The Netherlands Agency for Energy and the Environment(NOVEM) is conducting a program for the implementation of Low Temperature Heating (LTH) systems in buildings. The primary goal is to enable the use of Low Talued Energy as a heating source. Major savings in enery consumption can be realised by fully utilising the potential of Low Valued Enery. Besides the argument of savings in energy supply, there are additiond benefits in the fields of. Indoor Air Quality (particles, mites, lower air temperature, annoyance and dust);. Thermal Comfort (radiant heat, temperature gradient, radiant heat asymmetry, floor temperature, temperature fluctuations, heating up period, cooling, air velocities and draught);. Energy Consumption (transmission/venting losses, transport energy, utilisation of gains).This study (lit ) shows that by lowering the temperatures for heat distribution systems, mainly advantages on the above mentioned aspects were found. By highlighting these additional benefits an easier introduction of LTH-systems might occur. Application on abroader scale will also lower the prices of these systems.
