Abstract

Buildings have a significant and continuously increasing impact on the environment. The powerconsumption for comfortable housing is ever increasing, which is adding additional burden to the powercrisis of the world. The main objective of this project is to reduce the heat transfer through the buildingroof by providing thermal insulation, thereby reducing the heat load on the building. Moreover, if thebuilding is to be air-conditioned then effective thermal insulation will reduce the power consumptiondrastically and saves lot of energy consumption. New innovative type of insulation is proposed in this workto reduce the heat transfer through roof structure by using seashells and coconut shells. The coconut shellsand seashells layer along with normal tiles will provide very good thermal insulation and it will maintainlow roof bottom surface temperature when compared with the normal conventional concrete roof withoutinsulation. Two identical experimental rooms were constructed on the top of the college mechanicalengineering department block and were instrumented with thermocouple and RTD along with data loggerfor obtaining continuous experimental results. The amount of heat reduction provided by the insulated roofstructure was calculated using the analytical method. Then the cooling load requirement for airconditioningand the corresponding energy cost per year was calculated for the new CAD lab of themechanical engineering department. The result showed the huge energy savings potential for thisinnovative thermal insulation technique. The electricity savings obtained is around 39.7%. when comparedwith the conventional concrete roof. This innovative technique for providing thermal insulation to thebuilding is more affordable and comfortable for living.

Summary

Introduction

Buildings have long been recognized as one of the most important man-made built structures imposing significant impact on both local and global environments. Buildings have an enormous and continuously increasing impact on the environment, using about 40% of natural resources extracted in industrialized countries, www.rspsciencehub.com consuming nearly 70% of electricity and 12% of portable water. Buildings consume a considerable proportion of raw materials globally and produce a significant amount of wastes during their construction and demolition process. Buildings accounted for more than 2040% energy consumption in developed countries. They are responsible for a large amount of harmful emissions, accounting for 30%of greenhouse gases due to their operation and an additional 18% caused indirectly by material exploitation and transportation. Efforts generally focused on single issues such as energy efficiency and conservation of natural resources in the course of striving for environmental excellence
