The article presents an analysis of the energy retrofit of the Support Center for Technological Development (CDT) building at the University of Brasília (UnB), aiming to transform it into a Zero Energy Building (ZEB). The methodology was based on computer simulations carried out using DesignBuilder software (version 7) to evaluate passive and active strategies, such as solar control, efficient lighting systems, and renewable energy generation. The study considered the typical climate of Brasília. The results indicated that, after the interventions, energy demand was reduced by 42.65%, reaching 139,010.84 kWh/year, with more than 90% of the hours within thermal comfort, even without the use of air conditioning. The estimated energy generation was 161,850 kWh/year, exceeding consumption and ensuring a positive energy balance. The study demonstrates the feasibility of applying sustainable solutions to existing buildings, highlighting the potential of retrofit as an effective tool for the energy transition in the built environment. The adopted strategies can be replicated in similar buildings, contributing to energy efficiency and institutional sustainability.
