Our project is a full service automobile dealership that includes a single large open room designated as the Service Shop. The Service Shop is approx. 20, 000 sq. ft. This area is approx. 53 % of the total regularly occupied area 37,730 sq. ft. of the project per the Views Credit criteria. The area does not include desks or seating, but is the primary work station (locations) of several employees. The guidelines for the views credit compliance assumes a "42 inches (average seated height) sight line from a point at 42 inches above finish floor to the perimeter vision glazing" to determine compliance with the views credit. In the Service Shop area employees stand to perform their work responsibilities which is servicing cars. We would like to propose a line of site at "63 inches above finish floor to establish the sight line so that from a point at 63 inches above the finish floor to the perimeter vision glazing" can be used to determine compliance with the views credit requirements. The 63 inches above finish floor is derived from the average of the two values for an average standing male and female person per the human dimensions anthropometric data for adults found in the Architectural Graphic Standards, by Charles George Ramsey, 10th Ed., American Institute of Architects. The project team would like to establish a standing height line of sight for the Service Shop Area that allows us to locate vision glazing for the staff to access views and also comply with the views sight line requirement for this credit. Will the USGBC accept documentation that shows the "standing work area" in the service shop with a sight line located at 63 inches above finish floor to perimeter vision glazing to provide views for the building occupants?
The CIR is asking for a specific exemption to the 42" seated height sight line that is established for determining access to views for regularly occupied spaces. The project contains an automotive service shop where workers stand throughout the day to perform their duties. The project team has proposed a 63" standing sight line for determination of access to views for auto service shop. As the service shop is a non-typical work environment where the majority of work is conducted by standing employees, the 63" sight line is acceptable for documenting access to views. It should be noted, that this modified sight line is only allowable for the auto service application of this project. All other office and work areas must still comply with the seated height sight line of 42" noted in the NCv2.2 Reference Guide. Applicable Internationally.
