accordance with the following:

1. The proposed newly constructed building cannot satisfy all-electric building or all-electric design

prescriptive requirements based on the newly constructed building’s intended use(s) when compared to the

same building and intended use(s) modeled with natural gas under the California Energy Code; or

2. The proposed newly constructed building cannot satisfy all-electric building or all-electric design

performance requirements based on the newly constructed building’s intended use(s) when compared to the

same building and intended uses modeled with natural gas using commercially available technology and an

approved calculation method under the California Energy Code; and

3. The installation of natural gas piping systems, Zxtures and/or infrastructure in the proposed newly

constructed building is strictly limited to the system(s) and/or area(s) of the building regarding which the chief

infeasible; and
