heat-flux

Heat flux is the rate of energy transfer through a given surface. This quantity can be measured using a heat flux sensor. The measurement of heat flux is of importance to many sciences. Most common applications are in building physics, where the heat flow through walls is one of the factors determining the indoor climate, in agricultural meteorology, where the heat flux into the soil is a parameter in the study of evaporation of water, and biology to measure heat flux from humans or animals. The accurate measurement of heat flux can lead to energy saving in buildings and to more efficient use of water in irrigated agricultural area's [http://www.hukseflux.com/heat%20flux/flux.htm]
