A literature survey on Energy Efficiency Enhancement in buildings considering harmonics in nonlinear load

In this manuscript, the author has reviewed the technique used to improve the energy efficiency in buildings. Poor power factor caused by nonlinear loads in a building result several power quality problems from the point of view of energy consumption of buildings. Average energy consumption of an academic building is taken into consideration for estimation of the cost of energy consumption in the building throughout the year. The current and voltage RMS as well as THD is taken into account of various non-linear loads used in buildings for different analysis. The current and voltage harmonics of different order is also studied. Application of a capacitor and a resistance in shunt (as shunt passive filter) resulted a considerable amount of improvement in total harmonic distortion of current of nonlinear load present in an academic building. Widespread use of this kind of filters will ensure lesser amount of transmission loss. However the application of this filter may vary for different kind of loads.
