The Cost saving of using Limestone as a local material in Construction for lower height Buildings in Middle of Egypt

Abstract

The sustainability awareness has developed to include many countries that contribute to sustainable environmental residential buildings, as environmental buildings, looking toward an innovative idea, integrated design and unique formation, The research deals with the concepts of sustainability, their criteria, evaluation methods and their relationship to the local economy that to obtain the design of an existing sustainable environmental using local materials in each different environment at the lowest economic cost. Through the investigation study of natural construction materials in Egypt, it was found that natural limestone is one of the best environmentally friendly building material compared to other available building materials in terms of reducing thermal loads on the building, which leads to reducing energy consumption at the level of energy use and as local materials in construction, and achieved an economy building from survey study through the market of construction materials for housing , moreover using the limestone to improve the humanities skills and the opportunity of skilled workers . The research concluded with positive results for the use of limestone in the construction of sustainable buildings dealt with an analytical study using the design builder environment program to analyse the differences between internal and external temperatures, to achieve the best thermal comfort inside the rooms through an applied model with achievable sustainability factors of economics and humanities.
