Proposer Additional Info
I have presented at conferences over the past fifteen years, with subjects from energy efficiency to IAQ and health in buildings.
Proposed Session Description
With an estimated average EUI, QSRs (Quick Serve Restaurants) are considered some of the most energy intensive buildings. And there are hundreds of thousands of them. They are also very challenging to retrofit with efficient HVAC systems. This session outlines how we are doing it, and includes multiple case studies from across the USA.
Diversity and Inclusiveness
These restaurants are in neighborhoods across the country, and many of the employees working in these spaces are working in less than ideal, and sometimes unhealthy spaces. This model improves IAQ and health while saving significant energy.
Learning Objectives
Attendees will be able to recognize significant opportunities for retrofitting a large class of buildings that can have a very large impact on energy use and the grid.
Attendees will know what the VHE HVAC model is, how it works, and how to implement projects of their own utilizing the model and specification.
Attendees will understand the Best Practices for accomplishing these VHE HVAC projects.
Attendees will know how to estimate savings and costing for these somewhat small but impactful projects.
Has this session been presented before?
No
Additional Comments
I have presented on the VHE HVAC model, but never for QSRs, and the case studies are new and have not been shared.
Target Audiences Level of Expertise
Level 2 - Some prior knowledge helpful.
Session Format
Presentation followed by facilitated discussion or breakout groups
Session Format Details
60 minutes with presentation and case studies, then 30 minutes of audience engagement, including working with spreadsheets to gain insight in to the load calculations and system sizing of the VHE HVAC model.
Recommended Length
90-minute session

Anything else you'd like to tell us about your session proposal?
This is a straightforward proposed presentation and working session. But it could have a outsized impact on a building class that has been completely ignored, and yet which has potential for more energy savings per square foot than any building type I have encountered in almost twenty years of working in this space.

Full Description
QSRs are consuming huge amounts of energy. They are also everywhere! Cutting an EUI from an average of about 420 down to the low 200s, with hundreds of thousands of these buildings operating every day, often 18 hours per day or more, would have an extremely large impact on cutting energy use. And providing a model that pays for it over a short period of time makes it compelling.
