Free Webinar: Full and Partial Electrification Strategies for Commercial Building Retrofits, Construction and Central Plants
Event Description

Building electrification through the use of heat pumps is gaining traction as an effective means to reducing emissions from building operations. However, barriers remain to 100% adoption of this technology, especially in existing buildings where cost, space or other constraints exist, requiring creative approaches to maximize emission reductions per dollar spent. This webinar will demonstrate ways to create deep emission reductions through right-sizing heat pumps, better HVAC design, integration of thermal storage and hybrid solutions. The session will also cover how such approaches may extend the life of equipment.

In retrofits for example, replacing a boiler with a similarly sized heat pump may often be impractical and/or costly. This course will present new research that analyzed HVAC data from 200 commercial buildings revealing that standard design practices are greatly over estimating peak loads, and how this knowledge informed case studies that reduced emissions by as much as 70% through boiler retrofits, improved control strategies, and/or hybrid systems. Speakers will also present a method for quickly screening to identify candidate buildings for retrofit.

For new construction, this webinar will present a case study that integrated thermal storage to fully electrify a higher education building, downsizing the heat pump while meeting a stringent design-build budget. This approach also offers improved flexibility and building whole-life responsiveness to meet the changing demands and emission profiles of the future grid. Finally, the course will present case studies of central plant electrification projects in California that led to impressive emission reductions.

The objective of this course is that at the conclusion, participants will be able to:

- Describe the benefits from right-sizing heat pumps in commercial buildings
- Give examples of challenges or alternatives to full adoption of heat pumps in commercial buildings
- Show familiarity with a screening tool to identify candidate buildings for electrification
- Cite one or two case studies that made deep emission reductions using thermal storage or boiler retrofits
