It binds building design and retrofit of public buildings with more than five hundred square meters of area, to be developed according to the National Label of Energy Conservation level A of the Technical Standards for the Quality of Commercial, Services and Public Buildings (RTQ-C). This paper’s objective is to verify if the energy efficiency level in classroom buildings, which were bidden by Federal Institutions of Higher Learning (IFES), meets the NI’s resolutions and, if not, how they can be improved. Following RTQ-C’s protocol, ten naturally ventilated buildings, bidden by four different IFES, were analyzed. Simulations were run verifying the hypothetical energy expenditure if the buildings were air-conditioned. As a result, 60% of the buildings met the highest grade of energy efficiency, complying with the NI. In non-compliance, small modifications such as the replacement of fluorescent light tubes by LED lights and dual flush toilets are enough for the projects to reach the level A-label. Em 2014, foi publicada a Instrução Normativa 02/2014, do Ministério do Planejamento, Desenvolvimento e Gestão, obrigando os projetos de edificações e os retrofit de edificações públicas federais, com mais de quinhentos metros quadrados de área, a serem desenvolvidos buscando a Etiqueta Nacional de Conservação de Energia de Projeto nível A, de acordo com os Requisitos Técnicos de Qualidade para o Nível de Eficiência Energética de Edifícios Comerciais, de Serviços e Públicos (RTQ-C). O objetivo deste trabalho é verificar se projetos de prédios de salas de aula licitados por Instituições Federais de Ensino Superior (IFES) atendem à determinação da IN 02/2014 e, em caso negativo, como intervir para os projetos atingirem nível A. Foram analisados dez prédios naturalmente ventilados licitados por quatro IFES do Rio Grande do Sul,  seguindo os procedimentos indicados no RTQ-C. Também foram realizadas simulações para verificar o consumo hipotético de energia se os edifícios fossem condicionados artificialmente. Como resultado, 60% dos projetos conseguiram alcançar o nível mais alto de eficiência energética, atendendo à Instrução Normativa. Também se verificou que, nos casos negativos, a substituição das lâmpadas tubulares fluorescentes por lâmpadas LED equivalentes e especificação de bacias sanitárias econômicas bastaria para os projetos obterem a classificação máxima.
