First steps towards low energy buildings: how far are Chilean dwellings from nearly zero-energy performances?

In Chile, the nearly zero-energy goal for new dwellings is scheduled by 2035. Recently, a draft regulation was published, highly tightening the energy-environmental requirements within the building regulations. This study uses dynamic thermal simulations to evaluate the energy performance of new Chilean dwellings and the impact these new requirements would produce along the country's climatic differences. In addition, strategies addressing the remaining causes of energy loss are proposed, in an attempt to approach Chilean dwellings to nearly zero-energy performances.
