A review on cost optimization techniques in energy efficient building (March 2018)

The energy performance of a building is determined on the basis of the calculated or actual annual energy that is consumed in order to meet the different needs associated with its typical use. it includes the heating energy needs, cooling energy needs , energy needed to avoid overheating to maintain the envisaged temperature conditions of the building and domestic hot water needs. Investments made for energy efficiency of a building can be compared with the capital cost investments, which is necessary on the input side of the energy system to produce a similar amount of peak capacity or annual energy production. Usually, the capital costs of efficiency are higher than comparable investments in increased supply. There are additional operating costs of efficiency compared to substantial operating costs for inward energy options. In addition, energy efficiency investments generally have much shorter lead times than energy supply investments, a particularly important consideration in countries where the demand for energy services is growing rapidly. This paper deals with literature review of cost optimization techniques for energy efficient buildings. Here a number of sixteen journals were reviewed on this topic. Reviews of these papers were done to identify different energy efficient techniques that could be used in a building from planning phase to operational phase. These papers also express about 10-20% optimization of energy and cost Using the data used in reviewed papers, a methodology for studying the various techniques could be identified.
