The Danish architecture firm BIG with CG Jensen + EKJ + Grontmij said it has completed a new multipurpose hall for Bjarke Ingels’ former high school north of Copenhagen. The project turned a courtyard into a new gathering point above an underground sports facility.
The space can be used for sports, graduation ceremonies and social events.
BIG said in a press release the new hall is 16 feet below grade to ensure a good indoor climate and reduce its environmental impact. It is formed by beveled concrete walls and covered by a vaulted wooden roof made of curved glued laminated timber beams.
The roof functions as an interior and exterior skin, creating a hilly courtyard that can accommodate a number of activities from group work to larger gatherings.
The exterior surface is untreated oak and white enamel-coated steel benches that were designed by BIG. The only light sources at night come from the benches and seating, which are outfitted with LED lights underneath that brighten the entire courtyard.
The edge of the roof is a long bench with a lattice design that brings in daylight below. Solar panels around the buildings heat the hall.
Bjarke Ingels said, “Rather than placing the hall outside the school — and spread the social life further — we have created a new focal point and link between the school’s existing facilities. The roof forms a molehill that serves as a giant piece of informal furniture engaging and supporting student life.
“The main architectural idea emerged from the rules of handball as the soft, curved roof takes its form from the mathematical equation of the trajectory of a thrown ball. Form follows function. In an homage to my old math teacher, we used the mathematical formula for a ballistic arc to shape the geometry of the roof.”
A future phase will connect the courtyard and hall with sports fields and parking, and provide space for art classes and cultural activities.
BIG — Bjarke Ingels Group — describes itself as an international partnership of architects, designers, builders and thinkers operating within the fields of architecture, urbanism, research and development.

It's taken awhile to go from touring green homes to actually living in one, but for Becky Chan, it's been well worth it. Chan has been blogging her two-year journey, and says she got hooked on the idea as a result of visiting "homes built with recycled or reclaimed materials to reduce waste, homes with green roofs and living walls to slow stormwater runoff and filter pollutants, and the first net-zero-energy house built in Seattle.”
Now, those who plan to partake of this year's Green Home Tour on April 27, co-produced by the NW EcoBuilding Guild and Built Green of King and Snohomish County, will get to see her "deep green" remodel.
Parie Hines, LD Arch, designed the remodel and was impressed by Chan's focus on combining deep green ambitions with "thrift." Hines conservatively estimates a final construction cost of $150 per square foot (the original goal was $135 per square foot), pointing out that the new remodel includes high quality (and expensive) windows and infrastructure, while keeping finishes and details simple (and less expensive).
Chan's "Blue View, Green Built" net zero energy remodel is one of several in the North Seattle tour quadrant, and includes SIPS construction (3 walls were replaced with SIPS), rainwater harvesting, natural materials, salvaged/reused materials, solar PV, ductless mini-split heating, triple glazed windows, and a heat pump water heater. The home is also an example of deconstruction.
After the tour, she wanted to learn more, so she joined the NW EcoBuilding Guild, the nonprofit that has organized the free tour for three years. She also attended a net zero energy workshop conducted by Sustainable Ballard where she met Ted Clifton, TC Legend Homes. Clifton had built the net zero energy house Chan had so admired in the 2011 tour. She eventually hired him to conduct the remodel. She then bought a home, with remodeling in mind, that was conveniently located to services she knew she would need, proactively reducing her carbon footprint.
For those responsible for programming, funding, or otherwise involved with green building education, the hope is that this education translates to implementation. Chan's deep green remodel is a great example of how this works.
Kathleen O'Brien is a long time advocate for green building and sustainable development since before it was "cool." She lives in a green home, and drives a hybrid when she drives at all. She continues to provide consulting on special projects for O'Brien & Company, the firm she founded over 20 years ago, and provides leadership training and mentoring through her legacy project: The Emerge Leadership Project. Her book "Green Home Primer" is apparently on Becky Chan's bed stand (No kidding!)

The war over toxic chemicals and human health is spilling over into places we live and work: our buildings. The American Chemical Council (ACC) has launched an expensive and focused attack on the U.S. Green Building Council (USGBC) to protect the status quo of a small set of bad-actor manufacturers of toxic and obsolete chemicals. But innovative companies across the building industries and human health advocates are fighting back.
The American Chemical Council is lobbying to end the federal government’s use of the Leadership in Energy and Environmental Design (LEED) building certification system unless USGBC removes all references to human health. If successful, they will keep taxpayers from receiving the cost savings and productivity benefits that LEED certification has generated. Why does a chemical industry trade association think better buildings are such a threat, you ask?
The USGBC has transformed the global building industry with its emphasis on high performance, low energy and healthier building practices through its LEED certification program. In only a decade, LEED plaques have become synonymous with the best buildings in the world.
USGBC’s mission is to make buildings not only more energy-efficient, but healthier spaces for those who inhabit them. The new draft version of LEED seeks to assuage human health concerns of buildings by offering voluntary credits for buildings using healthy materials. Many in the health community see this as a long overdue step for the rating system.
The ACC, however, sees this as a dangerous threat to their member companies because a few of them make a pretty penny producing controversial chemicals.
So if you can’t beat ‘em, lobby against ‘em, right? ACC is doing what it does best -- spreading misinformation and shoving truckloads of cash into lobbying efforts to keep the market from abandoning toxic materials and embracing green chemistry.
They’ve even gone so far as to form the laughable “American High-Performance Buildings Coalition,” a group whose membership reads like a who’s who of industries that make unhealthy products, all uniting to lobby against LEED. From big chemicals to vinyl to adhesives to petrochemicals -- they’re all here.
These toxic trade associations are trying to convince us that they are the ones who truly support “green” building. Perhaps next they’ll suggest that their products only increase your odds of developing “green” cancer.
While they claim LEED is not consensus-based, this is demonstrably false. Any revision to the LEED standard must be approved through a democratic balloting process open to all 14,000 members of USGBC. These members are architects, engineers, builders, contractors and product manufacturers.
In fact, the ACC and many of its member companies are participating in the LEED development process. But when the professionals who purchase building materials began to suggest that a LEED credit be available for purchasing healthier building materials, suddenly the process is flawed, and not consensus-based.
In the real world, when your customers ask for something, you don’t lobby against their right to buy what they want, do you? Let’s hope these companies wake up and start to reign in their out-of-control trade association before people really start to notice who’s behind the curtain.
Green buildings are about more than energy and water conservation; they must also include consideration of human health. Hospitals have started to lead the way. The Health Product Declaration, an independent, open-source methodology for declaring content of building products, is ushering in a new age of transparency in corporate reporting. The Healthier Hospitals Initiative recently released targets for safer products that include credit for avoiding chemicals of concern in interior furniture. Major manufacturers of health-care building products have begun substituting PVC and phthalate plasticizers with safer alternatives. These firms are innovating and capturing market share.
While the ACC protests these LEED credits, we would venture to say their innovative members are investing in R&D to move to safer alternatives precisely because of these initiatives. The construction industry needs the USGBC and LEED; citizens do, too. Someone has to make the push to get these chemicals out of our faces.

People and businesses in Washington are now required to recycle fluorescent light bulbs and tubes. The new law covers residences as well as government, commercial, industrial, office and retail facilities.
Fluorescent tubes and compact fluorescent lights (CFLs) save energy but each light contains a small amount of mercury that can be harmful to humans and wildlife if it is not disposed of correctly. The mercury content in fluorescent tubes ranges from 3.5 milligrams to 8 milligrams or more for older lamps.
The most common types of lights that must be recycled include CFLs, fluorescent tubes and HID (high-intensity discharge) lights, such as mercury vapor, sodium vapor and metal halide lamps. It is now illegal to knowingly place mercury-containing lights in waste bins or landfills. All mercury-containing lights must be placed in a recycling container specifically designed to prevent the release of mercury. Mercury inside a light does not pose a concern while the light is in use and unbroken, but during disposal and waste handling, lamps are broken, releasing mercury vapor and potentially exposing waste handlers or others to mercury.
Mercury in the atmosphere is ultimately deposited back to the earth, rivers and lakes, where it can enter the food chain and accumulate in fish, which humans and other animals eat.
EcoLights was created in 1996 to recycle mercury-containing lights and both PCB and non-PCB ballasts. The company said it is a licensed “final destination” light recycler in Washington state.
Ecolights said almost every component of a fluorescent lamp can be recycled, including metal end caps, glass and the mercury phosphor powder. When lamps are recycled properly, they are crushed and the materials are separated under a continuous vacuum filtration process.
Glass, aluminum and phosphor powder are captured and recycled. Mercury phosphor powder is sent to a mercury retort for recovery of the mercury and rare earth metals in the powder.
EcoLights sells a pre-paid box for recycling. The company ships the box, protective inner bag, and instructions to users, who fill the box with lamps, and return it to EcoLights for recycling. EcoLights then e-mails a certificate of recycling to the user. The company said currently there are no fines or other legal consequences associated with non-compliance.
“EcoLights is committed to being a resource for helping businesses throughout the region understand and comply with the new law,” says Craig Lorch, EcoLights founder. “We want to make sure everyone is prepared for the transition.”

Silicon Energy, a manufacturer of solar photovoltaic modules in Marysville, said it is releasing the Next Generation Cascade Series PV module.
The first generation came out in 2007.
The new module uses less embedded material, which improves performance and output.
Here are some features of the new module:
· Anti-reflective coating on the front glass
· Advanced encapsulant
· Lighter weight mounting hardware
· About 30% fewer roof penetrations to reduce costs and speed up installation
· 12 AWG wire for reduced voltage drop
· Amphenol connectors with a higher current rating and increased reliability
· American Fittings Raintight conduit connectors that improve mechanical and electrical bonding
Gary Shaver, president of Silicon Energy said, “Our relationships with suppliers and research laboratories allows our engineering team to integrate innovative concepts and advanced material sciences into our products. We’re excited to see how architects and building designers integrate our new, even more attractive Cascade Series PV modules into the building envelope and overhead structures to achieve contemporary and functional designs.”
The module has a double-glass, open-frame design to shed water, dirt and snow. Airflow behind the module keeps the system cooler, which boosts performance. Custom mounting hardware colors are available.
Silicon Energy is shipping the Next Generation module to Washington customers and will introduce it in other markets early next year.
Silicon Energy was founded in 2007, and is located in Washington and Minnesota.

The last few months have been busy at the Bullitt Center construction site on Madison Street, with structural, glazing, mechanical and other systems taking shape.
The Type-4 heavy timber structure is a first for Seattle since the 1920's, when heavy timbers were used in most commercial buildings. In the interim, the technology of heavy timber structures has advanced, with glued-laminated timbers replacing solid wood in many cases. Of course, forestry practices have also improved in the last 90 years, with 100% of the wood used at the Bullitt Center coming from Forest Stewardship Council certified forests.
At this point, the structural work at the Bullitt Center – designed for a 250-year lifespan – is largely complete, with the roof firmly in place.
With the structure complete, work turned to the curtain wall. Of particular note, the Schuco window system being used is arguably the most efficient in the world. Yet before the Bullitt Center, these windows were not easily available on the West Coast, since the manufacturer was in Germany – quite a distance to ship windows weighing hundreds of pounds each. To address this challenge, the team was able to connect Schuco with Goldfinch Brothers, a glazing company in Everett, WA. Now Goldfinch is the exclusive manufacturer of the Schuco window system on the West coast, providing windows for the Bullitt Center and other projects.
On the mechanical side, the rainwater collection and treatment system is being built throughout the project, from roof to basement. While approval to use rainwater for drinking is pending, it is our hope that the Bullitt Center can help demonstrate that ultra-filtration, UV and activated charcoal can treat water as well as – if not better than – chlorine (which can't be use in the project, because chemicals are not allowed for water purification by the Living Building Challenge).
At this point, the Bullitt Center is on track for completion later this year, with occupancy by commercial tenants starting in January 2013. Conversations with potential tenants are underway, and interested companies should contact Point32, the project development partner, for more information.

The roof of the Bullitt Center on East Madison Street is under construction now and all the structural elements are in place.
Today President Rosen Plevneliev from Bulgaria, who is a former real estate developer, will tour the Bullitt Center as part of a trade mission to Seattle.
After campaigning for president on a platform that included energy efficiency in buildings, Plevneliev will be in Seattle today before heading to the NATO summit in Chicago next week. His visit to Seattle is focused on international trade and economic development. In particular, he is interested in learning about green building and clean energy technology, which is why he is touring Bullitt Center, the world’s greenest office building.
In the next few weeks, we will begin outreach to brokers to begin marketing office space inside the Bullitt Center. It will be marketed at rates comparable to new class-A space in downtown.
The HVAC system is going into the building, including the six-story composting toilet system.
McGivra Place, the park next door, now has a final design direction and the process is moving forward, with re-development expected later this summer or early fall. The park project is the first to pursue the Living Building Challenge for landscapes.
