Factory assembly: the new way to build PH Assemblies
The YWCA Project is the first mid-rise precast Passive House building in Canada. The concrete precast panels offer an affordable solution that in one envelope achieves air tightness, weather tightness and continuous insulation. This eliminates the need for multiple trades, reducing the time on site and allows for higher quality finish by manufacturing most of the major building components off site. Factory assembly buildings can be the future of PH envelopes. However, in order to succeed, all the members of the team need to be involved and work together from the beginning.
Through the implementation of BIM for all aspects of project work, from Schematic Design to Passive House Energy modeling, efficiencies to the design process can be achieved.
Working alongside an iterative design development process, allows designers to understand and evaluate the impact design changes can have, as they relate to PHPP Verification. Through the creation of Passive House BIM Content used to quantify and report data for PHPP inputs, significant efficiencies can be made in data collection and entry which is favorable for quick design decisions and energy analysis, and can be evaluated prior to full Architectural design revision and cost analysis.
Those who have designed and built to Passive House standard are well acquainted with the “devil in the details.” Passive House construction can be highly technical but there are ways in which passive house construction techniques can be simplified and adopted by the wider construction industry. This session will feature a moderated conversation amongst peers working in the GTA including a panelized builder, two product suppliers, a PH consultant, and two architects. Several scenarios will be presented and each of the panel members will walk participants through their approach to detailing each scenario from design through to construction.
