I have a question on the previous slide..
John Bolduc
01:08:37
You would be able to check energy and emissions performance thru Boston's Building Energy Reporting and Disclosure Ordinance. They would have to report annually.
Bob Beinstein
01:10:05
This issue of performance monitoring over time is a thorny one. Anyone have cost:benefit data for such activities post-certification? This data could be instructive for Envision as well.
Jim Grant
01:11:41
Building HVAC systems can lose up to 3% per year efficiency if not maintain. That is where Measurement and Verification services comes in, i.e., continuous commissioning.
Vincent Guimont Hebert
01:12:23
The challenge with LEED-type certification program, is that they are mostly qualitative, and they don't integrate a weighting scheme on credits that are material (energy consumption in this arena case).
Bob Beinstein
01:12:44
Jim, do you guys do that? Are owners interested/willing to pay for it? And, how do you quantify the benefit to the owner?
Aladdine Joroff
01:13:28
It raises interesting legal questions too for building owners who have contracted for a "net zero" or other type of building which may meet the performance standard when built but not when operated.
Bob Beinstein
01:18:03
Interesting Aladdine. Can that form a financial driver for the kinds of continuous commissioning services to which Jim referred?
Aladdine Joroff
01:22:37
Bob, I could see continuous commissioning becoming a contract condition to protect a builder; perhaps along with limitations on changes in use of the building.
Bob Beinstein
01:26:21
Very interesting aspect, Aladdine. I also could see that condition, adding that it may be an incentive for tenants, giving certainty that savings will be realized. Downsides could be: what remedies occur if the performance downgrades, and, limitations on use changes may tie an owner's hands as markets evolve. Lots of work to do in this space for sure!
Aladdine Joroff
01:28:23
Bob - agree, lots of permutations to consider! I think a significant change of use could "relieve" a building developer from having to meet the building performance standards that were promised at construction or for a specific use. Or at least shift the portion of liability for any chance in noncompliance.
John Bolduc
01:30:04
I think the next iteration of BHFRM will look worse in terms of flood risks.
Vincent Guimont Hebert
01:49:30
Funny fact: The beet juice used to melt ice (that we saw rapidly in John's slide) is an amazing innovation that paid off big in terms of ROI but also reducing the effect of salt on the structure (concrete/steel) and the river ecosystem below.
