Abstract: A simple modular constructive system based on gypsum blocks is presented. It is argued that this constructive system reduces the manpower considerably, the time of execution and the final costs of construction. This is particularly important in a country whose objective is to achieve, until the end of 2014, 3 million of new dwellings. However, the durability assessment should be analysed but first its implementation and performance along the country must analysed.

The hygrothermal performance of the gypsum house was assessed by advanced modelling, using the EnergyPlus software. The numerical results carried out allow a discussion over the interior comfort and durability of this modular constructive system.

In this paper, the computer simulation model and the results of a parametric analysis of the dwelling performance on the eight climatic regions defined in Brazilian regulations are presented. The model was validated using the in situ measurements of air temperature.

Results showed that the modular gypsum house can be an interesting solution for Brazil, however improvements and adaptations need to be made in specific regions.
