“ WE ’ RE IN A RACE AGAINST TIME TO HIT THE PROVINCIAL AND FEDERAL EMISSION REDUCTION TARGET , WHICH IS BASED ON THE PARIS AGREEMENT , SO WE NEED TO TRANSITION TO ZERO CARBON AS SOON AS WE CAN ”

with heating .” Aside from utilising sustainable energy , such measures have the knock-on effect of improving the experience of citizens , as with the natural light provided by daylighting . “ These are the types of things that we also look at . It ’ s not just about energy effects , but also occupant comfort .”
Such measures are to play a vital part in achieving the city ’ s ambitious Zero Carbon Transition Plan . “ The provincial government has set a target of 30 % emissions reductions by 2030 , and the federal government has set an 80 % reduction target by 2050 , which is in line with the Paris Agreement to limit the global temperature rise to 1.5 degrees Celsius by 2050 . Our Zero Carbon Transition Plan is predicated around these targets . We ’ re looking at reducing our energy use for new and existing buildings by 30 % by 2030 . We ’ re targeting various measures : heating , ventilation , air conditioning systems and building envelope . We ’ re going to use heat recovery : recycling waste heat wherever possible . Once you get the energy demands of the building down , then the next step is to look at renewable technology . That ’ s the most efficient way to approach it . It ’ s energy management 101 .” Other innovations geared towards meeting the city ’ s targets include innovations in passive heating . “ The SolarWall is a matte black surface that can be put on top of a building ’ s exterior wall , leaving an air gap ,” says Liang . “ The sun hits this black surface , and transfers energy to the wall and air gap . The air is heated in that gap and then brought into the building to preheat the air for ventilation . “ We expect to verify the energy savings
