Gurus -

I'm looking for (or to build) a set of US district energy projects for developer-led mixed-use/residential neighborhoods/districts.  Does anyone have a resource for this or have started something similar?   

I am not a member of IDEA but utilize their site quite often. Any other resources come to mind?  I'd be happy to... Read more

Carpet is comfortable, offers good sound control, and offers great aesthetic options. But it is typically made from petrochemicals, and carpet and its adhesives can offgas VOCs. It is also a challenge to recycle, increasing the chances that it will be incinerated or disposed of in a landfill. Broadloom carpet cannot be readily repaired if... Read more

I'd love to hear thoughts from the design, consulting, and contracting firms in this group about ways to make our specs more inclusive, or at least less exclusive to minority and women owned contractors and subcontractors and others that have not had the benefit of what a recent "Equity in Specs" presenter termed the "Fathers / Brothers / In-...

We're looking to expand our design performance group - let Peter or me know if you have someone to recommend to us! Here's the description. 

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

I was wondering if any design or contractor friend here can kindly share the carbon emission factor of excavation during construction. 

I found a paper that provides energy use rate per cubic meter and associated carbon emission in kgCO2 for different phase of construction such as excavation earth work, pouring and lifting concrete,... Read more

Hi, all.

Has anyone used Unicel's Timber Curtain Wall System? It uses engineered glulam wood mullions on the inside with aluminum mullion caps / butt joints. Has anyone gotten close to using it, but couldn't get it procured for a particular reason? They note up to 72% more energy efficienct than a conventional aluminum curtain wall and... Read more

There are a number of clear finish options available, from natural oils and low-toxicity products primarily used on residential woodwork through factory-applied finishes where specific aesthetics and/or added durability are required (such as those used on cabinetry or commercial architectural millwork). Many of these have very high VOC levels,... Read more

Has anyone had any success with achieving the LEED Building Envelope commissioning points with an alternative compliance path using the requirements of the PHIUS verifier? It seems like an unnecessary duplication to ask the client to pay for a BECx agent and a Passive House verifier. Or am I missing something? I can't find any LEED... Read more

Are FSC glulams available? By many manufacturers? Which ones?

This is a test for surveys.

Hi Green Gurus,

In this stressful time, I think it is important for us to continue to feel connected and supported.  Also, it is difficult to come to terms with the reality of what is happening.  So, I thought it would be helpful for us to share some information about the response of our respective firms to the Coronavirus.

The... Read more

Hi, curious if anyone in the group has considered using Fitwel in an existing (built) school project (K-12). 

Would be interested in hearing your experiences and if this tool is a good fit for this type of project.
