Theme C: Education and Market TransformationA modernizing and urbanizing China with limited energy sources has to promotesocial awareness regarding the necessity of embracing sustainable concepts appliedto new developments. This is an issue that deserves the close attention ofgovernment, industry and, indeed, a challenge for architects and buildingengineers.In line with this panorama, this paper describes an initiative between the WSA andthe Tianjin University to apply sustainable issues in new campus buildings, as thenew compound to be constructed for the Shandong Art College, Jinan.In order to reach this purpose, an investigation was conducted to point out thepotential of using natural ventilation during summer season to improve pedestrianscomfort and safety levels in external areas. Along with this, the use of a naturalventilated ground cooling/heating system to control the internal environmenttemperature proved to be efficient, minimizing cooling/heating needs for thisproject and, therefore, acting directly on the energy consumption reduction as well.2. THE NATURAL VENTILATION ANALYSISComputational Fluid Dynamics (CFD) simulations were carried out aiming toidentify wind flow patterns amongst built area and site topography, highlightingthe wind resources potential and how to build comfortable external environment,predicting the occurrence of breezeways, wind acceleration and still air areas. Thepurpose is related to avoid wind during winter, making the best use of this naturalresource in summer. Ventilation can bring thermal comfort improvement aspsychological effect through wind velocity, since it increases makes people tofeel cooler [2].Two spots of special attention on this analysis were the ones designated by“courtyard 01 and 05”, localized in front of and in the rear of the main building,due to the fact that they consist of outdoor meeting point areas, intended toconcentrate people during summer time (see Fig. 1).622
