Thermal Comfort Conditions
Percentage of comfort in relation to thermal sensation
Local cooling of the body seems to more frequently cause discomfort than local heating. Local discomfort was found either as warm head or cool feet.
Heating glass is the only way of solving problems caused by low surface temperatures of glass windows.
Testing conducted by Laborelec Brussels and by CEBTP France, showed the efficiency (the part of the energy input that is pulsed into the room as heat) of an IQRG window is excellent, at least 93 %, due to the low emission glass.
This means that the produced energy is used to heat the room with a minimal amount of losses.
