We detail the journey to decarbonize 11 existing office towers in downtown Vancouver through the Zero Carbon Building – Performance Standard. This session will outline the development of a long-term energy plan to achieve net-zero site emissions by 2040, focusing on the implementation of heat recovery systems that optimize the facilities’ thermal assets. Take a deep dive into Pacific Centre Mall’s implementation strategies, including heat recovery chillers that provide low-carbon heating, interconnected towers to balance thermal loads, and phase-change thermal storage to manage cooling and heating asymmetries. Discover the challenges, solutions, and key lessons from one of Vancouver’s most ambitious decarbonization projects.
