Reference number : GC-2017-Q2-04295, amendment number : , agreement type : G, recipient legal name : Santana Quintero, Mario (Carleton University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Conservation of our existing building stock is becoming a more significant portion of architecture and_x000D_
engineering practice in Canada. Heritage masonry buildings whether stone or brick, have proven to have been_x000D_
durable in Canadian climates surviving over 100 years or more. A weak point of these walls is that they are_x000D_
considered to have poor energy performance compared to modern code standards. When considering thermal_x000D_
comfort and the desire to reduce energy consumption, there is often consideration to installing thermal_x000D_
insulation along interior face of walls during a retrofit/rehabilitation scenario. This is known to have a negative_x000D_
effect on the durability of the wall leaving exposed to colder and wetter interstitial conditions and prone to_x000D_
freeze-thaw and other moisture-related damages [1]. The questions that follow are; how far can a masonry wall_x000D_
be pushed before the risk of moisture damage becomes unacceptable? And how do you quantify or determine_x000D_
this risk?_x000D_
The industry problem is to develop a workflow which effectively combines hygrothermal and energy modelling_x000D_
software to analyze the hygrothermal performance of wall assemblies; while at the same time including_x000D_
consideration of the simultaneous effects of mechanical systems and interior conditions as a system. This work_x000D_
will help with the understanding of the current baseline condition of the walls; and help guide and justify their_x000D_
design proposals._x000D_
The underlying challenge is to develop a hybrid workflow for hygrothermal and energy modelling of heritage_x000D_
structures which effectively utilizes the capabilities of software programs such as WUFI and EnergyPlus. For_x000D_
heritage structures, there are specific gaps in understanding and procedural workflow which need to be_x000D_
addressed. This new workflow seeks to build off of previously developed workflows for the analysis of_x000D_
hygrothermal performance of walls in isolation, and add to it consideration of system level changes such as_x000D_
mechanical systems which will affect interior conditions., program purpose french : Conservation of our existing building stock is becoming a more significant portion of architecture and_x000D_
