Toronto ASHRAE chapter is please to have consultants night as the theme of our last meeting of the "ASHRAE year". We are extending our invitation to design engineers and plan to have the evening's conversation focused on this audience.



Active Systems in Passive Design

Passive House projects have gained significant momentum in North America. The first projects were more focused on single family dwellings. More recently Passive House has expanded into large commercial projects in particular, multifamily residential buildings. This presentation will focus on design considerations around providing ventilation design for Passive House multifamily residential projects. The presentation will discuss the pros and cons of centralized versus decentralized ventilation systems. Issues such as locating duct work, fire damper issues, impact on multiple wall penetrations, joining exhaust air from multiple apartments, energy performance of centralized vs. decentralized systems etc.

An unexpected consequence of air tight Passive House high density multifamily projects is humidity control in winter. A detailed discussion of what is happening, how to recognize the potential issue and how to mitigate it will be discussed. Finally, on applications where mechanical cooling is being considered, a discussion on how to tie the ventilation system into the cooling system will be reviewed. In particular, best practices for connection ventilation systems to VRF.
