The goal of many modern supply chains is to become more sustainable and reduce its carbon footprint. A great way to do this is by retrofitting older warehouses to reduce energy usage.
Unfortunately, this is often a costly initiative. These facilities are old and deteriorating, and investing in expensive green technology is sometimes a poor investment. How can these facilities be improved to become more sustainable without breaking the bank?
I sourced four experts to discover the answer to this very question: Sean Canning, LEED AP and owner of 10|70 Architecture; Shawn Casemore, supply chain consultant President at Casemore & Co; Dan Gould, president at energy-efficiency firm Synergy; and Dave Homerding, marketing manager of commercial contracting and roofing company WeatherSure Systems.
Based on their conversations, here are nine affordable retrofits to can help make the warehouse more sustainable.
1. Use solar tubes to increase natural lighting -- Solar tubes, or light pipes, can introduce natural lighting through skylights without major construction that will impact the building’s integrity.
2. Apply a cool roof -- White, reflective coatings can be applied to roofs to reflect UV rays and reduce the amount of heat the warehouse absorbs.
3. Upgrade batt insulation to sprayed-foam or loose-fill -- Loose-fill and sprayed-foam insulation are much more effective at insulating commercial facilities, and can be installed with little financial investment.
4. Move to task-lighting to reduce usage -- If intense lighting isn’t necessary to perform routine operations in the warehouse, reduce electric ambient lighting, introduce natural light and use “task-lighting,” or localized light around areas that need increased visibility.
5. Upgrade metal halides to fluorescent, induction or LED lights -- These lighting fixtures are much more efficient than the traditional metal halide lights used and warehouses, and can often be paid off in only a couple years of energy reduction.
6. Purchase destratification fans -- Destratification fans circulate heated air in warehouses, and can greatly reduce the amount of energy exerted to heat facilities.
7. Deploy (or program) networked thermostats -- Again, energy exertion can be reduced using controllable thermostats that eliminate extraneous heating and cooling cycles.
8. Use daylight or motion sensors to reduce light usage -- If electric lighting is necessary, invest in motion sensors to only use lighting when workers are present, or daylight sensors to dim lighting according to the natural sunlight throughout the warehouse.
9. Join a energy-reduction demand-response group -- Finally, participating in a peak-energy response group can reduce energy and add extra cash-flow to the business.

In February of 2010, I wrote this story about an office building in Georgetown that was constructed of reclaimed cargo containers. The owner, Jay Stark, said it was the first project of its kind in the country. I also produced this video-tour of the space at the time. Here is our story from Dec. 16 about the sale.
Now, nearly two years later, the space is for sale for $1.5 million. Sadly, it was a foreclosure. I
The slight upside is that it will be really interesting to see who buys the site when it sells. I recently spoke to Evan Lugar of Kidder Mathews, who is representing First Savings Bank Northwest on the sale. He said the bank has owned the property since August. He also said it's a tricky space to sell because it isn't typical retail or commercial and is unique. He's targeting creative businesses.
The building is made of 80 percent recycled materials by weight. The complex has two buildings, which are each made of six cargo containers that came from the Port of Seattle. They have halogen and fluorescent lighting, an efficient reverse-cycle chiller HVAC system, and windows with argon gas sandwiched between the panes for increased insulation. There is a rooftop deck with views of downtown Seattle and Mount Rainier.
Typically - the super green, innovative projects that have been built have been created with the intent of the owner using it for many years. (Houses don't count). The greenest commercial projects I've profiled over the years have been built or are being built by the Bullitt Foundation, the U.S. General Services Administration, a consortium involving the city of Portland, universities or by firms that intend to stay in a space for a long time.
My point is: they don't turn hands. Because of that, there isn't much information about the resale value and market for super green projects in the U.S. created for a specific client. People hypothesize uber-green buildings hold their value better and that there's more demand, but it's hard to prove - without proof. No matter what, this is just one building. But the more sales we see, the more accurately we'll be able to guage the true value of innovative sustainable buildings and whether it's the LEED credential or a building's inherent sustainability that translates as value.
As a sidenote, this is the second time spaces made of cargo containers or using "cargotecture" has been in the news in a week. Earlier this week, the DJC covered a new pilot project Starbucks drive though in Tukwila made of cargo containers. Here's our story and here's the story the AP ran based on our story.
This week, the Bullitt Foundation's Cascadia Center for Sustainable Design and Construction released a report detailing its energy performance metrics. For all you energy nerds out there, this is a pretty exciting development.
The document outlines how the six-story building will meet net-zero energy. The big
highlight is that it releases the planned EUI of the building, or Energy Use Intensity. An EUI score is expressed in units of thousands of BTUs per square foot of gross floor area. Based on 52,000 square feet of gross floor area, the project should have an EUI of 16. Based on 39,000 square feet treated floor area, a common European measurement, it would have an EUI of 21.
I was recently discussing EUI with members of a ZGF team. They told me the average EUI for an office building in the Pacific Norhtwest is 106.
The report also says the U.S. Department of Energy's Zero Energy Building database currently contains no comparable buildings.
The report includes a pie chart with sections for the center's different energy uses. The largest percentage at 23 percent will feed lights. The next highest amount of energy, at 10 percent are pumps. About 9 percent of the building's energy will feed monitors while 8 percent will feed workstations. Toilets will get .2 percent of the building's energy use.

P.S. The Bullitt Foundation is hiring an administrative and grants assistant. The job description is here.
This week, I toured King Street Station. For those of you who aren't aware, the 1906-built-station is in the midst of a $50 million renovation. The project is absolutely, totally and utterly incredible.
The main thrust of the project is a much needed seismic renovation. Seriously, the tons of steel being put into this project are indescribable. But King Street Station is also a historic building and must be maintained as such. Once the rehabilitation is complete, it will be very sustainable: it's on track to meet LEED platinum, up from a goal of LEED silver. Last year, the project's sustainable efforts were honored by AIA Seattle with a gold level award from the What Makes It Green event. ZGF Architects is the architect. Sellen Construction is general contractor.
Obviously, the most sustainable thing about the project is the fact that it is a historic renovation of an old structure, which retains the embodied energy inherent in the building. But the team went much further. Geothermal wells in the building will likely provide all heating and cooling. The main waiting room will return to its 100-year-old state of being naturally ventilated. Incredible effort has been spent to save, clean and better old building materials. All of these elements will be detailed in a future DJC story.
For now, I'll whet your interest with some photos of the space. As you can tell, I got to tour the inside of the clock tower, which is not part of the current project's phase. However it is really cool. To see more photos of the clock tower or tour, follow my page on Facebook here. And if you haven't voted for this blog yet as best of the web, please do so.

Painting is a fun, easy to do project. But once the job is done, excess paint often sits in the basement, dying a slow, slow death as the years pass by.
So today I was delighted to hear about "the green man," via a press release. The green man is an
effort by Wallingford's Reed Painting Co. to gather all your old paint and recycle it. Each year, it says, at least 695,000 gallons of paint is wasted in Washington State.
Currently, King County suggests residents dry out latex paint, strain it and put it in the garbage with the lid off. But Cole Palea of Reed Painting said that wastes a good product, while taking up valuable landfill space. Instead, his organization is collecting paint, straining it, categorizing it by color and giving it away as recycled paint.
"The need is there," he said. "But there is no real solution out there. We're hopefully getting this conversation started around the community."
This is the second year Reed has held a paint drive. Last year, it collected almost 200 gallons just from Wallingford, Queen Anne and Capitol Hill. The drive is currently in its second week. Palea said Reed has already doubled the amount of paint it collected last year and plans to pick up an additional 200 gallons of paint this weekend, for a total of at least 600 gallons that would otherwise be in the landfill.
People can either drop off old paint at the Reed shop in Wallingford or call to schedule a $20 pickup this weekend.
Palea said he and business owner Randy Reed grew up in Hawaii where they were acutely aware of natural resource use. Palea is a certified sustainable building advisor and this effort is one way for Reed Painting to become a better steward of the environment. "We're not trying to greenwash and tell everyone we're 100 per cent green by no means, because we're not. But we're definitely taking steps further," he said.
Portland has successfully turned paint recycling into a business. To read more about that city's efforts, check out this excellent story from 2009.
Reed is a painting contractor that works on homes and commercial projects. It paints the interior of the Seattle Art Museum between exhibits.
To drop off your paint, visit the shop this Monday through Friday from 9 a.m. to 5 p.m. It is at 3668 Albion Place North, on the backside of the block. The front of the shop is along Woodland Park Avenue North and 38th. There are three garage doors painted red. Reed is behind the first garage door.

Just got a press release on a new home built of cargo containers that is being craned into place today. The home, called "cargotecture c680," is on Whidbey Island.
The 680-square-foot project is made of four cargo containers and is multi-stories. It is expected to be complete and holding tours in February. It will have a living space, large view deck, green roof,HyBrid Architecture.
This is the second house in a month the firm has been involved in that's been craned into place. The other, a home for Rob Humble of Hybrid, was developed by GreenFab and craned into place last week. However that project was built of modules, not cargo containers. To read that story, click here.
The press release says that the house is located on a beach that looks over container ships passing throuhg. "The containers HyBrid used for the project were almost certainly on those ships at some point in the past decade," the release says. Isn't that poetic?
I've been through about an eighth of the GreenBuild Exhibition floor so far and wanted to share two of the things I've seen with you.
These are the Sanyo bifacial panels that will be on the Bullitt Foundation's Living Building on Capitol Hill. The collect energy from both sides while letting some light in at the same time. Bullitt was attracted by the transparency of the panel.
And this is the BioNova Natural Swimming Pool. The swimming pools use natural systems (meaning plants in gravel) instead of chlorine and other chemicals to treat water. That means the water color is darker, looking more like a lake than a traditional pool. It also means that people that use them need to get used to the idea of sharing their pool occasionally with frogs or other critters. James Robyn, CEO of the company, said the pools aren't for everybody. "Whoever doesn't like that sort of thing shouldn't do this."
Robyn said the pool technology came from Europe, where it has been used for 20 years. He said it has a low carbon footprint, is all natural and is "perfectly healthy." Robyn, who is based in New Jersey, said he's being asked about the pool system all across the country. In fact, he was in Seattle giving a lecture last month though he said there are not yet any of his pools in process in the Seattle area.
There are basically five ways to build the pools but each involves about 1 square foot of treatment space for 1 square foot of pool. That means if you want an 850-square-foot-pool, you need 850 square feet of treatment space. It's more expensive but it certainly looks cool!

Yesterday, King County launched a video series called 'EcoCribz.' The series follows one family as they green-remodel their house and aims to teach viewers - you and I - valuable lessons while aiming us towards other green remodeling resources.
The first video, available here, profiles the Bangs family and their Issaquah home. It's a fun tour that
Patti Southard, project manager for King County's GreenTools Program and host of the series, said King County wanted to show people that green home remodeling creates healthy, comfortable spaces that can save money, increase home value and help protect the environment. The county also created helpful remodel tips for renters who are looking at paint and interior options like area rugs and eco-friendly bedding.
The series also illustrates how homeowners can use the county's Eco-Cool Remodel Tool, another useful resource. Basically, it's trying to get you to think about your choices before you remodel or build to create a greener space.
