Designing buildings has faced dramatic changes during the 20th century. As buildings reached greater heights, Heating, Ventilation and Air Conditioning (HVAC) systems became essential to assure comfortable indoor environments. This practice led to a significant increase in energy consumption. As researches show this demand will keep growing, the pursuit for energy efficiency strategies is now mandatory in construction. Existing buildings are a substantial part of this quest for better performance in energy, thus, they must meet the new quality standards through rehabilitation. Thereby, the study assessed the energy saving potential in a corporate built complex in Belém-PA, in order to apply retrofit concepts. The study used the Post-Occupancy Evaluation methodology to understand users’ behavior and their adaptability to different environmental conditions. Following, Energy Conservation Opportunities (ECOs) were proposed, whose savings and payback were calculated. 14% of projected savings were provided on monthly energy consumption, with a payback of 2.22 months.
