Considerations to Arrive at a Successful Natural Ventilation Concept

Speaker: Dr. Andrea Frisque, P.Eng, LEED AP, Senior Building Performance Engineer, Stantec

Location: Policy Labs, CIRS building, 2260 West Mall

Date and Time:  1-2 PM, Thursday, February 4th


Using natural ventilation rather than solely mechanical ventilation can potentially have many benefits, to both the human experience of a space and its energy performance. At the same time there are risks associated with natural ventilation designs which need careful considerations to avoid failure. For standard spaces which have been built many times before there are a solid knowledge base and reasonably reliable rules of thumb on how to design and use such spaces successfully. For unconventional, innovative designs it is likely necessary to use engineering tools and skills as well as a well-integrated design process to arrive at a satisfactory solution. This presentation offers an initial overview of natural ventilation design and typical mistakes to avoid, such as for example excessive heating needs during the winter time, overheating in the summer, poor air quality, acoustic problems and more. Analyses and tools that can be used to test design concepts and derive solutions will be introduced.



Dr. Andrea Frisque is a Senior Building Performance Engineer at Stantec. She provides technical direction and leadership in low-energy design for buildings and communities. She publishes technical papers in international journals, presents at national and international conferences, and has been invited to give many talks and lectures.

Dr. Frisque has over 15 years of experience related to analyses and computer simulations for sustainable design. She uses her extensive knowledge in heat and mass transfer, thermodynamics and fluid dynamics to provide cost-effective sustainable design and unique solutions, helping project teams achieve their sustainability goals. Dr. Frisque’s area of technical expertise includes: Passive systems and natural ventilation performance analysis using whole building simulations and CFD, Occupant thermal comfort assessments, Whole building energy simulations, Building energy consumption reduction and feasibility of energy efficiency and sustainability measures, Renewable energy systems and usage of on-site energy sources (i.e. solar, wind, river water cooling), and Daylighting design and analysis
