Research on psychological factors related to employee’s decision makings about energy conservation within organizations is limited. This study used attitudinal (internal) and external determinants by using quantitative analysis to better predict workers energy saving behavior at workplace. The goal of this research was to observe behavioral impact on office occupant’s energy saving efforts and their ease of communication within office settings about energy use at workplace. We examined the individual and organization level factors related to energy conservation behavior at both government and private sector offices. We found that an employee having only Energy Saving Belief (ENSB) that does not leads to greater change in behavior. While office occupants who strongly believed that energy conservation is beneficial for environment (ECBE) have willingness to save energy at some cost of personal comfort and find it easy to communicate with colleagues about energy use pattern. Participants of the survey who actually think comfort is tied to their productivity at work reported less willingness to conserve energy in summers but in winters have shown positive relationship with (1) Willingness to save energy; (2) willingness to save energy in winters (3) Perceived ease to communicate. Group norms and organizational support predicted no influence on energy saving behavior. The study demonstrates a path for future research to consider psychological factors having effect on energy saving behavior. Supervisor:- Dr Muhammad Nasir
