Specifications for LEED “Certifiable” Projects: 4 Approaches
Many owners and municipalities are requesting LEED “certifiable” buildings from their design teams. How is a specifier to respond?

In our experience with over 200 (real) LEED projects, we have seen four approaches.
Approach 1: Declare an early victory
The team completes the LEED scorecard and declares victory. There is no mention of LEED in the project manual and the contractor is asked to “make the right green choices.” There is no review of the scorecard after construction. While this is clearly a useless LEED approach, there are many who accept this result. In fairness, some are municipalities that are not able to mandate certification, others are architects who believe their professional training and personal commitment is the correct measure of sustainability.
Specifier’s Response: As always, at least include low-VOC products, high-performance products, and construction waste management in your specs.
Approach 2: Sprinkle in some requirements
The team completes the LEED scorecard, makes a determination of which design credits could be easily achieved, and includes only a few requirements in the specifications. Perhaps construction waste management, FSC-certified wood, and Green Label Plus carpet are sufficient to demonstrate some interest in sustainable design. Data-intensive credits such as recycled content, regional materials, and low-emitting materials are typically avoided. Again, the scorecard is not evaluated after construction.
Specifier’s Response: Match the specs with the LEED credits selected. Include submittals at the level of detail that a LEED audit would require, such as chain-of-custody (CoC) documentation for FSC products and VOC levels for paints, coatings, sealants, and adhesives.
Approach 3: Everything but submitting for LEED review
The team completes the LEED scorecard, includes it and all relevant requirements in the project manual, and collects all the data from the contractor, but does not submit to GBCI for certification. The team makes an internal evaluation of whether the goal has been obtained, and declares success. This approach is frequently taken at colleges, where those that manage the projects need to respond to various faculty and student initiatives. There is some certainty that LEED Certification would have been achieved, but typically there is no energy model, no commissioning—generally, little attempt at any credit which involves increased expense.
Specifier’s Response: Again, match the specs with the LEED credits selected. Note that the credit numbering and language for all the different LEED rating systems is slightly different—be sure which LEED program the team is following.
Approach 4: Go beyond LEED
The design team is actually committed to sustainability, and regrets the owner can’t or won’t fund LEED Certification. The energy model is developed early and really informs the design. Products that meet the VOC limits, regional goals, recycled content are specified into the project without reference to LEED. The contractor is asked to include sustainability in their product choices. The contingency fund for construction includes sustainability as a reason for a change order. After all, isn’t that what design is all about—understanding the owner’s requirements and delivering the best result for the funds available?
Specifier’s Response: Same as Approach 3 above, but now there’s the opportunity to go beyond LEED requirements. Make sure environmentally committed firms like Interface and Kingspan have an opportunity to bid. Ask the project owner what their standard products are, to help minimize waste in the future. Look downstream and make sure the NFPA fire door inspections are actually done and documented.
