Acceptable temperature ranges in naturally ventilated and air-conditioned offices
- Building Research Establishment, Watford (United Kingdom)
The thermal environment in eight naturally ventilated and eight air-conditioned offices, located throughout England, was continuously monitored for one week in winter and one week in the following summer. The occupants assessed their thermal sensation (TS) every half-day on the ASHRAE seven-point scale. In total, 1,692 occupants made 11,450 votes in winter and 1,363 people made 9,505 votes in summer. Weighted regression analysis was used to compute the neutral temperature and acceptable temperature range relating to 3.5 {le} TS {le} 4.5. In winter, the percentage of occupants satisfied with the temperature in the naturally ventilated buildings (76%) was higher than in the air-conditioned offices (70%), whereas in summer, there was less satisfaction in the naturally ventilated offices (69%) than in the air-conditioned offices (73%). The occupants were less dissatisfied in the naturally ventilated buildings in winter than in summer, whereas there was only a marginal difference in dissatisfaction between seasons in the air-conditioned offices.
