356. Hydrogen’s role in a zero-emissions future

Alberta’s is betting big on hydrogen, but can hydrogen, blue, green or otherwise help us get to a zero-emissions future? We take a deep dive to find out how and where hydrogen can decarbonize energy use.

Deep energy retro fit transforms 1953 bungalow.

355. Deep Energy Retrofitting 1953 Bungalow to Net-Zero

The Tufts had a choice: bulldoze their 1953 bungalow and start over or do a deep energy retrofit to net-zero. They chose the cheaper option in this amazing story of renewal. 

DIY Net-Zero

348. Family’s 20-year DIY home retrofit journey ends by getting to net-zero

Darren and Darcy Crichton started their DIY home retrofit on their 1969 bungalow 20 years ago. Their goals were modest – to cut drafts and increase comfort. But with careful research, they did the right renovations in the right order and today they live in a very comfortable solar-powered, net-zero home. This is their story.

The consultants said it wasn’t affordable–it couldn’t be done. But Salvation Army architect Michaela Jones pushed back hard requoting their 175-unit supportive living complex as net-zero-ready at the last minute. Now this amazing solar powered, geothermal heated and cooled, energy-efficient building will save Sally Ann $6 million. 

Net-Zero 101 - new for 2023

340. Net-Zero 101 – Ultimate guide to cold climate homes

So much has changed in the 15 years since net-zero homes came onto the landscape. We now have heat pumps good to -35, streamlined building strategies and it now makes more economic sense than ever to build a net-zero home, eliminate your gas utility bill and produce your own energy.

309. EnergieSprong: Retrofitting 59 Homes to Net-Zero in Canada’s North

Buildings are responsible for 30-40% of greenhouse gas emissions. Edmonton builder Peter Amerongen is tackling this head-on by piloting the Dutch idea called EnergieSprong. New walls and roofs are built in a factory and craned onto old energy-inefficient homes transforming them all the way to net-zero. It’s the largest project of its kind in North America as 59 homes are being transformed to net-zero energy.

305. Three energy innovations from the journey to net-zero emissions from 2021

2021 was the year of net-zero. Nations, cities, companies, and even home builders are involved in making pledges. We look at net-zero the goal and three innovations from the journey to net-zero including an inspiring net-zero passive house, the world’s most efficient windows, and an innovative smart home energy system.

super windows

299. LiteZone R22 super windows are a game-changer for green homes

Net-Zero and passive houses may have 16-inch thick walls and R50 insulation, but what to do about the windows? After years of development, Greg Clarahan says he has the answer – super windows with unheard-of R22 insulation values. This could be a game-changer for green homes.

Net-Zero Passive House

297. Stunning Net-Zero Passive House good to -40 with no furnace

Passive House 101 – This amazing net-zero passive house has no furnace and is designed to withstand the northern Canadian winter where temperatures reach near -40 Celsius. We present the anatomy of a passive home that is 90% more efficient, is super-insulated, has no concrete foundation walls and that uses a 450% efficient heat pump water heater not only to provide hot water but also to provide supplementary heat in the cold depths of winter
