1. Room Air Conditioners
01.Use ceiling or table fan as first line of defence against summer heat. Ceiling fans, for instance, cost about 30 paise an hour to operate – much less than air conditioners (Rs.10.00 per hour).
02.You can reduce air-conditioning energy use by as much as 40 percent by shading your home’s windows and walls. Plant trees and shrubs to keep the day’s hottest sun off your house.
03.One will use 3 to 5 percent less energy for each degree air conditioner is set above22°C (71.5°F), so set the thermostat of room air conditioner at 25°C (77°F) to provide the most comfort at the least cost.
