Guiding Design Teams by Hygrothermal, Energy, and Thermal Comfort Analysis while Managing Uncertainty

By Morrison Hershfield|Dec 13, 2016 1:17:25 PM

Ideally moisture analysis of buildings is based on statistical analysis where the probability of failure, loads and design parameters are stochastic variables, similar to limit state design for structural engineering.  However, many industry professionals and standards, such as ASHRAE Standard 160 acknowledge that sufficient information is rarely available to make a full statistical analysis practical. 

Canadian Window Wall: Design challenges and opportunities

By Morrison Hershfield|Dec 1, 2016 1:00:00 PM

One of the defining characteristics of new high-rise residential apartment building design in Canada today is the thermally broken, open-back aluminum frame ‘window wall’ building envelope system. Until recently, Canadian building codes and Canadian and North American fenestration standards have not recognized window wall as a distinct cladding system.
