46 FC Gulf Freeway Office Building experiential Design Energy savings for four similar office buildings in the Houston area started with planting native vegetation on one roof. Designers found that the roof’s added insulation value and lower temperature reduced the cooling load, allowing them to reduce chiller capacity in future projects. FC Gulf Freeway’s graywater and condensate is reclaimed and used to flush toilets and urinals. Sheltered balconies on the eastern, western and southern faces shade glazing from direct sun. 62 National Australian 70 Built Environment Tyson Living Rating System Learning Center Resetting expectations A new law in Australia will require the disclosure of energy and greenhouse gas efficiency when office buildings of a minimum size are sold or leased. For the past 10 years, the program known as NABERS Energy has aimed to reduce greenhouse gas emissions by rating buildings according to their actual energy consumed during a year. Tenants are increasingly seeking buildings with high NABERS ratings and the federal government is requiring that government agencies aim for 4.5 (out of five) stars. nature’s Way Washington University’s research and education center outside of St. Louis aims to meet goals of net zero energy and net zero water use. Composting toilets require no water for flushing, and a rainwater harvesting and treatment system provides potable water. The building nearly reached net zero energy use in its first year of operation. Additional photovoltaic panels, added insulation, caulking and sealing to reduce infiltration, and HVAC operation adjustments are expected to help the building’s energy production exceed its energy use during its second year. Trees from the property that were removed as part of a forest restoration project or that fell during storms provided wood for the siding, eaves and floors. 56 Capturing Condensate One way to reduce water use is by collecting condensate. The water can be reused for landscape irrigation, cooling tower makeup, toilet or urinal flushing and water features. Initial results from the authors’ research provide condensate collection potential for climate areas of the U.S., and estimated costs and payback for installing a collection system. fa l l 2 0 1 0 HigH Performing Buildings 5
