地址: Springdale, UT
建筑面积: 706 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, effective glazing, insulation, passive downdraft cooltowers, Trombe walls, photovoltaics, energy-efficient landscaping, and an energy management system.
The roof insulation is Structural Insulated Panels (SIP's). The walls are 6-inch steel studs with a spray-in-place foam insulation.
The cooltower design was adapted from a technique used to condition outdoor patio spaces. Hot dry air is drawn into evaporative cooling pads at the top of the tower. The air is now more dense and falls naturally through the tower into the space. High windows in the building relieve the hot air.
12% of the total energy load is provided by on-site PV, with an additional 10% allowed-for in the building design. 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: Green Strategies
Design for Materials Use Reduction
Reconsider whether all space demands in building program are needed
Recycling by Occupants
Specify recycling receptacles that are accessible to the occupants
Transportation of Materials
Prefer materials that are sourced and manufactured within the local area
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.
