The influence of different ground surface boundary conditions on the efficiency of a single earth-to-air heat exchanger as well as of a multiple parallel earth tubes system has been investigated. The cooling potential of both these systems buried under bare soil has been assessed and compared...

Ten years' hourly measurements of air and ground temperature values at various depths below bare and short grass soil at Dublin Airport have been used in order to investigate the impact of different ground surface boundary conditions on the efficiency of a single and a multiple parallel...

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 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...

In the field of energy savings in buildings, the interest towards the school sector is deeply motivated: schools have standard energy demands and high levels of environmental comforts should be guaranteed. The University of Athens in collaboration with the School Authority of Greece undertook a...

An aluminium nocturnal radiator, painted with an appropriate white paint, was established on the roof of the Department of Environmental and Natural Resources Management in Agrinio, Western Greece. The lightweight metallic radiator was used for cooling the ambient air below its initial...
