In the teaching of Architecture in Portugal, the practices introduced by Frederico George, and later developed by Daciano da Costa, also reinforce the importance of the craft regarding the teaching of Drawing.
In 1992, he started and directed the first Degree in Design Architecture, at the Faculty of Architecture of the Technical University of Lisbon, where he taught until retiring in 2003. In 2004, he was awarded the title of Doctor Honoris Causa by the University, for the contribution of his work in favor of the Design development in Portugal. The previous year he had received an equal distinction by the University of Aveiro.
In 2001, the National Society of Fine Arts awarded him the medal for members with more relevance in the life of the institution, and the Portuguese section of the International Association of Art Critics awarded him with the annual prize for Architecture.
The Order of Architects named him honorary member in 2002, the year before the President of the Republic had imposed on him the insignia of Commander of the Order of Infante D.Henrique, an award that unifies with the one of Great Officer of the Order of Merit, received in 1995.
In 2003, the General Direction of National Buildings and Monuments integrated a substantial part of Daciano da Costa's archive, consisting of sketches, technical drawings, and models resulting from his design project activity until 1994.
