In this paper was calculated the return period of coastal floods for each of the coastal settlements that report this extreme event in the Cuban archipelago, based on the period 1901-2020. The chronology and classification of coastal floods for each province was used, as well as the Poisson distribution and the χ² goodness of fit test. It is concluded that the Poisson distribution was suitable in all cases for the significance level of 5%; while the greatest hazard is presented by Havana, Baracoa and the settlements of the Gulf of Batabanó in which the occurrence of a flood event is expected at least once every three to five years.

This paper reports the results of research conducted in order to propose a system of lightweight sun protection devices that can be produced in Cuba and added to the facades of the buildings in order to reduce the heat load through the architectural envelope and the energy consumption. For this, a modular indoor air- conditioned space with three possible functions, of which the requirements were derived to satisfy the elements of sun protection design, was defined. Its performance in terms of reduced heat transfer and natural lighting inside was assessed using automated simulation with Ecotect V5. The application in a case study helped to show that the required investment for the solar protection of the building facade can be amortized in less than two years from reducing air conditioning load.
