39CE - Lessons from Net-Zero Retrofits

24 May 2018 4:00 PM - 5:30 PM

This session is being offered on Friday, May 25, 2018 from 4:00 PM - 5:30 PM.

1.5 ConEd Learning Hours

Achieving net-zero energy for existing buildings through retrofits poses different challenges compared to new construction. Through WSP’s work with the OAA headquarters, and with carbon neutral feasibility studies for Public Work and Government Services Canada’s (PWGSC) portfolio of existing buildings, this session will share the best strategies, lessons learned and other considerations for achieving net-zero energy through retrofits.

An integrated net-zero review process must be in place, inclusive of iterative, integrated design facilitation, energy modelling, mechanical/electrical/renewables engineering, building science and commissioning to ensure all components of the design function together to deliver a net-zero retrofit that achieves high-performance energy and comfort goals.

Learning Objectives

  1. Understand the strategies for how existing building retrofits can achieve net zero/carbon neutrality.
  2. Understand the many challenges of net zero carbon or carbon neutrality.
  3. Understand how life-cycle costing can influence the financial drivers for achieving net-zero.
  4. Understand the risks that new technology and the complex system interactions poses for the goal of achieving net zero/carbon neutral retrofit.
