Take look at the “world’s greenest office tower”



Tom Paladino’s company was on the design team for the Tower at PNC in Pittsburgh and he says the project changed his life.

The Tower at PNC in Pittsburgh is being billed as the greenest office tower in the world. It has a skin that breaths, a solar chimney, a park in the sky, wood-clad porch doors, indicators that tell you what the weather is outside, and something called The Beacon – an interactive light sculpture that broadcasts data about how much energy the building is using.

The tower is shifted on the podium and street grid for maximum sun exposure.  A double-walled “breathable” facade provides a thermal buffer while allowing air to pass through.

So what’s a solar chimney? It’s a vertical shaft with a rooftop solar collection panel that creates an updraft that draws cool outside air through the skin, across the floors, and up and out of the building, without requiring fans, for almost half the year.

A “living room” space links every two floors of the building, and a five-story indoor park offers views of downtown Pittsburgh.

Paladino acted as owner’s representative on sustainability and LEED management issues.  The 800,000-square-foot, 33-story building was designed by Gensler to reflect PNC’s commitment to green building, energy efficiency and innovation.

The design and systems will help reduce energy consumption by 50 percent and reduce water use by 77 percent compared with a typical office building, Paladino said.

“It was ridiculously simple, and at the same time,  a challenge in its aspiration,” said Tom Paladino in his blog post on the tower.

“LEED shifted from being the purpose of the green building program to being one of the desired results. We moved to a higher purpose, creating a headquarters that would serve PNC as another tool of the business.”

The building was designed to be “the most progressive workplace ever and to attract a highly social, digitally native, and an environmentally conscious work force,” Paladino said.

The Tower at PNC is built green for future generations to enjoy.

The tower cost $400 million.

Transparency: the new mantra

The following post is by Kathleen O’Brien:

Ten years ago when Alistair Jackson (now principal of O’Brien & Company) and Michelle Long (now Executive Director of BALLE) created the Transparency Institute, they just couldn’t gain traction they wanted and needed to make a go of it. “We were ten years ahead of our time,” Jackson sighs.  Now, transparency is all the rage. In fact, at GreenBuild recently, I couldn’t walk five feet without some reference to the concept.  Most references were focused on product transparency, but not all.  At the International Living Future Institute’s GreenBuild Booth, the nonprofit was touting its new “JUST” Label, which applies to organizations transparency.  Organizations of all types and sizes can earn the JUST label when they are willing to report on 22 social and equity indicators related to six categories: diversity, equity, safety, worker benefit, local benefit and stewardship. The JUST Label joins the organization’s DECLARE, a “nutrition” label of sorts for building products.

JUST is a voluntary disclosure program where organizations can report on their workplace equity policies and practices.

DECLARE is one of the latest efforts over the past decade to make it easier for building project teams to “do the right thing” when selecting products and technologies. Product certifications, such as those offered by the Carpet & Rug Industry Institute (focused on VOC emissions) and Forest Stewardship Council SC (focused on sustainably harvested wood products) have been one way to achieve this goal; but even there, industry members have been demanding more transparency, wanting to know what’s behind the “green” label.  DECLARE requires that manufacturers complete a Health Product Declaration (HPD) that is then publicly available.  The hope is that this label will make it easier for project teams to use the Living Building Challenge, which “red lists” materials and chemicals the ILFI deems hazardous.

Eden Brukman, Technical Director for the non-profit HPD Collaborative was staffing its booth at GreenBuild, where business was non-stop.  Brukman noted a “remarkable uptick in interest in (HPD’s) work.”  The Transparency Movement (as some like to call it) is definitely experiencing an upswing, and HPD is clearly a key player in this progression.  In addition to offering manufacturers an open standard format for reporting product content and associated health information for building products and materials,  the service is free for all to use, which is certainly one factor in its gaining popularity.

The HPD Collaborative partners with several product databases.  Green Spec was one of the first independent efforts to vet and list products meeting specific requirements.  The Pharos Building Library provides access to HPDs (as do most of the other collaborative members)  as well as a full assessment of health hazards associated with the product and its manufacture, VOC certifications, renewable material content, and renewable energy usage. SpecSimple is more recent, and unlike Green Spec or Pharos, includes advertising.  Another commercial database partnering with HPD includes Green Wizard, which integrates its product library with a proprietary software aligned with LEED credits (WORKflow Pro). I understand from one user that the software program is “pricey” but a good value. GPD’s THESource (which also offers advertising) aligns product transparency efforts with BIM and Revit; I attended a GreenBuild presentation introducing  GPDTools (Alpha), a free downloadable add-in specifically designed for the Autodesk Revit users to search, select and annotate building product data (including HPDs) directly.

Transparency has become a byword in the green building industry, where members are demanding to know more about the contents of the building products they use.

Nearly 30 manufacturers at GreenBuild were exhibiting products that are Cradle to Cradle Certified.  Up to recently a proprietary system closely held by its founders William McDonough and Michael Braungart, the Certification has gone public with the founding of the Cradle to Cradle Products Innovation Institute.  Lots of other product certifications were on display as well — sometimes several for the same product. One GreenBuild attendee complained that the multiple certifications on many product booths were confusing, but my guess is that as the drive for transparency takes hold, two things will  happen, the value of a given certification will be understood more clearly, resulting in a more nuanced weighting of that certification in the prospective purchaser’s mind.  Another consideration is the audience for the certification(s): a skilled professional whose license depends on being informed, and the less informed consumer of the skilled professional’s services.  My observation, at least at events like GreenBuild, is that professionals are seeking more information, not less. But they want to know the information they are getting is good quality — and transparency can help them know that.

Transparency is not intended, however, to sort out the certification puzzle. The commonly held view is that manufacturers won’t want to reveal damaging information, such as the fact that a given product includes harmful ingredients or was created using harmful processes.  Forward-thinking companies with solid product portfolios (or willing to create them) have done the calculus. This is good for business. Laggards will innovate or lose in the race for transparency.

Kathleen O’Brien is a long time advocate for green building and sustainable development and most well known for founding O’Brien & Company, the oldest green building consultancy in the Seattle area.  She lives in a green home, and drives a hybrid when she drives at all. After 30 years of working in the field, she is now focused on providing leadership training and mentoring through her legacy project: The Emerge Leadership Project, a 501c3 non-profit with a mission to “accelerate life-sustaining solutions in the built environment through emergent leadership principles.”

Greenbuild recap: Seattle represented!

GreenBuild is done for another year. Looking back, I can definitely say the Pacific Northwest – and Seattle in particular – represented.

From speakers (there were at least 35 from the Pacific Northwest) to people in the crowd (I must have seen at least 50 people from the area) to a reference in Rick Fedrizzi’s opening speech to the Living Building Challenge to expo hall presenters, there was a giant contingent representing what

some *ahem* consider to be the greenest region of the country.

Overall, I noticed a change in GreenBuild presenters. It seemed (to me) that there was a little less architectural focus and more focus on the financial aspect of green building from the real estate side. Speakers came from Kennedy Associates, Wright Runstad & Co., Hines, PNC Real Estate, Lease Crutcher Lewis, Vulcan, Jones Lang LaSalle etc. To me, this reinforced the idea that “green” is becoming more and more mainstream. While the design aspect is important, the financial metrics really sell it — just look at LEED volume. I also noticed a focus on the sustainability of the site, versus just the sustainability of the building.

I enjoyed the focus of the expo floor to reduce waste. Instead of a flood of literature that stays on my desk for months, presenters were encouraged to limit waste and only give away business cards. It was impressive.

I also enjoyed some of the wild outfits that turned up. Especially colorful cowboy hats, a full fake animal print suit in different colors and the myriad of cowboy boots worn on people’s feet. A friend of mine said there seemed to be a lot more suits at GreenBuild this year – which she said is a good thing “cuz we need ’em!”

As for dislikes, I heard a lot of complaints about the lack of vegetarian food (this is GreenBuild afterall!) I also heard a lot of people complaining about two elements of Colin Powell’s speech: his discussion of the state of terrorism in the U.S. and abroad and his statement that coal, nuclear and oil need to be just as much a part of our energy portfolio as solar and wind energy.

What did you think of GreenBuild? Comment below and tell me what your favorite – or least favorite part was. Would love to hear your reaction!

GreenBuild Day 2: bifacial solar panels and natural swimming pools that use plants, not chlorine!

I’ve been through about an eighth of the GreenBuild Exhibition floor so far and wanted to share two of the things I’ve seen with you.

These are the Sanyo bifacial panels that will be on the Bullitt Foundation’s Living Building on Capitol Hill. The collect energy from both sides while letting some light in at the same time. Bullitt was attracted by the transparency of the panel.

And this is the BioNova Natural Swimming Pool. The swimming pools use natural systems (meaning plants in gravel) instead of chlorine and other chemicals to treat water. That means the water color is darker, looking more like a lake than a traditional pool. It also means that people that use them need to get used to the idea of sharing their pool occasionally with frogs or other critters. James Robyn, CEO of the company, said the pools aren’t for everybody. “Whoever doesn’t like that sort of thing shouldn’t do this.”


Robyn said the pool technology came from Europe, where it has been used for 20 years. He said it has a low carbon footprint, is all natural and is “perfectly healthy.” Robyn, who is based in New Jersey, said he’s being asked about the pool system all across the country. In fact, he was in Seattle giving a lecture last month though he said there are not yet any of his pools in process in the Seattle area.

There are basically five ways to build the pools but each involves about 1 square foot of treatment space for 1 square foot of pool. That means if you want an 850-square-foot-pool, you need 850 square feet of treatment space. It’s more expensive but it certainly looks cool!

GreenBuild Day 2: There’s something about GreenBuild

I’m mid-way through my second of three days at GreenBuild and something is different this year.

For the most part this conference just seems…. on. First, let me tell you that this is my third GreenBuild I went to GreenBuild 07 in Chicago, GreenBuild 08 in Boston and had guest posts on the blog at GreenBuild Phoenix last year. To read posts from each experience, click the ‘greenbuild’ tag below.

Personally, of the three, I think this is the best year yet. All the problems I had with my first Chicago GreenBuild experience:  insanely long lines for the keynote speaker, no clear way to compost food or recycle name tags, a tiny nonfunctional press room, teaching sessions focused on the lowest common denominator, almost rampant waste with giant programs and a general disorganization – are gone.

In its place three years later is a well organized, smoothly run conference. Sessions are easy to get into and focused on pertinent topics. People I’ve spoken with so far agree that this year, everyone seems to have a deeper level of green building knowledge. The press room is large with easily accessible outlets. Compost and recycling is clearly marked and encouraged. There’s also signs all around this exhibit hall stating that the carpet is going to be recycled or that giving out fliers is strictly prohibited without USGBC permission.  The USGBC also worked with food suppliers at the conference to make sure everything was organic.

There are also many more of my favorite kind of session: off site visits that demonstrate the unique aspects of the city you’re in.

There’s been changes in the exhibit hall. Rather than the standard conference practice of having every exhibitor give out literature that is often thrown directly in the garbage, the USGBC has instituted a program to curb that waste. More about this later.

That’s not to say that everything is perfect. But overall, I’m pretty impressed and looking forward to the rest of today and tomorrow.
