ABSTRACT
Water features, in urban areas, have a good effect on the micro-climate of surrounding with its cooling effect from the evaporative process. Thus, evaporative cooling maybe is one of the most efficient ways of passive cooling for building and urban spaces.
This paper describes the result of field measurement on the micro-climate around a water-wall at One-North Park, Singapore. Continuous measurements were conducted at eight points near this water-wall and one reference point outside the area for two month. Two typical days between 11th March 2008 and 23rd June 2008 represent clear sunny day and rainy day was chosen to get more understanding on the performance of evaporative cooling from the Water-wall at One-North, Park.
The cooling benefits from the Water-wall are shown not only from the cooler air temperature near the Water-wall but also to the lower air temperature in the nearby environment. The presence of water-wall at One-North Park obviously improves the thermal environment in hot sunny day by cooling the air. But the cooling effect is limited to its surrounding. The field measurement found that on 10am and 1pm, when the Water-wall is operated, the temperature drop was relative to the distance from the water-wall. The nearer to the water-wall, the cooler the ambient air temperature will be. The air temperature near the Water-wall were found 1.7-1.8K cooler than the reference point. These result shows that the temperature drop is induced by evaporation of water from the Water-wall. However, the apparent relative humidity profiles reveal that the water-wall tends to moisten the air through transfer of moisture from the evaporation process, which may influence the human outdoor thermal comfort in some extent.
Keywords: influence, water wall, air temperature, hot humid climate, Singapore.
