any lighting that was turned on manually through the phone system. Interior lighting is primarily T8 fluorescent dual circuit fixtures. This enables the lighting to operate at 50% during McEnergy Days, a load shedding action plan. It includes lighting reductions, shutting down nonessential equipment, reduced elevator service and other mechanical, operating and occupant practices implemented on utility peak load days. The renovated areas use T5 direct/ indirect fixtures, which typically operate at 50% due to the improved daylighting and lower cubicle panels. The building also uses compact fluorescent bulbs and several pilot LED lighting installations to evaluate LED technology and identify future retrofit opportunities. Overhangs allow daylight to penetrate the space while minimizing the heat load effect of direct sunlight. intended. The retrocommissioning was completed in mid-2008 and findings were corrected throughout the remainder of 2008. Some key findings included: • • CO sensors in garage were retrocommissioning A prerequisite for LEED certification under the Existing Buildings: Upgrades, Operations and Maintenance v. 2.0 rating system was retrocommissioning the building. This process helped ensure the building mechanical systems were operating as designed and outside of calibration tolerances; The economizer mode was difficult to activate; and • The OA/RA damper did not actuate on one of the rooftop units. Resolving these issues contributed to the energy reductions identified in the previous section. Several submeters monitor gas and water consumption for process and other non-occupant related loads such as the quality labs, test kitchens and restaurant, and for the fire sprinkler equipment. In addition, hose bib meters track incidental water use on the building’s water spigots by grounds and housekeeping personnel. Parking More than 83% of the parking capacity at the COB is indoors at ground level and two below-grade levels, which drastically reduces the urban heat island effect associated with exterior asphalt parking lots. Dedicated preferred parking for alternative fuel vehicles comprises 3% of the total parking capacity. In addition, bike racks and locker/ shower facilities are provided to promote alternative commute methods. Transportation The HO campus uses two shuttle buses to transport employees to and from various buildings. These shuttles are fueled with biodiesel made from recycled fry oil recovered from the on-site restaurant and test labs. The glycerin by-product from the recycling process was used to make other green features Water efficiency The site and building include several other sustainable features. Native or adaptive vegetation makes up 75% of the COB grounds, minimizing irrigation needs. Two lakes on the campus capture rainwater that is used to irrigate a minimal amount of manicured turf and flowerbeds. Low flush rate interior plumbing fixtures with automatic valves and automatic sensor faucets further reduce consumption of potable water within the building. Native or adaptive vegetation makes up 75% of the COB grounds. 24 HigH Performing Buildings fa l l 2 0 0 9
