An Investigation on Optimization of Energy ConsumptionPortfolio in Urban Regions (Case Study: Shiraz Residential Sector)

Researches indicate that considerable share of energy consumption is allocated to housing construction sector. On the other hand, the average consumption of energy in Iran residential buildings is 2.58 times more than the world standard energy consumption. In fact, the residential sector, by allotting the portion more than 41.9 % of energy resources, is the major energy consumer sector in Iran. It should be mentioned that not only the potential energy savings in residential sector is more than the other sectors, but also the possibility of reduction of energy consumption in this sector is easier and with less investment than the other sectors. Therefore, the essentiality presentation an oriented energy pattern for the Iranian house is very tangible. The importance of the presentation oriented energy pattern has specially been enhanced after facing to the multi-prices and multi-periods energy applications. The aim of present research refers to modeling oriented energy pattern for Iranian house by presenting a mathematical model for optimization of multi-periods and multi-prices energies by considering consumption portfolio. The mathematical model is then solved by two methods such as BLP and HDC, separately. For evaluating the degree of efficiency of the proposed algorithm, Shiraz city residential sector has been chosen as the statistical population, and the energy consumption data (electricity and gas) of 270 Iranian houses were deployed. The obtained results from two methods of BLP and HDC indicate the optimal management of limited resources of energy, the amount of recourses usage in each period, and also a decrease in energy consumption costs about 26.1% and 30.5% (by HDC and BLP, respectively) compared to the real data.
