“…In the past decades, an increasing amount of guidelines and papers have stipulated the importance of validation of numerical models in general, and of Computational Fluid Dynamics (CFD) in particular to ensure the trustworthiness of the simulation results (e.g. Schatzmann et al, 1997;Casey and Wintergerste, 2000;Dalgliesh and Surry, 2003;Franke et al, 2004Franke et al, , 2007Tominaga et al, 2008;Schatzmann and Leitl, 2011;Blocken et al, 2011;Blocken and Gualtieri, 2012). The validation of numerical models that are used to analyze natural ventilation is not always straightforward.…”

“…In addition, many physical problems in wind engineering and building physics, such as wind-driven rain on buildings and heat and moisture transfer in porous building components require on-site measurements because these phenomena cannot (fully) be reproduced at reduced scale (e.g. Dalgliesh and Surry, 2003;Blocken and Carmeliet, 2005). The same holds for natural ventilation due to the combined effect of wind and buoyancy, as explained below.…”

“…All these issues cause damage claims and large repair and replacement costs to the owner (CWCT, 1994). Therefore, understanding the WDR effect in the hygrothermal performance of the building envelope is important (Blocken & Carmeliet, 2004;Dalgliesh & Surry, 2003).…”

When performing hygrothermal analysis for building envelopes, climate data is required as boundary conditions. This study investigates the effect of the microclimatic conditions using Toronto Pearson Airport and downtown hourly data. The results showed that the average water content of the wood frame building façade were similar throughout the study period. The high moisture content peaks reduced to average within days. The arithmetic averaged hourly weather data may also affect the analysis’ results. 5-minute weather data is collected from the Ryerson weather network. The hourly data is constructed from the 5-minute data by arithmetic averaging. The simulation results from both dataset followed closely to each other throughout the study period. The averaging of hourly data removed some details form the raw meteorological data. However, it does not affect the overall trend of the climate condition and the impact to the hygrothermal analysis of building components is very limited.

“…Secondly, the pressure is usually treated as a constant flow of indoor air. Further, the common flow of indoor air flowing is substantially vulgar, with flow often at 10∼20 m/s or less, and, therefore, the indoor air can be treated as incompressible fluid [13]. Finally, the indoor air viscosity cannot be neglected; we must use the theory to study the dynamics of a viscous fluid.…”

Wind angles affect building’s natural ventilation and also energy consumption of the building. In winter, the wind direction in the outdoor environment will affect heat loss of the building, while in summer the change of wind direction and speed in the outdoor environment will affect the building’s ventilation and indoor air circulation. So, making a good deal with the issue of the angle between local buildings and the dominant wind direction can effectively solve the winter and summer ventilation problems. Thereby, it can enhance the comfort of residential person, improve indoor air quality, solve heat gain and heat loss problems in winter and summer in the severely cold and cold regions, and reduce building energy consumption. The simulation software CFD and energy simulation software are used in the paper. South direction of the building is the prototype of the simulation. The angle between the direction of the building and the outdoor environment wind is changed sequentially. Energy consumption under different wind angle conditions is compared with each other. Combined with natural ventilation under various wind angles, the paper gives the best recommended solution of building direction in Shenyang.
