Good Essays

INTRODUCTION

We always say that we must protect the earth that’s why low emission cars, flourecent lamps, recycled papers, paper bag for groceries, etc. are now practised all around the world including the Philippines, but
If we are really concerned for our environment, why don’t we start with our home instead, literally speaking we could use materials that is efficient at the same time is cheaper and would emmit lower damage in our environment.
Limestone and Gravel have an important role in building structures they are the most commonly used aggregates for concrete and concrete is the most used building materials since the Romans. The problem with using minerals is the proccess of getting it, because it is a natural resources we have …show more content…

The east half of the basement is completely underground, while the west half is only partially underground with the top 1.8 m of the walls above grade. The buildings have an extremely high amount of thermal mass with large south and east facing windows. The building shells are poured concrete construction with 20.3 cm exterior walls, 30.5 cm flat roofs, and 15.25 cm basement slab floors. The windows are all located on the south, southeast, and east facing walls and made of low-E glass. The windows have aluminum frames with a thermal break and clear double pane low-E glazing units.
The roof extends 1.50 m from the building to provide an overhang. The south building from the southeast direction on a clear December morning. The two buildings are very close together, so the south building partially shades the north building at low sun angles. High-R fiberglass insulation material was used in both buildings. The average overall building heat-loss coefficient UA value of the south building is approximately 613 Btu/ h• °F and the north building is approximately 694 Btu/ h• °F. The difference is mainly due to the larger glass area in the north building and, to a smaller extent, the higher thermal conductivity of the concrete in the north building. The description of the building is provided by the JOURNAL OF ARCHITECTURAL ENGINEERING © ASCE /
