An eco-friendly building material is one that increases the efficiency of energy used and reduces impact on human well-being and the environment. There are many different materials that can be used that are eco-friendly; from foundation, to insulation, to interior and exterior wall finishes, flooring, and countertop materials.
Source of Material
a. Renewable source
Rapidly renewable sources e.g. wood from certified forests
b. Reuse of Waste
Salvaged products –e.g. old plumbing, door frames
Recycled contents – agriculture/ industrial waste e.g. Bagasse Board
Embodied Energy
Scalar total of energy input required to produce the product including transporting them to the building site
Aluminium and steel has the most embodied energy because to the high energy required to produce them. Compared to timber that requires very less energy for production.
Reduce Pollution
Air Pollution– Use of materials with low VOC emissions e.g. Cement Paints
Water Pollution – Materials that prevent leaching.
Land Pollution– Materials that reuse waste that would otherwise have resulted in landfill. e.g. Flyash Bricks.
