Going Tropical: Cooling & Ventilating in Zone 0A (Kimberly Llewellyn, 2026 Westford Symposium)

 

Talk title: "Going Tropical- Building, Cooling and Ventilating in Climate Zone 0A"

Kimberly Llewellyn is a humidity and HVAC forensics, training, and resiliency design consultant and co-owner of Blue Rabbit Consulting. She previously worked with Mitsubishi Electric's Performance Construction Team and contributes to Fine Homebuilding and Phius, focusing on high-performance HVAC design and building envelope forensics in extreme and humid climates.

Healthy Living in Tight, Compact Homes: A Holistic View (Ashley Murphree, 2026 Westford Symposium)

Ashley Murphree is a co-founder of Good Bones Design Build, a design-build firm in the Bay Area building high-performance, healthy homes. In this talk from the Westford Symposium, she draws on her own experience as a chronic complex illness patient to introduce the cell danger response, a framework for understanding how mitochondria, immune cells, and the building envelope all interact as layered membranes.

Fluorocarbon Technologies: Refrigerants & Efficiency (Mary Bogden, 2026 Westford Symposium)

Mary C. Bogden is a Research Fellow (Senior Principal Scientist) at Solstice Advanced Materials, formerly Honeywell, where she develops next-generation low-GWP refrigerants and foam blowing agents. In this talk from the Westford Symposium, she walks through the chemistry and regulatory landscape behind fluorocarbon refrigerants and insulation blowing agents, covering EPA and EU rules on fully fluorinated compounds, flammability classes and refrigerant charge limits, and why spray foam loses R-value over time.

Can We Learn From Our Past? (Sophie Mercier)

Sophie Mercier is a building envelope specialist and co-founder of Evoke Buildings, a Vancouver-based Building Science and Energy consulting firm. She is going to ponder: With our eyes on the prize of ultimate sustainability, carbon emission reduction, are we too often focusing on the tree rather than the forest? We always think we can do it better than our predecessors, but sometimes we forget what they did, why, and how they did it.

Embodied CO2e (Andy Shapiro and Jacob Racusin)

Andy Shapiro has a barefoot engineering degree from Brown University and is President for Life of Energy Balance, Inc. Jacob Racusin is an embodied carbon researcher with Builders for Climate Action and New Frameworks and is a killer sax player. They will dive into operational and embodied CO2e and their effects on the atmosphere over time for a pair of dormitory/apartment buildings in Vermont that were designed and constructed to be “net zero ready”. Design and material strategies, successes, failures, and lessons learned will be presented.
