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.

Whether a journey is pleasant or not usually depends on the climatic conditions which permit to perform outdoor activities. The perception of climatic conditions, determined by physiological and psychological factors, can vary according to different adaptation phenomena related to the person involved and the weather conditions of the place where they live. Studying the bioclimatology of a country characterized by a high flux of tourism, as e.g. Italy, can provide some important information about where and when is it better to visit a place.
