Need a building? You’ve got some new options

Posted on August 19, 2015

The following post is by Alaska Structures:

Much has been said about sustainable construction methods and how beneficial reclaimed and recycled materials can be to reduce the carbon footprint of a home or commercial construction project.  However, often overlooked are the many non-traditional building alternatives that provide an energy efficient shortcut to a complete building.

Shipping Containers

Highly durable and too often wasted, these hulking containers aren't just for subterranean bomb shelters anymore. DIYers and construction experts have been creating beautiful, functional, and livable buildings out of industrial shipping containers for several years now and we're thrilled with the results.

By reusing the massive metal containers for home construction, homeowners are able to enjoy sturdy walls, cool interiors, and endlessly expandable layouts. While working with standard shapes may feel limiting, many experienced container builders have found ways to create ventilated rooftops and innovative, expansive rooms using multiple container sections, as well as beautiful outdoor decks and living spaces.

While it takes a lot of hard work and logistical planning, the benefits of designing a custom home without the need for producing additional materials will provide a level of satisfaction beyond what typical sustainable building practices often provide.

Tensioned Fabric Buildings

Perhaps some of the most versatile structures available today, a high-end tensioned fabric building can sometimes outperform even a brick and mortar structure in terms of durability. These buildings can withstand significant snow load and high winds, will remain intact during natural disasters, and help lower insurance costs.

High-end fabrics can provide insulation and security in any climate on earth and some manufacturers go the extra mile with HVAC systems, electrical connections, and other custom options. The lightweight nature and ease of installation make these fabric buildings a great option for organizations on the move, but with so many foundation options, there's no reason why you can't install your fabric structure in place for good.

Worried about meeting building code? Depending on where you purchase your fabric building, the company's engineers may be able to meet or exceed various building code requirements mandated by your city or state governments.

Modular Buildings

Shedding the misnomer of "pre-fab" buildings, modular constructions aren't just for the temporary construction site, and are not like the double-wide trailers of 40 years ago. Entire hospitals, apartment complexes, and even hotels are being built using modular practices. By using modular methods, major projects have found success with reductions in construction time, site preparation, and shipping costs.

The production of modular buildings is more efficient, so they are a much more eco-friendly solution when compared with traditional construction. The construction industry accounts for about 40% of the energy consumption and greenhouse gas emissions in the United States. By using off-site manufacturing methods, the UK's Waste & Resources Action Programme suggests that construction site waste can be reduced by as much as 90%. Off-site construction also requires less heavy machinery use during the assembly process, further reducing emissions during the construction.

Modular buildings aren't just greener during construction either – many modular constructions come with super efficient HVAC systems, zero volatile organic compounds (VOCs), and glass walls/open office layouts that utilize more natural light.

Alaska Structures has manufactured fabric buildings for industrial and commercial applications around the world since 1975.

Seattle Lowrise Zones Now Have a Passive House Incentive to Add Floor Area

Posted on August 4, 2015

The following post is by Joe Giampietro, AIA, CPHC, NK Architects

11th and Republican PH Multifamily Rendering

On July 6th, the Seattle City Council passed a number of revisions to the low-rise zone land use code, including adding Passive House as a way to achieve floor area ratio (FAR) bonuses.

A FAR bonus allows for an increase in building height relative to the area of the lot. Passive House efficiency principles lead to significant energy savings, increased project value, and improved health and comfort for those that live there.

Although this was a minor addition to an otherwise hotly debated set of low-rise zoning updates, this addresses building energy use in a practical and cost effective manner. It is a big move in the right direction.

With the addition of Passive House to the other “green” incentive programs, including LEED Silver, Built Green 4-Star, and the Washington Evergreen Sustainable Development Standards for affordable housing, Seattle has started down the road of recognizing and providing incentives for truly high-performance, low energy design strategies.

Next on the list of legislative actions, the Passive House community is working with the Seattle City Council to consider expanding the Passive House incentive to include both current certification agencies, PHIUS and the Passive House Institute. We have successfully lobbied City Councilman, Mike O’Brien’s staff to include this adjustment in the “omnibus” zoning legislation. The expansion language is currently wending its way through the Council approval process and will be voted on later this summer.

We anticipate that this action will serve as a model for other changes in zoning legislation in Seattle as well as in cities and towns in throughout the Northwest. Let’s take a moment to celebrate one small step in this process!

How to prepare for the LEED exam

Posted on July 22, 2015

The following post is by Jess Foster:

iStock_000063149081_DoubleCongratulations on your decision to pursue a LEED Credential. These are the most sought after credentials in the green building industry by employers. A new study by Burning Glass Technologies shows that demand for LEED Green Associates and LEED APs has grown 46% in the last 12 months, so you’ve picked a great time to join in on this growing marketing need.

Your next step is to prepare for the LEED Exam. Here are some basic things you should know before selecting an exam prep program or materials:

1. Decide which credential exam to pursue:
There are several credentials you can earn based on your profession and your goals in the green building industry. I recommend looking at the USGBC site (the creator of LEED) or resources prepared by their recognized Education Partners like GBRI. Make sure to download the candidate handbook to understand eligibility requirements, registration and scheduling details.

2. Decide whether to study by yourself or sign up for an exam prep course:
Studying on your own can be challenging given the amount of material covered on these exams. Or, you can sign up for a LEED prep course. A quick Google search will show plenty of paid exam prep providers. Make sure the provider you choose is approved by USGBC or are USGBC Education Partners.

3. Choose an exam prep provider and course style:
Depending on your availability and schedule, there are several ways to prepare. There are live online classes where you attend for a month or so; on-demand only access courses where you watch sessions at your own pace; and in-person classes where an instructor teaches at a physical location. Make a selection that is right for you and your situation.Since the new LEED v4 test was released recently, you should carefully make a selection when registering for an exam prep program. An ideal exam prep course will include:

  • Narrated study materials/tutorial with option to download audio files
  • A study guide that you can print
  • Flash cards
  • Section or category quizzes (look for quizzes with answer explanations)
  • Simulated Mock Exams (at least two)

4. Study-study-study:
I recommend studying in a group or with a partner if you can. Finding someone to study with for your exam has many benefits. Some exam prep providers also provide group discounts, making it easier for your colleagues to join you in the pursuit of a credential. If you do chose to study independently with the support of a providers prep program, you’ll want to have a roadmap or plan to ensure you are staying on track and are covering all the material efficiently. Some USGBC Education Partners programs will include a recommended roadmap for you, taking even more of the guesswork out of studying.

5. Take MOCK exams:
Make sure you are completely prepared leading up to your LEED exam by using a trusted provider’s mock exams. This is your best gauge to ensure you will successfully pass the exam on your first try. This also gives you a targeted way to complete your studies and preparations based on the areas you find you are most lacking in during the mock exams. Once you successfully pass the mock exams you can feel confident going into the real thing.

Seattle fills a few tree pits with Flexi-pave

Posted on July 2, 2015
Demonstration of Flexi-pave installation

Demonstration of Flexi-pave installation

K.B. Industries installed a new material called Flexi-pave around several trees in Seattle to demonstrate its use for trees in business districts. The company has provided the material to the city free of charge to show how it works and train local contractors to install it. Flexi-pave can also be used for trails and sidewalk projects.

Flexi-pave has been installed at eight trees along Pine Street - between Second and Third avenues - and at five trees in McGraw Square.

Here are some of the advantages of using flexible porous material in tree pits:

• A safe, stable surface for pedestrians
• Allows air and water to pass into the soil to keep street trees healthy
• No weed or debris removal
• Cheaper than traditional tree grates

After a nine-year cleanup, Port of Everett site is a winner

Posted on June 4, 2015

ESY Before and NowThe Waterfront Place Central cleanup at the Port of Everett was named the Environmental Project of the Year by Washington Public Ports Association.

The site is a 65-acre former industrial property in the heart of the port’s 2,300-slip marina, which it says is the largest public marina on the West Coast. The site will become a new mixed-use development with public access, retail, commercial space and housing. Construction is expected to begin on that in 2016.

Between 2006 and 2015, the port has done cleanup projects across the 65-acre site, removing nearly 150,000 tons of contaminated soil, remediating groundwater plumes, dredging sediment from the bay, and removing failing bulkheads and other old creosote-treated wood structures.

Strider Construction did the upland cleanup, and Magnus Pacific did the in-water cleanup.

The port worked with Ecology to divide the 65 acres into six separate cleanup sites, with the ultimate goal of creating a new waterfront destination in Everett. The final, major cleanup at the site will be complete this month.

Port officials say Waterfront Place will unify the marina and surrounding property to create a unique community.

New earthwork blooms at 1250 Denny

Posted on May 26, 2015

Dillworth

“ALL RISE’s 2421 Miles,” is a new site-specific 52,000-square-foot earthwork by New York artist Molly Dilworth at 1250 Denny Way, the future site of Seattle City Light’s Denny Substation.

The Seattle Office of Arts & Culture says it uses over 400 cubic yards of dirt and 182 pounds of wildflower and grass seed to create a living “urban meadow.” There are 14 individual garden beds, each with a specific colorway.

The work is based on pattern studies from national flags, corporate logos and traditional patterns found along the sea trade route between Seattle and New York.

The city said Dilworth has traveled between New York and Seattle as a freelance worker for a global technology company. The work is named for that commute - the number of miles between the airports of Seattle and New York - made possible by modern global trade.

The Office of Arts & Culture said in a press release:

“As shipping and port technologies evolved over the last century, formerly industrial areas such as South Lake Union have been redeveloped. In a short time this lot on Denny will be a power station serving the demands of the new buildings; ALL RISE has used this temporary space to mark a transition between the last century and ours. The geometric edges of the garden will soften and evolve as it grows, just as our built environment and technologies do: imperceptibly, right in front of our eyes and seemingly all at once.

“The project was realized with the design assistance of Walker Macy (Portland and Seattle) as well as expertise and custom mixes from ProTime Lawn Seed, and the advice of SunMark Seeds.

ALL RISE is a series of temporary artworks at 1250 Denny Way. The goal is to provide a platform for artists to consider “the many iterations of land and space: residential, political, commercial, agricultural, spiritual, intellectual, utopian.” It is funded by Seattle City Light 1% for Art funds, and administered by the Seattle Office of Arts & Culture.

The project will stay through mid-June. You can view online webcams at www.allriseseattle.org.

Getting ready for new stormwater rules

Posted on March 30, 2015

Herrera is testing to see whether new soil mixes can remove
more heavy metals and other pollutants from stormwater.

Herrera is conducting groundbreaking research to assess and optimize the performance of LID systems.

Herrera is conducting groundbreaking research to assess and optimize the performance of LID systems.

With all the cranes towering overhead in downtown Seattle, it’s easy to forget the important work going on below to manage and protect our water as the region grows.

To keep pace with this growth, Washington State is pioneering the use of new and innovative approaches for stormwater management.  As of next year all development projects must use low impact development (LID) techniques or green stormwater infrastructure where feasible.  Rain gardens, bioswales, green roofs, and permeable pavement will become the norm rather than the exception.

As the region makes this new investment to protect our water, everyone - regulators, project owners, designers, and the general public included - will want to be confident these technologies are providing the intended benefit.

Herrera Environmental Consultants, Inc. is conducting groundbreaking research to assess and optimize the performance of these systems.

For example, with grant funding from the Washington State Department of Ecology, Herrera is currently implementing two research projects to develop a more effective soil media for use in bioretention systems.

In partnership with Kitsap County, one of these projects has involved numerous pilot scale tests of soil media components and blends to optimize their removal of heavy metals and other harmful pollutants from stormwater.

Herrera has also partnered with the City of Redmond to construct a state-of-the-art research facility for evaluating pollutant removal and plant growth in bioretention systems at full-scale.

Herrera Environmental Consultants, Inc. is an employee-owned engineering and scientific firm focused on restoration, water, and sustainable development.  Herrera is committed to working with our clients to develop innovative and sustainable solutions for infrastructure, natural resources, and stormwater projects.  Herrera was recently featured as “favorite green collar company” by the Seattle Times.

16 reasons you’ll want to live in a shipping container

Posted on March 9, 2015

A new website offers plans, advice and a community of container home fans.

I’m Tom Woods.  I run Container Home Plans along with my assistant Claire.  I have a background in construction and studied sustainable development at Yale. Whilst studying, I developed my passion for sustainable buildings and this is what caused me to come across the idea of making homes out of recycled shipping containers. Earlier last year, I was browsing online to try and find more information on how to build shipping container homes and was frustrated because I couldn’t find much information out there. This is how Container Home Plans was born.

So I made the site to act as a central online resource for shipping container homes and to help people who are looking for detailed information on how to build their own. We feature on our site case studies of other people who have built their own container homes and go in detail, outlining the materials they used, the length of time it took them and the cost of the build. We also run a feature called container home of the week, where we show off the very best shipping container homes as inspiration for people! It’s our hope that Container Home Plans will act as a hub for the community of container home enthusiasts so they can share their experiences with other enthusiasts and help each other as they build their own.

We run the site because we believe that using shipping containers can be not only environmentally friendly but it can also be a very affordable option that allows people to make homes they otherwise couldn’t afford to if they used conventional building materials.

I’d be delighted to hear from people, so feel free to send any questions to me at: tom@containerhomeplans.org.

Here’s a tool to help green roofs grow

Posted on February 9, 2015

The following post is by Oregon BEST:

A unique modeling tool developed at Portland State University with support from Oregon BEST is helping local green roof manufacturer Columbia Green Technologies speed adoption of green roofs to meet legislation aimed at reducing combined sewer overflows during heavy rains and thereby grow the Portland based start-up's national market share.

The new tool is the result of a research project funded by Oregon BEST and led by Graig Spolek, a PSU professor and director of the Green Roof Design and Test Lab. Columbia Green uses the tool when working with civil engineers and architects who need accurate, quantitative data about how much stormwater a green roof in a specific geographical location will both retain and detain.

A green roof sits atop the new Apple store in downtown Portland.

"This new tool has been very helpful; it's helped us open doors to some of the best engineering and architecture firms in the country," said Elaine Kearney, Technical Director at Columbia Green. "Being able to generate this kind of data bolsters our reputation as being innovative and technologically very forward looking."

Eric Zickler, an associate principal at Aecom, one of largest engineering firms in the world, said his firm uses many different tools to measure performance of their stormwater management infrastructure designs, but the Columbia Green tool stands out.

"Generally the calculators and modeling modules are generic and do not provide a high level of confidence in predicted performance," Zickler said. "The green roof stormwater management tool developed by Columbia Green is specific to green roofs and developed using both theory and empirical data for multiple geographies across varying storm intensities, making it a valuable resource in building our confidence in the stormwater management benefits of green roofs."

The new tool, which can generate data specific to geographic areas and weather patterns, gives Columbia Green a competitive advantage when the company interacts with potential clients.

"The ability to quantify our performance with this degree of accuracy is unique, so it's a significant advantage for us," said Robin Schneider, marketing director at Columbia Green.

This strategic funding exemplifies how Oregon BEST, a state-funded organization that fosters technology-based economic development, helps clean-technology companies collaborate with universities to advance and commercialize products to grow Oregon's green economy.

"It's been very rewarding to see Columbia Green leverage our investment in research and transform that into expanded distribution and sales opportunities," said David Kenney, president and executive director of Oregon BEST.

Green roofs and other green infrastructure approaches are gaining visibility at all levels of government, both in the United States and abroad, as officials try to implement policies to address aging public infrastructure.

Two years ago, Vanessa Keitges, CEO of Columbia Green, was selected to sit on the President's Export Council at the White House.

"We greatly appreciate the Oregon BEST support that allowed us to take advantage of the PSU rain lab and develop a tool that's helping us succeed," Keitges said. "Local cooperation between industries and academia is recognized as a model for innovation to solve global problems."

Oregon BEST is a state agency that nurtures clean technology innovation by transforming new ideas, research, and products into green-collar jobs, greater sustainability, and economic prosperity for Oregon.

See the Super Bowl in a whole new light: LED

Posted on January 21, 2015

The following post is by Ephesus Lighting:

It’s not the first time a championship football game will be played at University of Phoenix Stadium and the two teams will not be there for the first time. But for the first time ever, the big game will be illuminated by high performance LED stadium lights from Ephesus Lighting,  which provides LED lighting for sports facilities.

Earlier this season, University of Phoenix Stadium became the first NFL venue to light its playing surface with LED lighting. Ephesus reports the lights have been a hit with fans, players, broadcasters and facility operators.

“This year LED sports lighting proved to be ready for primetime as we illuminated more than 1,000 sporting events with our Ephesus LED stadium and arena lights,” said Mike Lorenz, President of Ephesus Lighting. “It’s fitting that the biggest sporting event in the world will be lit by our LED lights, the future of sports lighting.”

City of Glendale

The new LED fixtures at University of Phoenix Stadium slash energy use by 75 percent.

Ephesus fixtures, which are powered by Cree LEDs, provide an increase in illumination compared to the traditional metal halide lights that were previously installed at University of Phoenix Stadium. LED lighting also provides brighter and more uniform light which eliminates shadows on the playing surface, creating a better stage for players and fans, both in the stadium and watching on high-definition television.

The Ephesus installation is well-suited to HDTV broadcasting and feedback from broadcasters this season has been positive. Not only is the light brighter and more uniform across the playing surface, but the new lighting ensures that colors are reproduced more accurately. Since broadcasters do not need to open the camera’s aperture as wide to let in more light, they can present a clearer picture, show greater field depth, zoom in closer and even offer more detailed slow motion replays.

“The capabilities of LED technology have changed the way we view sports lighting,” said Joe Casper, Founder and CTO of Ephesus Lighting. “There is no doubt in our minds that both the fans in the stadium and millions more watching on television will see the game in a whole new light thanks to our ground-breaking system.”

University of Phoenix Stadium installed 312 Ephesus Stadium fixtures to replace the 780 metal halide fixtures. The new system uses just 310,000 watts of energy as compared to the 1.24 million watts needed to power the previous system for a 75% reduction in overall sports lighting energy consumption.

Additionally, LED lights can be turned on and off with the flick of a switch, whereas metal halide fixtures require a 20-minute warm-up period. This on/off feature allows facility operators to create light shows for fan entertainment, and, if a power outage were to cause a blackout, like it did in 2013 at the Superdome, the LED lights can be turned back on immediately with the flick of a switch.

“As the host venue for the 2015 Super Bowl, we are excited about demonstrating the benefits of LED technology to a global audience,” said Peter Sullivan, General Manager and Regional Vice President for Global Spectrum at University of Phoenix Stadium. “The Ephesus Lighting LED solution has improved lighting for the athletes, fans and broadcasters, all while reducing energy consumption and eliminating conventional sports lighting maintenance expense.”

The University of Phoenix Stadium has a retractable roof and field. The multi-purpose facility, which opened on August 1, 2006, previously hosted Super Bowl XLII in 2008, two BCS National Championship Games (2007 & 2011), the annual Fiesta Bowl, and numerous international soccer matches. The 63,400-seat stadium, which is expandable to seat 72,200 fans, is owned by the Arizona Sports and Tourism Authority (AZSTA) and operated by Global Spectrum.

Since lighting the first sports venue with LED technology in North America in 2012, Ephesus Lighting luminaires have been operational for over 300,000 hours in more than 100 indoor and outdoor sports and entertainment venues across North America.

Ephesus Lighting is a Syracuse, New York-based company that manufactures high-output LED lighting solutions for the industrial and sporting markets.
