A study on surface temperature of different materials

Abstract

Excessive buildings took over green vegetation, which aggravated the greenhouse effect. If we use vegetation as roofs and exterior walls of buildings, the areas of plants will not reduce, and even the temperature around the building will decrease. Therefore, we planned to detect the surface temperature of different materials to provide evidence for ideal materials. We detected surface temperature of different materials with an infrared temperature gun (DELIXI, DM-5002). Detected materials included turf, suffruticosa plant, and soil under them, tile or concrete, wood, water with different depths of 1cm, 5cm, 10cm. We detected different materials under different weather conditions. The surface temperature of turf was significantly decreased compared with tile or concrete, wood (p<0.05). There was no significant difference between wood and tile/concrete temperature. Compared with tile/concrete or wood, the surface temperatures of water, turf, suffruticosa plant, and soil under plant significantly decreased (p<0.05). There was no significant difference of temperature between water with different depths. There was no significant difference in temperature between turf, suffruticosa plant, and the soil under them, too. The surface temperatures of turf, suffruticosa plant, and water were significantly lower than those of tile/concrete and wood we used as raw materials of buildings. Plants can be recommended as new materials covering roofs and exterior walls to decrease temperature around buildings in summer.
