But it\u2019s not like every other house on the block: the 900-square-foot house, located in Edmonton\u2019s Glenora neighbourhood, is net zero, which means it consumes as much energy as it produces.<\/p>\n<p>Tufts, a mechanical engineer, and his wife, Jena, a development engineering manager, purchased the 1950s-era\u00a0two-bedroom box bungalow in 2011 for $400,000. They liked the location\u2014within biking distance of downtown Edmonton\u2014and the big backyard. But after their first winter, they realized that the home\u2019s postwar construction couldn\u2019t keep the cold out; in Edmonton, temperatures regularly dip below -20 degrees Celsius. Blankets would freeze on the bed if they were too close to a wall. Frost formed on the ceilings, and condensation froze on the windows. Any time they stood next to a wall or a closed window, they could feel the cold. The couple replaced the windows, sealed baseboards with spray foam and added insulation to the basement\u2019s bare concrete walls, but the house was still too cold whenever temperatures plummeted.<\/p>\n<div id=\"attachment_1242512\" style=\"width: 1930px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"wp-image-1242512 size-full lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/Jesse-Tufts-old-home.jpg\" alt=\"\" width=\"1920\" height=\"1440\"\/><\/p>\n<p class=\"wp-caption-text\">The original home, built in 1953<\/p>\n<\/div>\n<p>By 2016, the house needed more upgrades. The asphalt shingles on the roof had begun to peel, and things were getting cramped: Tufts\u2019s sons, aged nine and four, were sharing a room. The couple planned to replace the original roof and add dormers\u2014small rooms that jut out from the roof\u2014to squeeze some extra square footage into the house. But when Tufts asked a carpenter friend for his opinion on the renovation, he was told that he might as well rip off the roof entirely and build a new second storey.<\/p>\n<p>The two used software to play around with different configurations. They realized that with enough insulation, it would be possible to cut off natural gas entirely and heat the house only with electricity, turning the scr<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>y bungalow into an energy-efficient, solar-powered dream. Tufts was thrilled: as a self-described \u201cgearhead,\u201d he already had an interest in EV-powered cars, and he once converted a Japanese mini-truck to battery electric and learned how to home-brew biodiesel to run cars on vegetable oil. He decided to do it.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242519 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/af255175-0fbb-47e5-a772-cbc20595ef8f.jpg\" alt=\"\" width=\"1328\" height=\"747\"\/>At the time, Tufts was working in R&amp;D at a window and door manufacturer. He realized that every time a customer wanted a door with a window cutout, the company had to remove and throw away a piece of fibreglass foam insulation. He came up with the idea of gathering and upcycling the door cutouts to use as insulation for his own house. He added three layers of this insulation, bringing the energy load of the house so low that it could be heated with the power equivalent of four hair dryers on the coldest day of the year.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242513 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/20181208_090708_HDR.jpg\" alt=\"\" width=\"1920\" height=\"1080\"\/>With a proposed budget of $100,000, he hired Butterwick Construction, which specializes in building net-zero homes, to begin rebuilding the second storey in August of 2018. The family camped out in the basement until construction was finished, and built a temporary wall blocking off the front door so builders could come and go without disrupting family life.<\/p>\n<p>Once the structure was built, they wrapped the house in an exterior airtight barrier, which resembled a giant Gore-Tex jacket, to keep out the rain and wind. They sealed over the original walls on the main floor and added new walls and windows that went all the way up to the attic and right down to the foundation.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242520 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/IMG_6184.jpg\" alt=\"\" width=\"1280\" height=\"960\"\/>Tufts focused on longevity when it came to upgrades, spending $36,000 on durable Hardie fibre cement siding and installing a metal roof instead of a shingled one to avoid future repairs. The builders added a 12-kilowatt solar panel system onto the roof, which generates about 13,000 kilowatt hours of energy a year\u2014more than the family uses by 3,000 kilowatt hours. \u201cWe\u2019ve been net positive since we turned the system on,\u201d Tufts says. In the winter, when there\u2019s less sunlight, their energy bills can cost up to $300 a month, but they receive roughly the same amount in credits during the summer. After adding up the credits he received over the course of a year, Tufts realized that the power company actually paid him $500. The house is heated by a $12,000 air-source heat pump that extracts heat from the outdoor air, even in the winter.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242521 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/20190527_171912_HDR.jpg\" alt=\"\" width=\"5312\" height=\"2988\"\/>Even though the cost of the finished project stretched beyond $350,000, Tufts estimates that only $50,000 was directly related to the efficiency upgrades. The extra insulation and solar panels they added ended up costing far less than the siding and the metal roof. The family also took advantage of generous government rebates, getting $11,000 back from the Efficiency Alberta program on the $27,000 solar-panel installation, as well as $8,000 back from the Canada Greener Homes grant on the entire renovation.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242514 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/Jesse-Tufts-home-deck.jpg\" alt=\"\" width=\"1920\" height=\"1440\"\/>Now, post-retrofit, the family has much more space\u20141,850 square feet compared to 1,350 before the renovation, and four bedrooms instead of two. It\u2019s also much more comfortable. \u201cYou don\u2019t really notice a difference until you go to someone else\u2019s house and you sit by a window and think, T<em>his is cold and drafty<\/em>,\u201d Tufts says. \u201cEvery square foot of our house is the same temperature.\u201d The thick insulation has also created a sound barrier: traffic noise rarely makes it inside the house.<br \/>\n<img loading=\"lazy\" decoding=\"async\" data-sizes=\"auto\" class=\"aligncenter size-full wp-image-1242515 lazyload\" src=\"https:\/\/www.macleans.ca\/wp-content\/uploads\/2022\/12\/DJI_0570.jpg\" alt=\"\" width=\"4900\" height=\"3264\"\/>Perhaps the most surprising aspect of the net-zero retrofit, Tufts says, was how easy it was to accomplish. \u201cEven though I\u2019m an engineer and was already involved in efficiency work, I thought it would be difficult,\u201d he says. Achieving net zero was a ladder of opportunity, he says. \u201cOnce you get to the next step, you realize all these things become possible.\u201d<\/p><\/div>\n<p><script async defer crossorigin=\"anonymous\" src=\"https:\/\/connect.facebook.net\/en_US\/sdk.js\"><\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
