Sec. 8100.1 Definitions.

"Energy Budget" is the maximum amount of time dependent valuation (TDV) energy that a proposed building, or portion of a building, can be designed to consume, calculated with the approved procedures specified in Part 6 of Title 24 of the California Code of Regulations. The Energy Budget is calculated based upon the features in the Standard Design Building.

"Low-Rise Residential Building" is a building, other than a hotel/motel, that is occupancy group:

R-2, multifamily, with three (3) stories or less; or

R-3, single-family; or

U-building, located on a residential site.

"R-2 Residential Occupancies" as defined in 2016 California Building Code, Title 24, Part 2, Volume 1, Section 310.4, Residential Group R-2.

"R-3 Residential Occupancies" as defined in 2016 California Building Code, Title 24, Part 2, Volume 1, Section 310.5, Residential Group R-3.

"Single-Family Building" is a single dwelling unit of occupancy group R-3, as defined in the CBC, which stands separate and unattached from other dwelling units but may have an attached garage.

"Standard Design Building" is a building that complies with the mandatory and prescriptive requirements in Title 24, Part 6 of the California Code of Regulations (California Energy Code) by using the building energy modeling rules described in the Alternative Calculation Method (ACM) Reference Manual. (Ord. 1507, eff. 10/19/2018)

Sec. 8100.2 Purpose and Intent.

It is the purpose and intent of this Section to provide standards for builders and developers of newly constructed Low-Rise Residential Buildings to design and construct the buildings to exceed minimum 2016 Title 24, Part 6 of the California Code of Regulations requirements to achieve energy savings, reduce greenhouse gas emissions and the environmental footprint of new developments. (Ord. 1507, eff. 10/19/2018)

Sec. 8100.3 Requirement.

A. Single-Family Buildings. Newly constructed buildings of no more than two (2) dwelling units in Arcata shall:

1. Be designed and constructed to include the green building measures specified as mandatory under the California Green Building Standards Code (CALGreen); and

2. Meet the efficiency requirements of Section A4.203.1.2 Performance Standard of the CALGreen Code and shall have an Energy Budget that is no greater than seventy percent (70%) of the Energy Budget for the Standard Design using efficiency measures only or a combination of efficiency measures and the photovoltaic (PV) system compliance credit.

B. Multifamily Buildings. Newly constructed multifamily residential buildings of occupancy group R-2 in Arcata shall:

1. Be designed and constructed to include the green building measures specified as mandatory under the California Green Building Standards Code (CALGreen); and

2. Meet the efficiency requirements of Section A4.203.1.2 Performance Standard of the CALGreen Code and shall have an Energy Budget that is no greater than eighty percent (80%) of the Energy Budget for the Standard Design using efficiency measures only or a combination of efficiency measures and the photovoltaic (PV) system compliance credit.

C. PV Compliance Credit. The PV compliance credit is equivalent to eight percent (8%) of the compliance margin for Single-Family Buildings, or four and four-tenths percent (4.4%) of the compliance margin for multifamily buildings. In order to secure the PV compliance credit the PV system must be sized in accordance with the 2016 Residential ACM Reference Manual. Maximum PV system size in all cases is limited to no more than providing one hundred percent (100%) of annual on-site electrical usage for the building. (Ord. 1507, eff. 10/19/2018)

Sec. 8100.4 Exemptions.

A. The Building Official may exempt a covered building from the provisions of this Chapter if the Official determines there are sufficient practical challenges to make satisfaction of the requirements infeasible. The applicant is responsible for demonstrating requirement infeasibility when applying for an exemption.

B. One (1) exception to this Article is a lack of solar access for the building site. Properties that have limited solar access due to trees or other obstructions that will tend to make the PV system seriously underperform will not be held to the same standard. If solar access is reduced by thirty percent (30%) or more in terms of the total annual solar radiation available at the site compared to an unobstructed site, this is considered cause for an exception. In this case single-family residential buildings are required to meet a twenty-two percent (22%) compliance margin using energy efficiency measures only (Energy Budget that is no greater than seventy-eight percent (78%) of the Energy Budget for the Standard Design) and multifamily residential buildings are required to meet a fifteen percent (15%) compliance margin using energy efficiency measures only (Energy Budget that is no greater than eighty-five percent (85%) of the Energy Budget for the Standard Design).

C. The Building Official may exempt a covered building from the provisions of this Article if the Official determines the building has satisfied the purpose and intent of this provision through the use of alternate on-site renewable electricity systems, including wind turbines.
