Abstract: In air-conditioned university teaching rooms, air-conditioning systems have contributed to a large portion in the overall energy consumption. To reduce carbon dioxide emissions contributed to global warming, thermal energy conservation in air-conditioned space should be taken into account. However, a good air-conditioned indoor environment is needed for high learning performance of students. This study investigates the relations between thermal energy consumption and the learning performance of students in air-conditioned university teaching rooms. In evaluating the learning performance loss of given indoor environments, a previous study concerned with the relations between indoor environmental quality and student learning performance were used as reference. Occupants' response in thermal comfort and indoor air quality are two necessary indoor environmental factors considered in determining thermal energy consumption and learning performance loss. Since poor thermal comfort and indoor air quality would result in reduction of learning performance, some indoor environmental conditions suggested by the Government are examined with regard to thermal energy consumption, CO₂ emissions from electricity consumption and learning performance loss due to thermal comfort and indoor air quality. In a teaching room, their relations can be represented by environmental efficiency, which is illustrated by the learning gain corresponding to its CO₂ generation due to electricity consumption of air-conditioning system. The results revealed that there are improvement potentials on the environmental efficiency of indoor environmental conditions suggested by the Government. This study provides reference sources on the relations between thermal energy consumption, CO₂ emissions and learning performance loss in air-conditioned teaching rooms in sub-tropical regions.
