Additional Information  

ASHRAE TC 4.4 is sponsoring the following seminar:

 

Seminar 51: Emerging Building Envelope Materials: High-Performance, Low-Embodied Carbon Materials for Decarbonization


 – 

Location: Marriott Marquis Chicago, 2nd Floor, Water Tower A

Summary:
With the goal of achieving net-zero greenhouse gas emissions economy-wide by 2050, the building sector’s interest towards high-performance and low-embodied carbon materials development and deployment has spiked. The seminar aims to explore the most recent research and advancements in sustainable building materials development, with a specific focus on their thermal performance, durability, carbon footprint and overall environmental sustainability.

Chair:
Emishaw Iffa

Seminar 54: The Final Frontier: Developing Cost-Effective Retrofit Strategies for Residential Wall Assemblies


 – 

 Location: Marriott Marquis Chicago, 2nd Floor, Water Tower B

Summary:
Enclosure retrofits targeting envelope losses can save significant energy, reduce greenhouse gas emissions, and improve thermal comfort. The Oak Ridge National Laboratory, Pacific Northwest National Laboratory, and the University of Minnesota have been conducting a three-year study of residential retrofit wall systems. This study includes comprehensive literature review, the involvement of an expert advisory group made up of thermal enclosure experts, small-scale experimental in-situ testing of the wall assemblies, and energy and hygrothermal simulation of wall assemblies to produce a techno-economic study of residential wall systems for deep energy retrofits. This seminar summarizes the findings of this research project.

Chair:
Andre Desjarlais, Program Manager

William B. Rose made ASHRAE Fellow

Congratulations to William B. Rose, Research Architect at the Universality of Illinois at Urbana-Champaign on being made an ASHRAE Fellow. The Fellow Grade of membership recognizes exceptional contributions which distinguish the member. Fellow ASHRAE is a membership grade that recognizes distinction in the arts and sciences of environmental technology and is earned through achievement as a researcher, designer, educator or engineering executive. Bill is a long time member and contributor to ASHRAE TC 4.4 especially as Handbook Chair and chapter reviser. Congratulations Bill.
