SUMMARY:

Aiming at providing answers to global problems, such as housing shortages, American Richard Buckminster Fuller sought solutions in construction, through a creative and systematic process, to meet the needs of users. Thus, he developed the geodesic dome, a structure with geometry similar to a sphere, which presents structural and aesthetic efficiency, a high ratio between internal volume and external surface, smaller thermal exchange surfaces with the external environment, which can positively influence the thermal performance of the envelope. The thermal properties of the materials used in geodesic domes have an important impact on the thermal performance of the construction and consequently on the comfort of users. The general objective of the work is to present a proposal for housing of social interest, in the form of a geodesic dome, with a wooden structure and envelope, adaptable to different Brazilian bioclimatic zones. The specific objectives concern the conception of the preliminary project and meeting user requirements relating to habitability, namely: analysis of the thermal performance of the envelope, analysis of users' thermal comfort, analysis of lighting performance and ventilation analysis. The assessment of the minimum level of thermal performance was carried out using the simplified procedure recommended by ABNT NBR 15575-1:2021; the evaluation of intermediate and higher levels will be done by computer simulation. Users' thermal comfort will be evaluated in two stages: adaptive model from ASHRAE 55 (ASHRAE 2010) and static model from ISO 7730 (2005) which allows calculating the estimated average vote indexes (PMV) and the percentage of people dissatisfied with the environment (PPD). To analyze the lighting performance, the DIAlux software will be used. Ventilation analysis will be done using Computational Fluid Simulation (CFD). The preliminary results of the thermal performance assessment showed that the thermal transmittance parameters of the wall (Upar) and roof (Ucob), natural ventilation percentages (Pv,APP) and transparency percentages (Pt,APP) were met; and that the thermal capacity of the wall (CTpar) was below the limit recommended by the Standard. Given these results, the need for computer simulation to access the annual performance of the building was confirmed. Based on the assessment of thermal performance through simulation, the aim is to propose adjustments to the housing's construction systems in order to adapt it for implementation in different Brazilian bioclimatic zones. As a result of the research, it is expected that the social housing proposal meets the user's habitability requirements, presents a balance between cost and benefit and can be adapted to different bioclimatic zones.
