The thermal behavior of three different walls, made with and without by-products, is assessed by means of the Finite Element Method, aiming to evaluate its performance in terms of the sustainable construction of the blocks. Results were compared to those obtained from an experimental campaign, aiming at validation of the model. The by-products used for the blocks were “lime sludge” and “sawdust”, whose performance was compared against the traditional blocks made of concrete as a reference, aiming to demonstrate its sustainability, showing decreases of the thermal transmittance up to 10.5%. Additionally, following the same methodology, the thermal behavior of these above-mentioned blocks but now with added internal insulation made of “recycled cellulose” was assessed, showing higher decreases up to 25.5%, increasing sustainability by addressing an additional reduction in waste, so the right combination of using by-products and the insulating filler in their cavities has been revealed as a promising way of optimizing the walls, offering a relevant improvement in energy savings. Finally, when comparing the U-values of the blocks made of concrete without insulation versus those made of by-products, with insulation, improvements up to 33.3% were reached. The adaptation of the procedure through a moisture correction factor was also incorporated.

This paper evaluates the indoor temperature and relative humidity of three construction systems in a Dominican social housing scheme, located in different micro-climates present in the Dominican Republic (DR). For the latter, we used DesignBuilder to model the most common type of social housing (S1). In addition, we have also modelled two other improved construction systems (S2 and S3), which have been the result of two different studies, which were conducted in DR. The simulations were carried out in 10 cities. These cities belong to the following five micro-climates: tropical wet Savanna, tropical wet rainforest, tropical wet jungle, dry semiarid and wet temperate. In this article, we have evaluated the construction systems’ performance in the context of thermal conditions inherent to DR. The latter has been done to verify which of the evaluated construction systems is the most adequate for each micro-climate. For this, we determined the average operating interior temperatures and relative humidities for each construction system. We conclude that Samples S2 and S3 show the lowest temperatures in warm climates, while Sample S1 shows improved performance in colder climates. S1 exhibits the lowest values of relative humidities, followed by S3, while S2 presents the highest values.
