Using CFD to Evaluate Natural Ventilation through a 3D Parametric Modeling Approach

Abstract: Predicting building air change rates is a challenge for designers seeking to deal with natural ventilation, a more and more popular passive strategy. Among the methods available for this task, computational fluid dynamics (CFD) appears the most compelling, in ascending use. However, CFD simulations require a range of settings and skills that inhibit its wide application. With the primary goal of providing a pragmatic CFD application to promote wind-driven ventilation assessments at the design phase, this paper… Show more

“…The urban built intensity determines the ventilation efficiency of the ventilation path [ 35 , 36 ]. As a morphological characteristic of the built environment, the urban built intensity has an obvious correlation with ventilation potential [ 37 , 38 ]. The characteristics have significance for urban planning.…”

“…In order to be efficient, the approach must deliver the airflow required to meet the indoor air quality criteria and external air thermal comfort parameters. However, natural ventilation is very variable, due to the climate force of wind (wind effect) and temperature (stack effect), which is an essential element for evaluating natural ventilation rates [46]. Envelope design is an important factor in deciding the energy usage in service of a building, and choices on its components often play a critical role in the energy costs needed for cooling as well as the necessary passive cooling [33].…”

“…Moreover, the complete settings of the E+ model, including the occupancy schedule and the .idf file, are available in the Data in Brief article [93]. Based on a one-week monitoring campaign (19-25 August 2014), an E+ numerical model was created, calibrated, and used to perform annual energy and natural ventilation assessments in [91,92], which also provide a detailed description of the measurement equipment, experimental protocol, construction, and the climatic data recorded on-site and used at the simulation. Moreover, the complete settings of the E+ model, including the occupancy schedule and the .idf file, are available in the Data in Brief article [93].…”
