Many local governments have applied cooling system like street shading, cool roofs, and cooling fog system into public space and city buildings in response to increasing frequency and intensity of heat waves. In particular, shading facilities are now receiving increasing attention from urban policy-makers as it can be applied to various urban spaces like urban street, park, and public buildings. However, as it can be easily installed in various places, many shadings have installed in unsuitable places where temperature reduction effect is not huge or significant. The difficulty for urban policy makers is that the effect of shading hugely depends on their materials and surrounding environment, and it is also difficult to predict the accurate effect of each shading before installation. By applying sample shading panel and IoT sensor into temperature measuring equipment, this study tries to develop a simulation equipment which can measure the effect of urban shading before it gets installed. The effects of simulation equipment was reviewed through the process of comparing it with the temperature changes of the actual shading system applied in public childcare center. Although there was slight difference in measured temperature, simulation equipment was confirmed to be effective to measure the temperature changes of the urban shading.
