Resumo
[Abstract] Nowadays, European Union (EU) requests that all its members encourage Net-zero energy and emission in the
buildings by 2050. There are multiple studies within the EU related to this field, but few of them are associated
with environmental cost assessment and reduction. What can be the new strategies allowing to reduce ecological
impact costs at the scale of the building? In response to this question, this research has been carried out, with, the
main objective, to evaluate, analyse, and propose some scenarios allowing to design of residential buildings with
nearly zero energy, low emission, and low cost throughout the world. The strategies detailed in this research can
be applied and adapted in all the regions of the world. A life cycle assessment (LCA) of a typical building is
carried out using the Pleiades software database comprising a Dynamic Thermal Simulation calculation engine
(STD) making it possible to simulate the thermal in order to describe the energy behaviours of a building and its
equipment. Four life cycle phases (construction, use, renovation, and end of life) of buildings have been assessed.
The results showed that the use of a dual-service air-to-water heat pump enables a considerable reduction in
greenhouse gas (GHG) emissions and, on average, the indicators decrease by around 9%. It was concluded that
the use of heat pumps makes it possible to reduce the cost of 9 environmental impacts between 8.7% and 13.1%
compared to the initial cost, over a period of 80 yr.
