BC lab focus on issues related to building and climate. Spatially, including small-scale climatic and human thermal comfort, indoor and outdoor micro-climate, and large-scale urban climate issues. Based on long-term weather data by simulation, out study extends to the issue of climate change and the built environment Adjustment Technology and Architecture Design. BC lab emphasizes interdisciplinary and multidisciplinary research ,we have long-term and close cooperation with the Meteorological Research Institute of University Freiburg in Germany.
Quantification of the effect of thermal indices and sky view factor on people’s attendances in a park. Outdoor shading affects the thermal environment and thermal comfort of humans, and hence, influences the usage of spaces. The purpose of this research is to establish a relationship between thermal environment and the number people attending the outdoor space, as well as to explore the outdoor space utilization intensity in different seasons with different shading levels. This research conducted onsite investigations on the micro-climate parameters of the thermal environment and the number of attendances in a park in central Taiwan. The results in cool seasons showed a positive correlation between air temperature, mean radiant temperature (Tmrt) and physiologically equivalent temperature (PET) of shaded areas and the number of attendances. In hot seasons, Tmrt and PET, which reflect solar radiation conditions, have negative correlation to the number of attendances. In other words, higher Tmrt/PET values indicate fewer people attending the park in summer. Meanwhile, there is a significant correlation between park utilization and solar radiation condition. This research, for the first time, proposes the use of regional sky view factors (SVFr), instead of traditional single-point sky view factor by fisheye photographs (SVFsp), as the indicator to measure shading level of different areas in parks. Analytical results demonstrate that the lower the SVFr, the higher the utilization intensity of the park. This research highlights the importance of shade design in parks in tropical or subtropical climate, which can serve as a reference of park design in the future. This figure won Landscape and Urban Planning Section 107, which is international number one Urban Studies in the field, published park thermal comfort research for the cover story.
