| 能源利用: |
4.9 kW net-metered photovoltaic array on rooftop generates about 5,800 kWh/yr.
Six small-scale wind turbines on rooftop supplying 2.4 kW charge an uninterruptible power supply unit (UPS).
High-efficiency HVAC units.
High-efficiency lighting fixtures in offices and warehouse, with occupancy sensors in offices, and LED exit lights.
Company purchases certificates for renewable power.
Third-party commissioning of building systems for improved performance. |
| 选址和节水方案: |
Recycled materials include structural steel, tilt-up concrete shell made with recovered flyash, and recycled-content broadloom carpeting.
Wheat board chair rails throughout the building. |
| 室内环境品质: |
Most of the parking lot is pervious surface, covering over 15,000 sq. ft. A grid system (InVisible Structures) covered with chipped granite reduces surface temperatures by roughly 40° F compared with asphalt pavement and infiltrates 10,000 gallons rainwater during a 1" storm event.
Three bioswales infiltrate another 15,000 gallons rainwater. Strategically placed speed bumps guide rainwater from asphalt loading dock area toward bioswales.
Hillside above asphalt loading dock area is planted in native prairie vegetative cover to minimize runoff. Prairie restoration covers more than 2 acres of the 5.5 acre site.
A rooftop collection system channels rainwater from back quarter of building to two large storage tanks inside the manufacturing facility for irrigation of the traditional landscaping facing the street. This saved 400,000+ gallons of potable water during summer 2005.
5,000 sq. ft. of green roof planted with hardy sedums (no irrigation) provide test plots to experiment with plant spacing and growth rates while reducing stormwater runoff and cooling membrane temperatures.
Predominantly white roof with high reflectivity reduces urban heat island impact.
Low-flow plumbing fixtures, including urinals and toilets, save 6,000 gallons of potable water annually. |
| 材料选择: |
Zero-VOC paints throughout building
Construction IAQ management plan
Low-emitting carpet and adhesives
Thermal comfort in accordance with ASHRAE 55-1992, Addenda 1995 |

| 相关评论: |
ERSystems’ LEED-registered manufacturing facility showcases technologies that reduce urban heat island impacts, conserve water, reduce stormwater runoff, and generate renewable energy. The rooftop doubles as a test lab for experiments with green roof plant spacing and various elastomeric coatings. Rooftop instrumentation logs surface and HVAC air intake temperatures, with data monitoring via the Internet. |
