I’m a volunteer member of the ASHRAE 209 ("Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings”) Committee.  Are you familiar with ASHRAE 209? It was first published in 2018, and it outlines a process for incorporating energy modeling into the design process. 

From the forward:

Hi all, are there requirements to include/submit backup documentation to the CC excel template? Or is it just the template itself that gets submitted? The question is coming up from our leadership over what documents are public vs internal.

Has anyone had experience working with Hyper Metro (http://hypermetro.co/)? If so, did you find this company to provide value especially in dense urban environments where on-site segregation poses challenges to manage multiple C&D material streams on site?

Hi all: I'm looking for experience, insight, or advice as it relates to ISO 14001. I know it is more popular internationally than in the US, and I am trying to ascertain if the the value-add is greater than the cost and effort. If your company is certified, or even if you have looked into it in any capacity, I would love to pick your brain.... Read more

HI All,

I have been tasked with putting together a cost comparison of doing a LEED v4 Gold building vs. making that same building Passive House. Obviously they are two different systems, with two different outcomes, and it's not really intended as a total apples to apples cost comparison, but more a value comparison for a developer....

I know these products exist, but I haven’t had to spec or work with any, so I’m reaching out.

The project is in MA, so I'm also soliciting recommendations for products and/or companies who are experienced using... Read more
