There are several chemicals including formaldehyde, benzene, ammonia, resins, chemicals in insulations, ply boards which are present in furnishings and building material. Thus it is advisable to use the non-toxic building materials for construction.
Use of toxic building materials can significantly impact the health of construction people and the occupants of the building. Energy-efficient materials must reduce the amount of generated energy.
Use of locally available building materials not only reduces the construction cost but also are suitable for the local environmental conditions.ĥ) Using Energy Efficient Building MaterialsĮnergy efficiently of a building material can be measured through various factors as its R value, shading coefficient, luminous efficiency or fuel efficiency. The use of local materials reduces the dependence on transportation whose contribution to the building material cost is high for long distance.
The natural materials impact more sustainability to structures as well as they are friendlier to environment. The natural materials such as stones, wood, lime, sand and bamboo can be used in ample wherever possible. It is therefore advantageous to use materials or composite materials prepared from the wastages. The greater a material's embodied energy it requires a greater usage of non-renewable sources. The total energy required to produce a material is called embodied energy.

These results in reduction of pollutants to environment.Ģ) Use of Recycled wastes as Low Cost Building Materials Efforts should be made to study and revise the technologies for producing good quality, efficient building materials and should improve the waste generation during manufacturing. Manufacturing of building materials should be environment friendly. The building phase mainly consists of construction, operation, maintenance and disposal last the stage where the material can be recycled or reused.ġ) Manufacturing of Low Cost Building Materials Pre-building stage mainly consists of manufacture which is subdivided in processing, packing and transport. These three stages indicate flow of building materials through different stages of a building. Each stage of building should be such that they help conserve energy. The life cycle of a building is pre-building, building and post-building stages. This also enhances the sustainable design principle. The first step to low cost building material selection is to select eco-friendly building materials. Selection of Low Cost Building Materials for Low Cost Housing Composites as Low Cost Building Materials.8) Recyclability and Reusability of Building Materials.7) Longevity, Durability and Maintenance of Building Materials.5) Using Energy Efficient Building Materials.3) Use of Natural Low Cost Building Materials.2) Use of Recycled wastes as Low Cost Building Materials.1) Manufacturing of Low Cost Building Materials.Selection of Low Cost Building Materials for Low Cost Housing.
