GOALS AND SUCCESSES •To make the new office sophisticated and advanced green building design and technology • Set an example for their membership and the public, but also to demonstrate what is possible Increased productivity due to day lighting, good air quality, design innovation, integrated design process, waste reduction and avoidance • Greatest success - day lighting Remarkable day lighting, high-performance lighting system achieves lighting power densities among the best in the industry Indoor office environment www.usgbc.org
- 36. STRATEGIES •An electronic windowshade system operates to maximize good daylight and minimize glare. •Walls, ceilings and workstation panels are colored white to reflect as much light as possible. •Eco-corridor features a lighter perimeter carpeting along the window line which acts as a light shelf, reflecting natural light back into the space
- 37. STRATEGIES •With lighting controlsset to 80% maximum output, lighting power density is 54% below the ASHRAE standard. With so much daylight streaming in, use of overhead lights reduced •Biophilic strategies, those connecting staff to nature, was to provide views of the outdoors from a seated position, and 97% of all regularly occupied spaces have a direct sightline to the outdoors. •Energy use in space is monitored, including energy used for lighting, to ensure we leverage design efficiencies and systems are operating in sync. Overhead lighting
- 38. PROCESS • Space layout,windows, HVAC, lighting, and furniture selection and finishes •Interior as transparent as possible - low partition heights and interior glass features •Reduced the amount of air conditioning load in the summer • Innovative linear diffusers that would automatically deliver the supply air downward in the heating mode in the winter months and pivot the air horizontally while in cooling mode. This new technology significantly removes the thermal downdraft •Water wall which provides cooling and dehumidification
