Analysis of Load Demand and Economic Assessment Based on Weather Forecasting in Green Buildings


This1 study is concerned with the efficient integra-tion of the power management system from a microgrid with the power generation by using renewable resources and the green buildings concept. The software BIM was em-ployed in order to study the effects of climate and other external factors on energy consumptions and related costs. Two sites, highly different with respect to the climate condi-tions and cost of electric power (Bagdad from Iraq and Craiova from Romania) were addressed in order to evaluate the volume of CO2 emissions and respectively the effective-ness of power generation by using solar and wind energies. Two identical weather forecast buildings from the same sites were also studied. The results of studies over the monthly power consumptions structures for one year were discussed. The conclusions of an analysis concerned with the perform-ances (power consumption and costs) for 3 scenarios (with BIM, without BIM and respectively “high performance”) were presented as well. A study on the cost efficiency of photovoltaic cells arrays in different contexts was made, addressing the same geographic locations. General aspects of the influence of environment conditions (solar irradiance and temperature) over the performances of the studied PV array were approached for this aim. The seasonal Pay Back indices were evaluated for both locations, concluding that for any of them the use of the solar energy represents a cost effective solution for a “green” power supply. images
