Sustainable design protocol in BIM environments: case study of 3D virtual models of a building in Seville (Spain) based on BREEAM method

Abstract

One of the key problems facing the construction industry concerns the requirement to integrate sustainability criteria that effectively reduce the environmental impact throughout the lifecycles of buildings. For this, it is necessary to use digital tools with the capacity to evaluate the environmental performance of the different solutions proposed through the design process. In this context, the objective of this study was to establish a protocol of sustainable standards defined by the Building Research Establishment Environmental Assessment Method (BREEAM), employing building information modeling (BIM) technology to simplify the integration of these indicators in the initial phases of the design process. This study focuses on a case study associated with the use of BIM technology and the BREEAM method. The results of the analysis enable us to define which of the BREEAM indicators can be integrated into and evaluated in BIM environments in the initial phase of the design process and to identify the environmental improvements and economic costs associated with these indicators. This study concludes that the indicators associated with the geometric and spatial definition of the building are the most influential in improving sustainability in the initial design phase, without requiring significant economic investment. In turn, these are easy parameters to evaluate using BIM, reducing design times compared to the use of traditional tools; this facilitates their involvement in the design phase and enables them to have a real impact on improving the environmental conditions of the final construction.
