Decarb Lunch: Decarbonizing Rooftop Units on Commercial Buildings

About this event 

This session will cover best practices for, and common barriers to, decarbonizing HVAC systems in existing commercial buildings, with a focus on Rootftop Units.  

In this ZEBx Decarb Lunch, we’ll share learnings from the City of Vancouver’s recent On-Site Barriers to Commercial Building Equipment Electrification Study, highlighting both the obstacles and practical solutions for decarbonizing HVAC systems. We’ll also hear about fuel-switching in action with a peek inside Vancity Credit Union’s pilot HVAC retrofit.  

CACEA's Integrated Design Process Facilitation Training - Hybrid (Calgary & Zoom)

The Integrated Design Process (IDP) is a highly collaborative approach to achieving sustainable (low energy, low carbon) practices and outcomes for both new construction and existing homes. It ensures delivery of affordable, durable, healthy homes for Canadians. 

CACEA is offering an interactive training program designed to provide comprehensive information about the IDP. The program places a strong emphasis on facilitation skills, equipping participants with the tools and techniques needed to lead and effectively guide this crucial process.

Residential Duct Air Flow Measurement: Assessing the impact of air flow on ASHP sizing

Duct capacity is often a limiting factor in sizing retrofit heat pumps, and contractors often size heat pumps based on the existing air conditioner, resulting in under-sized equipment. A simple 15-minute test can provide definitive air flow capacity of a duct system, contributing to a proper sized heat pump and avoiding poor system performance—such as noise problems due to restrictive ductwork. Energy Advisors (EA) can easily add this procedure to the scope of an Energy Evaluation.
