controls All lamp sources throughout the building were selected for long lamp life and high efficiency for reduced maintenance and wattage. Photocells, occupancy sensors, an astronomical time clock, and local controls at each workstation provide full building control to suit the needs of each employee. Every applicable light source was dimmed to allow for minimal energy use while still providing necessary illumination for visual tasks. How occupants control their environment is sometimes more critical than what that environment actually is. LDA’s office uses 12 distinct HVAC zones. This allows the north side of the building to be treated separately from the south side of the building, and allows the HVAC to be used only in occupied spaces. To meet LEED Platinum A daylight transfer fiber-optic system lights the chandelier during the day. Metal halide lights spotlight it and the lobby atrium at night. The corridor (rear of room) is lit at night by color-changing LEDs integrated into the 60 ft skylight. The LEDs also avoid the “black hole” effect that skylights usually create at night. requirements, all of the units are designed to be CFC-free. Automated shading devices, automatic operable ventilation systems, a smart building computer, and local touch screen system create a space that can be customized for anyone in the office. The automated system combined with an external thermostat actually allows for the building to be automatically precooled. Insulation values exceed R-38, more than double what was required by code, and Left A 60 ft translucent skylight provides this area and the adjacent corridor with 100% of its lighting during the day. Water walls are used to create white noise typically during evening events involving a large number of attendees. A closed loop system reuses the water, pumping it back to the top. The social space encourages carpooling by giving employees a source of entertainment until their fellow carpoolers are ready to leave. © rmA Architectural Photography 30 HigH Performing Buildings fa l l 2 0 1 0 © rmA Architectural Photography
