Event Description

Engineers and Geoscientists BC has a Council-approved Climate Change Action Plan (CCAP) which provides a framework for how it will better support its registrants in their professional practice and allow the regulatory body to respond to climate change issues proactively. In support of actions in CCAP around providing advanced education, Engineers and Geoscientists BC is pleased to offer a series of Continuing Education Events (CE) relating to advanced demand side energy management and GHG emissions reduction in existing Part 3 (large commercial and residential) buildings.

About the Event

The seminar series will enable knowledge sharing between attendees and building sector professionals with first-hand experience in deep retrofits, with a goal of removing barriers and increasing the confidence and capacity of registrants to take on existing building energy and emissions retrofit projects.

The fifth event in this series will provide electrical engineering considerations in decarbonizing existing Part 3 buildings. The webinar will provide an overview of considerations for holistic, long-term planning for current and future electrical needs and implications for load planning, utility and peak demand-side management, and resiliency. Participants can expect to learn about electric vehicle charging infrastructure, heat pumps through insights, best practices, and lessons learned from their own projects. The presents will also share their short-term outlook on how they see the market and policy landscape evolving.

Following the presentations, participants will be invited to engage with the presenters through a facilitated panel discussion.

Learning Objectives

  • Understand regulatory drivers for decarbonizing buildings.
  • Learn about the installation of electric vehicle charging infrastructure.
  • Understand current code requirements in relation to decarbonizing existing buildings.
  • Learn about project planning considerations including design and permitting.
  • Understand how to consider climate risk and resilience in electrical system retrofit projects.

Target Audience

  • Registrants working in the buildings sector looking to get engaged in electrical systems retrofit work;
  • Firms providing services in retrofitting electrical systems; and
  • Engineers and geoscientists working in the field of climate change or those wishing to learn more about decarbonization of existing buildings as a potential opportunity for climate action.
