Key Sustainable Features

Water Conservation Rainwater collection with 10,000 gallon tank and graywater system, low-flow fixtures, waterless urinals.

Recycled Materials Carpeting, concrete floors, structural steel, hollow metal doors, aluminum window system, glazing and ceiling tiles.

Daylighting Tall, optimally placed windows; sunscreens and open-weaved roller shades for glare control; fully dimming daylighting controls, toplighting for interior zones on top floor; many tenants have low or no cubicle walls.

Individual Controls Tunable lighting, operable thermostats in each zone (except common areas).

Transportation Mitigation Strategies Indoor, heated bike parking; individual showers; locker rooms; adjacent to 12 bus routes; car parking is shared with apartments across the street to limit space.

Other Major Sustainable Features Re-use of an abandoned site, dedicated outdoor air system and CO2 monitoring for higher indoor air quality, robust measurement and verification allowing for building research and dissemination.
