建筑面积: 778 sq. meters

竣工日期: October 2002

能源利用: The building's annual energy consumption is expected to be 32% lower than that of a conventional building designed to ASHRAE 90.1-1999 standards. Good insulation in the roof and walls and low-emissivity glazing allowed for a reduction in the size of the building's mechanical systems. A geothermal water-source heat pump transfers heat rejected from the computer rooms and core spaces to perimeter spaces requiring heat during the long heating season.

Lighting and ventilation analyses were performed to determine the best use of operable windows for natural ventilation and windows, clerestory windows, and lightshelves for daylighting.

Due to the importance of the data collected at this facility, the equipment room was designed with built-in redundancy in the form of UPS backup and a diesel generator that can provide power for three days.

The building equipment for the weather station is in operation at all times. The computers require about four times as much energy as the rest of the building. The energy required to sustain the computer operations is listed under "plug and equipment load" below, and the heating, cooling, and ventilation needed to maintain this process load is identifed under "other" end uses.

节水方案: Water Conservation and Use

The site uses no potable irrigation. Using water-efficient fixtures, the design team reduced water use by more than 30% and reduced the use of potable water for wastewater conveyance by more than 50%.

Indoor potable water use: 55,900 gal/yr (212,000 liters/yr)

Outdoor potable water use: 0 gal/yr (0 liters/yr)

Green Strategies

Low-Water-Use Fixtures

Use low-flow toilets

Demand for Irrigation

Select plants for drought tolerance

Sites with Excessive Impacts

Avoid building and infrastructure placement on prime agricultural land

Low-Impact Siting

Avoid building in flood-prone areas 

材料选择: Ten percent of the cost of construction went to recycled products, and more than 20% of the cost of construction went to locally manufactured materials. Pressed strawboard was used for all built-in cabinetry throughout the facility.

Diversion of Construction & Demolition Waste

Seventy-five percent of the construction waste was diverted from the landfill. The two most significant strategies were the reuse of asphalt paving as asphalt paving base and the reuse of concrete, masonry, and drywall as fill at another site.

Green Products Used

Recycled-Content Acoustical Ceiling Panels

Recycled-Content Commercial Carpet Tile

Green Strategies

 

Job Site Recycling

Require a waste management plan from the contractor

Ozone Depleting Substances

Avoid rigid foam insulation made with HCFCs

Avoid sprayed-in foam insulation made with HCFCs

Post-Consumer Recycled Materials

Specify heavy steel framing with highest recycled content

Transportation of Materials

Prefer materials that are sourced and manufactured within the local area

 室内环境品质: The facility used low-emitting materials, including adhesives, sealants, paints, carpets, and composite wood. The non-perimeter spaces have controls for lighting, ventilation, and heating and cooling. The facility complies with ASHRAE's comfort standard (ASHRAE 55-1992), and windows provide both views daylighting.

Green Strategies

Thermal Comfort

Provide occupants with the means to control temperature in their area

Visual Comfort and Light Sources

Provide occupants with control of light in their area

Elimination of Indoor Pollutants

Use only non-solvent-based adhesives

Reduction of Indoor Pollutants

Use only very low or no-VOC paints

Use only very-low-VOC carpet adhesives

Pollutant Management During Construction

Minimize exposure of textiles and uncoated paper to high VOC concentrations
