The purpose of this paper is to make an abridged description of a desirable design solution for primary schools in rural areas,based on ancient constructive techniques with the necessary contemporary adjustments by using only locally extracted materials and employing local labour force,and define future bioclimatic design strategies applicable to the cases of S(a)o Tomé and Príncipe and East Timor.Both regions are located in the hot and humid climate zone,characterized by intense solar radiation,small daily temperature ranges,high humidity and seasonable moderate winds,which as a whole influence the level of comfort inside buildings.Thus,from a background analysis of S(a)o Tomé and Príncipe and East Timorese territories and,in particular,of their climate,natural resources and socio-economic environment,an attempt was made to prove that it is possible to achieve a thermal comfort through the application of a series of design strategies – referred to as bioclimatic or of passive design,which should be a major concern to be considered in the construction of these schools.To this purpose we developed a conceptual model using the DesignBuilder and Ecotect software,which under bioclimatic architecture enabled an expeditious modelling,in elementary terms,of the energy performance and the environmental comfort.In conclusion,a set of passive design recommendations is herein proposed,applicable to the construction of new schools with full autonomy of local population,which may provide a significant contribution to a sustainable development and change the constructive paradigm of the countries.
