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.
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.
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.

Housing affordability and the impact of the Puget Sound region’s dwindling supply of buildable land was the focus of the recent Master Builders Association of King and Snohomish Counties' (MBA) 2014 Housing Summit in Bellevue.
“Accommodating Housing Needs with Less Land” included presentations by top national and regional housing experts and a panel discussion with state legislators and homebuilders.
“There is an explicit link between the availability of buildable lands and housing affordability,” said MBA Executive Director Shannon Affholter. “The Summit served as a starting point in a frank discussion about what’s working, and what’s not, in meeting the Growth Management Act housing targets and the region’s growing needs.”
A presentation by Todd Britsch, regional director for Metrostudy Inc., a leading provider of research and analysis to the housing industry, underscored the immediate challenge to the buildable land supply: based on projected population growth, King County has 3.87 years of supply remaining of assumed total inventory, and only 3.29 years of supply in Snohomish County.
“We’re seeing lot prices absolutely skyrocket, and the numbers are staggering. It’s a long-term issue and we have to address it sooner rather than later,” he said. “And if we don’t, the Puget Sound region is going to become the next San Francisco Bay Area, where only the ‘elite of the elite’ can afford to own a home.”
Nancy Bainbridge Rogers, land use attorney at Cairncross & Hempelmann, noted that GMA-mandated Buildable Lands Reports generated periodically by counties don’t provide a full and accurate picture of future trends.
“The reports compare housing targets to the actual growth. The reports must determine whether sufficient land exists to accommodate population projections. Unfortunately, the reports are not required to include a feasibility component or an assessment of affordability.”
A lively panel discussion focusing on legislative solutions included Senator Joe Fain (R) 47th District, from Auburn; Senator Marko Liias (D) 21st District, from Mukilteo; Representative Jay Rodne (R), 5th District, from Snoqualmie; and Representative Larry Springer (D), 45th District, from Kirkland. Other participants included homebuilders Mark Kaushagen of the Pulte Group and Lynn Eshleman from Pacific Ridge Homes.
Individual panel members cited specific action items that could advance the goals of housing availability and affordability, including:
- couple housing demand with affordability in future planning
- passage of a transportation package and infrastructure financing bill
- comprehensive review of the Urban Growth Boundary and its possible expansion
- require cities in King and Snohomish counties to do a planned action on remaining undeveloped lands to assess infill housing opportunities
- eliminate redundancies in the review and permitting process, and establish a meaningful time limit in which permits can be outstanding.

There’s been a lot of controversy over the expense and effectiveness of LEED certification. The controversy is affecting the perception of LEED, driving governments to remove laws requiring certification for publicly funded projects and pushing organizations that used to pursue Gold at a minimum to pursue Silver as a maximum. It’s a disturbing trend that is ill-informed.
Many projects achieve LEED certification without any impact to their construction budget. Of course there are registration and certification fees that cannot be avoided but those costs are generally inconsequential. The costs to achieve LEED that do get noticed are the ones that change the design. Often times the contractor is not expected to change the outcome of LEED certification as many of the decisions and features were included during design. However, the contractor can contribute significantly by taking an active and educated role in the LEED process.
Design Document are not Absolute: Work with and educate your entire team and you’ll be surprised at what you can accomplish.
On a project we recently completed for Celgene we were able to achieve 30% Recycled Content, well beyond the initial 10% that was indicated on the LEED Scorecard. By identifying all scopes of work that could contribute Recycled Content and working directly with our subcontractors to help them understand what we were looking for and the documentation we needed to support it we were able to substantially increase the recycled content and contribute an additional 2 points to the project. Collaboration and education were key to accomplishing this.
Know the Intent of a LEED Credit and Get Creative: Many LEED Credits are achieved using one of few technologies or methodologies but sometimes simple, creative solutions can be used with little added cost.
At Northeastern University’s Seattle Campus we initially dismissed achieving LEED CI EA Credit 1 for HVAC Zoning because two private offices shared a single VAV box and the cost was determined to be prohibitive to add an additional one. The fact that we were so close to meeting the criteria kept nagging at the team. One day someone asked why we couldn’t control a damper using the occupancy sensors already installed for the lighting. It turns out that we could! While, not a typical way to achieve the credit the USGBC agreed that this simplified occupied/unoccupied status of providing ventilation to the space sufficiently met the zoning criteria.
Understand the Goals, Build it Effectively: If you understand the end goal, not the specific technology, you can find better solutions at a lower cost without affecting the project.
Plymouth Housing’s LEED Platinum Williams Apartments included a solar thermal system in the design. Initially, the project assumed that evacuated tube collectors would be used on the project, indeed the attractiveness of this newer technology and the capacity to produce higher temperature water appears to be the best option. However, looking at total cost combined with efficiency led us to a different conclusion. In our research, on a flat roof where the angle we could set the collectors was infinite the efficiency of the two systems were nearly identical and the costs roughly the same for the same heating capacity. However, the evacuated tube collectors needed twice the roof area, twice the racking, more connection points in the roof and longer piping. The flat plate collectors were the lowest first and life-cycle cost. The savings between these two systems allowed us to include upgrades elsewhere that further enhanced the sustainability of the project.
As you can see, these examples did not involve spending large amounts of money but raised the certification level for each project. There are more than enough examples of LEED by addition and these are the projects that give opponents of LEED something to argue. These projects prove that LEED can be a tool of inspiration, when used as such pushes everyone on a team to do more with the same, or less, resources.

Rand Lymangrover thought he had tried everything. His company, Totem Ocean Trailer Express (TOTE), was failing to meet benchmarks for their general stormwater permit for the runoff from their Port of Tacoma facility. The main problems were zinc and copper: two metals in abundant supply at an industrial terminal with lots of galvanized fencing and heavy vehicle traffic.
After failing to get below benchmarks by cleaning up and installing stormwater vault filters, Lymangrover turned to rain gardens. If it worked, he reasoned, the company would save money: at $24,000, it would cost about 10 percent of a more traditional, industrial-scale filtering system.
The contractor was David Hymel with Rain Dog Designs. The rain gardens were installed with the help of Stewardship Partners, which is working with Washington StateUniversity to install 12,000 rain gardens in the Puget Sound region.
Three years later, the rain gardens are working perfectly and are a regularly visited by other industrial businesses, city council members and many others.
“In addition to getting us below the benchmark, the rain gardens have really improved how things look down here and show that this green infrastructure feature works at an industrial level,” Lymangrover said. “You can always find a place to do a rain garden.”
During heavy rainfall, the TOTE rain gardens can handle over 160 gallons of runoff per minute.
Lymangrover invites other industrial businesses that are looking for solutions to their stormwater issues to consider a rain garden – and visit the ones at TOTE. His ultimate goal: to eliminate all stormwater runoff from the terminal.

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.
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 stairwell is lined with fir wood salvaged from a pair of 1920s-era buildings that once stood on the site. The buildings were last owned by Fremont Dock Co., which acquired them in the 1980s.
Salvaged wood gives the staircase a look and feel that’s unusual for new construction, Skanska says.
The 129,000-square-foot project will house the Brooks Sports headquarters when it opens this summer.
Curious about the salvaged wood? Skanska passed along these tidbits:
• 45 pieces of lumber were salvaged before the old buildings were demolished. All the wood in salvageable condition was reused.
• Milling work requires a great deal of raw material, so the Skanska team turned to one of its other developments, 400 Fairview in South Lake Union, to supplement the supply with another 140 linear feet of wood.
•Using wood from the 400 Fairview site — also fir — was not easy since it had to match Stone34’s milling profile and be in good condition.
• The salvaged wood will also be used for slats beneath several glass canopies. On the north side of the building savaged wood is used as exterior cladding.
• 98 percent of the construction waste has been diverted from landfills.
• Non-salvaged wood at Stone34 is FSC-certified, meaning it was harvested from responsibly managed forests. Examples include Stone34’s outdoor benches and the lobby floor.
The following post is by DJC staff:
Windfall Lumber was started in 1997 in Tumwater with one goal: to sell wood responsibly.
It uses reclaimed, salvaged and FSC-certified wood to make tables, countertops, architectural wall cladding, panel and flooring products.
Every piece handcrafted by Windfall Lumber has a story. Wood comes from telephone poles, gym floors, shipping pallets, hardwood scraps, trees downed by windstorms, deconstructed granary storage bins and warehouses, as well as FSC hardwoods grown in the Pacific NW.
Interior designers, architects, builders and homeowners have used Windfall Lumber products, and they can be found locally at Starbucks, Whole Foods, Amazon, Olympia Coffee Roasting Co., University of Washington, Washington State University, Seabrook and Clover Park Technical College.
Tables and countertops come with live-edge, end grain and butcher-block designs. Wall cladding comes in stained and textured finishes. New colored cladding is now available. Panelized wood, which is used for wall and casework covering, comes in several stains and texture finishes.
The wood ranges from Douglas fir, maple and Oregon black walnut to Pacific madrone and Oregon myrtle. Reclaimed material is sourced regionally close to the manufacturing facility. Design, saw milling, kiln drying and finishing take place under one roof.

Disaster-resiliency expert Stephen Flynn has posted a piece about the Oso mudslide on Northeastern University Seattle’s Re: Connect blog.
Flynn is a professor of political science and director of Northeastern’s Center for Resilience Studies in Burlington, Mass.
He spoke with the DJC in February about lessons from Hurricane Sandy and the need to better prepare for natural and manmade disasters.
In his post he says we tend to ignore the risk of disasters until they happen and says builders, developers and planners have a role to play in changing that.
It is purposeful denial, bordering on negligence, which allows residential property development in dangerous areas. That negligence is fed by a self-destructive cycle that begins when builders and developers with short-term interests are granted local permits to build new homes on low-lying barrier islands, flood plains, or near steep hills in the wilderness. These homes then require investments in new public infrastructure, which in turn require additional tax revenues to build and sustain. In order to expand the tax base, towns end up approving new property development adding new fuel to growth. When the foreseeable disaster inevitably strikes, individual property owners are often wiped out and the American taxpayer ends up picking up most of the tab.

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.
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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
