Even if current action towards sustainability in architecture mainly concerns single buildings, the responsibility of the urban shape on local microclimate has largely been ascertained. In fact, it heavily affects the energy performances of the buildings and their environmental behaviour. This produces the necessity to broaden the field of intervention toward the urban scale, involving in the process different disciplines, from architecture to fluid dynamics and physics. Following these ideas, the Masterplan for the Campus of the University Eduardo Mondlane in Maputo (Mozambique) develops a methodology that integrates microclimatic data and analyses from the initial design model. The already validated software ENVI-met (Version 4.4, ENVI_MET GmbH, Essen, Germany) acts as a useful ‘feedback’ tool that is able to assess the microclimatic behaviour of the design concept, also in terms of outdoor comfort. In particular, the analysis focused on the microclimatic performances of a ‘C’ block typology east oriented in relation to the existing buildings, in Maputo’s specific climatic characteristics. The initial urban proposal was gradually evaluated and modified in relation to the main critical aspects highlighted by the microclimatic analyses, in a sort of circular process that ended with a proposed solution ensuring better outdoor comfort than the existing buildings, and which provided an acceptable balance between spatial and climatic instances.

Because of his classification as a minor architect, Gaetano Vinaccia’s (1881–1971) role in the history of architecture has not been studied in depth. Despite the fact that his impact on the debate about rational architecture was limited, the depth and scientific accuracy of his theoretical contribution to the field of microclimatology in relation to urban design issues deserve to be highlighted, especially today when environmental and bioclimatic questions arise strongly in architecture and planning. Thus, this work aims to reconsider this figure by describing the—unfavorable—context in which his work evolved, by bringing to light his most brilliant statements, by reading his scientific productions, and by starting to consider the validity of some of Vinaccia’s intuitions and their actual correspondence with contemporary research. The question of whether Vinaccia can be considered as an innovator (or not) largely derives from the point of view of architectural criticism and the fact that he did not have a well-defined discipline in which to be classified. Despite the fact that his The City of Tomorrow (1943–1952), which is the first complete treatise on the subject, reveals that he was an absolute pioneer, he has had no chance to influence architecture and urbanism until today.
