Reduction of heat gain through residential building with local plants for energy efficiency
Abstract:
This study was conducted to record changes of temperature in the measuring
boxes under the shade of three kinds of trees namely bamboos, mangoes and padauk.
They were compared with canvas shade. Interior temperatures of the measuring boxes
were studied to find the differences of temperature reduction inside the measuring
boxes. The experiment was carried out in an open area and measuring boxes were used
to represent the building condition to observe the internal temperature changes. The
data gathering was accomplished in September and October 2004 by means of data
logger collecting temperature data twenty four hours a day at intervals of every five
minutes.
One way statistical analysis was conducted and found that the internal
temperature of the boxes was influenced by the shade of the above-mentioned three
types of trees and the canvas caused the reduction of the internal temperature indicated
the significant differences at the confidential level of 0.05. The average temperatures
of the internal temperature of the measuring boxes which were influenced by bamboo,
mango and padauk trees were 35.5°C, 35.7°C and 36.9°C respectively. Meanwhile, the
temperature of measuring boxes with the canvas shade was highest at 38.4 °C, and the
average internal temperature of the control box was 37.2 °C.
The comparison of the differences between the control measuring box internal
temperature, the three trees influenced measuring box internal temperature and the
canvas indicated that the measuring box internal temperature which were influenced
by bamboo, mango and padauk trees were 1.6 °C, 1.5 °C and 0.2 °C lower than the
temperature of the control measuring box respectively. The canvas-shade influenced
measuring box internal temperature was 1.2 °C higher than the control measuring box.
It was concluded that different trees reduced temperature differently. Bamboos
and mangoes affected significantly and did not indicate statistical differences among
these two types of trees showed the statistical significant differential when compared
with padauk.
