Abstract

Climatic zoning for building energy efficiency purposes is an important element in building energy policy; however, there is no consensus about the most appropriate methodology for its definition. Nowadays, more than 54 countries are subject of climatic zoning and in most of the cases few parameters are taken into account. Currently, there are no procedures or performance indicators to assess the validity of a proposed climatic zoning, hindering the decision to use a particular climatic zoning methodology instead of another. This scenario put at risk the effectiveness of building energy policies and programs based on climatic zoning. In this context, this project presents a novel approach, consisting on intensive use of archetypes, building performance simulation and geographic information system to facilitate the validation of climatic zoning. This procedure is based on the principle that two areas should belong to the same climatic zoning if building performances are similar in both areas, considering a set of archetype buildings. The validation procedure will be applied to a case study in the State of Sao Paulo through the validation of two climatic zoning methodologies: the Brazilian climatic zoning of the Standard NBR-15220 and the second proposition of Brazilian climatic zoning developed by ANTAC. The number of comfort hours of residential archetypes based on the adaptive comfort model will be used as performance indicator. Simulations will be conducted using the Energy Plus program. Pre-processing and post-processing of data will be fully automated with MatlabR14 routines. GIS programs will be used in the validation process. Results of this research will furnish a method capable to provide an impartial comparison between climatic zoning results obtained using different methodologies and eventually choose the one with the best performance.
