Pattern Language from Passive House: 4-Part Online Course

January 12 @ 12:30 pm - 3:30 pm

Overview

How to Design and Build High-Performance Apartment Buildings at the Lowest Possible Cost 

“A Pattern Language from Passive House” is an interactive course that teaches cost-effective planning and design of affordable, low-emission, mid-rise, multi-unit, wood-framed housing.


This four-part online course presents design problems common to multi-unit buildings, followed by solutions that have worked in previous high-performance projects. These solutions are organized into “patterns” using a format adapted from A Pattern Language by Christopher Alexander (et al).


The patterns presented in this course are drawn from the hundreds of affordable multi-unit buildings constructed to the Passive House standard worldwide, because this is the largest cohort of affordable, low-emission, mid-rise, multi-unit housing. While these solutions are taken from Passive House buildings, they are applicable for residential building design to meet Step 4 of the BC Energy Step Code, as well as multi-unit buildings aiming for similar low-TEDI or not-zero energy standards. Likewise, while this course focuses on affordable housing, the patterns apply equally to market- and luxury-housing projects.


What to Expect

This course has been designed to be a highly interactive online experience. Participation in group discussions is expected.
