A discussion of other metal roofs in the area ensued. Ms. Burns advised that the Fire Department Headquarters had a standing seam metal roof, which was very attractive_ She noted that they wished to attain three goals with the prof ect_ achieve LEEDTM certification, ensure that the facility was operational from a fire department perspective, and ensure that the facility was built to minimize long-term mat ntenatice costs. It has been demonstrated over time that a standing seam metal roof provides the best long-term maintenance for a facility_ She believed that a metal roofing material could be found that would achieve the goals of low maintenance costs and effort, the LEEDTM certiF cation, and the reflectivity. Commissioner Maas noted that the new Fire station will be located in the gateway to the City, and that it was very important that it be attractive. She believed that the design should relate to the surrounding houscs_ She inquired how much of the design reflected the LEEDTM aspect versus the aesthetic appeal. Mr. Van Cleeve noted that the materials included horizontal cement siding, aimed they downscaled the building with intermittent columns. The size of the glass panels was downscaled to produce a more residential character to complement the neighborhood, and a large expanse of glass was used for the LEEDTM certification. The glass not only would bring in natural daylight, but also acted as a heatsink for the building in the wintertime_ The scaling of the building was residential in character in the residential areas of the fire station, near the apparatus bay_ He noted that it was a challenge to design in a residential scale because of the size of the overhead doors required for the fire station. The massing of the roof was kept shallow, and cross-ventilation also contributed to the LEEDTM features. In response to an inquiry by G'ommissioner Maas, Mr. Van Cleeve confirmed that they had seen the design of the gas station as a model of residential blending_ In response to an inquiry by Commissioner Maas, Mr. Van Cleeve noted that the arches were unique to the project, and that it was a LEEDTM aspect of the project to get a draft inside the space to remove the hot air. Commissioner Maas noted that she would prefer the arches to be softened. Anne Ludwig, Alameda County Waste Management Authority, thanked the Commission for its interest in green building_ She noted that they had been involved in the building design from the outset to match its design to the green building and energy goals suggested by the Planning Commission and the City Council. She noted that there were different ways to accomplish the performance of a LEEDTM characteristic, and that it was not a prescriptive element. In response to an inquiry by Commissioner Sedlak, Mr. Van Cleeve replied that the total electric peak load of the building was estimated to be between 8 to 10 KV. Commissioner Sedlak noted that the PV panels were generally designed to handle between 50% to 75% of the peals load. PLANNING COMMISSION MINUTES January 8, 2003 Page 4
