地址: Springdale, UT

建筑面积: 223 sq. meters

竣工日期: May 2000 

能源利用: A 70% reduction in energy use was met through the design and implementation of natural ventilation, efficient lighting combined with daylighting, effective glazing, insulation, a passive downdraft cooltower, Trombe walls, energy-efficient landscaping, and an energy management system.

节水方案: Using this site, previously a campground, avoided unnecessary impact of natural and cultural resources. No undeveloped lands were used. Underutilized, existing areas in Springdale were used for parking and facility development. Construction was phased to minimize disturbance. Topsoil was stockpiled, runoff was diverted to existing sediment-catching areas, existing vegetation was maintained, no soil was transported off site, and dust control was implemented in roadwork adjacent to the existing campground.

Native low-water-use grasses and shrubs were used for landscaping. Historic irrigation channels were restored. Collected rainwater joins river water and is diverted through a series of gravity-fed irrigation ditches. High-efficiency irrigation techniques and drip irrigation with a weather data controller were installed primarily to encourage the reestablishment of native vegetation. (It may be possible to achieve 100% reduction of potable water for landscaping after plant establishment.)

材料选择: 20% of materials, including stone, concrete, and paving, were manufactured within 500 miles (800 km) of the site.

室内环境品质: Cool towers (which provide over 5 air changes per hour) and operable windows provide natural ventilation to building occupants. Thermal, ventilation, and lighting systems may be controlled by users. Extensive daylighting was implemented. The building remained unoccupied for 2 weeks following construction, while commissioning and final punch items were completed.
