Facing the growing problem of the electric power consumption in Egyptian residential building using building performance simulation program

Egypt has been experiencing recurrent power cuts especially at the summer, with the problem being made worse by the extra demands placed on the electrical grid by the advent of the holy month of Ramadan. Electricity shortages are now a problem in Cairo, Alexandria, Sohag, Qena, Luxor, Aswan, and Nubia, as well as in the Nile Delta governorates of Beheira and Qalioubiya. The aim of this study is to develop a model for the Egyptian residential building using Building Performance Simulation Program and make sensitivity analysis on some variables effecting the electric power consumption in order to help faceting the growing problem in Egypt. The model was created using the IES-VE 2012 (Integrated Environmental Solution ). The simulation model was verified against the survey data for the Egyptian apartment and same model simulated using energy Plus simulation tool. The results of the program describing different situations for energy using profile for the air conditions, lighting and equipments in respect to building layout and construction climate and pattern of use. This model can be used in the future to help in reducing the electric power consumption in the residential building

Calibration of numerical simulations modelling of nonresidential building in hot humid clmate region

In Egypt, energy use in buildings has grown in the last 20 years mainly due to the increases in population, number of households, number of offices, as well as increase in service demand, such as more air conditioners and computers. The aim of this study is to create a thermal model for Egyptian office building to represent actual building energy consumption trying the best fit for user behaviors and actual weather data. The simulation model was created using IES VE 2014 and calibrated against measured data for an Egyptian office. The calibration process, intermediate and final results are presented and illustrated for a range of output parameters including internal temperatures, CO2, lighting, equipment, and cooling energy use for different weather periods. This calibrated model can then be used together with uncertainty analysis to evaluate future building upgrade scenarios in order to help improve the energy performance for Egyptian office buildings
