Abstract

INTRODUCTION

Having a house that comes from your own hard work and professional dedication is the best gift a person can have. But what if the place you expect to lie on when you are tired is inconvenient? This is why the researchers conducted this study because they want to build a roofing structure using plastic bottles, mud, bamboo, and white-coated roof that will lessen the heat inside the house during summertime.

METHODS

The roofing of the model house was constructed using polyethylene bottles filled with mud. The giant bamboo was the ceiling on which the bottles were placed. Comparison of the room temperature was determined by preparing a traditional type of ceiling material that served as the control. Results were recorded in 5 consecutive days taking into consideration normal weather. It presents different data as a result of several testing used to produce a cooling system of a house. It also presents differences of the temperature outside and inside between the standard and modified bungalow house model. A quantitative experimental design was used in this study. T-test for 2 independent samples was used to arrive at the conclusion.

RESULTS

The research found that Polyethylene Plastic, Mud, Giant Bamboo, and White-coated roof as a multilayer composite thermal insulator truly decreases the temperature inside the house. Temperature decreased by 2 degrees Celsius when it is inside the standard bungalow house model while it decreased by 4.7 degree Celsius inside the modified bungalow house model. T-test shows that the computed t-value 11.7, compared to the value with the t-tab 2.447, it is formulated that the null hypothesis is rejected and the alternative hypothesis is accepted which means that the roofing materials used were effective in decreasing the temperature inside the house.

DISCUSSIONS

Results show that the multilayer composite thermal insulatoris effective as an alternative cooling system. Results also show that the modified bungalow house made up of bamboo as a ceiling platform is more effective than that of the standard hardiflex used in a typical bungalow house. Polyethylene bricks are also more effective as an insulator in comparison to the insulator sheet, while a white-coated roof is more effective than the typical roof.
