Our team has selected to provide operable windows and light controls to achieve this credit. Our building skin is a repeating pattern of precast concrete panels and a glass curtainwall system. The building will house an open office work environment. Currently we have ?x? operable windows spaced 1? apart on the north and south elevation and 2? apart on the east and west elevations. It appears that the number of windows might be lower than specified however the large size windows exceed the normal operable office window. The intent of the goal appears to be achieved although we would like to assure that the requirements of the credit do not keep the project from earning this point. If quantity of windows is truly the issue our fenestration pattern dictates that the most cost effective place to add operable windows would be directly on top of those already in the design or simply break the ?x? window into two \'x? windows. Neither of these strategies appears to change the intent but would bring us within the credit guidelines. Also, our design team would like to confirm whether corridor space in an open office environment is considered a "regularly occupied area". There is a 6\' circulation path along the entire building perimeter that does not contain any work or meeting areas.
The intent of the credit is to provide a high level of occupant control at the perimeter of the building. The requirement results in an operable window at about every 13 feet along the exterior wall. As described, the project does not provide this level of functionality with operable windows occurring at roughly half the expected frequency. The number individual zones is then also about half the expected frequency, so the intent is not met. If the circulation zone is within the open office environment, then it is not a corridor. It is considered part of the regularly occupied area by LEED. Applicable Internationally.
