HVAC Optimization of Energy Management: Case Study of an Office Building
Keywords:energy management, Energy conservation, Pakistan, Energy optimization
Pakistan has been in a state of severe energy crisis since 2006-2007. Not much progress has been done since 2008 to cater the required energy needs. This is a major hindrance in the economy, leading to prolonged hours of load shedding. According to Energy Experts Group constituted by Economic Advisory Council in 2009 in Pakistan, it is estimated that the energy demand for Pakistan by the end of 2030 will increase by 64%. Steps therefore need be taken not only to install new power plants but also to implement policies which are energy optimized. According to survey, more than 50 % of energy in Pakistan is used in buildings. From amongst the buildings, a major portion of energy is utilized in office buildings. Special incentives should be given to companies by the government whose buildings are energy optimized.Â Surveys and studies have shown that office buildings that have the HVAC (heating, ventilation and air conditioning) system optimized by energy conservation methods; have shown considerable amount of saving of electricity cost. A case study has been carried of an office building where the current electricity utilization is analyzed and optimization techniques are suggested. Further, calculations are done to show that if suggested methods are implemented for system optimization, energy saving of about 33.25% can be achieved.Â Pakistan is currently facing crippling effects by the hands of energy crisis. If similar energy saving can be done by other office buildings on a larger scale considerable contribution can be made for the country to emerge from one of the most dreadful energy crisis ever.
