Containers have been widely used as buildings lately; therefore, they need to meet thermal performance requirements by using, depending on the climate, insulation materials, and additional layers for the enclosure. This study compares the environmental performance of a container building for commercial use with different constructive strategies for the envelope. The methodology was based: (a) definition of the envelope constructive alternatives for the container building; (b) thermal and energy performance simulations with the aid of DesignBuilder software for four cities in different Brazilian bioclimatic zones (ZB): São Paulo (ZB2), Brasilia (ZB4), Teresina (ZB7) and Rio de Janeiro (ZB8); (c) Life Cycle Assessment (LCA), from cradle to grave, considering the following categories of damage: (1) Climate Change, (2) Human Health, (3) Ecosystem Quality and (4) Depletion of Resources. The envelope constructive alternative of drywall and thermal insulation was more advantageous than the others. The thermal absorptance influenced the results, especially for ZB7 and ZB8. The city of Teresina showed the highest operational energy consumption and, consequently, the highest environmental impact. Moreover, environmental guidelines were presented for this type of building.
