Metal windows are used in commercial building because of their durability, low maintenance, and ability to handle wind loads.

BuildingGreen-Approved Windows

Metal windows must achieve an NFRC-certified unit U-factor of 0.20 or lower to be approved by BuildingGreen.

Manufacturers also must demonstrate that their highest-... Read more

I've been hearing a lot of talk about density becoming a thing of the past. Like with the danger of antimicrobials, it would be great to have some more in depth backup information on whether density is really a danger factor, or if other factors are more important, when we go into these conversations. Does anybody have any new or better... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

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

What better way to follow up the magic of a live presentation from Peter Yost than with 30 free days of BuildingGreen Premium?

All--

I haven't been part of this group in a while, but I'm excited to have rejoined recently. Some of you know that I joined HMC last year as Chief Impact Officer. I oversee design, sustainability, research, and communications for the firm, which has 300 people in 6 offices in California. We were founded in 1940 with a mission to serve... Read more

The LBC v4.0 materials imperatives for Responsible Materials (Core) & Responsible Sourcing require a majority of wood materials (by cost) to be FSC. Sure. But what is - or isn't - considered wood? The Clarification page for the imperative's scope and a key definition poses a perplexing conundrum: 

"All wood included in the Materials... Read more

What a great first day!

Here are the slides from the show and tell presentations last night at SOM's office; everyone who presented with slides has given approval to share them.

What is your favorite, tangible example of an EUI?

I find it easy for individuals to undervalue the power of a single EUI and curious what useful parallel the creative folks in this forum have used to illiterate its compounding value?

Cheers!

Hello all,

Does anybody know of a substitute for Ecotect's solar tool? I use it to very quickly test shade options and I love how I can easily test horizontal and vertical elements, tilting and rotating them. I can have a window with the façade on one side and the sun path with the shadow mask on the other side. It is easy to use and... Read more

Hi Everyone! 

I am building our internal/firm resources around sustainable design, and creating our post-occupancy evaluations is one of those resources. Does anyone have references or resources they'd recommend me to look into for post-occupancy evaluations? So far I am considering a few evalutation types: building user input, building... Read more

Looking for a recommendation for architectural renderings who would be interested in doing some work for a Direct Air Capture project. A friend is working on a project with Deep Sky and I'd love to make a connection to someone(s) affiliated with the network, if possible.

Hi all,

We are in the process of pursuing the Integrative Process for Health Promotion pilot credit on a project. Has anyone been through the process? What did you learn? How did it change/inform your design? Would you do it again?

Thanks!

Michelle

Hi: SD Leaders.  It was so nice to see so many of you at Greenbuild in Chicago. By now I'm sure all have seen the announcement of the release of the Fourth National Climate Assessment Report vol 2.

Hey Gurus:

I have a client who is interested in reporting to their superiors on the status on energy codes in different states across the US. They are hoping to find some kind of summary that might show relative costs for HVAC systems under the various energy codes in effect across states. They are also interested in data that is...
