This study by investigating the common and available methods of implementation, as well as their inefficiencies will provide a new more efficient method. This new method, in fact, will first assess the required time of implementation in each of the units of the organization, and then will take advantage of a spherical model with central core instead of a linear model. These units, with regard to the required time of implementation, will surround this core as in the form of some layers. The circuits are ordered in a way that the further we move from the core towards the external layers, the shorter the required time of implementation will become. This way, the priority of implementing ERP will be assigned with a direction from external layers to internal layers. Eventually, all the experiences of the previous stages will be transferred to the central core, which has the most complexity. Through this method, it is expected that we may prevent the fully parallel issue, which was a dominant and apparent issue in previous models, so that the required time of implementation would decrease.展开更多

This paper first discusses potentials of solar technology in terms of global availability using PV （photovoltaic） technology and actual energy production. Solar energy is widely under-used and one way to reduce this is to improve production in low-energy places with high demand： large cities. According to this option, about 40% of the electricity consumption in the built environment could be produced by solar PV systems and energy storage systems. This paper discusses conditions in the built environment and functional and design qualities enabling an increased diffusion of the technologies In a comparative analysis of PV technologies, the criteria taken into account encompass efficiency of the type of solar cell and commercial availability. Special attention is paid to the design features of different PV systems, like flexibility, colour and transparency that might help in their utilization as integrated in building material and ornaments in modem architecture. The same procedure is followed for electricity storage devices. The preliminary conclusion is that at present the freedom of design is largest for a combination of crystalline silicon PV cells and Li-ion batteries.展开更多
