A number of very well-known green buildings rely on ice-based TES cooling. One of the newest such buildings is the 2.1-million square-foot (195,000 m2) Bank of America building in New York City at One Bryant Park. I visited the sub-basement (three floors down) to see the 44 eight-foot-diameter, insulated CALMAC tanks in the building that collectively provide about a quarter of the building's cooling. Each of these tanks holds about 1,600 gallons of water that is alternately frozen and thawed by circulating a glycol solution through about three miles of plastic tubing. It's high-tech, but the result is surprisingly simple.

Benefits of ice-based TES include the following:

BuildingGreen's Michael Wentz has been coordinating for some time with DOE on case studies of the green rebuilding of Greensburg, Kansas, which had 90% of its buildings destroyed by a tornado in 2007. He described the work in a blog post here last year. Then, in a congressional address last February, President Obama cited Greensburg as "a global example of how clean energy can power an entire community," to which Michael added, "they are also a leader in green building including initiatives to work green building strategies into their building codes."

A compelling hour-long documentary about what happened in Greensburg and the community's subsequent decision-making process in the wake of the two-mile-wide, F5 tornado is available to watch over the web.

ICFs (Insulating Concrete Forms) are permanent, stay-in-place forms for making insulated poured-concrete walls, floors, and roof decks.

Most of them are made with expanded polystyrene (EPS) foam produced with a non-ozone-depleting blowing agent (unlike XPS, an option to avoid from some manufacturers), while others are made with EPS beads (typically from recycled sources) or mineralized recycled wood chips glued together with portland cement.

Generally, the pure-foam sort are direct replacements for standard removable forms and are used to make regular, flat poured-concrete walls with an equal amount of insulation on both sides; while the cement-bonded foam-bead or wood-chip type usually have voids that get filled with concrete to make structural grids, columns, or "waffles" encased in insulation. This is usually the way it is; there's some overlap and variation.

From here on, it gets tricky and sticky.

The EcoDorm at Warren Wilson College houses 36 students who are interested in environmental responsibility and want to live with like-minded students. The co-ed dormitory is one of a series of four dorms surrounding a common lawn.

Warren Wilson College is an independent, accredited, four-year liberal arts college in rural North Carolina. The school's mission statement includes a dedication to environmental responsibility, and environmental literacy plays a significant role in the curriculum.

The Lacks Cancer Center, the only dedicated comprehensive cancer center in western Michigan, supports all components of cancer care, including inpatient and outpatient care and traditional and complementary therapies.

The building houses 42 private patient rooms, expansion space for 42 additional rooms, family hospitality spaces, treatment spaces, surgical suites, outpatient services, healing gardens, sheltered promenades, a chapel, and a resource library.

The University of Denver's College of Law houses one of the nation's top environmental and natural resource law programs. The first LEED-certified law school in the nation, the facility offered the College an opportunity to design a building consistent with its mission: a green facility that reduces environmental impact and prioritizes occupant safety. The new 210,000 ft2, four-floor facility, constructed on a former parking lot, includes a library, large lecture halls, training courtrooms, a dining hall, and faculty offices.

Recently, I broke one of my long-standing rules and blogged about something BuildingGreen-related at my own blog. My Costanzian fears were indeed warranted, and I've been egged on to cross-post it to the Live blog. Here she is, warts and all: my unvarnished opinion on the very best parts of the BuildingGreen product GreenBuildingAdvisor.com./BF

I don't often blog about worky stuff here, but decided this week that my "Worlds Will Collide!" fears are probably completely unwarranted. Besides, I'm working on some cool stuff these days. And finally, when my wife asks me, "What have you been doing?," when I come to bed at an obscene hour, I have an acceptable answer: "Changing the world, baby. Changing the world."

BuildingGreen launched a new property several months ago, GreenBuildingAdvisor.com (GBA). Now, this was in process as I came into the company in September 2008 and involved a whole lot of organization and reorganization to get the team in place for even content production, but I can't get into much of that here. What I *CAN* get into are what I think are the absolute coolest content areas on this Drupal-based site.

Green Basics

It's really important to come at a new field with a common vocabulary. Think of this as a vocab-building primer of terms and concepts bandied about in Green but seldom explained or contextualized. Click anywhere on that page and you get access to detail diagrams and explanations of key concepts and terms. I subscribe to a couple of building magazines and use their sites a lot. NOTHING is as good as this, period.

Green Homes

Now, case studies are not something new for BuildingGreen given the popularity of the High Performance Buildings Database, but there's one aspect in the corresponding Green Homes feature area that stands out: these pictures are gorgeous and inspiring. Sure, I can look up a product if I hear about and learn enough to put it in myself... but watching it get installed? Or seeing it in a context that gives me another product idea?? Reading about the compromises that lead to selection of that product in tandem with another? That's pretty awesome.

Product Guide

The Product Guide is some content syndication from GreenSpec, another key BuildingGreen property that provides a ready-to-use index of green products, manufacturers, and product categories. They sum it up on the GBA page with this: "Product manufacturers can not buy their way on to this list." These are a true best-of and where I first turned for ideas when we did our kitchen remodel this year.

Summary

Now, I know I've probably alienated some portion of the site that's behind the payed membership wall (oh yeah, some of this content is part of a paid GBA Pro membership that gets you even more like CAD Details & whatnot), but these are the stand-outs from my perspective and key to what makes this site a truly amazing asset. At the time of this writing, you can get a 10-day trial to the premium GBA Pro content - the energy savings I've realized alone have outvalued the cost of this annual or monthly membership - or be a lurker for a while before you take the plunge. Personally, I'm probably not renewing some of those magazines whose sites I use in favor of this totally righteous tool.

This morning, at 33rd St and 7th Ave in the middle of New York City — right outside of Madison Square Garden and Penn Station — a 70-foot-tall digital billboard displaying a real-time running total of atmospheric greenouse gases was unveiled. The display reflects a measurement of 24 long-lived greenhouse gases (not including ozone and aerosols) named in the Kyoto and Montreal Protocols, and is based on Massachusetts Institute of Technology (MIT) research. The Carbon Counter is part of a "Know the Number" awareness and education campaign by Deutsche Bank's institutional climate change investment and research business, the DB Climate Change Advisors group (DBCCA).

In a press release, MIT Professor of Atmospheric Science Ronald Prinn is quote as saying:

"It is useful to have an up-to-date estimate of a single integrating number expressing the trends in the long-lived greenhouse gases contributing to that change. This number can help convey how fast these greenhouse gases are increasing, and the progress, or lack thereof, in slowing the rate of increase. The number on the Counter is based on global measurements. It shows the total estimated tonnage of these gases expressed as their equivalent amounts of carbon dioxide, with seasonal and other natural cyclical variations removed to more clearly reveal the underlying long term trends driven by human and other activity."

The carbon footprint of the billboard, which includes nearly 41,000 LEDs, is offset using carbon credits.

As a company, Deutsche Bank is working to reduce its carbon emissions annually by 20%, with a goal of carbon-neutrality from 2013. Carbon credits? RECs? It's still noteworthy and praiseworthy. How does your company compare?

The Carbon Counter Number is also available anytime at www.know-the-number.com — or right on your own computer via a free downloadable widget.
