The Trees and the Forest of New Towers - The New York Times
By Stephen Wallis
Nov. 20, 2019

Mass timber refers to prefabricated structural wood components that can be used to construct buildings — even large-scale buildings — faster, with less waste and eventually with less money........Mass timber refers to a variety of different types of engineered wood components, the most common being cross-laminated timber (known as CLT) and nail-laminated timber (or NLT), in which multiple layers of wood planks, stacked at 90 degrees, are glued or nailed together under pressure to form structural panels. So-called glulams, which are made in a similar fashion and have been around for more than a century, are typically used for long elements like beams and columns.........building with mass timber can ameliorate climate change because it produces less in greenhouse gas emissions than construction with concrete and steel. And wood has the benefit of storing the carbon dioxide trees absorb during their growth, keeping it out of the atmosphere indefinitely.....While cutting down trees to make buildings may not sound environmentally sensitive, mass timber supporters argue that wood could be harvested from sustainably managed forests...At the end of last year, the International Building Code was changed to allow wood buildings of up to 270 feet tall, or the equivalent of about 18 stories, from 85 feet....People want to live and work in these kinds of buildings — they have a sense of connection to the material,”......what we’ve seen from fabricators and builders is that there’s a 35 percent drop in construction time for mass-timber buildings, which means the carrying costs are less.”....

Log Cabins? No, These Wooden Buildings Are High-Rises
Jan. 1, 2019 | The New York Times | By C. J. Hughes.

"But proponents scored a huge win last month when the International Code Council, an influential advisory group in Washington, concluded that some wooden buildings could climb as high as 18 stories, more than twice the current permissible height, without compromising safety."....."In addition to their green benefits, he said, wood buildings perform well in earthquakes because of their lighter weight and flexibility.".....Proponents of wood must still overcome a longstanding bias. In the 1800s, fires were a scourge, prompting restrictions on wood. But steel is not infallible and can buckle in extreme heat, ....“But we’ve gotten comfortable using steel and concrete products, so the question’s been, ‘Why would we change?’” ....Still, wood is not what it used to be. The decline in old-growth forests means developers can no longer count on huge single trunks to support floors. Instead, they rely on mass timber, an engineered product made of layers of spruce or fir pressed together in a way that is similar to plywood but with a more elegant look......Wood remains expensive, but the assembly-line aspect of mass-timber production, in which factories make large panels, then assemble them on-site, saves time and labor costs......

Five things the TD Centre can teach us about how to build Toronto - The Globe and Mail
The Globe and Mail
Published Friday, May. 01 2015,

The TD towers were a radical departure both in scale and in style. The tallest of the original two soared to 56 floors, dominating the skyline like nothing before or since. Rising from its six-acre site at King and Bay, it was everything the old buildings around it were not. While they featured arched windows and gargoyles, Greek columns and bronze roofs, the design of the TD Centre was all austerity and simplicity.

It is just this sort of future that the creators of the TD Centre had in mind when they hired one of the era’s most renowned architects to build them something outstanding. The architect was Ludwig Mies van der Rohe (1886-1969), the Chicago-based German émigré who liked to say that “less is more.” He referred to his works as “skin-and-bones” architecture, and his unadorned steel-and-glass boxes were meant to reflect the spirit of a modern technological era.

It took ambition and foresight to pull off something as bold as the TD Centre. It meant thinking about what the city would become instead of just coping with what it was. Those qualities sometimes seem lacking in today’s Toronto. There are still things we can learn from those dark towers.

First, don’t be afraid of tall buildings.
Second, investing in quality pays.
Third, maintain what you have.
Fourth, pay attention to details.
Finally, always think about the future. Toronto, and Canada, were in a risk-taking frame of mind when the first tower took shape. Expo 67, the wildly successful world’s fair, was under way in Montreal. The striking new Toronto City Hall by Finnish architect Viljo Revell had opened two years earlier.

Toronto has finally found the confidence to act like a big city - The Globe and Mail
The Globe and Mail
Published Wednesday, Mar. 18 2015

Toronto has finally found the confidence to act like a big city.

Back in the 1970s, Toronto was so fearful about density and development that city hall slapped a temporary 45-foot (13.7-metre) height restriction on new construction in the downtown core. Over time, planners have come to understand that if the region is going to absorb hundreds of thousands of newcomers without succumbing to endless urban sprawl, it will have to grow up rather than out. Now the boom in condo construction and the vogue for downtown living has made it possible to build a denser, livelier urban core. If central Toronto is starting to feel even a bit like Manhattan, it can only be a good thing.

20 Small Businesses of the Future: Vertical Farming - BusinessWeek
Vertical Farming
The Idea: Local food in growing cities

Stage: Buzz words and pretty drawings

Single-story, high-tech greenhouses save significant amounts of water
and increase productivity. So why not stack them up and makes cities
self-sufficient? The idea for vertical farms came from an infectious
disease ecologist, Dickson Despommier, who turned his knowledge of
parasites into a way of looking at cities. "Instead of the city behaving
like a parasite, it should be a symbiant," Despommier says. "The future
city has to take a big lesson from nature and start behaving like an
ecosystem." By that, he means zero-waste cities: Even the idea of waste
is anathema to a working ecosystem. So Despommier envisions skyscrapers
of the future producing the majority of food consumed by citizens, with
brown water and food compost used for farming. "City life," says
Despommier, "demands city food."

The Vertical Farm by Dickson Despommier Argues for Farm Skyscrapers -
SEPTEMBER 25, 2010 | Wall Street Journal In his new book "The
Vertical Farm" (St. Martin's, 2010), Dickson Despommier, a professor of
environmental health sciences at Columbia University, argues that in
order to feed the cities of the future, we will need to learn to conduct
agriculture in a new way—vertically. Specifically, he proposes building
farms in skyscrapers, so as to use less land and to waste fewer
