Celebrated each year in India on 14th December as National Energy Conservation Day, the India Energy Conservation Act was implemented by Energy Efficiency Bureau (BEE), in 2001. It is a constitutional body which works under Government of India and helps in the development of policies and strategies to reduce use of energy.
With the primary objective to reduce energy reduce energy intensity in the Indian economy through adoption of result oriented approach. The Energy Conservation Act in India aims to prepare and implement schemes for efficient use of energy; designate or appoint certified energy manager in charge of activities for efficient use of energy and its conservation; get energy audit of the building conducted by an accredited energy auditor in this specified manner and intervals of time.
1. Site selection: Ensure ease of access to daily life needs like schools, hospitals, supermarkets and public transport. Reducing travel time and maximum use of public transport with reduced used of private vehicles reduces consumption of per capita fuel and wear and tear of automobiles.
2. Design of the building: Implementing a whole-building systems approach to new construction is the most efficient way to achieve an energy efficient building. The building is treated as a holistic entity with different parts where energy consumption is treated as a complete entity. Each part affects the performance of the entire system (the whole-building). The design of an energy efficient building should easily be able to adapt to newer technological upgrades without impacting the sole structure of the building. The architecture of an energy efficient building should be worthwhile and non-interrupting. A sustainable design aims to reduce wastage of indispensable resources like land, water, energy, and raw materials. Long term engineered value of facilities and infrastructure also reduces possibility of destruction of the ecosystem.
3. Landscaping and natural habitat: As the global consciousness about the preservation of the environment is rising, the importance of landscape architecture is also growing. With a growing ecological crisis looming; including severe droughts, top soil depletion, loss of biodiversity and watershed pollution, our approach to landscaping requires a shift from degenerative to regenerative design and installation. There is a growing market for outdoor recreational activities, water elements, featured walkways, shady landscaping for summers, cabanas, natural sitting areas.
4. Ventilation: Install localized exhaust fans above kitchen ranges and in bathrooms to create spot ventilation. Inhouse ventilation improves the effectiveness of natural and whole-house ventilation by removing indoor air pollution and moisture. In warmer countries like India, south facing windows are efficient to prevent excessive heat gain during the summer, preventing constant usage of air conditioners and coolers. With increasing pollution and adoption of air purifiers, natural ventilation & natural habitat needs to be promoted in a dynamic method.
5. Heating & cooling systems: Cooling, heating, and water heating account for the largest energy expenses in residential spaces. Energy saving water heaters use 10 to 50 percent less energy than standard models, saving energy and money on utility bills. Solar water heaters, low power consumption geysers, central home geysers are methods to avoid unnecessary power consumption. Reducing run time of air conditioners by replacing it with thicker curtains, to filter the sunlight, or usage of reflective films. Using more plants to keep the indoor environment green is another great option.
6. Energy efficient lighting: In incandescent lamps, 90 percent of the electricity is wasted as heat rather than light and also 3-5 times more power is consumed. Replacing old lighting systems and bulbs with high power saving lighting system. Energy saving lighting like fluorescent lamps, CFL lamps and LED lamps and incorporating correct lighting controls such as timer controls, temperature controls, ultrasonic sensors based controls may seem like an initial investment but go a long way in improving the power productivity.
7. Energy efficient appliances: Always go for industry approved appliances which are higher star rated, they use 15 percent less energy than non-qualified models. Refrigerators with top-mounted freezers use 10-25 percent less energy as compared to bottom mount, or side placed freezers. Use natural sun to dry out clothes as much as possible, instead of using the drying option in the washing machine.
8. Smart electronics and devices: Mostly utilizing energy efficient electronics, computers, and office equipment can save homeowners half the electricity caused by personal devices. Replace heavy desktop with sleeker, efficient power consumption laptops. Turn off the laptop instead of putting it on sleep mode, when not in use for over couple of hours. Unplug devices when not in use also restricts energy wastage as many electronics continue to draw a small amount of power even when switched off. These little draws on energy can occur on most appliances that use electricity: like DVD players, TVs, stereos, computers, battery chargers, and kitchen appliances.
