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

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

If you haven't seen it yet, today's U.N. report "Making Peace With Nature" tackles climate change, biodiversity loss, and pollution jointly within the framework of the Sustainable Development Goals. 

The analysis is anchored in current economic, social and ecological reality and framed by economics and the 2030 Agenda for Sustainable... Read more

What is the lag time for historical embodied carbon data catching up with real-time information as manufacturers source renewable energy? Is our professional time best spent calculating with out-of-date information or more simply calling for manufacturers' elimination of fossil fuel combustion in their production and transportation of materials...

In our quest to create a low carbon future the lectrification/Decarbonization working group is planning spend the next 10 months creating tools to advocate for electrification:

Is there a list of which number corresponds with each Best Practice? E.g. "03 Energy Audit & Planning."

Huge shout out to Patty Lloyd, Luke Leung, Janet Olsen, and Sarah Gudeman for their webinar on the Power of Peer Networks. They share lots of insights into the value of participating in BG Peer Networks and many others. Ten bucks to Illinois Green gets you access to the recording--I loved it. What would you have said that they didn't?

Hi,

I have a colleague doing research on PCM in several projects. For context in their report, they were wondering if this group has seen any recent increase in application of PCMs in recent years. Is it just in ceilings or other applications? If so, what products are being used? They were having difficulty finding manufacturers other... Read more

Happy Friday, SDL!

We're running a Tally WBLCA for an environmental education center, which has a very small floor area but a fairly robust concrete/steel structure. Still, I was surprised to find an intensity of over 1,000 kgCO2/m2 for the building.

This is way higher than the general benchmarks I've found in the CLF's database,... Read more

Typically made from petrochemicals, carpet and its adhesives can offgas. It is also a challenge to recycle them, increasing the chances that it will be incinerated or disposed of in a landfill. Because carpet has a limited lifespan, its life-cycle performance is key.

BuildingGreen recommends modular carpet that demonstrates lower life-... Read more
