“…The overall efficiency of such systems, referring to both electricity and heating production, can be in the range of 95% [13]. In common implementations, CHP systems are proposed for commercial and residential buildings for combined heat and electricity production [15,16]. In advanced applications, the combined operation of CHP systems with thermal energy storage have been studied [17] aiming at the minimization of the daily operation cost.…”

Energy performance upgrade of stadiums constitutes a complex and demanding task because of both the size and the variety of the involved energy loads. The present article aims to summarize the basic results of the implemented study on the energy performance upgrade of the Pancretan Stadium, Crete, Greece. This target was approached with a cluster of passive and active measures: replacement of old openings, a photovoltaic station, an open loop geothermal system, installation of energy-efficient lighting devices, a solar-biomass combi system and a Building Energy Management System (BEMS) for the control of the main energy consumptions. The dimensioning of all the proposed active systems is optimized through the computational simulation of their annual operation. With the applied technologies, the achieved annual energy saving percentage exceeds 83%. The Renewable Energy Sources annual penetration percentage is calculated at 82% versus the annual energy consumption. The Stadium’s energy performance is upgraded from rank D to rank A+, according to the European Union’s directives. The set-up cost of the under consideration energy performance upgrade systems is approximately calculated at 2,700,000 €, with a payback period of 12 years, calculated versus the achieved monetary savings due to the reduction of the consumed energy resources.

“…This combined method is known as exergoeconomics, and is commonly used in power plants and chemical processes for system optimisation. While some researchers applied exergoeconomic analysis to buildings [23][24][25][26][27][28][29][30][31][32], the analysis is often limited to only a single system design. In addition, these studies also showed that the reference temperature (normally outdoor temperature) is the most sensitive parameter, thus having the biggest effect on thermoeconomic results.…”

The paper describes a systematic framework that uses exergoeconomic theory integrated into 'building energy retrofit' (BER) design. An exergoeconomic module, based on the SPECO method, has been embedded into 'EXRETOpt', a recently developed retrofit-oriented exergy simulation tool based on EnergyPlus. Both active and passive technologies were analysed using two calibrated archetype non-domestic buildings as case studies (an office and a primary school). A novel cost-benefit indicator which accounts for building exergy destruction cost, retrofit annual capital cost, and project annual revenue is presented. This indicator is employed to account for best exergoeconomic performance technologies and to further develop deep BER packages. Compared to typical practice, exergoeconomics combined with cost-benefit provides a powerful tool for exploration and design improvement of building energy systems. In both cases, final product cost for heating and cooling processes were substantially reduced. In addition, the office case presented improvements in energy use by 67%, CO2 emissions by 53%, thermal comfort by 22%, exergy destructions by 42%, and the overall building exergy efficiency was improved from 14.8% to 20.0%. The school case presented similar results with an improvement of building exergy efficiency from 8.2% to 11.1%, and the potential to generate income due to current government incentives.

“…To resolve the reliability and accessibility problems of solar energy, hybrid power generations are used broadly, [4]. A main method of increasing the productivity of solar systems is to extend them to combined heat and power generation (CHP) [5]. Solar CHPs could reduce the greenhouse gas emissions far faster than the conventional solar energy devices, and maximize the economic and environmental value of the energy derived from the sun.…”

A main method to increase the solar energy utilization efficiency is to combine heat and power generation together. In this paper, a critical review of the literature on solar combined heat and power systems (CHP) is conducted, which includes solar photovoltaic/thermal systems, concentrated photovoltaic/thermal systems, and various combination with different solar collectors and applications. It shows that there are serious gaps in this field, which calls for more research. The modeling and analysis of the electrical parts of the CHP systems are not adequate, and there are limited studies on the economic and exergy assessments of the solar concentrating CHP systems. The solar collectors for combined CHP were focused on optimizing the performance of the maximum average useful power generation and minimum total heat transfer area, little environment impact analysis was conducted. Careful exergy, economic and environmental analysis on both electronic and thermal performance is suggested, especially for large CHP system.
