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.

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

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...

Hi all,

I'm wondering if you all have had a meetup at NESEA's Building Energy Boston conference before? Is anyone interested in meeting up this year? I'm open to ideas! If you give me your email address I can attempt to organize an informal meet up on one of the conference days.

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