Hello Everyone!

Wondering if anyone has expertise in Algae Photobioreactor facades? Here is a product: https://cellparc.com/

My basic understanding is that they produce heat and biogas (as well as providing shade and some thermal value.)  However, I am not clear on the GHG balance benefit, so to speak.  I cannot determine if the... Read more

Hi all,

I'm curious if anyone has insight as to the "New Federal Building Performance Standards" that were announced in May of 2021 and then referenced again when E.O. 14057 came out. The memorandum for heads of agencies that was sent out with E.O. 14057 said that the CEQ would issue these standards, but I can't find a commitment to when... Read more

Looking for an example or case study for a building utilizing a radiant heating/cooling in climate zone 4a. General use type is office with some public assembly spaces, total of 85,000 sf.

As usual, everyone, especially mechanical engineer, is terrified by the thought of "condensation." So far, I read a DGWW case study, "Energy... Read more

Split systems are multi-component units that use an outdoor condenser along with separate indoor fan coils to move refrigerant—and provide heating and cooling—in buildings without the need for ducts.

BuildingGreen-Approved Systems

BuildingGreen approves mini-splits that are tested to AHRI standards and have minimum SEER and an... Read more

Hello all, 

Any Fitwel experts out there? I have a 30,000 sf boutique hotel + spa client who would like to certify under the Fitwel rating system but Fitwel folks are telling me that no scorecard is currently available to hotel clients (can't use mulit-tenant or resi, that a hotel scorecard is under development). Has anyone used Fitwel... Read more

Hi friends,

We recently tracked our water consumption on site during the structural demolition of some existing reinforced concrete buildings.  The new OSHA silica regulations required us to keep dust to virtually zero, so we had a bunch of mist cannons and water hoses pumping water around the clock.  We consumed ~855,000 gallons in a...

We have a client who is asking us to design a roughly 10 ksf Wellness Center for PHIUS 2021 certification.  The program includes several high density assembly type spaces - roughly 300 person peak occupant load for the building.  The Criteria Calculator that the architect showed us puts the building peak cooling load at 4 BTUH/sf (3000 sf/ton...

I've written waste and recycling policies many a time before for both construciton and operations... but in a volunteer committee application this morning, the maintenance team got bogged down on "how do we collect recycling without plastic bags" question. I told them there's not any kind of plastic bag that I'm aware of which can be thrown... Read more

Hey, everyone! Reaching out to share about the currently-under-development IEA Annex 89: Ways to Implement Net-zero Whole Life Carbon Buildings. The current committee is really the who's who of building LCA in Europe, but it does seem like it suffers from a lack of North American representation. The one North American on the committee, in fact... Read more
