Sustainable development
This research chair aims to develop sustainable strategies for the construction and ventilation of dairy barns. The goal is to improve the resilience of the production sector and animal welfare, while ensuring efficiency and profitability.


Project Summary

Climate change poses new challenges for dairy farms: more frequent heat waves, freeze-thaw cycles, and ventilation systems that may be ill-suited to these conditions. These conditions increase the risk of reduced production, reproductive disorders, and diseases such as mastitis in dairy cows.

This research chair is working to develop practical environmental management solutions to improve cow comfort and health while optimizing farm profitability. The team evaluates the costs and benefits of different configurations (natural or mechanical ventilation), simulates the impacts of heat stress using digital tools and data from pilot farms, and proposes new design solutions. This work aims to provide producers with effective and economically viable strategies to prepare dairy farms for the climate of the future.


Expected Results

  • Standard designs for resilient barns with optimized ventilation
  • Predictive models of heat stress adapted to the Quebec context
  • Environmental and physiological thresholds to guide interventions
  • Strategies to improve ventilation management
  • Reduction in economic losses related to heat stress (estimated between $4.75 and $7.07/hL)

Main Achievements

  • Training of three master’s students and two doctoral students;
  • Hiring of a postdoctoral researcher in agro-environmental engineering
  • Plans to publish several scientific articles and educational content for producers and advisors.
