Building Information Modeling-Based Building Energy Modeling: Investigation of Interoperability and Simulation Results

Abstract

There is increasing need to apply building information modeling (BIM) to low energy buildings, this includes building energy modeling (BEM). If a building energy model can be flawlessly generated from a BIM model, the energy simulation process can be better integrated within the design, can be more competent, and timesaving. However, concerns about both the reliability and integrity of the data transfer process and the interoperability between the BIM and BEM prevent any implementation of BIM-based energy modeling on a large scale. This study addresses the accuracy and integrity of BIM-based energy modeling by investigating how well Autodesk's Revit (BIM), in conjunction with two of the most used energy modeling programs (BEM) known as DesignBuilder and Virtual Environment (IES-ve), were integrated in terms of interoperability, including location and weather files, geometry, construction and materials, thermal zones, occupancy operating schedules, and HVAC systems. All misrepresented data during the interoperability process were identified, followed by benchmarking between the BIM-based energy modeling simulation outcomes and the actual energy consumption of the case study, to assess the reliability of the process. The investigation has revealed a number of interoperability issues regarding the BIM data input and BEM data interpretation. Overall, BIM-based energy modeling proved to be a promising tool for sustainable and low energy building design, however, the BIM to BEM process is a non-standardized method of producing building energy models as it varies from one modeler to another, and the BIM to BEM process. All these might slow down any possible application for the process and might cause some uncertainties for the professionals in the field applying it.

Improving the Efficiency of Maritime Infrastructures through a BIM-Based Building Energy Modelling Approach: A Case Study in Naples, Italy

“…As said, BEM has experienced significant growth in recent years [14]. Its application within the construction industry by architects and engineers allows building energy consumption reduction by supporting informed choices of effective low energy-consuming strategies [15,16].…”

Evaluating the Impact of Energy Efficiency Building Codes for Residential Buildings in the GCC

“…Several studies have analysed the use of simulation tools in evaluating the energy and thermal performance of buildings [45,46]. According to a comprehensive review based on the most used building energy modelling tools, DesignBuilder, developed by DesignBuilder Software Ltd in the UK, is the most suitable tool for assessing performance applications and criteria [47][48][49]. It is the most comprehensive interface for the well-known EnergyPlus, (which is Department of Energy's open-source whole-building energy modeling (BEM) engine), compared to others [50].…”

DesignBuilder outcomes have been validated and used in several studies with similar aims to the current study [49,51].…”

A methodology for generating a synthetic local urban climate weather profile for building energy simulations in hot arid areas

“…In line with the study objective in assessing the outdoor microclimate condition on the building energy performance, the new microclimate weather data extracted from previous phases was then used as an input in the building energy modelling program (BEM) to calculate the energy consumption for the examined building. The Integrated Environmental Solution's Virtual Environment (IESVE, 2011) is an industry standard and validated software, its analysis includes thermal and comfort analysis, daylighting, solar studies, egression, and carbon emissions code compliance (Azhar and Brown 2009;Annan et al 2014;Elnabawi 2020).…”

“…The aim of the study is to examine the validity of modelling approach and coupling procedure. Therefore, the accuracy of the energy simulation is determined by the ability of the input data to accurately represent the case study (Elnabawi 2020), as it represents the complex reality without simplification (Blocken et al, 2012). Therefore, two different weather profiles were used to simulate the same energy model using IESVE, as per the European Standard EN 15603 (DS/EN, 2008) validation procedures (std.…”
