This paper focuses on the assessment of possibilities to subsidize the purchase and installation of solar collectors in Poland by government or local government grants and special funds designed for this purpose. It analysis of costs and profi ts resulting from the application of solar installations in the process of heat generation for household requirements, by calculating the payback time, w...

i ABSTRACT This thesis provides a cost to benefit analysis of the proposed next generation of distribution systems-the Future Renewable Electric Energy Distribution Management (FREEDM) system. With the increasing penetration of renewable energy sources onto the grid, it becomes necessary to have an infrastructure that allows for easy integration of these resources coupled with features like enh...

I will not be too long before rooftop solar panels will become a preferred option for new construction of houses in the U.S. and elsewhere. Many recent projections of new energy installations predict a surge in wind and photovoltaic (PV)based installations during the next 25 years. The availability of affordable PV panels is rendering the installation of solar panels on residential rooftops a m...

Despite being rejected by finance theory, payback continues to be widely used as a method for evaluating capital investment projects. In situations where investment can be delayed, we show that the value of waiting to invest is an increasing function of payback period. Consequently, the optimal investment policy is equivalent to requiring that a project with positive net-present-value be launch...

This paper presents a thermoeconomic analysis aimed at the optimization of a novel zero-CO2 and other emissions and high-efficiency power and refrigeration cogeneration system, COOLCEP-S (Patent pending), which uses the liquefied natural gas (LNG) coldness during its revaporization. It was predicted that at the turbine inlet temperature (TIT) of 900 C, the energy efficiency of the COOLCEP-S sys...

the municipality of tehran is intending to construct a permanent international flower exhibition. the activities for construction began in the year 2006. the exhibition has three distinct areas namely “northern area”,”southern area” and “central area”. in northern and southern area the flowers are supposed to be preserved and in central area, they will be sold out. in the present st...

This paper presents a framework and results of using model-based design (MBD) methodology to evaluate the benefit and trade-offs of different chiller plant control algorithms for medium-sized commercial buildings including an optimization-based algorithm that can be deployed rapidly with little installation and commission effort. A highfidelity dynamic simulation model for selected building typ...
