The rising population, growing demand for housing, and the widespread impact of climate change have led to an evolving construction philosophy that utilises sustainable building materials such as recycled materials, solar panels, energy-efficient water fixtures, etc. These alternative building materials reduce emissions, are environment-friendly, and save money in the long run.

Sustainable Construction Materials Used in the Housing Industry

Recycled Steel

Recycling steel is far more economical and consumes less energy to produce than virgin steel. 40% of steel is recycled making it one of the most recycled materials in the world. Due to its durability, it is used in structural columns and beams and is hence considered one of the more sustainable architectural materials.

Green Concrete

Concrete or cement is one of the most common construction materials but has a high carbon footprint. To maintain the sustainability of cement and make homes more environment-friendly, developers are exploring a number of green concrete options. These include slag or fly ash and low-carbon cement alternatives such as geopolymer or hempcrete which have lower carbon emissions.

Insulation Material

The insulation material in walls and windows can affect your home’s temperature. Recycled cellulose insulation, natural wool or cotton insulation, or insulation made from recycled denim or cork are some of the sustainable wall materials used to insulate your home. They are eco-friendly and more energy efficient.

Sustainable Wood

Wood is an integral part of the process of constructing a home. As a conscientious homeowner, you can make sure that the wood used in your home is sourced sustainably from responsibly managed forests. Bamboo and recycled or reclaimed wood are some other sustainable alternatives to wood with a lower carbon footprint.

Green Roofs

Rooftop greenhouses and gardens are a popular option to reduce a building’s carbon footprint. They provide thermal insulation and promote biodiversity. Green roofs can also be designed using sustainable roof materials such as terracotta or clay tiles which last longer and absorb less solar energy, thus maintaining a cool temperature in the home.

Low VOC Paints

Paints contain Volatile Organic Compounds (VOCs) which contain toxic chemicals that contribute to indoor air pollution. Low or zero-VOC paints are an environment-friendly alternative that has lower emissions and promotes better indoor air quality. They also provide a better painting experience and last longer.

To conclude, the Indian real estate sector is becoming increasingly environmentally conscious. Incorporating innovative new technologies, materials, and methods helps build green or net zero energy homes. 

 

Frequently asked questions

1. What are some sustainable facade materials used in building green homes?

Ans. Cork, recycled brick and plastic, hempcrete, natural stones, and polyurethane are some such materials .

2. How can we reduce a home’s carbon footprint?

Ans. Besides constructing a house with sustainable materials, one can also design the interiors sustainably. Indoor plants, low VOC paints, furniture made of cane or recycled wood, etc. help reduce your home’s carbon footprint.
