climate zone.]3

(a) Energy Budget for the Standard Design Building. The energy budget for the Standard Design Building is determined by applying the mandatory and prescriptive requirements to the Proposed Design Building. The energy budget is the sum of the TDV energy for space-conditioning, indoor lighting, mechanical ventilation, service water heating, and covered process loads.

(b) Energy Budget for the Proposed Design Building. The energy budget for a Proposed Design Building is determined by calculating the TDV energy for the Proposed Design Building. The energy budget is the sum of the TDV energy for space-conditioning, indoor lighting, mechanical ventilation and service water heating and covered process loads.

(c) Calculation of Energy Budget. The TDV energy for both the Standard Design Building and the Proposed Design Building shall be computed by Compliance Software certified for this use by the Commission. The processes for Compliance Software approval by the Commission are documented in the ACM Approval Manual.
