Integrative Process v4.1 - Project Team Letter

Hi Vikas, I have not started drafting this letter yet, but did receive clarification from the v4.1 folks at GBCI. See below:

"There is no date by which the letter must be completed. While the integrative design process must begin early in the design process, the nature of the credit means that it may extend late into design or even into construction. As noted in the Implementation section of the LEED v4.1 Guide, "The letter must include a separate summary for each issue area analyzed by the project team, describing how the analysis informed the design and building form decisions in the project’s OPR and BOD and the eventual design of the project". By using a team narrative rather than the worksheet required for LEED v4, project teams have greater flexibility to tell the story of their full integrative process."

Hi Hashir, I have drafted this letter and we've had a good experience so far with this approach being accepted during design/construction review:

• Letter included a few paragraphs summarizing each early analysis category chosen
• Letter highlighted the progression of early analysis at different stages of design (typically predesign through CDs or even construction/occupancy). For example, outlining timeline of when early energy analysis was conducted in SD and when it was updated following this.
• Early analysis report or outputs listed and attached as appendix items
• Signatures included one person representing each discipline or stakeholder group. E-signatures have been the most efficient collection method.

Hope this helps!

Hi Hashir, We did not have a formal list of all team members, just listed signatures of each group's representative at the end. I could see this list being helpful to include, maybe as an appendix item, for large projects or those with many stakeholder groups. In the letter we did provide a broad overview of which groups were involved at different points of design, like you described.

Hi Aleksandra, Our team used a typical business letter format with the date, address (USGBC's address in this case), subject and a "To Whom it May Concern". That worked fine for us!
