Preservation Standards AND Guidelines August 1, 2012 4.7 FEATURES FOR IMPROVING ENERGY EFFICIENCY IN NEW CONSTRUCTION POLICY: The installation of new features to improve energy efficiency is appropriate as long as they do not detract from the historical appearance of the property or district. JUSTIFICATION - DESIGN: Contemporary or new energy and energy saving features should be placed out of public view and not detract from the historic character of a building or district. JUSTIFICATION - SUSTAINABILITY: The practical applications of alternative energy methods continues to progress and the cost-benefit ratios of applying this technology to older buildings is expected to become more attractive in coming years. The installation of alternative energy sources, where practical and economical, are encouraged to conserve energy and aid sustainability efforts. REVIEW NOT REQUIRED Geothermal and ground source heat pumps 4.7.1: Geothermal heat pumps, also known as ground-source heat pumps, uses the earth‘s constant temperature, rather than outdoor air, as an exchange medium. 4.7.2: Geothermal heating and cooling systems can save 20-70% of energy costs, depending on the season. Installation of such a system, involving drilling of holes in the ground, does not effect the exterior of a building and offers significant energy savings. 4.7.3: For geothermal equipment visible above grade, reference the same recommendations and requirements for mechanical equipment in the ―Site and Landscape Considerations‖ chapter. Geothermal systems use the constant temperature of the earth to exchange hot and cold air. Oklahoma City Historic Districts 120
Preservation Standards AND Guidelines August 1, 2012 Appropriately placed solar panels (left) and solar shingles (right) at back roof lines. ADMINISTRATIVE REVIEW: ACTIONS THAT REQUIRE REVIEW AND MAY BE ADMINISTRATIVELY APPROVED 4.7.4: Solar panels and solar shingles must be installed on back facing roof slopes and lay flat on the roof slope. They must not be visible from the public right-of-way or from streets including side streets for corner or interior lots. 4.7.5: Southern exposures receive sunlight during the entire day, making them the ideal location for solar panels or shingles. However, solar panels and shingles are not permitted for the front (south) roof slope of south-facing buildings. Solar panels and solar shingles are better suited for north-facing buildings whose south-facing roof slope is only visible from the back yard. 4.7.6: Solar panels for south-facing buildings are encouraged as free-standing solar panels installed in a back yard and out of public view. 4.7.7: Solar panels may be installed in back yards, as long as the height of the panel and the mounting system combined is less than six feet tall and they are not visible from the public rightof-way and adjacent properties. Left: an appropriate location for solar panels, out of public view and screened in a back yard; right: solar panels should not be sited on rooflines that are visible from the public right-of-way. COMMISSION REVIEW: ACTIONS THAT REQUIRE REVIEW BY THE HPC Wind turbines 4.7.8: Wind turbines require open space to harness energy from moving air which usually means that equipment needs to be installed at a height taller than any other structures or trees. This energy generation method will likely not prove practical in urban historic districts and is not permitted. 4.7.9: The Historic Preservation Commission may reconsider permitting wind turbines if sufficient advances are made in the technology to ensure compatibility with historic buildings and districts, for example, by meeting the requirements for landscape elements in back yards (not visible from the public right-of way or neighboring properties and less than six feet tall).
