Learning Objectives

  • 1. The benefits of electrification: why policymakers and designers are

moving towards electrifying new and existing commercial buildings

  • 2. What technologies will be used to electrify commercial buildings?
  • 3. How right timing and integrated solutions can enable capital and energy

cost-effective electrification.

  • 4. How to choose the right electrification technology based on existing

building systems

slide-3
SLIDE 3

Session Description: Learn the process of electrification for new and existing commercial

  • buildings. Information about recent technologies, including HVAC, hot

water, and the whole systems approach, will be presented. Learn more about the various incentives and clean energy programs available.
