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...

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...
