And this phenomenon did impact the natural environment in the capacity of losing designated functions for temperature modulation. Thus, problems like “heat islands effect” would come natural with increasing high temperature problem on daily basis. Predictably this would also influence earth’s temperature. Since campus is the long term location for education purpose, therefore to understand heat islands effect from varieties of outdoor pavements towards school campus environment, would prod the university campuses to have the environmental buildings transformed into energy-saving, environmental protection conscientious and green campus, so as to effectively lessen the phenomenon of heat islands effect in the end. This research primarily explored the atmospheric change and impacting factors for open space in the campus environment and selected the types of outdoor open space pavements within campus foundation to proceed to qualitative analysis. And the findings of analyses will be applied to sustainable campus building foundation planning. Henceforth, this research adopted onsite measurement method and selected Providence University located at outskirt of Taichung City as research subject. The research also targeted all types of outdoor pavements such as： Lawn pavement, PU pavement, porous pavement and nonporous pavement, and proceeded to 25 times all-weather measurements 24 hours a day, measuring the changes and variances for hovering air temperature, humidity and various environmental factors for different types of pavements. Then these measurements and datum were statistically compiled so as to facilitate the understanding for heat changes and influencing factors for campus outdoor pavements. The research findings pointed out that, since different types of outdoor pavements within campus were directly under influence of sun radiation, and temperature differences were straightforwardly reflecting on different types of pavements. Temperatures on grass or lawn pavements were found to be the lowest, followed with porous pavement in contrast with the highest temperature found with nonporous pavement type. These were acquired from the actual measurements of different spaces with similar grass or lawn pavements. And the localized micro-weather changes were ostensibly affected by surrounding environments. Long term temperature change predictions for each type of pavement simultaneously conducted were further processed for relevancy analysis through the actual measurement information and datum, with the collected samplings from Wuci Weather Station. Then regression formulae for predicting the temperature for campus pavement were established as result. Then this set of formulae were applied to predict the annual temperatures for different pavement types at Providence University and the prediction results were further correlated with temperatures measured from Weather Stations to establish the underpinning relevancy. Hence, the prediction models for campus temperature variation momentum were also established as result.
