How green is the future? Yudelson’s 2014 predictions

Posted on January 14, 2014

The following post is by DJC staff:

Sustainability consultant Jerry Yudelson, has released his annual list of the top 10 green building trends and says he expects this year will see a rapid increase in energy retrofits on existing buildings, a new focus on water conservation, and a switch to cloud-based systems for monitoring and managing energy use.

Jerry Yudelson

He says the expansion will be global thanks to the economic recovery in most of Europe and North America. “There is no doubt that we are seeing more agencies, architectural firms, development organizations and companies building green each year,” he writes, “and there is nothing on the horizon that will stop this MegaTrend or its constituent elements.”

By the way, Yudelson also announced he is the new president of Green Building Initiative, the organization responsible for the Green Globes green building rating and certification system that he says is increasingly competing with LEED.

Yudelson Associates’ Top 10 Green Building MegaTrends for 2014

  1. Green building in North America continue its strong growth in 2014, with the ongoing expansion of commercial real estate construction together with government, university, nonprofit and school construction. This will build on the fact that in 2013 green building project registrations in new construction accounted for about 30% of all new projects.
  2. In 2014, there will be rapid uptake of energy-efficiency green building retrofits.. Note: this trend will be strongest in corporate and commercial real estate, along with the “MUSH” market (Municipal, University, School and Hospital) projects, given the availability of cheap financing and the rise of numerous new players in the building energy retrofit market. Yudelson says absolute building performance, and resultant operating cost, (vs. the relative improvement approach still enshrined in most rating systems) is going to be an increasing focus for building owners.
  3. Zero-net-energy buildings are become increasingly commonplace, in both residential and commercial sectors. LEED and ENERGY STAR certifications and labels have become too commonplace to confer competitive advantage among building owners. Developers of speculative commercial buildings have also begun to showcase Zero Net Energy designs in order to gain marketplace advantages. Systems such as the Net-Zero Certification of the International Living Building Institute are driving this trend, but it has been growing steadily for about five years.
  4. LEED will see enhanced competition from Green Globes. This trend is supported by the fact that the Federal government has released its “once every five years” assessment of rating systems and has now put the two systems on an equal footing for government projects. More importantly, LEED will struggle to convince owners, designers and consultants in all sectors that LEED v4 represents more value than hassle.
  5. The focus of the green building industry will continue its switch from certifying new building design and construction to full greening of existing buildings. This trend has been in place since 2010, and we expect it to accelerate in 2014.
  6. Green Buildings will increasingly be managed by information technologies, especially those in the “Cloud.” This trend is reflected by the large number of new entrants and new products in fields of building automation, facility management, wireless controls and building services information management over the last three years. In fact, we are calling 2014, “The Year of the Cloud” for how quickly this trend will become fully established.
  7. Green Building Performance Disclosure will continue as a major trend. This is highlighted by disclosure requirements enacted in 2013 by more than 30 major cities around the country, laws that require commercial building owners to disclose actual green building performance to all new tenants and buyers and, in some places, to the public. This trend will spread rapidly as the easiest way to monitor reductions in carbon emissions from commercial and governmental buildings.
  8. Healthy Building Products, Product Disclosure Declarations, along with various “Red Lists” of chemicals of concern to healthy building advocates, will become increasingly contentious. This trend has manifested through such tools as the Health Product Declaration and the inclusion of points for avoiding certain chemicals contained in LEEDv4, currently scheduled for full implementation in 2015. We predict that building product manufacturers will increasingly try to gain or maintain market share based on open disclosure of chemicals of concerns. We also foresee that industry-developed disclosure systems will begin to compete with systems offered by dozens of third-party rating agencies.
  9. Solar power use in buildings will continue to grow, especially because of the prospect of increasing focus on implementing aggressive state-level renewable power standards (RPS) for 2020 and the move toward zero-net-energy buildings. As before, third-party financing partnerships will continue to grow and provide capital for larger rooftop systems on low-rise commercial buildings, parking garages, warehouses and retail stores, as well as on homes.
  10. Awareness of the coming crisis in fresh water supply, both globally and in the U.S., will increase as global climate change affects rainfall and water supply systems worldwide. Leading building designers, owners and managers will be moved to take further steps to reduce water consumption in buildings by using more conserving fixtures, rainwater recovery systems and innovative new onsite water technologies.

Transparency: the new mantra

Posted on December 24, 2013

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."

BIG’s hilly courtyard tops a new gym

Posted on August 13, 2013

The following post is by DJC staff:

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.

Photo by Jens Lindhe

Architect Bjarke Ingels says he considers the roof a giant piece of informal furniture.

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.

House gets a deep green remodel for $150 a square foot

Posted on April 17, 2013

The following post is by Kathleen O'Brien:

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.”

Photo by Becky Chan

This year's Green Home Tour will include Becky Chan's net-zero energy house, which has a 6.72-kilowatt solar array.

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!)

When it comes to certified wood, GSA is right to question LEED

Posted on April 4, 2013

The following post is by William Street:

Contrary to what Meghan Douris wrote in these pages in your Building Green issue (“Is LEED’s Future with Federal Projects Under Threat?” 2/28), the Government Services Administration is correct to seek opinion regarding LEED’s acceptability for public procurement projects, given the cost involved with LEED certification and LEED’s unfortunate discrimination against two respected and widely used certification standards, the Sustainable Forestry Initiative (SFI) and the American Tree Farm System (ATFS).

Photo by Luciano Burtini/sxc.hu

There's more than one forest certification system.

The fact that GSA is seeking input on their use of green building rating systems is a positive development. This will hopefully shed light on the problem with GSA’s use of the US Green Building Council’s LEED rating system. USGBC, unlike Green Building Councils in Italy, Germany or Australia -- all of which recognize the importance of all forest certification systems -- has been victimized by narrow interest groups seeking to push their own political agenda at the expense of actual science-based energy efficiency, local jobs, competitiveness and inclusivity. USGBC has never publicly explained why they only reward wood certified to the Forest Stewardship Council standard.

PEFC, the world’s largest and only purely non-profit forest certification system -- which includes SFI and ATFS,  both of which are independent, non-profit, charitable organizations -- has proven on every continent and in all governmental procurement and independent and neutral evaluations that it is a superior system to FSC. PEFC affiliates are recognized by Green Building Councils in many other countries, but not by the USGBC. Thus, wood products from SFI and ATFS are placed at a market disadvantage while forest products from FSC (many of which are sourced outside of the U.S.) are accepted, even though FSC‘s for-profit structure is not recognized by, and fails to comply with, the International Accreditation Forum (IAF) and ISO guidelines.

In the U.S., SFI and ATFS are the only forest certification systems to require and enforce compliance with the International Labor Organization’s core labor standards for forest workers.  Strong labor standards mean safer work, better wages, sustainable jobs and viable rural communities that depend on them.

Rather than attempt to create a monopoly for FSC, USGBC should do what practically every other national and third-party system has done: recognize and reward wood from all sustainably managed forests. To do otherwise is to promote deforestation in the tropics and the conversion of sustainably managed forests here into resorts, golf courses and second homes.

It’s well past time to stop fighting over the well-managed forests of North America and start speaking with a single voice to send a unified message to the rest of the world: that green buildings benefit from using wood from all sustainably managed forests. By speaking with a single voice, Americans can truly be a force against deforestation and the conversion of forests to other land uses.

Chemical trade group lobbies to block LEED

Posted on February 19, 2013

The following post is by Robin Guenther:

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.

Guenther

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.

SXC.hu file photo

A high-performance building?

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.

Light recycler helps businesses dispose of fluorescent lights

Posted on January 7, 2013

The following post is by DJC staff:

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.

You can't throw these away now.

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.”

Information about the new law is available on the state Legislature website or at EcoLights.com.

Scrap metal demolition is green, but not always easy

Posted on December 20, 2012

The following post is from Elder Demolition:

About 40 percent of the solid waste produced in the U.S. comes from construction and demolition debris. In 1996, the U.S. Environmental Protection Agency reported that the debris generated from construction and demolition projects totaled 136 million tons. Since then, this figure has increased by 25 percent. Building demolitions are responsible for about 48 percent of this waste, while renovations contribute about 44 percent. Since steel is one of the most popular materials used in construction, green scrap metal demolition is getting a second look.

Scrap metal recycling can reduce disposal fees and demand for raw materials.

Builders are diverting metals harvested during demolitions from landfills for reuse in new projects. Instead of tearing down a building as fast as possible, builders deconstruct them in order to salvage parts they can reuse, recycle or sell. Scrap metal recycling isn’t a new concept in the metal industry. Here’s why:

It reduces demand. Steel and other metals have valuable minerals in them, such as nickel and chromium. By choosing to recycle scrap metal waste, you can help reduce the demand for raw materials and the energy required to refine them.

It saves money. Often you can reuse the metal salvaged during a green demolition, thus reducing disposal fees. If there’s metal that you can’t repurpose, there’s the option of selling it or making a tax-deductible contribution to a non-profit building supply company.

You can earn green points. A green demolition may qualify your project for LEED points or a related certification. Builders can also earn points by planning new construction with a future green deconstruction in mind.

Salvaging scrap metal is a time- and work-intensive process. When dismantling an aluminum plant, for example, our company harvested 35,000 tons of structural steel. This involved using steel shears to cut the larger scraps into smaller pieces for transporting. Then the smaller pieces must be gathered and separated from the rest of the construction debris — in many cases, this requires a crew to comb through the site and separate the materials by hand, which is dangerous as well as time-consuming. We’ve found the use of magnets to be the safest and most efficient way to extract scrap metal from a site.

One rookie error demolition companies commonly make is not properly sorting the different types of metal. It’s usually fairly obvious that any copper, aluminum or other precious metals should be separated. However, once these materials have been removed, many crews will simply gather the remaining metals into one load. That means heavy structural steel often gets mixed together with ductwork, metal wall studs, light fixtures and other less valuable metals. At the scrap yard, just a few pieces of these undesirable materials can diminish the value of the heavy steel as much as 20 percent — that’s $25-50 per ton. When you’re hauling 10-12 tons of scrap metal for resale, this can be a costly mistake.

For more information about scrap metal demolition, and site management, stormwater management and eco-friendly opportunities in the area, the Pacific Northwest Pollution Prevention Resource Center and the EPA provide a list of green building resources and certification programs available in Oregon and Washington.

Portland-based Elder Demolition has experience with scrap metal demolition, scrap metal recycling and LEED-certified green demolitions.

New module from Marysville solar manufacturer

Posted on November 30, 2012

The following post is by Silicon Energy:

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.

Silicon Energy's new photovoltaic panels.

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.

This is not your grandfather’s heavy timber structure

Posted on August 17, 2012

The following post is by Brad Kahn:

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.

Photo by John Stamets

Glaziers install windows on the sixth floor.

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.

A rainwater collection and treatment system is being built throughout the project.

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.

Brad Kahn is president of Groundwork Strategies. He manages communications for the Bullitt Center project.
