By renovating this previously developed site, materials used for site net Zero energy PurSuit A major goal of the project is to create an nZeB, or net zero energy building, defined as creating more annual on-site energy than annual energy used. The design team’s energy model projections for both were fairly accurate — both energy produced and energy consumed values were well within 8% of actual performance. The difference has been attributed to the facility’s extended use for community functions on evenings and weekends. To close this gap, a sloped PV trellis is being constructed over the existing flat mezzanine roof. This project will increase the total onsite energy production by an additional 15% through a combination of new and relocated existing panels. existing panels will be relocated to avoid occasional shadows and optimize solar altitude orientation. This project is being financed through a solar energy rebate from the state of florida. it will provide the additional energy needed to achieve net zero energy status. infrastructure and surface parking were also retained. Construction waste was sorted in separate dumpsters, and more than 94% was recycled. Collection bins in multiple locations within the branch make recycling convenient for all occupants. Sixteen percent of materials (by cost) were extracted and manufactured within a 500-mile radius of the project, reducing the need for excessive transportation fuel. In addition, many of the interior finish materials were selected based on their high recycled content, including carpet systems, porcelain tile flooring, recycled glass wall tiles, rubber flooring with shredded and cleaned tire rubber, recycled aluminum mill work panels, and countertops of recycled paper that include inlays of bamboo, recycled credit cards and recycled currency. The building team chose lowemitting materials including adhesives, sealants, paints, wood stains, carpet systems and composite wood spring 2012 Above Interior finish materials include recycled paper counter tops with inlaid bamboo and recycled credit card details.
