Optimizing Energy Efficiency in Operating Built Environment Assets through Building Information Modeling: A Case Study

Abstract

Abstract:Reducing carbon emissions and addressing environmental policies in the construction domain has been intensively explored with solutions ranging from energy efficiency techniques with building informatics to user behavior modelling and monitoring. Such strategies have managed to improve current practices in managing buildings, however decarbonizing the built environment and reducing the energy performance gap remains a complex undertaking that requires more comprehensive and sustainable solutions. In this context, building information modelling (BIM), can help the sustainability agenda as the digitalization of product and process information provides a unique opportunity to optimize energy-efficiency-related decisions across the entire lifecycle and supply chain. BIM is foreseen as a means to waste and emissions reduction, performance gap minimization, in-use energy enhancements, and total lifecycle assessment. It also targets the whole supply chain related to design, construction, as well as management and use of facilities, at the different qualifications levels (including blue-collar workers). In this paper, we present how building information modelling can be utilized to address energy efficiency in buildings in the operation phase, greatly contributing to achieving carbon emissions targets. In this paper, we provide two main contributions: (i) we present a BIM-oriented methodology for supporting building energy optimization, based on which we identify few training directions with regards to BIM, and (ii) we provide an application use case as identified in the European research project "Sporte2" to demonstrate the advantages of BIM in energy efficiency with respect to several energy metrics.

Review and Mapping of Parameters for the Early Stage Design of Adaptive Building Technologies through Life Cycle Assessment Tools

“…Experts and research communities need to solve issues related to inconsistency, transparency, comparability, availability and quality of the collected data [33]. Among the tools that are expected to improve the acquisition of necessary building data in the early design stages, Building Information Modelling (BIM) is considered as an effective platform, which would also allow to codify specific design parameters of an LCA context [76,117]. More specifically, EPD data could be integrated into BIM design files to reduce time-consumption and improve data quality in the early design phase [33].…”

Analysis of the Operation of an Aerothermal Heat Pump in a Residential Building Using Building Information Modelling

“…The result of this practice is expected to be the design of more efficient buildings through evaluation of different design options [14]. The interface that provides the exchange of information between BIM and the energy efficiency simulation tool is of the utmost importance to facilitate the task of the professionals involved in the building design [15].In Europe, efficient aerothermal heat pumps are being strongly promoted in domestic applications for substituting gas boilers. In fact, the main HVAC manufacturers are already offering a variety of these systems targeted to the residential sector.…”
