California Energy Code Section 100.0(e)2A (Newly constructed
buildings – All newly constructed buildings) is hereby amended
to read as follows:
100.0(e)2A. All newly constructed buildings. Sections 110.0 through 110.12 apply to all newly constructed buildings within the scope of Section 100.0(a). In addition, newly constructed buildings shall meet the requirements of Subsections
B,
C,
D,
E, or F, as applicable; and shall be an All-Electric Building as defined in Section 100.1(b).
For the purposes of All-Electric Building requirements, "newly
constructed buildings" shall include the buildings defined in Section
100.1 as well as newly constructed additions and improvements in existing
buildings where more than 50 percent of the exterior walls are removed
or 50 percent of the wall plate height is raised. The Chief Building
Official shall make the final determination regarding the application
of this section.
For the purposes of All-Electric Building requirements, "newly
constructed buildings" shall not include newly constructed additions
and tenant improvements in existing buildings except as defined above.
Exception 1: F, H, L Occupancies may utilize natural
gas and shall provide installed prewiring for future use of electric
appliances.
Exception 2: This exemption shall apply only for
public agency owned and operated emergency centers. To take advantage
of this exception applicant shall provide third party verification
that All-Electric space heating requirement is not cost effective
and feasible.
Exception 3: Non-residential kitchens may not utilize
natural gas for cooking appliances unless the applicant establishes
that there is not an all-electric option for the kitchen using commercially
available technology. If the Building Official grants an exception,
EnergySTAR rated natural gas appliances shall be used.
Exception 4: An All-Electric Building may receive
power from equipment, located outside the building, that utilizes
natural gas, propane, or other fuel to generate electricity. The Chief
Building Official may grant an exception to allow natural gas or propane
plumbing within an all-electric building to fuel such equipment if
the applicant provides a third party verification that the standard
electrical grid is not sufficiently reliable to meet the power needs
for the intended use of the building.
Exception 5: If the applicant establishes that
there is not an all-electric prescriptive compliance pathway for the
building under the
Energy Code, and that the building is not able
to achieve the performance compliance standard applicable to the building
under the
Energy Code using commercially available technology and
an approved calculation method or if it is demonstrated that there
is equivalent greenhouse gas reduction, then the Building Official
may grant a modification. If the Building Official grants a modification
pursuant to this Exception, the applicant shall comply with the pre-wiring
provision of Note 1 below.
Note 1:
|
If natural gas appliances are used in any of the above
exceptions 1-3, natural gas appliance locations must also be electrically
pre-wired for future electric appliance installation. They shall include
the following:
|
|
1. A dedicated circuit, phased appropriately, for each appliance,
with a minimum amperage requirement for a comparable electric appliance
(see manufacturer's recommendations) with an electrical receptacle
or junction box that is connected to the electric panel with conductors
of adequate capacity, extending to within 3 feet of the appliance
and accessible with no obstructions. Appropriately sized conduit may
be installed in lieu of conductors;
|
|
2. Both ends of the conductor or conduit shall be labeled with
the words "For Future Electric appliance" and be electrically isolated;
|
|
3. A circuit breaker shall be installed in the electrical panel
for the branch circuit and labeled for each circuit, an example is
as follows (i.e. "For Future Electric Range"); and
|
|
4. All electrical components, including conductors, receptacles,
junction boxes, or blank covers, related to this section shall be
installed in accordance with the California Electrical Code.
|
Note 2:
|
If any of the exceptions 1-3 are granted, the Building
Official shall have the authority to approve alternative materials,
design and methods of construction or equipment per CBC 104.
