This paper deals with the experimental investigation and analysis of the energy and environmental performance of a green roof system installed in a nursery school building in Athens. The investigation was implemented in two phases. During the first phase, an experimental investigation of the...

The radiative cooling potential is determined by the ambient temperature, relative humidity, wind velocity, and cloudiness. Previous assessments of the radiative cooling potential in Greece have been based on mean weather data. In this paper, 12 years of hourly weather data are used to assess...

School buildings (238) in Hellas were audited for construction, heating, cooling, lighting, and mechanical and electrical systems. The annual average total energy consumption is 93 kWh/m2, of which approximately 72% is consumed for space heating. The assessment of various energy-conservation...

The resource base for RES is vast, but only a small fraction is being exploited with available technology. The full potential of RES for the European Union (EU) is estimated at 408 Mtoe by 2020. Here, we review data on energy supplies and demand with emphasis on RES and also assess the potential...

A numerical model to calculate the performance of multiple, parallel, earth-to-air heat exchangers is described. The system consists of N parallel earth tubes, buried in the ground, through which ambient or indoor air is propelled and cooled by the bulk temperature of the natural ground. The...

This paper deals with the problem of the identification and the thermal regulation of a solar paraboloidal collector. First, a short description of the experimental process is given and former modelling results are presented. Then, using experimental data, a bilinear model for the receiver of...

The use of buried pipes reduces the energy consumption for heating of agricultural greenhouses by increasing the air temperature and also improves indoor conditions by reducing temperature fluctuations during the day. A parametric analysis has been performed for a typical glass greenhouse to...
