Análise comparativa entre edificações de energia zero certificadas pela GBC Brasil e pelo Departamento de Energia dos EUA (DOE)

Abstract

With the growth in the consumption of electricity in buildings, some countries have adopted policies to encourage the implementation of Zero Energy Buildings, which are projects with a high energy efficiency index and generation of electricity with renewable sources to compensate for energy consumption. electrical. In Brazil, there are still no policies for the implementation of Zero Energy Buildings, so the work analyzes the method used by GBC Brasil's Zero Energy certification and compares it with the method adopted by the US Department of Energy (DOE). The analysis is based on comparing the calculation of source energy, which consists of calculating the energy balance between consumption and generation of electricity, the rules adopted regarding the use of Renewable Energy Certificates (REC) are also evaluated, definitions regarding energy efficiency measures, in addition to the evaluation of energy performance through the Area Energy Use Index (AEUI), Energy Use Index by Area, which verifies the building's consumption in kWh / year by area (m²). The study will be applied in the buildings of SECONCI, Paola & Panasolo, Petinelli, Lar Verde Lar and Polo Shirts Salvador that have the Zero Energy certification from GBC Brasil. Camisa Polo Salvador is the only building in the Northeast region, serving as a reference and case study for other buildings that wish to acquire Zero Energy certification. It is concluded that only Paola & Panasolo, is not categorized as ZEB, Zero Energy Building, according to the DOE, by using REC, which are certificates used to complement the generation of the building and promote the zero energy balance. By calculating the AEUI, it is verified that the Zero Energy projects that have the best performance in energy efficiency are Seconci and Lar Verde Lar.
