s u s ta i n a B l e d e s i g n cOsts and savings Block 225 was procured as designbuild project with a stipulated sum, or best value delivery, of $75 million. The design and construction teams, using an integrated design approach and reinvesting over a half million dollars from a shortened construction schedule, were able to provide additional sustainable features within the budget at no additional cost. The cost of the sustainable features was estimated at roughly $1.2 million. The costs include additional design fees, materials testing, ufAd and application fees for leed gold. The design and construction team also researched and applied for grants to fund additional sustainable features, including the 310 building integrated solar panels, recycled rubberized asphalt street paving, and the daycare playground surface made from recycled sneakers. The integrated design approach made a significant impact on the design production and construction schedule and costs. The contractor and subcontractors were on board early in the design process. This allowed the architect to work directly with the exterior envelope subcontractors to develop the shop drawings directly from the design intent documents. This streamlined the design document development and shop drawing submittal and review, significantly shortening the process. The energy model predicted that the sustainable features would yield an average savings of $185,000 a year, resulting in an estimated payback period of less than seven years. However, the design team has been unable to verify the accuracy of the modeled energy cost savings. The building has been in operation since 2002, meaning that in theory, the principal investment has been recouped. The state should continue reaping savings each year from reduced operational costs. findings from the ufAd field study of sacramento Capitol Area east end Complex will be posted at http://www.cbe.berkeley.edu/research/ briefs-eastend.htm. landscape designers for Pocket Park selected plant species that attract beneficial insects and animals, providing natural pest control. The patterned marble used for the stone floors in the main lobby and elevator lobby was recycled and reused from the original sacramento library and Courts Building, circa 1923. fa l l 2 0 0 9 HigH Performing Buildings Photo © erhard Pfeiffer Photo © erhard Pfeiffer http://www.cbe.berkeley.edu/research/briefs-eastend.htm
