Hello all,

We are having a mini office debate on fiberglass vs aluminum windows for use in schools (k-12) in Massachusetts. In the past we have always used aluminum windows on our schools, for durability. However, their performance is not as great as other products that are up and coming on the market. There is some hesitation to switch... Read more

Using energy for cooling during peak hours places a large demand on utilities, is expensive, and can be less efficient than off-peak energy production.

BuildingGreen-Approved Thermal Energy Storage

Anyone have experience with electric boilers? I think in cold climates it's perhaps the first thought when trying to reduce scope 1 emissions in an HVAC application that would have historically used gas-fired boilers... but it seems like they're only an incremental improvement compared to heat pumps / geothermal / VRF type solutions. We haven't... Read more

Hi all,

Hello All - It is so wonderful to virtually meet everyone and read through introductions. I'm a believer that positive change starts with groups of passionate and like-minded people organizing, and I think this group has the potential to push our industry forward, as well as offer a place for support and knowledge sharing.

I am Director... Read more

Hello all,

Could any of you point me out to recent studies showing the health impacts of plastic piping vs. copper piping? 

We have a project where NIRON or Aquatherm are proposed as a VE item in lieu of copper.  I know there is some studies showing PEX and PVC piping health impacts, but I can't seem to find anything on these 2... Read more

Hi,

We have a market-rate housing highrise project that is going through VE right now: we need cheaper/lighter rainscreen claddings than precast concrete or GFRC.

If you've gone through this similar exercise, I would greatly appreciate recommendations for cladding manufacturers/products with EPDs available. We are open to metal... Read more

Hi all - I can't remember this topic being posted recently so here goes. With fossil fuel free finally being something our clients are increasingly wanting to know about, we are stuck on diesel generators. They have several advantages including: cost, inherent refillability from a truck, reliability, and are the market standard. In initial... Read more

Reaching out to the collective knowledge here.  With interest in circular economy and building reuse growing, is anyone leading the charge for the concept of building reuse as a tool for maintaining community identity?  Has anyone seen successful projects with this concept in mind?  I was just in a discussion with a bunch of SDLers, and while...

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...
