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.

What’s missing in green buildings? Training

Posted on December 2, 2014

The following post is from Washington State University:

More than one-third of new commercial building space includes energy-saving features, but without training or an operator’s manual many occupants are in the dark about how to use them.

Julia Day recently published a paper in Building and Environment that for the first time shows that occupants who had effective training in using the features of their high-performance buildings were more satisfied with their work environments. Day did the work as a doctoral student at Washington State University; she is now an assistant professor at Kansas State University.

Julia Day

She was a WSU graduate student in interior design when she walked into an office supposedly designed for energy efficiency and noticed that the blinds were all closed and numerous lights were turned on. The building had been designed to use daylighting strategies to save energy from electric lighting.

After inquiring, Day learned that cabinetry and systems furniture throughout the building blocked nearly half of the occupants from access to the blind controls. Only a few determined folks would climb on or under their desks to operate the blinds.

“People couldn’t turn off their lights, and that was the whole point of implementing daylighting in the first place,” she said. “The whole experience started me on my path.”

Working with David Gunderson, professor in the WSU School of Design and Construction, Day looked at more than 50 high-performance buildings across the U.S. She gathered data, including their architectural and engineering plans, and did interviews and surveys of building occupants.

She examined how people were being trained in the buildings and whether their training was effective. Sometimes, she learned, the features were simply mentioned in a meeting or a quick email was sent to everyone, and people did not truly understand how their actions could affect the building’s overall energy use.

Green-building occupants aren't always taught how to use the building's energy-saving features.

One LEED gold building had lights throughout to indicate the best times of day to open and close windows to take advantage of natural ventilation. A green light indicated it was time to open windows.

“I asked 15 people if they knew what the light meant, and they all thought it was part of the fire alarm system,” she said. “There’s a gap, and people do not really understand these buildings.”

According to CBRE Research, the amount of commercial space that is certified as high-performance in energy efficiency through the U.S. Environmental Protection Agency’s Energy Star or U.S. Green Building Council’s LEED has grown from 5.6 percent of commercial space in 2005 to 39.3 percent at the end of 2013.

Yet in many cases, the corporate culture of energy use in buildings hasn’t caught up. While at home our mothers nagged us to turn off the lights when we left a room or to shut the door because “you don’t live in a barn,” office culture has often ignored and even discouraged common-sense energy saving.

Day found that making the best use of a highly efficient building means carefully creating a culture focused on conservation. In buildings with an energy-focused culture, workers were engaged, participated and were satisfied with their building environment.

“If they received good training, they were more satisfied and happier with their work environment,” she said.

She is working to develop an energy lab and would like to develop occupant training programs to take advantage of high-performance buildings.

“With stricter energy codes, the expectations are that buildings will be more energy efficient and sustainable,” she said. “But we have to get out of the mindset where we are not actively engaged in our environments. That shift takes a lot of education, and there is a huge gap right now.”

Frank Ching illustrates new green building guide

Posted on June 6, 2014

Architect Francis D.K. “Frank” Ching, a professor emeritus at the University of Washington, is co-author of Green Building Illustrated, a newly published guide to green building design and construction.

Ian Shapiro, co-owner of Taitem Engineering in Ithaca, N.Y., wrote the text, and Ching was the illustrator.

The book, written for architects, engineers and builders, offers a variety of in-depth approaches to green building design, including a visual presentation of the theory, practices and complexities of sustainable design.

Shapiro emailed the DJC this description from Wiley, the publisher:

From the outside to the inside of a building, (the authors) cover all aspects of sustainability, providing a framework and detailed strategies to design buildings that are substantively green. The book begins with an explanation of why we need to build green, the theories behind it and current rating systems before moving on to a comprehensive discussion of vital topics. These topics include site selection, passive design using building shape, water conservation, ventilation and air quality, heating and cooling, minimum-impact materials, and much more.

Ching recently retired after more than 35 years of teaching. He is the bestselling author of Building Construction Illustrated, among other books on architecture and design, all published by Wiley. His works have been translated into more than 16 languages and are regarded as classics for their renowned graphic presentations.

Shapiro has been a visiting lecturer at Cornell University, Tompkins-Cortland Community College and Syracuse University. He has worked on several LEED building design projects, has led a variety of energy conservation research projects, and is a frequent contributor to ASHRAE Journal and Home Energy magazine.

The guide is available at local bookstores, including Ada’s, Elliott Bay and the University Book Store.

Deconstructing sustainability

Posted on November 13, 2013

The following post is by Kathleen O'Brien:

There's some discussion among professionals and sustainable building advocates about market "fatigue" as regards green building.  Given the tendency of many in the industry to value and use green building techniques for their marketing benefits above all else, this is no surprise.

Author Lance Hosey warns that if sustainability is treated as a style, then it can go out of style.

In his recent book, The Shape of Green, Lance Hosey notes that "associating sustainability with its trappings rather than its principles risks looking passé."  When sustainability is treated as a "style," says Hosey, "it can go out of style."  He describes the unfortunate and conspicuous use of green technologies such as solar panels or a green roof on buildings that are pronounced sustainable, but have little to say for themselves other than the "green bling" they are sporting.

But Hosey does far more than bemoan this circumstance, and he doesn't suggest tossing out the concept of sustainability because some marketers are onto the next new thing, or some architects continue to view (wrongly) that sustainability is inelegant and antithetical to high design.  In my view, Hosey returns sustainability to its rightful place when he reminds us that sustainability  is a set of "principles and mechanics for making design more responsive and responsible, environmentally, socially, and economically."   Designers need "an aesthetics of ecology" that can "guide designers to make things more environmentally intelligent, humane, and elegant all at once."

Hosey is asking us to shift our perspective from technological design to ecological design, and offers three principles that together result in sustainable solutions:  conservation, attraction, and connection.  Well worth the read.

Kathleen O'Brien is a long time advocate for and prolific writer about 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. Recently retired from O'Brien & Company, the green consulting firm she founded over 22 years ago,  she is now the Executive Director of The EMERGE Leadership Project, a 501c3 nonprofit whose mission is to accelerate life-sustaining solutions in the built environment through emergent leadership training.

Old warehouse becomes cool new school

Posted on September 13, 2013

The following post is by Dennis Erwood:

Once a year, a single school within the entire state of Washington is recognized by The Council of Educational Facility Planners International (CEFPI) for its exemplary design approach. This year, the coveted “Polished Apple” was awarded to the Northshore School District for its newly opened Secondary Academy of Success (SAS). The school is no stranger to such recognitions. Since it opened in 2010, it has won accolade after accolade, which raises the question: What does it take to design an award-winning school?

Secondary Academy for Success

Adaptive re-use: With space as a major constraint for new schools, the school district looked outside the box for unconventional solutions, turning to a former warehouse for the site of the new school. The business park location also made sense for SAS, as the school partners with businesses to provide students with real-world opportunities and experience.

Adaptive design: The team also looked for creative ways to use existing infrastructure to avoid major modifications that would increase costs. The raised loading dock created a second entrance for middle school students.  Support columns and trusses were carefully blended as elements of the interior design. Windows, lighting, color and materials were reconsidered to create a space that would be inviting.

How it looked before the renovation

Sustainable solutions: With a commitment to reducing its carbon footprint, the school district also looked for ways to incorporate sustainable design. Wind-powered generators, solar panels, operable windows and high-performance glazing were integrated as cost saving and green solutions. Real-time energy and water usage is shared with students and teachers via “green dashboards,” providing data for use in curricula that paves the way for potential green jobs. Perhaps the “greenest” element of all is the re-use of a former space instead of using the natural resources required to create an entirely new one.

The resulting design approach successfully transformed a one-story, monochromatic, car-focused warehouse into a natural light-filled, two-story learning environment with an outdoor plaza, classrooms, dining and common spaces that invite learning and collaboration.

Dennis Erwood, AIA, leads the education studio at the Seattle-based architectural firm Studio Meng Strazzara. He can be reached at DErwood@studioms.com.

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.

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!)

A rooftop P-patch grows in Columbia City

Posted on September 21, 2012

The following post is by DJC staff:

Harbor Urban says people are starting to move into the GreenHouse Apartments at 3701 S. Hudson St. in Columbia City. The LEED gold project has one notable feature: irrigated garden plots for each resident on the roof.

Harbor calls it “roof-to-fork urban agriculture.”

There’s also a greenhouse on the roof and a communal space for dining, as well as edible trees and shrubs scattered throughout the property. The rooftop plants absorb rainwater and reduce runoff, and the soil and vegetation help insulate the buildings.

Rooftop gardens and greenhouse at Columbia City's GreenHouse Apartments.

The site is near the Columbia City light rail station and the farmers’ market.

Harbor said half of the units were leased before the building officially opened.

Harbor Urban, LLC is the developer, Exxel Pacific built it and Runberg Architecture Group was the architect. The landscape architect was Hewitt and the structural engineer was CPL. LEED consultant was O’Brien & Co.

Martha Barkman, director of design and construction for Harbor Urban, said, “We spent a lot of time early in the entitlement stages to make sure it was something that would be accepted by and truly fit into the existing community, which is a unique treasure.”

Harbor said GreenHouse is the first new market-rate apartments in Columbia City since 1969.

GreenHouse has 124 units, 20 percent of which are designated affordable under Seattle’s Multi-family Tax Exemption program.

This post has been updated since it was first published to name additional project team members.
