Starting in 2027, all new federal public buildings in Brazil will be required to meet minimum energy efficiency criteria.
This measure is part of a resolution from the Ministry of Mines and Energy (MME) that establishes a timeline for expanding the adoption of more sustainable standards in public and private buildings.
Pela standardBuildings must meet minimum energy efficiency ratings on a scale ranging from A, the most efficient, to E.
Among the solutions planned to improve the energy performance of buildings are the installation of motion sensors for lighting, the use of LED lamps in common areas, and the implementation of photovoltaic systems.
According to the Ministry of Mines and Energy (MME), the expectation is that the new regulation will generate savings of almost 3 million MWh by 2040 in public buildings alone.
The University of Brasília (UNB) is one example of the early adoption of these measures. On one of the institution's campuses, the buildings were designed with solutions focused on internal thermal control, including aluminum sunshades and solar panels.
According to the university, the measures helped reduce monthly energy costs from approximately R$ 90 to R$ 5.
Next Steps
The plan defined by the Ministry of Mines and Energy also foresees a gradual implementation of the new guidelines over the next few years.
Starting in 2030, the criteria will apply to new commercial and residential constructions in cities with more than 100 inhabitants, as well as social housing projects financed with public funds.
In 2032, the requirements will be expanded to include new state-owned public buildings. Then, in 2035, the rules will also cover municipal public buildings in cities with more than 100 inhabitants.
By 2040, all new public, commercial, and residential buildings located in municipalities with more than 50 inhabitants must meet the minimum energy efficiency standards established by the Ministry of Mines and Energy (MME).

An answer
I published an article in 2002 desperately warning the GOVERNMENT about the trillions they were losing and would lose if they didn't renovate all public buildings before 14.300.
