Help. I have a contractor in need of advice on IAQ testing agencies and I'm largely uninformed about the local market of IAQ testing agencies. Anyone have organizations they'd specifically recommend or not recommend?

Feel free to email me directly if you'd prefer - awilson@ayerssaintgross.com.

I posted this a while back on the MEP SDL forum but also wanted to appeal to the broader community.  We need help gathering existing plug/process load data.  We know it is out there!  Two golden stars to Becky Alexander from LHB who reached out to us after this month's meet-up with some useful material.  We need more!  Please...

We're consolidating our office and I find I have back issues of EBN going back to 1999 on the bookshelf. Any use for these other than compost?

Does having a rating system change the conversation? How well defined are the metrics for resilience? How to measure success? Does the RELi Rating System provide a good way to define resilience. How many are using the system and have they noticed a growing level of understanding because there is a rating system? How to talk to clients about it?... Read more

Hi,

Has anyone been asked by a client to track welding rods on any projects? We were recently asked to do this. I was asked why the client would ask us to do this. I don't know if it has to do w/ "real property" and is a property tax-related reason, or if it is an environmental/sustainable reason. There is piping associated with the... Read more

Have any of you heard of anyone ever using phase change material (PCM) "movable partitions" as a resiliency strategy to mitigate indoor overheating during a heat wave in passive buildings? You'd keep them stored in a basement or cool room, and deploy them into habitable spaces during the heat wave to keep the space cooler than the exterior... Read more

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
