In recent years, an increasing numbers of Bengalureans have started making efforts to minimize both environmental impact and financial outlay by outfitting their homes with sustainable technology.
The term sustainable homes is thrown about quite a bit these days, but there’s more to it than just segregating your waste and calling it a day. True sustainability is made up of many facets, from building materials to the use of renewable energy sources to design that strives for efficiency and harmony with the surrounding environment.
A green structure is an environmentally sustainable building, designed, constructed and operated to minimise the total environmental impacts. The carbon footprint of a home can be minimised through practices like reduced energy consumption, water conservation, and waste recycling.

A man who strongly believes in “Reduce, Reuse, Recycle and Rethink” principle, he has made his house literally from trash that he collected from demolished houses and second-hand markets.

When Rajesh Shah, a water conservation expert, and Vallari Shah, a passionate community gardener, moved back with family to India, they wanted to ensure that they lived a life as close to nature as possible. The result is a home in Laughing Waters, Whitefield, that they retrofitted for sustainability, one that today is intensely smart about water use and recycling, gets 90% of its vegetables from its own backyard, uses the power of the sun and has extended the philosophy to a thriving community garden project right inside their layout.
- The household gets 90% of their kitchen need from their own terrace garden.
- Harvested rainwater is filtered through a sand bed before being stored in underground storage tanks.
- Except for a few, all electronic devices run on solar power.

5. Sanjay and Pratibha Singh’s House
When artist Pratibha Singh and her husband, fellow-artist Sanjay Singh, moved into their home in Singapura, about 13 km from Bangalore, it was to get away from the city. Their idea of simple living took the shape of an environmental friendly home that is comfortable in every season. Enter the compound and you are greeted by a virtual green cave – a Pongamia tree-covered driveway. The house itself is built using stabilised mud bricks (a mix of cement, mud and quarry-dust) that, along with the similar flooring, ensures the house is cool in summer and warm in winter.
- With plenty of green around the house, and sunlight streaming in through the 8 foot-tall windows and skylights, the house has just one rarely-used fan.
- The waste water from the kitchen is recycled using a natural filter – a system of gravel, sand and other sediments that doesn’t use electricity – and then used to water the garden.
- The rain water harvesting facility also waters the garden for five months a year
- An organic garden is nurtured by vermicompost made from their wet waste.

A businessman by profession, Muthiah believes in consuming only what can either be generated or preserved.

- Grey water from washing machine and kitchen is filtered through a sand bed before being used in the garden.
Bengaluru-based architect, Chitra Vishwanath, has been a pioneer in green living for over 25 years and has used her experience, to design ecological spaces that conserve and use natural resources judiciously. Her firm, BIOME Environmental Solutions Private Limited, has created over 700 mud homes in India and Nigeria and many eco-friendly homes, schools and resorts. She is also an expert on rainwater harvesting.
Vishwanath believes that the time is right for people to adopt eco-friendly lifestyles, through sustainable architecture and not wait for the future. “Our resources are getting scarce. The more we trash our environment today, the bleaker our future will be. I believe in Mahatma Gandhi’s philosophy – The future depends on what you today,” she maintains.
Also, if your apartment complex or villa is eco-friendly, here is a chance to get it recognized. All you need to do is to get registered for My Place of Pride contest, an initiative of Rotary Palmville, in association with Bangalore Political Action Committee (B.PAC), to recognize eco-friendly communities in the city, encourage sharing of best practices and motivate people to adopt sustainable ones by ranking them. So far, 65 communities have registered; the process is open till February 2017.
