Environmental-comfort building layout principle for a coastal industrial park

The Taiwan government has been following the green energy policy for decades to cope with drastic climate change due to global warming and tremendous urbanization. Forming a database to assist Taiwanese policy makers in using the concept of energy efficiency and environmental comfort in urban planning and architectural design is required. This paper depicts how the field and CFD studies for an industrial region located in rural and monsoon wind prevailed district of the mid-western coast Taiwan were conducted, and how the data are used to construct building layout principles for regions having similar climate conditions. For the purpose of analyzing field data and forming database, measured atmospheric and microclimate parameters, such as the physiological equivalent temperature (PET), were first converted into empirical relations. Then, these empirical equations were used as the input and validating values for the CFD simulation model based on the FLUNENT software. Five field-observed wind profiles were used as the inlet conditions, and the computed results of the five-street canyon aspect ratio, and of four-building arrangements, are analyzed to construct the building layout principles. The study results show that the principles for a monsoon wind prevailed region should better be the following: (1) the street canyon aspect ratio is 0.1 and not over 0.3; (2) the building layout is a single open arrangement, avoiding a staggered setting.
