Abstract

MICHAUX, Celina; VIEGAS, Graciela Melisa  and  BLASCO LUCAS, Irene. International regulations on building energy efficiency: comparative analysis of architectural envelope evaluations. An. Investig. Arquit. [online]. 2023, vol.13, n.1, e203.  Epub June 01, 2023. ISSN 2301-1505.  https://doi.org/10.18861/ania.2023.13.1.3369.

The elements that make up the architectural envelope in contact with the outside represent a conclusive factor in energy consumption and have a direct influence on the energy demand of the building. For this reason, the objective of the work is to analyze the different ways of energetically evaluating the architectural envelope in regulations at a global level and detecting its representative components. The research methodology is a theoretical-descriptive study, based on a systematic mapping that enables comparison between regulations. Next, the analysis variables and the type of information contained in them are obtained. It follows that the most important aspects to consider in the design and evaluation of the envelope are the climatic zone present in 34% of the regulations, the glaze-opaque relationship, and the thermal transmittance, present in 41% and 93% respectively. When comparing the scope of Argentine regulations with international examples, it is concluded that it is necessary to reinforce the studies and regulations related to the glaze-opaque relationship.
