How drones are heat mapping high-rise energy guzzlers
Posted August 13, 2019
Drafty high-rises are the gas guzzlers of the building world and infrared drones are swooping in to spot costly energy leaks
It’s a fact of high-rise life that’s become all too familiar to legions of urban condo dwellers: many apartment buildings leak like sieves, with heating or cooling seeping out through poorly sealed windows, cracks and concrete balcony slabs.
Yet those construction flaws, in the aggregate, add up to something much larger and more problematic. By most estimates, buildings today account for about 40% of all carbon emissions, and therefore play a huge role in the accelerating climate crisis. We should be thinking of all those drafty apartments as if they were gas-guzzlers spewing carbon and other harmful gases into the atmosphere.Continue Reading...
Building innovation: Going green pays off for one of Canada’s Big 5 banks

Buildings account for roughly 20% of Canada’s carbon footprint - CIBC is banking on shrinking theirs
In the expanding world of energy-efficient commercial buildings, designer projects with LEED certification and cutting-edge architecture tend to win the awards and garner public attention. But a pilot project involving 30 lowly bank branches, most of them stand-alone buildings, has shown how smart interventions can reduce emissions and operating costs with a brisk payback period.
Keeping our buildings lit, heated and cooled accounts for 20% of Canada’s greenhouse gas emissions. In some provinces, emissions from buildings are growing faster than every other source except transportation. If Canada is to meet its 2030 GHG targets, older buildings, which make up three quarters of this nation’s built form, will need to be retrofitted over the coming decade.Continue Reading...
Smart buildings: how AI is slashing heating and cooling bills

With artificial intelligence analytics and wireless sensors, buildings are growing smarter - and closer to zero footprint
In the nerdy world of smart thermometers, every self-respecting tech geek knows precisely how easy it is to undermine the intelligence wired into these devices: Just press the manual override.
For several years, the so-called HVAC industry – heating, ventilation, air-conditioning – has been turning out increasingly sophisticated programmable thermostats with a range of features designed to allow users to adjust a home’s temperature automatically (including smartphone apps that let users make changes remotely). However, the promised energy reductions and related savings associated with the set-and-forget features go right up the chimney when an occupant decides the dwelling is too hot, too cold or too stuffy, and intervenes. Depending on the device, the settings may not revert, paradoxically enabling all the carbon-wasting inefficiencies these devices were meant to prevent.Continue Reading...
The Canadian artists creating a better world

Top creators are flipping the script by mixing environment and ethics into mainstream entertainment
In the mid-2000s, with gravel quarry operators moving aggressively to carve huge aggregate mines out of southern Ontario’s limestone moraines, folk singer Sarah Harmer recorded a song titled, simply, “Escarpment Blues.”
If they blow a hole in the backbone
The one that runs cross the muscles of the land
We might get a load of stone for the road
But I don't know how much longer we can stand…
Harmer grew up near Mount Nemo in north Burlington – a dramatic craggy outcropping on the Niagara Escarpment, which is a UNESCO World Biosphere Reserve. The damage being inflicted on the area’s delicate flora and fauna fired not just her indignation, but also her creative imagination.Continue Reading...
Race to the stars
Posted November 19, 2018
Companies, regulators and investors are competing to get their hands on carbon emissions data from satellites.
Going back to his childhood, Stephane Germain, the founder of Montreal-based GHGSat, dreamed of figuring out how to pursue a career that combined space, technology and the profit motive. After completing his graduate work in engineering physics, he found himself drawn increasingly to both the world of commercial satellites and the scientific challenge of using specialized orbiting sensors to measure atmospheric greenhouse gas concentrations.
But when the province of Quebec prepared to join California’s cap-and-trade system, “the light bulb went on,” Germain says. Cap-and-trade forces companies to buy credits for the right to pollute, which incentivises them to reduce emissions. Pondering the logic of such systems, he realized the province’s industrial emitters suddenly would be forced to manage their emission risk and therefore had a financial incentive to seek out better information about the carbon leaving their facilities. “I knew there was market demand,” he explains.Continue Reading...
