Adapting and repurposing older buildings for new uses with advancing energy and environmental concerns is challenging and requires specific expertise. Bruner/Cott & Associates presents a methodology for the analysis of building envelope improvements in existing buildings focusing on two buildings in Eastern Massachusetts.
This methodology focuses on each building’s unique material characteristics and an approach that not only addresses the concerns of thermal resistance, condensation and freeze/thaw cycles, but also the architectural implications of energy conservation measures.
The team’s extensive experience rehabilitating historic buildings and as building science practitioners enables them to evaluate methods and make decisions related to the building envelope while providing the best architectural solutions.
This presentation will highlight the approach, the decision making process and the results of various completed and on-the- boards projects including Harvard Blackstone Building and the Dartmouth Class of 1953 Dining. The following topics in particular will be addressed: existing envelope construction and masonry characteristics, weather exposure, freeze/thaw events, saturation and density tests, building program and MEP changes that affect air pressure and RH factors, vapor and moisture permeance, compatibility with architectural enclosures, and recommended monitoring systems.
