I don't know if this is the appropriate forum for this question but I don't know where else to ask my question and I also thought it might be of interest to this group.

We are seeking someone to provide an expert opinion regarding an EEO discrimination case related to a Federal agency’s failure to grant a request for reasonable accommodation due to a disability. An employee asked for an office with a window as a reasonable accommodation for seasonal affective disorder. The agency denied this request with the explanation that because the employee was in a “green building,” no offices could be built on the building’s windowed exterior. We believe that the employer's reasons for denying the request are not supportable. In fact the evidence we have suggests that the agency denied the request without seeking input from anyone with knowledge in this area. We would like to know, does the agency's explanation make sense? Is the fact that this is a green building even relevant? If so, what specific “green” standards applied that would have been relevant? (We're assuming IEQ 8.1 and 8.2, but are there others?) Could the agency have granted the request, and if so, how? – e.g., could they have constructed an office with standard walls or with glass walls? Or could one of the building’s existing conference rooms, which had exterior windows, have been used as an office? Is it possible that moving the employee to an office with an exterior window would have even improved the LEED score?

Additional information - the building is 100% glass, 362,083 square feet, built in 2009. The building was silver certified in 2010 (LEED CI 2009). Points = 0 for daylighting and 0 for views. The building was gold certified in 2014. Points = 1 for daylighting and 1 for views. See http://www.gbig.org/buildings/123251 

The request was denied in 2013. 

I'd greatly appreciate any informal background information or advice anyone can provide! I'd also appreciate any information or referrals regarding how to find an appropriate expert witness who would be available on a short timeframe.

Thank you in advance!
