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. 

Holistic Approach to Achieving Low Energy High-Rise Residential Buildings

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


As codes and standards evolve towards low or net-zero energy buildings, the practicality of achieving these targets in high-rise concrete construction gets increasingly challenging. High-rise residential buildings are becoming more common as cities redevelop and add density.  Current design and construction practice for high-rise multi-unit residential buildings (MURBs) presents a number of constraints with regards to achieving high levels of energy performance. 

Visualizing the Pathway to Low Energy Buildings - The Real Impact of the Building Envelope

By Morrison Hershfield|Jan 1, 2016 1:00:00 AM

Building envelope thermal performance is greatly affected by thermal bridging, or localized areas of increased heat flow through walls and roofs. Mitigating the impact of thermal bridging is not only necessary to reduce energy consumption but is also an important consideration for minimizing the risk of condensation on cold surfaces and for maintaining occupant comfort.
