Hi All:  We are in the design phase for a 5,700 SF project in NH. The team is taking care to drive down embodied carbon where possible. It will be NZE.

Hello all,

Does anybody know of a substitute for Ecotect's solar tool? I use it to very quickly test shade options and I love how I can easily test horizontal and vertical elements, tilting and rotating them. I can have a window with the façade on one side and the sun path with the shadow mask on the other side. It is easy to use and... Read more

We just heard from one of our more progressive clients that they are pulling Mohawk from their shelves and are no longer allowing it on their projects. Apparently there are some chemical ingredients they objected to, but more importantly the manufacturer "lied" to the client about the content. Does anyone have an idea what this might be about?...

Has anyone done a LEED Homes and a NGBS certification and have insight into the differences, challenges, etc between the two?

For those of you who are close to CLT and mass timber, has the jump in US wood price also impacted the pricing of CLT on your projects, or viability of CLT compared to the cost of steel or concrete frame buildings?  

If anyone has price data comparing CLT today to pre-Covid pricing or any metric that would describe the percentage change... Read more
