Abstract
Several studies investigated the impact of urban forests on city micro-climate. Evapotranspiration, alone or in combination with shading, can help reduce peak summer temperatures by 1-5°C. Tree-shade alters building cooling loads by preventing incident solar radiation on building facades. Tree-sun-building interactions influence the magnitude of this effect. The objective of this paper is to present a simplified method for making these interactions effective for dwellings in Amman, the capital of Jordan, representing a Mediterranean climate. We selected two types of trees, commonly used in residential plantation. The location of these trees around the studied building as observed in real practice. The method of analysis depended mainly on how a tree can reduce direct solar absorption by the building’s wall, when it casts shade upon a wall portion through day time. This is then subtracted from the overall cooling load; a total summation of the trees effect is then calculated. Using tree-shade as an external shading strategy showed that there is notable decrease in cooling loads; therefore, as a result there is reduction in electricity consumption. It is important for future studies to set up an energy conserving planting program criteria in Amman including tree selection and site recommendations.
