Seminar | “Towards Smart Ventilation” in Mid-sized buildings
|Date||Monday May 23|
|Time||10:30 - 12:30|
This interactive session is a seminar/webinar chaired by Hilde Breesch, and co-chaired by Jelle Laverge, Ivan Verhaert, Douaa Al Assaad, Twan Van Hooff. It is an outcome of the collaborative work of the Flemish VLAIO Flux50 strategic basic research (SBO) project “Towards Smart Ventilation in mid-sized buildings” and the International Energy Agency (IEA) Energy in Buildings and Communities Programme (EBC)’s Annex 86 for energy efficient IAQ management strategies. The objective of this seminar is to have an interactive discussion between HVAC experts and building designers on the requirements of highly energy-efficient “Smart Ventilation” systems in mid-sized buildings. Such systems can continually adjust their operation to provide the desired indoor air quality (IAQ) while minimizing energy use, utility bills, thermal discomfort and noise. They should also be responsive to e.g., occupancy shifts, dynamic outdoor conditions, contaminants’ sources and can provide information about e.g., IAQ, energy use. For mid-sized buildings, where the system complexity exceeds the typical ‘all-in-one-box’ solutions that are available for single-family dwellings, the design of ventilation systems is very conservative and inefficient. Moreover, no method exists today to select the most optimal system and room layout in a specific building based on a coherent set of indicators. This interactive session will aim to address the knowledge gap by presenting a performance assessment framework consisting of a general economic indicator. The indicator can be integrated as an objective function in the design optimization of air distribution networks. The indicator is tailored for different room types, and IEQ parameters (acoustics, resilience, occupant behavior, sleep). The use of a global economic indicator is an improvement on the current ventilation design methods, which are driven by minimum requirements for IAQ, energy consumption and/or investment costs. The key takeaway from this seminar is to acknowledge the importance of establishing such an assessment framework for ventilation systems in mid-sized buildings. This seminar will allow participants to interact, through polls and room discussions on the research objectives, methods as well as the possible outcomes and valorization paths.
