Methods for Assessing Energy Efficiency of Buildings

Abstract

This article analyzes the case of a Brazilian Institute of Higher Education, in relation to compliance with a normative instruction, according to which all federal public buildings must follow the rules of energy efficiency. The aim of this work is to demonstrate the potential of Building Information Modeling to optimize the execution of reference instructions. As a case study, the energy efficiency of one of the Institute buildings was observed using the conventional method and a new method. Subsequently, a comparative analysis was carried out to indicate the most appropriate procedure for the Institute. Finally, it was observed that the new method showed an approximately 85% reduction in classification time due to its better performance in obtaining architectural design information and, if incorporated in the routine of the project, will contribute more adequately to the interests of the Institute.

Design Optimization of Energy Efficient Residential Buildings in Mediterranean Region

“…The optimal cost point is achieved by introducing an artificial light control system only to the base reference building. Serra and Filho demonstrate the potential of Building Information Modeling to optimize the execution of reference instructions [23]. The new method showed an approximately 85% reduction in classification time.…”

Using BIM to improve building energy efficiency – A scientometric and systematic review

“…So far, as a ''proof of concept" [76], BIM models can store all of this information, apart from user behaviour, which lacks research [81,99,104] but, as shown by Baldi et al [227], occupant-building interaction can be automated and help improve overall building performance, opening the door to BIM integration. Moreover, BIM can act as a basis for energy analysis software to estimate a building's energy needs [36,175,194,202]. Regarding equipment, especially related with renewable energy, BIM tools are not yet capable of modelling all of the existing solutions on this front [105,111].…”

Experimental determination of the air exchange system influence on the thermal conditions of a local working area heated by a gas infrared heater

“…The issues of energy efficiency of residential and industrial buildings are becoming increasingly relevant [1][2][3][4][5]. There are various ways to improve the energy efficiency of buildings, for example, changing the building thermal envelope, or improving the heating system [6,7].…”
