Chillers are part of larger systems that provide cooling in large commercial buildings.

BuildingGreen-Approved Water Chillers

Because there isn't a single relevant efficiency standard for chillers, approved products use innovations such as magnetic bearings, variable frequency drives, or other technologies that significantly... Read more

Hi folks,

Here's a neat resource that just showed up. Pages 5-7 list exactly what kinds of activities could be covered by new federal funds, and what part of the legislation relates to each activity...

HI MEP Leaders,

Related to our thread about equipment needed for decarbonization, I have a question about what new or improved equipment is already available now that you're excited about.

Every year we at BuildingGreen publish (and present at Greenbuild) a listing of the Top-10 new and exciting products. Our focus this year is on... Read more

SDL Group -

Hi all!  After a brief hiatus from the group to move from New Orleans to Portland (OR), start a new job at ZGF Architects, buy a house, and  see my baby boy become a toddler (all in the past year!)---- I'm ready to plug back into the group.  Seeing folks at the ILFI conference re-energized me to reengage :)

So…..does... Read more

Were we given any warning that LEED Online and USGBC.org would be down for a week?  

I had a client ask recently if there is a 'better' global social justice tool than ILFI's JUST for use outside the U.S. 

Personally, I'd look to WELLv2 feature C12 - Organizational Transparency for other options... but personally have very limited knowledge of options c-e.

Do folks have an opinion on if any of these prograams are... Read more

Hi All, 

My understanding is that SCL reporting is only for refrigerant use, or recharging for headquarters. I've asked our MEP contractor for a list of our 21 units, refrigerant use, and what quantity of refrigerants were used to charge equipment during installation or service.  

Is anyone tracking this for job sites?... Read more

How much will it cost to achieve LEED v4 certification?

“We’d love a green building, but can we afford it?”

“We’re required to be LEED Silver, but we’re not sure how to get there under the new rating system.”

“Sure, we’re interested in LEED, as long as it doesn’t cost extra.”

LEED v4 and cost uncertainty

Hello Green Gurus,

Back at the retreat in March 2021 (does anyone remember back that far?), we formed an Air Quality Working Group with members from SDL, SMEPL, and SCL. Drawing on our collective experience, standards, research, and other resources, we began navigating the murkiness of indoor air quality considerations. We came up with a... Read more

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

It may take hundreds or thousands of years to return to pre-industrial-age levels of atmospheric carbon dioxide, but the loss of animal and plant species that is occurring today is, practically speaking, irreversible. It will take millions of years for evolution to fill the ecological niches being vacated by extinctions and restore healthy... Read more

Hi all,

We have a newly constructed, core/shell project having some hot water issues in the core restrooms.

There is a 0.35 Toto lav installed throughout. The hot water heaters are adjacent on each floor, located in the janitor closets. We did the math, and there could be a gallon of water standing and cooling in the pipe between... Read more

Hello,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

Hi everyone,

Have your projects explored, pursued, or successfully achieved the domestic content bonus for PV systems within the Inflation Reduction Act (IRA) Investment Tax Credit? I have a project that is considering adding the IRA domestic content requirements and we are trying to understand the nuances and potential challenges (cost... Read more

Hello all,

This month's SCDL call was full of great discussion! We decided this month that we are feeling good about where we are for the Task Force Agreement on defining social sustainabiltiy in our work. The aim is to work with this agreement for a while and see if it holds up as a process framework. There was also interest to invite... Read more
