Significant action is needed across the Chilean housing sector to reduce energy consumption and meet climate change mitigation goals.

Abstract

Significant action is needed across the Chilean housing sector to reduce energy consumption and meet climate change mitigation goals. In this study, the performance of a typical house, an optimised house and a Passivhaus in various climates is evaluated and compared, considering eight distinct climatic zones of Chile. For the thermal optimisation of the house, an OpenBIM workflow between REVIT-CYPETHERM and EnergyPlus with JEPlus were interfaced to analyse over a thousand possible combinations of energy optimisation measures for each climate zone. Additionally, a Life Cycle Assessment is used to compare the cases studied. The results show that in the manufacturing stage, building a Passivhaus would have greater environmental impacts than a traditional house. Additionally, it is shown that in warm climatic zones, a thermally optimised house can have an energy performance equivalent to housing constructed to Passivhaus standards but with less environmental impacts in all its phases of the life cycle.
