Energy conservation can be achieved by trimming down the energy consumption of the edifices. Six storey edifice of Shoolini University at Bhajol, Solan, Himachal Pradesh (India) is taken as a case study in this work. Energy load of the edifice during winter months is 165.27 MWh, whereas during summer months is 110.99 MWh, and thus annual load is 276.26 MWh. The total energy load of the edifice has been met out by using conventional sources of energy. The emission of CO2 by using fossil fuels has been estimated and worked out 1.11 tonne per annum. Adoption of solar passive features (viz. insulation to north wall and the roof, increasing glazing at south wall, double glazing at north wall) and energy efficient technologies like light emitting diode in the building can reduce the energy consumption by 36.61% besides resulting reduction in CO2 emission by 36.94%. The fuel bill of the building will also be reduced by 36.67%. All the suggested energy efficient features require Rs 34.0 lac investments with a payback period of four years.
