Thermal Comfort Enhancement for Office Blocks Considering Employees' Satisfaction Without Increasing Energy Consumption

In Jordanian building sector, a high percentage of cooling and heating energy is consumed. However, the occupants<acute accent> satisfaction regarding indoor thermal comfort is low as mentioned in previous studies. This study investigated the indoor thermal comfort and energy consumption at three zones in the office block before and after implementing corrective actions (CA) for enhancing thermal comfort level. Therefore, it is assumed that implementing CA will increase employees' satisfaction without increasing energy consumption, ASubsequently, that improve their health, Aperformance, and productivity. A mixed approach is used to collect data by using experimental investigations and interviews. The employees' satisfaction was evaluated in two phases: before and after the implementation of CA. The study showed that employees' satisfaction increased, while the indoor ambient temperature (IAT) decreased to become closer to thermal comfort level without increasing the energy consumption ratio. AFurthermore, changing functions during the construction phase represents a major challenge that affecting occupants' thermal comfort negatively. Finally, using isolated aluminum window frame or PVC windows instead of using traditional aluminum window frame is recommended as the results showed.
