ENERGY ASSES = PROCESS FOR GENERIC MULTISTORY ATRIUM TYPES

In addition to the environment that atriums provide, the daylight admitted in to such spaces can be ut i-l ized t o displace part of the e l e c t r i c l ight ing load during the daylight periods. While within the atrium i t s e l f only the l ighting required for circu-lation or plant growth i s displaced, the surrounding perimeter spaces (which a re often off ices) can a lso benefit from available daylight that can supplement e lec t r i c task lighting. I f the e lec t r i c l ighting system can be e i ther turned off o r dimned when day-l ight is available, energy savings can be achieved. Several prototype atrium configurations within a "standard " building a re addressed to study the analysis process f o r daylighting energy performance
