I can hear Kjell saying "All models are wrong, but some are useful." Having said that we are having trouble getting usuable predictive energy use information from our electrical design engineer. They are telling us that their energy models are not for accurate pEUIs but just to compare various scenarios. Are they being lazy? Should we push for... Read more

HI All,

I am curious if others are using THERM in-house for your envelope design?

We usually use our building envelope/curtain wall consultants (Boston - so mostly RWDI and Heintjes) but our teams are finding that they need the information faster than our consultants can provide, they are backlogged, or we have some curtain wall... Read more

Hi All,

USGBC MA is doing a study on the cost of net zero energy buildings in MA.  I’m wondering if you all have any data to share on plug loads in ZNE projects. I’m looking for single family res, 2-4 unit residential, +/- 60 unit residential, 10-12 story office, and k-12.  The engineers have presented initial results and their... Read more

Hi! Over the last 10 years, the firm where I work in Boston has predominately designed housing & senior living projects in the the Boston Metro region, with the occassional project in NH, CT, RI, and NY. We have built projects as far south at DC, but never designed anything to my knowledge in California in our 55 years of operation. A... Read more

This is something I have been tracking since last year. The same or similar bill was introduced in 2022 but failed by one vote. This would mandate carbon reporting for any company with revenue of $1B or more AND which does business in California. Unlike the upcoming SEC reporting requirements, this would apply to both private and public... Read more

I had a brief text exchange with her on Saturday 28 September, and I feel sure that she would be OK with my sharing it with you all:

Hi all - 

I have heard a good deal about SBTI in the last while and am wondering about this group’s firms’ engagement with them. We reported one year through CDP, and it was not very useful. It focused entirely on Scope 1 and 2 emissions, which are over 1000x times less than our semi-controllable Scope 3 (buildings’ embodied carbon and... Read more
