BHUBANESWAR: Green homes can reduce the energy consumption by 50 per cent. Mili Majumdar, Director, Sustainable Habitat Division, The Energy and Resources Institute (TERI) tells Shradha Goyal of MagicBricks.com Bureau, why India needs more home owners to think green.
In India, the concept of green is very important. The residential sector alone accounts for 24 per cent of the total electricity consumption. Green Homes have the ability to cut down the energy consumption by 50 per cent and water consumption by 60 per cent. Therefore, propagating the green concept can result in direct reduction of energy.
The country is facing an acute shortage of water, especially the mega cities which are grappling with this issue. Similarly, the rising energy consumption and prices pressurize the existing supply of electricity. On an average, per sq meter built-up space can save around 20 units of energy, annually. For instance, in a typical 1200 sq ft Green Home with Rs 5 per unit of electricity, one can save up to Rs 10,000 every year. Similarly, these homes have a potential to bring down the per capita water usage by 30-40 per cent.
Thus, with such saving potentials, green homes can easily be said to be affordable. In the long run, Green Homes turn out to be more affordable than normal homes. The initial cost to own these is just 1-4 per cent more than the normal homes. However, one can easily recover this extra expenditure within two years.
If you are committed to green, then it is quite possible to convert your existing property into a green home. Though it is not possible to change the orientation and envelope of an existing building, there is a lot one can do to make their homes energy efficient. Since, windows are the largest sources of heat gain and loss, the key component is to use these most efficiently. Energy efficient windows have a huge potential to save energy. Using reflective materials on roofs and walls, light colors in paints and curtains, allowing maximum day light, selection of household appliances rated by Bureau of Energy Efficiency, solar water heating system and installing Rain Water Harvesting system are a few things one can do to easily make their homes energy efficient.
