Ventilation Strategies for High-Performance Multi-Unit Residential Buildings
From ZEBx’s Net-Zero Energy-Ready Playbook Series
High-performance multi-unit residential buildings (MURB) are becoming the norm in British Columbia. This shift in the building industry is the result of the increasing energy-related requirements mandated by municipal governments, as well as the need to satisfy the growing demand for high quality, sustainable developments. Many buildings are now designed to achieve Step 3 or 4 of the BC Energy Step Code (“Step Code”) or the Passive House standard, greatly improving the energy performance, comfort and quality of our residential building stock. These high-performance MURBs are being built by forward-thinking developers, municipalities, housing providers, and educational institutions who are paving a path for the rest of the industry to follow.
Achieving higher levels of energy performance means rethinking the way many aspects of MURBs are designed and built, including ventilation systems. A number of innovative and energy-efficient ventilation solutions are now available to help support the achievement of net-zero energy-ready and other higher performance targets.
This playbook provides an overview of the ventilation strategies used in net-zero energy-ready buildings (designed to meet Step 4 of the Step Code or the Passive House standard) and offers some guidance on making the right choice of ventilation system for the building
