Abstract | Micro-scale heat island phenomenon refers to the temperature rise of a micro-scale built area, e.g. a street, a square and/or even an urban district above the ambient air over the area. This paper presents a simple temporal 3D air and surface temperature model for an ideal courtyard, which is a semi-enclosed open space surrounded by buildings. The prediction model includes the transient heat conduction in the ground and through the buildings walls, the heat removal/addition by courtyard ventilation, and detailed solar radiation and thermal radiation exchanges between surfaces. The air temperature in the courtyard and its surface temperature distribution can be analyzed minute by minute within a day or during a longer period if the temporal ambient air temperature and weather data are given. We simulated a courtyard located in Beijing. The solar radiation and the urban structures are found to be the most important factors in determining the courtyard thermal environment during both summer and winter. The thermal properties of the building walls also play a significant role. The results are revealing in developing effective methods for mitigating or managing micro heat island, and control thermal environment in a courtyard. © 2012 Elsevier Ltd. |
