If renewable energy sources are to be successfully utilised within the built environment then accurate simulation tools have an important role to play. This paper addresses a very specific part of the overall simulation process: that of earth-contact heat transfer which can be the cause of...

On the basis of their thermodynamic properties and their historical development, some “Strength-Ideas” proposed which lead to the conclusion that, properly designed, heat pumps have a good future and will contribute to lessen the global CO2 emission burden.
