New LEED® Pilot Credit Blurs the Line Between Architects and Contractors Standard of Care

The new LEED pilot credit "Prevention through Design" (PtD) seems to blur the traditional boundary between architects and development contractors. Architects have historically refrained from inserting themselves into the means and methods of construction health and safety. Qualifying for this credit will undoubtedly lead to an evolution and adaptation of an architect's standard of care. 

Under this proposed credit, the design of a landscaped roof would include safety methods during construction for installation of the vegetative system especially along a roof edge. The credit also encourages architects to think about building operation and maintenance functions and incorporate features such as guardrail parapets to protect against falls during roof maintenance. According to the LEED Pilot Process Worksheet, the architect is a responsible party and must describe any safe operation and maintenance plan items that need to be communicated downstream to the building owner for the development of additional protective measures.

If you want to pursue this pilot credit and you aren’t sure how, look at the way architects have crafted documentation for a similar credit, MRc2 - Materials & Resources Building Product Disclosure. The Environmental Product Declaration portion of MRc2 includes the manufacturer's confirmation as to the presence of chemicals with known health risks. Architects seeking credit MRc2 need to be aware of how the standard of care is evolving in response.

The construction crew should be informed of product health risks. The pilot credit Prevention through Design does that but choose it carefully within your standard of care.
