摘要: The effects of reduced summer indoor temperature, through renovation an HVAC system, on symptoms, perceived environment and productivity in office building are investigated. Measurements parameters, were conducted over two successive summers. Two floors the renovated during wintertime. mainly consisted cooling supply air, installation ceilings about half rooms, distributing air to all rooms. An questionnaire assessing current symptom intensity, including questions self-estimated work efficiency, was presented employees five days each summer. measurements taken before showed that temperatures rose above thermal comfort levels (maximum temperature 31.4°C). When 25°C, neurobehavioural symptoms percentage those dissatisfied with quality increased...
