Meanwhile, the ordinance’s continued suspension provides more time to develop a market for materials recycled from deconstructed houses. Selling those materials helps reduce the higher cost of deconstruction.

The National Association of Home Builders reports that 58,600 houses were removed from their lots in 2017 to make way for newer, almost always larger, houses. Many of them were obsolete places that nobody wanted, and the land under most was probably more valuable than the houses themselves. But instead of being demolished, at least some could have been deconstructed: taken apart systematically so their parts could be reused.

Advanced sensors and AI that can detect quickly and determine accurately what can be used among CDW and efficient robotic sorting could aid circular construction by vastly improving the recycling of a wide range of materials. The focus should be on the smart dismantling of buildings and ways of optimising cost-effective processes.

“In a demolition project, the entire building is demolished and wrecked,” said Olivia Cashman, construction and waste specialist with Hennepin County. “Whereas in a deconstruction project, the building is taken a part and it’s typically by hand so that process typically takes a lot more labor and time.”

A 2017 UN Environment report estimated the building sector contributes 49 percent of global greenhouse gas (GHG) emissions thus making it the single largest contributor to climate change. Globally, building operations account for 28 percent of GHG emissions and the embodied carbon of building materials–the emissions generated in the production, transport, and assembly of materials such as wood, concrete, and steel–accounts for another 11 percent.

Jeremiah Logemann rummages through a storage locker Friday to show off some of the parts from the St. Raphael steeple that he plans to turn into pieces of art. St. Raphael in Downtown Madison was destroyed by fire in 2005. Since its demolition in 2008, the steeple has been kept in a lot along East Washington Avenue, but Logemann assumed ownership of the spire in June when the Madison Diocese was looking for a way to dispose of the 18-ton structure. STEVE APPS/STATESMAN JOURNAL
“I’ve been busy as hell since that day. It’s kind of miraculous,” Logemann said. “There are a lot of people in Madison that either just want art to make their place look cooler or they like the story of the steeple or a barn or they’re philanthropists. It doesn’t matter where their heart is at. We’ve got the material and I have the drive to make it. We can make great public art all over this city.”

If the salvageable material from deconstructing your house is worth hundreds of thousands of dollars, you should not need to pay somebody to take the house apart so that you can give the pieces to charity. There should be people waving money in front of your face to come in and take it apart.
For about six months last year, the St. Louis Development Corporation hired workers to carefully take apart a former storage warehouse in the Vandeventer neighborhood and saved lumber, brick and other materials for reuse.

“Each job is like a cadaver. You get to dissect the building, see how it was put together, how it worked, how it could fail,” Schwarz said. “And each job is different. You don’t always know going into it what exactly is going to be there.”
Dismantling a historic barn is an exacting process, requiring weeks of logistical planning. Because the team hopes to repurpose every piece of wood, most work is done by hand, with the occasional support of heavy machinery. “The barn has its own plan,” says manager Anthony Saraceno. “There are always surprises.” Photo by Joe Polillio
Each salvage job is unique. In the case of Pitney Farm, a portion of the grounds is to be converted into a public park. Some of the salvaged wood was set aside to build benches for the park. Real Antique Wood will repurpose the rest. “I’ve probably made 25 mantels from the beams of that barn already,” says Anthony Saraceno, who manages the mill and Real Antique Wood.

‘To me, this indicates the need to further question the current practices of the construction sector. How is it that something so simple and obvious as keeping reusable resources intact and in circulation can have become so complicated to put into practice?’
The crews carefully deconstruct old homes to rescue as many reusable materials as possible, including old growth timber.

Throwback from 2015.
From the chapel, more than 250 tons of material was reused or recycled with almost 85 percent diversion, and nearly 700 tons of material was reused or recycled from the laundry with a 73 percent diversion rate. Overall, the three buildings totaled 1,717 tons of material of which 1,246 tons was reused or recycled, making the project a successful venture.
Policies worldwide recognize that the construction sector needs to take immediate action to reduce greenhouse gas (GHG) emissions, tackle the climate crisis and limit resource depletion, with a focus on adopting a circular economy approach in construction to ensure the sustainable use of construction materials.
Instead of simply knocking buildings down and sending the CDW to landfill, circular construction would turn building components that are at the end of their service life into resources for others, minimizing waste.

Homes along Laukahi Street with Hawaii Loa Ridge homes in the background, 2015. The City and County of Honolulu could pass a law to require better use of teardowns.
Seeing the pile of rubbish that was once a house made of beautiful clear heart redwood, I could not help thinking about the environmental activists, U.S. National Park Service and U.S. Forest Service staff who have worked for decades in California to save the remaining giant redwoods from logging, while here in Hawaii we are using them for landfill. There was a significant value loss as well since similar redwood boards (8-feet-by-8-feet) would cost at least $50 each if bought locally.

The majority of council members said Wednesday that they plan to approve the ordinance, and Commissioners Jo Ann Hardesty and Chloe Eudaly said they would like to see a more severe penalty for violators. A first offense can lead to a fine of up to $500 and a third or more can be up to $1,500. “I support everything else, but I think if you’re going to hold people accountable, they’ve got to feel it,” Hardesty said. “This is not something that they’re going to feel.”

Buildings like the vacant row houses in Baltimore can be demolished, but they can also be deconstructed to salvage the materials. The salvaging process requires much more time and labor than demolition. For Baltimore – a city with an unemployment rate of nearly 5%, climbing up to 15% or more in some neighborhoods, and a poverty rate nearly double the national average – this presents an opportunity.
Prasad would like to see architects ‘go for it’ even without the requirements of the London Plan. He said: ‘Circular economy applies to buildings of all scale and all types, and I would love to see it being applied to smaller buildings than the threshold indicates at the moment.’ He said this was not ‘a glum duty’ or ‘dreadful imposition’. ‘It’s a fantastic opportunity to innovate and think in different ways. And the lovely thing is, it can be done on so many fronts. As the name implies, the circular econo

The idea works like this: before an abandoned building is torn down, crews salvage all the materials they can get from it – like wood – and keep it out of landfills. At the same time, they give the people who live in those neighborhoods the job of doing that. “It gives you a new sense of your community,” said Baltimore native Kobe Bland, who works at Brick and Board. “You start to view your community a little different because you see the potential of what could be.” What started out as the “Baltimore Wood

As resources become scarcer, building owners may one day be able to sell walls, ceilings and floors to other developers, instead of demolishing them.
In practise, circular construction is all about the “connections, joints and system layers,” says Guldager Jensen. For example, windows might be attached using a mechanical method rather than glue, or lime mortar might be used rather than concrete mortar.“It’s about being able to think about the mechanics and being able to do it in reversible ways.”

From an energy perspective, it saves about 95 percent of the energy that would be required to produce the same materials, and it also has major implications for waste reduction, job creation, and historical preservation. The Home Resource-led deconstruction of the Missoula Mercantile building in 2017 is a great example of deconstruction in our community. It diverted hundreds of thousands of board feet of old-growth lumber away from the landfill and reintroduced it into Missoula’s economy.

Since 2016, one-fourth of whole houses that were taken down in Palo Alto were deconstructed instead of demolished. This means workers were required to disassemble structures so materials could be recycled. The new policy intends to bring the successes of deconstruction to a city-wide scale. The ordinance will impact approximately 114 projects annually, according to a City Council Staff Report.

“You have a grassroots momentum for something like deconstruction, and you have a massive industry against it,” says Sara Badiali.
The building material reuse consultant thinks regulations are an effective way to make a change. Yet, she has searched the world and “can’t find any place that actually has the words ‘building deconstruction’ in legislation.”
Badiali worked with the city of Portland, Oregon, to create the nation’s first reuse ordinance. Now, Portland homes built before 1916 must be evaluated for deconstruction. Other cities like San Francisco and Milwaukee are drafting their own ordinances.

Over the past few years, and with sustainability in mind, MRA has given preference to certain building materials. It also encourages deconstruction over demolition when possible, even if doing so costs a little more.“We’re constrained by state law on how we can spend our funds, but if you take the facade improvement program, one of the underpinnings of that is sustainability,” said MRA director Ellen Buchanan. “Our deconstruction policy is also huge. The city can’t require deconstruction, but we can.”

The Auckland region is in the midst of a major building boom. Whilst this is good news for new homebuyers, it generates a lot of waste that usually ends up being sent to landfill.
The council is working to adopt a deconstruction and soft strip approach as a standard. The deconstruction methodology sees buildings carefully taken down, bit by bit, to recover materials so that they can be re-used elsewhere. This can include building fittings and fixtures, such as seating, light fittings, kitchen and bathroom sinks, as well as important building componentry and materials such as trusses, timber, corrugated iron, and steel.
