[Deep Dive 2] Natural ventilation for passive cooling – comfort today and in the future.

Throughout Canada many buildings are built in locations where the climate allows for using outside air for cooling at least some of the time. Passive cooling can be used to achieve comfort conditions for a significant number of buildings. If successfully implemented, there are multiple benefits to this strategy. The obvious benefit stems from the energy savings resulting from elimination of cooling air and mechanically moving it through the building with fans. Beyond this there is also the potential for improved comfort and the multitude of wellness and health benefits from a connection to the outdoors. In a work environment this might even lead to improved productivity.
However, there is ample anecdotal evidence on the fact that even in the most suitable environments, passively cooled buildings have failed. For success, buildings need to be designed to be suitable to be operated without mechanical cooling, and when appropriate, measures need to be taken to assure comfort. We will discuss the role of solar radiation, shading, occupant numbers, internal loads, thermal mass, stack effect, wind, solar chimneys and more, as well as when it might be advisable to provide some mechanical systems.

 In this session we will discuss how to design for comfort using natural ventilation for cooling, and where the limitations are. We will discuss this in both the conventional context of historic weather data and typical construction, as well as the context of 1) highly insulated, airtight buildings and 2) a changing climate, and both combined. This session will go into some technical detail on design process, design tools, climate analysis, airflow and thermal comfort analysis.
