                                             Solar Thermal Hot Water Installations

                            In hot water?
                            Did you know, space and water heating are responsible for approximately 75%
                            of all greenhouse gas emissions. Solar thermal hot water is the most cost-
           Berkeley’s


                            effective and environmentally friendly solar energy technology. Solar thermal can
                            supply most of your hot water needs and can even be used to heat your home.
                            Increasing the amount of clean renewable energy is a critical component of the
                            Berkeley community efforts to reduce green house gases. The City of Berkeley
                            encourages the installation of renewable energy systems by providing affordable
                            solar thermal permit fees.

                            Types of solar thermal hot water systems
                            Solar water heating systems use relatively simple technology, including a
                            storage tank and a solar collector. There are two types of solar water heating
                            systems: active, which have forced circulating pumps and controls, and passive
                            which do not. Additionally, you can choose between indirect or direct circulating systems for active solar
                            thermal systems. Nearly all solar water heating systems require a back-up system for cloudy days and times of
                            increased demand.

                            Energy Efficiency First
                            The first step in any solar thermal installation is to implement conservation measures to reduce energy and
                            water use by fixing leaks, installing low-flow fixtures and purchasing energy efficient appliances. Conservation
                            reduces expenses, greenhouse gas emissions, saves water and minimizes the size of your thermal system.

                            What Permits are Required by the City of Berkeley to Install Solar Thermal?
   Builders
                            ZONING PERMITS
                                     Solar thermal projects do not require zoning permits or design review (California State Code, Section
                                     65850.5). The Planning Department offers free non-binding design review evaluation of solar

   City of Berkeley                  For all building projects requiring Design Review, Planning Department staff will need sufficient
Green Building Initiative            information about the solar thermal installation to evaluate the proposed building design.
         2009                        Note: Design Review is generally required in the following Zoning Districts: Manufacturing,
                                     Commercial, and some projects in R-4 Districts. Check the Planning website to determine the Zoning
                                     District of your property and the applicability of Design Review requirements.

                            BUILDING & RELATED PERMITS
                                     Plumbing permits and possibly electrical permits are required for all solar thermal hot water
                                     installations. If structural work is needed to support the system, a building permit will be needed as
                                     well.

For a complete list of requirements please refer to the Solar Thermal Hot Water
Checklist (available in the Planning section of the Online Service Center at www.cityofberkeley.info/onlineservice or in per-
son, at the Permit Service Center). Submit four sets of plans, minimum 11” x 17”, that include location of equipment, wiring
diagram, framing plan of rafters and equipment specification sheets.
•   Structural plans may be required for reinforcing the roof rafters to carry the additional load. For example, if you have
    an older building, and the rafters are 2 x 4’s and 32” apart, you will need reinforcement. If you have a truss roof with
    tile and want to add additional load, you will need to consult an engineer.

•   Fire Department requires that panels be installed at least 18” down from the ridge of the roof on both sides for one
    and two unit family dwellings. Fire Department approval is required for commercial and multifamily buildings to ensure
    site-specific access for fire personnel. For more information, please contact the City of Berkley Fire Department at
    510-981-5585.

permit and plan check fees will be based on the valuation of the structure.


Why Install Solar Thermal?
                                                                                   Berkeley Greenhouse Gas Emissions
Residential natural gas is the largest source of greenhouse gas                              by Source (2005)
emissions from buildings. In November 2006 Berkeley voters over-
whelmingly approved ballot Measure G to reduce the community’s
greenhouse gas (GHG) emissions by 80% by the year 2050. The                                                            Transportation
