In this paper, we declare the intensity of solar radiation, UV strength, inside temperature, humidity, illumination intensity, CO and CO2 concentration field measurements for apartment building located in Tibet's capital and in traditional houses in order to evaluate their levels in the living environment. The Tibetan plateau is characterized by high altitudes, low oxygen concentration, atmosphere is transparent, wide diurnal range temperature, special culture and life style, so UV and solar radiation, thermal environment and IAQ are claimed attention. Also the questionnaire survey was carried out jointly with Xi'AN University of Architecture and Technology for considering improvements.
