What if your\u00a0community provided a greener, more efficient, more reliable source of heat using locally sourced energy? What if it didn't take up space in your home or office building, you didn't have to maintain it, and it was just about guaranteed to keep running and keep you warm through big storms and power outages?<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">That's the promise of district energy systems \u2014\u00a0along with climate benefits that have earned them an endorsement from the United Nations Environment Program. World leaders meet Dec. 2-13 for the COP 25 UN climate conference in Madrid to discuss next steps in implementing the Paris Agreement to reduce greenhouse gas emissions and curb global warming, and district energy is one potential tool.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The idea is that instead of having an individual heating and cooling system for each building, multiple buildings are hooked up to a single, central system \u2014\u00a0similar to the idea of hooking into a municipal water service instead of each building relying on individual wells. The heating and cooling is\u00a0distributed to individual buildings through pipes that typically contain heated or chilled water.<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/i.cbc.ca\/1.5378748.1575055980!\/fileImage\/httpImage\/image.jpg_gen\/derivatives\/original_780\/district-heating.jpg\" alt=\"\" \/><\/figure>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">It's not new \u2014\u00a0some district energy systems in Canada are more than 100 years old.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">But thanks to environmental concerns and the desire in\u00a0communities to use greener energy technologies for heating and cooling,\u00a0<a href=\"http:\/\/cbc.ca\/1.5379125\">new projects are popping up across the country<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">\"Yes, there's a real renaissance,\" says Bruce Ander, president and CEO of Markham District Energy in the Great Toronto Area.
