With increasing urbanization, people are constantly migrating to the cities. This is leading to congestion, in terms of space and resources. Thus, more and more houses are built and are planned to be constructed to accommodate the increasing population. The construction sites near the residential areas cause pollution of different kinds that affect the inhabitants. These pollutants can interfere with the natural composition of the air, water, and soil, by introducing toxic elements. This could lead to hazardous health issues for the construction workers.
To reduce the global warming effects and the increasing levels of pollutants from the construction of houses, dams, flyovers, and streets we need eco-friendly construction methods. Sustainable construction aims to highlight the use of recycled, eco-friendly products and renewable sources of energy for construction purposes.
Sustainable methods include the elements of construction such as designing structures, raw materials, construction technology, resource efficiency, technology, environmental sustainability, work conditions for the workers, architectural placement on the plan of the city, landscape viability, safety from natural disasters, functional use, and society’s functional fabric.
Here are some ways to go eco-friendly:
Use of eco-friendly raw materials:
- Use of Lime: Calcium carbonate also known as lime [protects from bacterial wars against the walls and is resistant to the ultraviolet light. It is a much greener option than cement and causes less pollution than the paints we generally use. It can be used in the form of lime mortar & putty.
- Natural Insulation: A well-insulated house saves a lot of energy as it keeps the house cooler in summer and warmer in winter. Natural alternatives for insulating materials like wool, cellulose and wood fibre are low maintenance materials with larger benefits. They can be recycled and reused as per requirements. They provide additional support by regulating humidity and reducing the issues of condensation.
- Biomass Roofing: The modern market for biomass roofing is expanding day by day, as the need for renewal construction increases. This includes thatch roofing and wood tiles.
- Biocement: Construction material like concrete can be replaced by biocement.
Green building techniques aim to use natural products that are non-toxic. This kind of construction also helps local businesses.
Construction Waste Management:
It is important to segregate the construction waste material. Arranging different bins after segregating the waste and crushing the leftover waste
Reusing Waste Material
Materials should not be disposed of if they can be reused after painting or fixing like doors and windows. Furthermore, these waste materials could be used for commercial purposes.
The potential solution to the pollution crisis by the construction in urban and rural areas can be dealt with by reinforcement of environmental and construction standards.
