The Role of Building Ventilation on Building Decarbonization


Decarbonization of buildings leads to a significant reduction of CO2 emissions, which is essential in order to meet climate goals. However, this is a complex undertaking, especially when decarbonization is an emergent topic for the construction sector and households. Building ventilation is connected with many factors related to building decarbonization. Considering building ventilation requirements is essential when improving the energy efficiency of buildings (for example when improving the airtightness of existing buildings). Appliance electrification aspects of building decarbonization may also provide opportunities for better IAQ for the occupants and consequently decreasing the possibility of health issues. Furthermore, designing and proposing better building ventilation strategies can help us to meet climate goals. This session aims to bring people with expertise in building ventilation and IAQ, who are working on assessing building ventilation and IAQ strategies for building decarbonization. The goal is to generate a dialogue that addresses the relationship between building ventilation and climate change and promote awareness of the need to integrate ventilation and building decarbonization research.


This session provides targeted guidance and general background information to help to understand how building ventilation and IAQ is currently impacting in this energy transition, and how we should address our future research.

  1. Identifying the potential approaches, we can use to reduce CO2 emissions related to building ventilation and IAQ.
  2. Outlining current gaps and/or barriers for building ventilation strategies to meet climate goals and develop suggestions on how to address those gaps and/or barriers.
  3. Understanding why these strategies are necessary for meeting the climate goals and how we can improve them.
  4. Developing a preliminary document about the role of building ventilation in building decarbonization.


The topics of the sessions proposed in this program are selected based on general priorities in building decarbonization, such as: HVAC Systems; Health; etc.,
