The effect of wall and floor colouring on temperature and draught feeling of primary school children

To investigate whether different colours of the indoor surfaces could have an effect on thermal comfort of children, 335 primary school children were invited to take part in a series of tests conducted in the thermal test chamber of the SenseLab. A three-way factorial randomized design was used to test the effect of three different colours of walls (white, red and blue) and floor (grey, green and blue) on the temperature and draught feeling in a winter situation (sunlight coming in: heat) and a summer situation (opening window: draught). A statistical relevant relationship between feeling of draught and feeling of temperature was found. Except for a significant difference in temperature feeling for different floor colours when the wall colour was red in the winter situation, no relevant effects (or interaction effects) were found for differences in wall or floor colours on the temperature or draught feeling.
