thermal perception

On the necessities to analyse the thermohygrometric perception in aged people. A review about indoor thermal comfort, health and energetic aspects and a perspective for future studies

This study wants to examine the current bibliography concerning the thermohygrometric perception in aged people living in industrialized countries and its socio-economic consequences. Nowadays the number of European people between 70 and 90 years old is increasing, thus causing an aging of the average population. A proper and modern planning of indoor environments in residential buildings requires the presence of a good thermohygrometric comfort together with a low energy consumption level.

Influence of lighting colour temperature on indoor thermal perception: A strategy to save energy from the HVAC installations

This paper examines how the lighting colour temperature affects indoor thermal comfort. A test room with three separate environments was set and, in each one of them, a lamp with a different colour temperature was positioned to evaluate the influence of a cold, neutral and warm light. The colour temperatures of the used lamps were 11,530 K, 4,000 K and 1,772 K respectively. During each test, while complying with the EN 12464-1, a lighting level of 500  lx and a uniformity coefficient higher than or equal to 0.7 were maintained.
