The indoor overall environmental comfort of part limited spaces is studied in this paper. The operative temperature, illumination, and noise intensity are used as objective parameters in order to evaluate the thermal, luminous, and acoustic environment. The thermal, luminous, and acoustic environment are investigated by using the subjective questionnaire in this experiment, and the function rel...

OBJECTIVES This report describes physiological and behavioural mechanisms behind the control of body temperature and thermal comfort during competitive singles tennis. METHODS Thermoregulatory responses and workload were observed during "best of three sets" tennis matches among 25 players. In total, 94 matches were played in ambient temperatures ranging from 14.5 to 38.4 degrees C. The therma...

The effects of task-ambient (TA) air-conditioning systems on the air-conditioning loads in small and large spaces and the thermal comfort of occupants were studied using computational fluid dynamics (CFD), pedestrian-behavior model, and refrigerating-cycle simulator. Task areas were set up to match with crowdedness as predicted by the pedestrian-behavior simulations. Subsequently, a variety of ...

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

The design of buildings is a multi-criterion optimization problem, there always being a tradeoff to be made between capital expenditure, operating cost, and occupant thermal comfort. This paper investigates the application of a multi-objective genetic algorithm (MOGA) search method in the identification of the optimum payoff characteristic between the elements of the building design problem. Re...

This paper presents a thermal comfort analysis in outdoor spaces of low-income housing projects in Londrina city, Brazil. The objective is to improve the identification of client requirements in the design development process, in order to satisfy thermal comfort requisites of low-income housing users. It has been proved that human settlements quality is intimately linked with thermal comfort an...

Outdoor spaces play important roles in daily lives, and the use of these spaces is determined largely by outdoor thermal comfort. Few studies have been conducted on outdoor thermal comfort in northern China. Using microclimatic monitoring and subject interviews at a park in Tianjin, China, this investigation studied outdoor thermal comfort under different climate conditions. Although outdoor th...

The influence of different experimental conditions on the thermal comfort behavior of polyester-viscose and polyester-cotton ring and MJS yarn fabrics has been studied. The results show that the yarn structure and the fibre cross-sectional shape have a large influence on improving the thermal comfort of woven fabrics. The fabrics made from MJS yarns perform better than those of the ring yarn fa...
