Pakistan is in phase of increasing economic growth which is also giving people to raise their standard of living which is growing in building construction. This is further rising the demand of electricity which is a big challenge for Pakistan. The energy savings made at load sites are nowadays regarded as energy generation. Taking all this parameter into account, there is an urge for alternative way to minimize the energy consumption in order to overcome the electricity shortfall in Pakistan. A detailed analysis has been conducted to lower the annual energy requirements of the test site. The optimization strategy mainly involves (i) energy audit, (ii) retrofitting technique .An important finding is that the payback period of all technique is less than seven years. The results indicate that when 3 inch polystyrene insulation is internally employed along with the energy efficient appliances, an electricity saving up to 22% with a payback period of 4.96 years can be achieved.
