Responsible for the creation of the LEED green building certification program, the U.S. Green Building Council (USGBC) applied its own LEED standards to the completion of its new Washington D.C. digs: a two-story, 75,000-square-foot office space that earned 94 of the 110 possible points; 14 more points than the 80 required for Platinum certification.
Helping the agency go beyond its own green standards is a Crestron A/V and lighting control system, which was designed and integrated by Audio Video Systems, Inc. In keeping with LEED goals, the integration firm used Energy Star-compliant products where possible and engaged the Crestron system to automate power management when an Energy Star product was not available. In all, the installation covers one large and two medium-sized divisible conference rooms, the lobby, game room and café on the first floor, while a small conference and medium-size, divisible conference room on the second floor have also been integrated. All of the rooms have a local, networked A/V control system powered by Crestron’s RoomView asset management software that monitors and automates the shutdown of systems after normal working hours.
Four GLS-ODT-C-2000 low-profile ceiling mount occupancy sensors in the first floor’s two medium conference rooms detect when the spaces are occupied, with advanced motion sensing for control of lighting, climate control and other devices in the space. Four GLS-LOL photocell sensors continually monitor daylight movement to dim or switch lights off when sufficient natural light is available.
Connectivity to the motion sensors detect occupants and prevent the shutdown of a display while a room is in use and to shut down systems automatically after a preset interval of no activity within the room. When video sources are connected and powered on, the system for that room automatically turns on to route the device output to the displays. Once the device is disconnected or turned off, the displays and related equipment are automatically shut down to conserve power.
Control of the medium-size, divisible conference rooms is via 12-button keypads, 52-inch LCD
