Results show the following: (1) In smaller buildings (〈 5,000 m2), setting temperatures are higher in summer and lower in winter, effects of "uncomfortable radiation from windows" are greater, energy-saving systems decrease indoor thermal comfort, but claims of "hot" and "cold" are fewer; (2) Claims of "hot" and "cold" are unrelated to the setting temperature and whether the air-conditioning control system is central or local; (3) The adoption rates of mitigation of dress codes ("COOL-BIZ" and "WARM-BIZ") are higher than those of temperature mitigation of air conditioning.展开更多

The investigation results showed that the average intensity of energy consumption in office buildings in Tianjin accounts for 161.51 kW-h/(mZ.a). By breaking the energy consumption down into detailed items, it was found that the heating system consumed the highest amount of energy (46.6%), followed by equipment (35.9%), cooling system (11%) and lighting system (6.69%). The main factors for office building energy consumption were found and some feasible measures to save energy were proposed.展开更多
