The General Impact of

Materials Used in Buildings

What features of thebuilding affected by the

material selection?

Environmental Effects

With the beginning of environmental

sensitivity movement, green building conceptwas born. The concept of green or sustainablebuilding began with the environmentalpollution and the energy crisis (especiallyfossil fuel and oil crisis) fear in the 1970's. The

sustainable building movement anddevelopment based on the need for moreenergy efficiency and environmentallysensitive constructions.

Durability

With the correct choice of materials, buildings

can be constructed of adequate strength.

The basic construction material of buildings,cement, should be chosen carefully.

Besides the cement, auxiliary materials, such

as steels and filling materials, are also

important in construction. Depending on thetype of steel used, resistance to pressure

varies.

Economic Aspect Construction projects can suffer from financial

problems. Underbids ask for too little moneyto complete the project.

Cash flow problems exist when the presentamount of funding can not cover the currentcosts for labour and materials.

When the portions of a project arecompleted, while the logistical requirements

of having the right trades and materials Mistakes and major economical damages

can be prevented.

In Conclusion

Buildings should be contructed by thinking

two main areas; architectural design andmaterial selection, that contains economy,environment, ergonomy and durability . Withchoosing proper materials, buildings can bemore sensitive to environment, economic,sustainable and durable. Besides, ergonomy,

environmental sensitivity and cost-effect ofbuilding are developed with goodarchitectural design.
