How about living in a house where your electric bill is reduced substantially thanks to optimum use of natural light clubbed with an efficient lighting system?

It will surely benefit your pocket, but more important, this can also help reduce your carbon footprint.

This is possible for anybody provided he looks at energy efficient ways, says 31-year-old SHM Adil, an energy analyst by profession.

Working on a simple idea of "saving by design approach", Adil claims the electrical gadgets have a direct impact on human behaviour.

What this student of TERI University pursuing his doctoral studies does is to calculate energy efficiency ratings for buildings.

The data pertaining to electronic devices vis-à-vis its energy efficiency ratings etc and the weather data for the area is fed to a computer, which applies it to a mathematical model of the building using a special software.

Based on this, Adil through his firm GEED — Global Evolutionary Energy Design ( -- conceptualises various energy efficiency measures (EEM) that are possible for the client and the architect of the building.

These measures have different impact on annual energy consumption and rated according to the potential for saving for the user.

Among other things, the "saving by design approach" helps you find out: What can be the impact of different wall and roof material on annual energy use?

What is the solar insolation (solar radiation received at the earth's surface) in open landscaped area?

What is the wind profile of the location and can it be harvested for ventilation?

What can be the electricity bill for a building installed with energy efficient measures/devices?

"This method would give us an edge in reducing carbon emissions," the M Tech (Energy and Environment Management) from Indian Institute of Technology Delhi asserts.

He gives credit to his mentor Professor N.K. Bansal, who inspired him to take up the cause.

So has there been any change in his habits?

He grins and adds, "Well, I do still use the air conditioner, but I don't abuse it."

Entries from outside the capital


Trina Talukdar, 22

An international climate champion, she had initiated a campaign — art for the environment — during the Copenhagen Summit. The aim of the project was to create awareness about the urgent need to protect the environment among the participants through cultural events, and consequentially, put pressure on decision makers to make policies that protect the environment from further damage.

Idea: Using arts to protect climate


Syed Zahed, 35

He has designed an innovative hybrid & efficient system, Simple Home Energy System (SHE), worth $125, that supports day-to-day energy needs for cooking, heating, lighting and other miscellaneous power needs. He is currently the Secretary, Integrated Community Welfare Association, Kandukur, and he has been associated with several NGO’s throughout his career.

Idea: Providing turnkey energy solutions.
