Monika Woloszyn, enseignante-chercheuse au LOCIE présentera une conférence keynote lors de la conférence ASHRAE : The Sixth International Conference on Efficient Building Design, en format hybride (à Beyrouth + en ligne) le 7 novembre 2024.
sa présentation MOISTURE, MATERIALS, AND HVAC SYSTEMS SOME INSIGHT INTO HYGROTHERMAL INTERACTIONS AT DIFFERENT SCALES
portera sur:
Moisture in construction elements has a recognized effect on building performance, as it impacts not only moisturerelated damage but also thermal energy performance (thermal conductivity). Several construction materials are strongly hygroscopic, and old construction materials, such as earth and timber, are among them. It is also important to maintain indoor relative humidity at correct levels, to ensure hygrothermal comfort and indoor air quality (IAQ). For example, humidity-controlled ventilation systems are widely used in several European countries. With the tightening of energy performance directives all over the world, and the necessity of low carbon shift, there is a growing interest for detailed studies of moisture-related phenomena at different scales in the field of building performance. What is relevant at the material/wall scale? What is relevant for the interaction with the HVAC system and comfort? The talk will discuss related issues, show some examples, and try to address some questions.
