Application of the building materials to enhance the building life cycle cost
Building materials, material properties, building defects, building life cycle, green building,
In present, wide range of raw materials are consumed by the building construction industry. With significant growth taking place in the building industry, the burden being placed on limited resources. Therefore selecting the proper building materials are playing vital role of the building industry to enhance the efficiency of the selected materials during its life cycle stagers.
For a successful construction project, the design, material selection, and construction must all be satisfactory. The project may be envisioned as a 3-link chain, governed by the weakest link. A sound design with quality materials may become a failure if construction is poor. And also poor material selection may badly affect to health and safety issues, inefficient use of energy, maintenance issues, durability and the life span of the building,
There is a useful distinction to be made between materials that are furnished in the final state, e.g. steel and wood, and those that are essentially manufactured on the job site, e.g. concrete, masonry, and asphalt. For materials manufactured on site, the engineer may bear a much greater responsibility for ensuring that tests are performed and interpreted correctly. It is often necessary to accept or reject materials on the basis of limited test information.
Green building materials are composed of renewable, rather than nonrenewable resources. Green materials are environmentally responsible because impacts are considered over the life of the product.

LEED, or Leadership in Energy and Environmental Design, is changing the way we think about how buildings and communities are planned, constructed, maintained and operated.
Case Study : The up-market shopping complex in the old Race Course building at Reid Avenue, which was renovated preserving its historical value and colonial architecture in 2014 by using the manpower of the Sri Lanka Army (SLA).
Old building was renovated when utilizing modern building materials, reusing the existing building materials. It is consisting with spacious corridors, stairways, celebrative building façade and providing wide ventilation spaces. The modern complex accommodated for supermarkets, restaurants and office spaces. The Colombo Racecourse Ground was developed as the Sri Lanka’s first international rugby stadium and is now equipped with the latest facilities for rugby, including a state-of-the art gymnasium, changing rooms, media rooms and a jogging track encircling the grounds. The pavilions provide seating facilities for over 2,000 spectators. Also designed adequate car parking spaces for the visitors and modified lanes for people to have strolls.
