Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Glazing connects occupants to the outdoors, but with so many opportunities for air leakage, poor insulation, and thermal bridging, glazing is the primary weak link in building energy performance.

BuildingGreen approves glazing that offers strong energy performance properties for a variety of... Read more

Hi All, this is primarily directed at our Sustainable MEP folks, but please anyone with insight feel free to weigh in.

I am increasingly seeing designs and specifications asking for Passive House levels of airtightness as verified by blower door testing, but with traditional ventilation system designs. 

To me, Passive House US has... Read more

Hi everyone! I saw that BuildingGreen won't be faciliating a meet-up in Atlanta but are there any other peers attending Living Future next week and want to self-organize? If we can find a venue - i wonder if there are any locals on this list with a recommendation? Could do Wednesday 7-8:30 between the two scheduled reception and after-hours... Read more

Team,

See link above, a group of UK building services (MEP) engineers (like us) signed on above, committed to do life cycle carbon (including embodied MEP) in their work.

Are we behind?  Should we match them?  leap frog ahead of them?

Best,

Has anyone developed a disclaimer to be issued with LCA models and reports? I have been asked to look into developing a disclaimer to be used with LCAs, and unfortuantely I have not been able to find past precedence on this. 

Thank you,

Hi all-

We are dabbling in developing an official research component of our firm. We have collaborated with a class at a local university and are looking for ways to take our research to a higher level. I'm curious how some of the other firms doing design or building technology research approach the process. For instance, do you have a... Read more

Hi folks,

Our regular SMEPLeaders call is next Tuesday, Sept 12 at 2:00 eastern (if you don't have this on your calendar, let us know and we'll resend the invite).

We've had a GREAT run of meetings that kicked off with someone sharing on a topic they're excited about or challenged by. The conversations that follow that kind of... Read more

I am diving back into Sefaira for the first time in a while, and the program still seems to be missing the ability to account for automatic daylight dimming in energy savings. Previously I had used an LPD reduction equivalent to emulate the savings automatic dimming would provide. Has anyone done a similar work-around? 

Hi all,

Just wanted to put a couple of useful webinars on your radars if you haven't heard of them yet:

#1: The Contractor’s Role in Quantifying and Reducing Embodied Carbon: Why, What and How

This webinar will provide an overview of what a contractor's role is towards embodied carbon reductions, and how two General... Read more

Hello SCL members,

We’re anticipating wanting a few more people to serve on the SCL steering committee and would like to open the process up for self-nominations. If you are interested, please email me directly (candace@buildinggreen.com) by Nov 5th.

The Steering Committee meets monthly and serves the important role of helping... Read more

All,

I think there may be more than a few people interested in an article I co-authored titled Comparative whole building life cycle assessment of renovation and new construction. It is now available in the journal Building and Environment. Fortunately we have a link that gets you past the paywall that is good for 50 days. If you have... Read more

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more
