"If you have a highly insulated building, once you heat your air up to a certain temperature, it doesn't lose its heat very quickly. You could heat this building up in the middle of winter, turn all your systems off, and it would maintain an internal temperature for two or three days that would be comfortable.""Opening a building to the north is never something that's really beneficial, and it would have required a higher energy intensity for the building," Petter says, referring to a measurement used throughout the building industry reached by dividing the total amount of energy consumed by the number of square feet. "When you're looking at a high-performance building, it comes down to percentage points.""There are still financial tradeoffs," Petter says. "Until you spend enough money to get your building down to performing below that level, it doesn't make sense to pay for the extra photovoltaics. You can put more PV or insulation in, but at those higher energy intensity levels, you can get more bang for your buck with insulation."Operationally, the cutting-edge technology - more accurately, an update on an extremely old concept - is night flush mechanical cooling, in which operable clerestories are programmed to open during the coolest part of the night, flushing warm air out of the building and replacing it with cooler air brought in through apertures placed lower to the ground. The system measures both the building's interior air temperature and the differential in ingoing and outgoing volume, and when appropriate levels of both have been reached, it shuts off and the windows close.June 15, 2011ProgrammingKirk's ArmyAn Air Force Base fitness director steers his program toward combat readiness.March 31, 2006Safety & SecurityThe Beat Goes OnAs AEDs become as common as fire extinguishers in airports, hotels, casinos and police cruisers, health advocates charge that the recreation and fitness industry is wasting precious time.September 30, 2005Previous PagePage 2 of 2Top StoriesFacilitiesDaily Digs: Chicago Bears' Lakefront Stadium Plans, High School Stadium Complex, and more!The Bears are planning to build a state-of-the-art, domed lakefront stadium.
