The technology, integrated security, and communication systems building-oriented had a great evolution in the last decades. Likewise, the energy efficiency concepts and the greater concern related to sustainability in the civil construction sector have both been enlarged. Although buildings certified as intelligent have gained more prominence in recent years, their highlight is still minor considering that they are one step ahead of those certified as sustainable due to improving technology and tools to achieve maximum energy efficiency. In this context, this work aims at providing a foundation for a better understanding of the various parameters required for the transition from a sustainable building certificated to an “smart building”, using the Smart Readiness Indicator (SRI) as a reference. To this end, a checklist was proposed to better guide the transition from sustainable to smart. Moreover, a Leadership in Energy and Environmental Design (LEED) certificated building located in Belo Horizonte, Brazil, was taken as the object of study to assess its potential to meet the requirements of building intelligence. The results revealed that the building sustainable certification of LEED does not ensure that it reaches a significant potential for intelligence, but it contributes to the fact that part of the criteria required for its transition is already being met. In general, it is understood that the proposed checklist may be also applied in other cases to assist in the purpose of analyzing the transition from efficient to smart buildings through the analyzed parameters, as well as contribute to a new generation of automated and ecologically sustainable buildings.

Diversos regulamentos de eficiência energética e ambiental têm sido aplicados para certificação do patrimônio edificado. Neste trabalho, buscou-se comparar os critérios exigidos em dois referenciais edilícios proeminentes no Brasil: RTQ-C (Regulamento Técnico da Qualidade para Nível de Eficiência Energética de Edificações comerciais, de Serviços e Públicas) e LEED (Leadership in Energy and Environmental Design), aplicados a uma edificação pública escolar existente. Constatou-se que o atendimento aos pré-requisitos para classificação máxima pelo RTQ-C não é suficiente para possibilitar a certificação mínima pelo LEED. Para tanto, adequações ao edifício seriam necessárias, as quais poderiam acrescer cerca de 2,54% no custo total de construção do edifício. Portanto, este trabalho mostrou relevância acadêmica, ao incentivar o desenvolvimento de pesquisas científicas acerca da sustentabilidade nas universidades, além de identificar uma solução prática para um problema real. A metodologia pode servir de base para estudos semelhantes.
