An Analysis on Low Cost and Energy Efficient Materials for Sustainable Housing
Introduction:
Sustainability can be defined as meeting the requirements of the present without compromising the requirements of future generations. Sustainable housing has the prospective to provide superior quality housing at a value that is reasonable both in long and short term. Thus, sustainable housing targets environmental, economic, and social sustainability from design to the execution phase and also result in reasonable and environmentally less damage housing. Bamboo is considered as one of the new rising materials which have extraordinary financial potential. Bamboo has been customarily utilized in India, Latin America, Philippine, and China for a hundred so years. It has been used as auxiliary individuals in short-length footbridge, low-ascent houses, long-range rooftop, and development stages.
Additionally, it is likewise abused in erection, design, destruction, and common works. The proportion of rigidity to the thickness of bamboo is multiple times higher than that of steel. The utilization of nearby materials in the various segments of working can help for low salary bunches. It was seen that with the utilization of innovation and reuse of waste material as a building material, the expense of development could be limited to a degree. The reuse of waste material like rice husk, fly debris, and so forth as a building material and the filler chunk can be utilized as an option in contrast to ordinary piece the expense of development can be decreased. The utilization of locally accessible or created constructing materials for housing can lessen the structures sway on the earth. It emphasis around five gatherings of building materials, for example, bamboo, compressed earth blocks, and interlocking blocks of reused materials, which are the promising structure materials for low cost sustainable housing development. It introduces a test for the improvement of maintainable structure materials.
Alternate Green Building Materials for Sustainable Housing Construction:
Some of the green alternatives for the building material that can have a lower impact on the environment at a low cost and helps in achieving sustainable housing are identified.
A. Bamboo:
Bamboo can be used as a reinforcement as an alternative to steel. It has been extensively used as a conservative building material and is attaining additional focus due to its potential for eco-friendly value in green construction. Bamboo provides more oxygen and absorbs more carbon dioxide, which is very superlative in combating global climate change. 
B. Palm Tree:
Palm trees are used as a building material for rafters, house walls, and roofing. It can be used as a column in construction. The palm tree is the strongest of tree species, and it can persevere for several years. It is hard, durable, and heavy and is greatly valued for construction.
C. Clay Bags:
Clay helps the bags mold firmly around the barbed wire, enhancing the tensile strength of the walls. Sand, gravel, and stone dust can sustain during flood conditions better but may need extraordinary bracing during construction.
Conclusion:
Porotherm brick and Compressed Stabilized Earth Blocks wall houses are affordable low-cost dwellings. The use of these blocks does not need plastering and painting. It will not cause any harm to human health and the environment. The cost of construction gets reduced. Materials used for eco-friendly construction are Mangalore tiles, Terra cotta tiles, Athangudi tiles, Porotherm bricks, Compressed stabilized earth blocks, bamboo, wooden rafters, and thatch. The cost of these materials is compared and analyzed to identify the low-cost materials for the construction of low cost and energy-efficient buildings. Filler slab was used to reduce the cost of installation. This type of construction is sustainable and helps in decreasing CO2 emissions. Apart from these materials, few green building materials are identified as an alternative to existing conventional materials, and their benefits and drawbacks are studied.
