Affordable housing and clean technology transfer in construction firms in Brazil

The affordable housing deficit in Brazil is 5.6 million homes. The Main Brazilian housing government program was called “Minha Casa, Minha Vida” from 2009 to 2020. It had little progress in the housing sustainability requirements in the last ten years. For that reason, construction industry has very little changed in terms of innovation. However, this sector has maintained standard production on a large scale. So, the crucial change could become from companies. The clean technology transfer is limited in the Brazilian affordable housing firms. One solution is to analyse this transfer process like a network. Then, it will be possible to evaluate the technological adaptability of these kinds of construction firms. This research aimed to estimate the clean technology transfer between construction firms in Brazil dedicated to building affordable housing. For this, it was identified the 69 construction firms in five cities of Rio Grande do Sul. The cities were Canoas, Caxias do Sul, Passo Fundo, Pelotas, Porto Alegre. Then, a network analysis identified the degree, betweenness, closeness, and density. These studies identify poor performance versus sustainability needs of current low-cost construction. As a result, it identifies the technology transfer capabilities that allow medium-term gains for Brazilian construction firms. Finally, we developed technology transfer indicators to understand the complexity of affordable housing production in Brazil.
