Assessment of Natural Ventilation in a Case Study Building using the Adaptive Thermal Comfort Model

Frederico Martins de Barros, Rodrigo Mora, Chris Flood

Abstract: The paper presents a natural ventilation assessment using field testing and whole building simulation model (WBSM) of a case study building located in Vancouver. The thermal comfort is evaluated using the adaptive thermal comfort (ASHRAE 55, 2013). The field testing includes the installation of an on-site weather station and sensors to monitor the indoor environment. The WBSM is used to analyze the impact of design features that compose the natural ventilation strategy in a sensitivity analysis. The design features analyzed are solar shading system, internal spaces connectivity, green roof, and a solar chimney. From the field testing, using the adaptive thermal comfort, it was found that for most spaces the natural ventilation was effectively delivering thermal comfort for the building occupants. The sensitivity analysis shows that for the case study building and Vancouver’s climate there is not just one design feature that is substantially more effective than the others.
