Clayton Heights Community Centre

This new 76,000 SF multi-use facility is pursuing Passive House certification, which would make it the first community center to achieve Passive House in North America. Morrison Hershfield assisted with thermal analysis of building envelope, envelope reviews for meeting Passive House performance requirements and airtightness and water Penetration Testing.

Humber College Building NX

The green overhaul of the 30-year old NX building on Humber College’s North Campus has achieved Zero Carbon Design certification from the Canada Green Building Council, becoming the first retrofit to secure the designation. Renovations on the structure included a building envelope retrofit and energy-efficient upgrades to the heating and cooling systems to strategically address the institution’s energy and water consumption with the goal of reducing energy, water and greenhouse gas (GHG) emissions. It is designed to meet Passive House certification. (Etobicoke, ON)

 

Hygrothermal Modeling to Meet Performance

Minimizing moisture-related risks in enclosure assemblies plays an important role in building durability and indoor air quality. Assessment of hygrothermal (combined thermal and moisture) performance is recommended for Passive House assemblies, and is sometimes required as part of the submission package for Passive House Pre-certification.

Passive House

Passive House

Architects, engineers and building owners face a new challenge in their projects: meeting the ever-increasing demands of building and energy codes.

Across North America, codes and regulations are moving toward net-zero energy for new construction. As a model for achieving ultra-low energy buildings, the Passive House Standard acts as the perfect “stepping stone” to provide a clear path to net-zero. Focusing on thermal comfort, air quality and durability, the Passive House approach optimizes the passive building systems to create sustainable, energy-efficient structures.

Our Passive House approach focuses on minimizing heat transfer by avoiding thermal bridging and increasing moisture control by preventing water intrusion and condensation. Our team’s expertise in Building Science, including the building envelope, thermal analysis, enclosure component modeling and energy modeling, makes Passive House a natural fit for Morrison Hershfield.

Our team includes Certified Passive House Consultants and Designers, with Passive House project experience across North America. Our industry-recognized research like the Building Envelope Thermal Bridging Guide and the Guide to Low Thermal Energy Demand for Large Buildings both support Passive House design and contain a collection of design solutions and details to help multi-unit residential buildings meet net-zero ready and Passive House standards.
