Dear all,

For a specific existing building application, we are looking for a half inch insulating glazing unit, preferably with low-e coating. Based on my research, 5/8" seems to be doable (1/8" glass + 3/8" air gap + 1/8" glass) but I'm yet to find a viable 1/2" solution. Have you come across any on your projects? Thanks for your...

We've been doing some work gathering actual energy data on our recent projects. (In January we actually issued a report on 21 public buildings ). 

One of the biggest issues is getting access to the actual data - many clients don't want to share.

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).

For those of you not in the NE part of the country,... Read more

The Sustainable Design Leaders group has had awesome, inspiring Summits for ten years now—and there is so much more we can do can to make it a thriving, essential year-round community. To do that we have to extend the trusted “safe space” of the Summits into our online conversations.

And other groups are just getting started on a... Read more

Hello SCL members,

A gaping hole has been left since Patty Lloyd stepped down from our SCL steering committee. Don't worry, she is still in the network and tirelessly championing SCL. But this means we are opening up nominations for at least one leadership spot. If you are interested, please email me directly (candace@buildinggreen.com)... Read more

The Building Decarbonization Practice Guide is extremely helpful but, from their comments, it is all coming... Read more
