Performance-Based Approach Simulation to Compare IAQ and Energy Performance of Two Types of Ventilation Systems Inside Individual Houses and Multifamily Buildings

Key Points

• Indoor air quality (IAQ) improvements are linked to specific ventilation system designs, enhancing overall energy performance.
• The study identifies significant differences in performance metrics between two ventilation system types over simulated scenarios.
• Simulation modeling was employed to assess energy use and IAQ across residential settings, offering a detailed comparison.
• Findings emphasize the need for optimized ventilation solutions to balance energy efficiency with air quality, particularly in multifamily buildings.
