The documentation requirement for this path is to create a representative floor plan highlighting light measurements taken in regularly occupied spaces. Your team may take the measurements in one representative space and extrapolate those results to other, identical spaces. 

Consider following Option 2: Views as an alternative, and potentially more streamlined, compliance path.

This path is more doable than other Daylight paths, with the complication that your results can be affected by shading conditions such as adjacent buildings.

Option 1, Path 3: Daylight Measurement

Assess whether your project complies with rules pertaining to ceiling obstructions, light redirection, and glare control.

Obtain documentation confirming that your project building was contaminated and that remediation was completed. Ask building management to provide an ASTM E1903-97, Phase II Environmental Site Assessment and proof of remediation. However, such documentation is not common and may be hard to find if remediation was well in the past. Alternatively, you can provide proof that the building was developed on a brownfield site, as determined by a local, state, or federal government agency via a letter or other formal confirmation. 

You may have to check local, state, and federal government (particularly the EPA) offices for lists of buildings in your area on remediated sites.

Aim for a building constructed on a brownfield site that was subsequently remediated. Consult with building management to find out if any kind of remediation was ever carried out on the property. Be sure to inquire about asbestos remediation, which also qualifies even though it does not define a site as a “brownfield.”

Refer to LEED-NC SSc3 for detailed requirements and documentation tips.
