Green buildings: shooting for the stars or arriving at average?

Thursday, July 23rd, 2009

What is the purpose of a new green building aesthetically? Should it look like every other energy hog on the block? Or should it look different to call attention to the fact that it’s special?

That’s what I’m wondering after your comments to the post below, regarding the new LEED platinum headquarters building for the U.S. Green Building Council. Holz says “it’s got no soul,” while a conversation between Nate and I revolved around the image that the USGBC is trying to project. Nate says “USGBCs goal seems to be to bring green to the mainstream, and thus it is not surprising that they wanted their office building to look like a traditional office building.”

But why go traditional when you can go exciting?

I don’t even work in the field and I can come up with a number of reasons. It’s less of a risk if you design something that looks like everything else. And while many people might think the idea of LEED is great, there are also people out there who think it’s a load of hogwash. And heck, if you’re standing in a standard-looking building, you’ve got to search out the single USGBC plaque and know what it means before realizing you’re in a green building. What percentage of the population would even recognize the seal if they saw it?

But if you’ve got a green building that’s obviously a green building from its architecture, who knows how it will be accepted? Who knows if people will like it, or if tenants will choose it over a more common counterpart. It’s also more obvious to nay-sayers that the people who developed the building - and use it- are committed to green practices (or at least want to appear that they are).

Then again, one has to assume that if you’re going to the USGBC’s offices, you know that the people you’re about to be speaking with are green-minded.

And if the envelope is never pushed, you won’t get buildings like this:

or Nate’s favorite:

CK Choi Building for the Institute of Asian Reserach by Matsuzaki Architects

or possibly the first living building in the country….

The Omega Center for Sustainable Living by BNIM Architects

Or the LEED gold Environmental Protection Agency Region 8 headquarters in Denver. From the outside…

And from the inside

Though to be fair, all the above photos are of buildings for private institutions or agencies that don’t really have to worry about market forces.

What do you think? Should really green buildings look like everything else or do they need to look mainstream for reasons of marketability, etc.? Answer my poll at right or share your thoughts below.

And if I missed a great example of a green building that pushes the aesthetic envelope, please comment with a link to a photo of it…..

Photos of Seattle’s largest green roof at the Gates Foundation garage

Monday, March 2nd, 2009

About a month ago (Jan. 20) I wrote a story in the DJC on the green roof at the Gates Foundation’s garage. At 60,000 square feet or about 1.4 acres, it is the largest green roof in Seattle by a landslide.

The garage is a crosswalk away from Seattle Center on the east side of Fifth Avenue North. It is located next to the future Gates Foundation headquarters and is kitty-corner from EMP. The garage is technically a public-private partnership between the Gates Foundation and the city of Seattle. NBBJ was the architect. Sellen Construction was general contractor. Gustafson Guthrie Nichol was landscape architect.

The roof itself is visible from the Space Needle, a consideration in its design. The roof has five inches of soil over a layer of synthetic drainage. 

Here are photos:

A side view photo only begins to show how massive the roof really is

Pictures of the green roof at Olive 8

Thursday, January 8th, 2009

The green roof at Seattle hotel-condo project Olive 8 is being installed this week. It is one of the largest green roofs in Seattle at 8,355 square feet.

The roof is actually two green roofs so the developer, R.C. Hedreen, can test out which system it likes best. Above the chillers there is a sod-based green roof. On the actual fourth floor ground level, there is a tray-based sedum system. There is a lasting argument between which one of these techniques is better, which I will discuss in a later post at greater detail. For more on this project, or to learn about R.C. Hedreen’s conversion to being a green developer, read the story in the DJC here.

R.C. Hedreen is also considering a second green roof on the 39th floor of Olive 8, though if it pursues that option it will need to be sod-based as David Thyer, president of the company, said the city is afraid the green roof trays will blow away at such a great height.

On Tuesday, I was fortunate enough to see part of the tray installation. Here are photos I took of the process:
