This paper aims to address the characteristics of urban microclimates that affect the building energy performance and implementation of the renewable energy technologies. An experimental campaign was designed to investigate the microclimate parameters including air and surface temperature,...

The main object of this paper is the documentation and study of the main factors behind the spectacular diffusion of solar energy use for domestic hot water production in Greece. The time pattern of the diffusion of flat-plate solar collectors since its ‘out of the blue’ first appearance in...

This paper proposes a cheap, maintenance-free generator suitable for maximum wind energy capture. It can be designed for low speed applications, where it could be rigidly coupled to a Sandia-17-m Darrieus wind turbine without the need of a gearbox. The generator is operated at varying shaft...

In this study, a thermodynamic analysis of a gamma type Stirling engine is performed by using a quasi steady flow model based on Urieli and Berchowitz's works. The Stirling engine analysis is performed for five principal fields: compression room, expansion room, cooler, heater and regenerator....
