Environmental Management Influence for Shade Trees on the temperature Reduction of yhe building.
Keywords:Architecture, Environment, Landscape, Plants
Thailand is located in a humid tropical climate and near the equator. Thus the average air temperature is high throughout the year. Environmental factors factors such as the sun, wind and humidity affects residential buildings especially, heat from the sun is a main factor, which leads a problems of heat inside the buildings (Prawewan Amornpong, 2001). Therefore, Installling air conditioning inside the buildings is the solution for this problem. However, from the study on the properties of plants it was found that plants are effective in blocking the sun's rays as well as effectively maintaining the air temperature in the area (Soontorn Boonyathikarn, 1999). So, planting trees to prevent the sunlight, as shade to reduce sun heat in the buildings should be an approach, which could be adopted to decrease the use of air conditioning and also energy consumption in buildings (Trungjai Buranasompob, 2000). This research aims (1) to study and create design guidelines on landscape models which conforms to the environment of sunlight and wind in the central region of Thailand and (2) to propose the guidelines on architectural landscape designs and plantsâ€™ setting around the buildings in 8 directions; North (N), Northeast (NE), East (E), Southeast (SE), South (S), Southwe st (SW), West (W) and Northwest (NW). The results found that the landscape model included the setting on plants as shade at all sides of the building envelope during 08.00-17.00 PM of the day throughout the year. These can reduce the air temperature of the building envelope as well as the average temperature inside the buildings, this showed a decrease in temperature by as much as 3.95°C or 13.478% compared with the average exterior air temperature of the buildings throughout the year.
