About This Course

Deep energy retrofits provide a coordinated, whole-building approach to significantly reducing energy consumption, greenhouse gas emissions, operating costs, maintenance issues, and occupant comfort concerns. Unlike standard retrofits that replace individual systems, deep energy retrofits address the interactions between the building envelope, HVAC systems, lighting, controls, plug loads, process loads, and building operations. Depending on the building type and existing baseline, these projects may achieve energy reductions of approximately 50% or more.

This course provides a practical introduction to planning and implementing deep energy retrofits in existing buildings. Participants will learn how to establish project objectives and performance targets, align improvements with capital renewal cycles, assess existing building performance, evaluate retrofit measures, and develop coordinated implementation pathways. The course also covers energy auditing, energy modelling, financial and risk analysis, detailed design, construction, commissioning, performance verification, electrification, available financial incentives, and strategies for overcoming common retrofit barriers.

Key Topics Discussed:

  • Definition, objectives, and benefits of deep energy retrofits
  • Differences between standard retrofits and coordinated whole-building retrofits
  • Identifying when a deep energy retrofit is appropriate
  • Establishing project objectives, performance targets, and long-term end states
  • Aligning retrofit measures with equipment replacement and capital renewal cycles
  • Developing phased retrofit pathways and sequencing improvements
  • Securing project funding and stakeholder support
  • Energy auditing and existing-building performance assessment
  • Energy modelling, calibration, and evaluation of retrofit scenarios
  • Energy, greenhouse gas, financial, feasibility, and risk analysis
  • Selection and bundling of energy conservation measures
  • Building-envelope, HVAC, lighting, controls, pumping, and domestic hot-water improvements
  • HVAC and domestic hot-water electrification
  • Heat recovery, peak-load reduction, and renewable-energy integration
  • Detailed design, construction planning, and implementation
  • Commissioning, operator training, and performance verification
  • Provincial and federal retrofit incentives and financing opportunities
  • Common deep energy retrofit barriers and strategies for overcoming them
