5.201.3 Pool Heating—Non-Residential, High-Rise
Residential, and Hotel and Motel Buildings.
| |
|
(a)
|
For new pool construction, if the pool is to be heated, an electric
heat pump water heater or a solar thermal system shall be used for
such heating.
|
|
5.201.4 Solar Photovoltaic Installation Requirements for
Major Additions to Non-Residential, High-Rise Residential, and Hotel
and Motel Buildings.
| |
|
(a)
|
All major additions to non-residential, high-rise residential,
and hotel and motel buildings are required to install a solar electric
photovoltaic (PV) system. The PV system installed must have a minimum
total wattage 2.0 times the square footage of the footprint of the
addition (2.0 watts per square foot).
|
|
(b)
|
The requirements of this Section shall be waived or reduced,
by the minimum extent necessary, where: (i) production of electric
energy from solar panels is technically infeasible due to lack of
available and feasible unshaded areas; (ii) the PV system size required
is less than 1,200 watts DC; or (iii) the dwelling has an existing
functioning grid-tied PV system meeting the electrical utility's interconnection
requirements.
|
|
(c)
|
The requirements of this Section shall take priority if there
is a conflict between compliance with Section 5.201.3 through use
of a solar thermal system and compliance with this Section.
|
|
EV charging receptacles required by this Section shall be located
in at least one assigned parking space per dwelling unit where assigned
parking is provided but need not exceed 50% of the total number of
assigned parking spaces provided on the site.
|
|
Exceptions:
|
|
1. Areas of parking facilities served by parking lifts, including,
but not limited to, automated mechanical-access open parking garages
as defined in the California Building Code; or parking facilities
otherwise incapable of supporting electric vehicle charging.
|
|
2. Hotels and motels may substitute Level 2 EV chargers for
some or all of the required EV charging receptacles. Where Level 2
EV chargers are installed in place of low power Level 2 receptacles,
at least 50% of the installed EV chargers shall be equipped with J1772
connectors.
|
|
Exception:
|
|
1. Areas of parking facilities served by parking lifts, including,
but not limited to, automated mechanical-access open parking garages
as defined in the California Building Code; or parking facilities
otherwise incapable of supporting electric vehicle charging.
|
|
An automatic load management system (ALMS) may be used to reduce
the maximum required electrical capacity to each space served by the
ALMS. The electrical system and any on-site distribution transformers
shall have sufficient capacity to deliver at least 3.3 kW simultaneously
to each EV charging station (EVCS) served by the ALMS. The branch
circuit shall have a minimum capacity of 40 amperes, and installed
EV chargers shall have a capacity of not less than 30 amperes.

Notes
| |
|
(1)
|
For concrete strengths between the stated values, use linear
interpolation to determine cement and/or GWP limits.
|
|
(2)
|
Cement of any type per ASTM C150, ASTM C595.
|
|
(3)
|
Project applicants can choose to comply using the maximum cement
limits OR the maximum global warming potential limits.
|
|
5.409.3.6 Allowable increases.
| |
|
1. Cement or GWP limits shown in Table 5.409.3.5 can be increased
by 30% for concrete demonstrated in writing to the Building Official
or for Public Works Projects, the City Engineer, as requiring high
early strength. Such concrete could include precast, prestressed concrete;
beams and slabs above grade; shotcrete; and other applications as
demonstrated in writing by the professional engineer or other licensed
professionals.
| |
|
2. Approved Cements. The industry-average EPD describing Portland
cements produced in the United States by the Portland Cement Association,
certified by ASTM, lists a Portland cement global warming potential
of 922 kg CO2e/metric ton. If your plant specific
EPD for a cement or blended cement, demonstrated to the Building Official
by an approved EPD, is lower than 922 kg CO2e/metric ton an increase in cement is allowed (e.g. use of ASTM 595
Type 1L Cement). The maximum cement content may be increased above
the compliance level in Table 5.409.3.5 proportionate to the percentage
difference in GWP of the plant specific EPD and the industry-average
922 kg CO2e/metric ton.
|
|
Formula: 922 - Plant Specific GWP = Difference
|
|
Difference/922 = Percent Allowable Increase
|
|
922 - 900 = 22
|
|
22/922 = 0.02.
|
|
5.409.3.7 Exemptions. If an applicant for a project
subject to this chapter believes that circumstances exist that make
it a hardship or infeasible to meet the requirements of this Section,
the applicant may request an exemption in writing to the Building
Department or Public Works (for City project or work within the public
right-of-way). In applying for an exemption, the burden is on the
applicant to show hardship or infeasibility. Circumstances that constitute
hardship or infeasibility may include:
| |
|
1.
|
There is a lack of commercially available material necessary
to comply with this Section. Applicant must provide written notice
from at least two local concrete suppliers that there is a lack of
commercially available materials necessary to comply.
|
|
2.
|
The cost of the concrete mix that achieves compliance is more
than the cost of a 100% Portland cement (ASTM C-150) or a 100% Portland
limestone cement (ASTM C-595 Type 1L) mix. Applicant must provide
quotes from at least two local concrete suppliers comparing the cost
of a 100% PC (ASTM C-150) or 100% PLC (ASTM C-595 Type 1L) mix and
equivalent strength low-carbon concrete mix.
|
|
3.
|
Emergency purchases made in conformance with Section 2.24.240.
|
|
4.
|
Building permit applications submitted over the counter are
exempt from this Section.
|
|
5.
|
This Section does not apply to pre-packaged proprietary concrete
bags used for small quantities (less than three yards) or where there
is an immediate need for on-site concrete mixing.
|
