A Study of Energy Simulation Integrated Process by Automated Extraction Module of the BIM Geometry Module

Abstract

Despite the international trend of actively utilizing BIM in the field of energy simulation, it is difficult to actively utilize BIM in domestic certification-related practice. As a result, the work process is not integrated and the work efficiency is reduced, such as the occurrence of redundant tasks. In this paper, the integrated process based on the BIM geometry information automated extraction module was presented and its effectiveness was reviewed and verified through self-developed automation module and uniformity and error-causing analysis. The construction of an integrated process through automatic configuration information extraction has the advantages of reducing the workload, enabling additional tasks through module function expansion, sharing information through the web, and ease of service manufacture. In addition, an experiment comparing the data of automatic and manual calculations with three subjects confirmed that automatic calculation database through automation module can produce a more reliable and uniform database with a lower proportion of human error than the manual calculation module. This not only improves the reliability of the energy simulation itself, but also reduces the human and temporal loads that occur during the post-simulation data verification process.

Sustainability and Energy Efficiency: BIM 6D. Study of the BIM Methodology Applied to Hospital Buildings. Value of Interior Lighting and Daylight in Energy Simulation

“…With this software, the energy model was also obtained, with which the energy simulation and analysis were subsequently performed with the plugin for REVIT, INSIGHT 360 [58]. This software performs energy simulation in the cloud, using industry-leading, trusted and widely established DOE 2.2 and EnergyPlus [59] simulation engines, DOE 2.2 [60] being the calculation engine of the Calener Unified Tool, a general option [61], to perform energy certifications for buildings in Spain. Once the energy simulation was carried out, the INSIGHT 360 platform visualized and interacted with the results obtained, through diagrams and performance diagrams directly in a virtual model, which allowed studying both the current state of the building, as well as possible energy improvements on the building [62,63].…”

Method for Building Information Modeling Supported Project Control of Nearly Zero-Energy Building Delivery

“…To do so, professionals in these phases must be encouraged to explore many variations concerning building orientation, relative compactness, window-to-wall ratio and positioning of windows, opaque elements construction (light, medium or heavy), preliminary U-values of opaque elements and windows, shadings, and g-value of windows. A professional who is controlling the NZEB project deployment should encourage the professionals in project delivery to use BIM in order to minimize information loss and errors as well as reducing the redundant tasks when observing designing/modeling the elements of building that impact the energy performance [28]. The other important reason for encouraging the BIM use is the possibility of using preliminary (black-box) building energy simulation tools that are implemented in BIM-authoring software (e.g., Archicad, Allplan, Revit).…”

“…The other approach is to extract data that is useful from BIM model which is than used for energy calculation that is based on standard which certain country adopted. Following this approach Choi et al [28] made a module in Python that extracts data from the IFC and they use this data for a calculation based on standard ISO 13790:2008. They declare this way more error-free when comparing it with manual input due to human error.…”

“…Similar research [29] shows how the information can be extracted and transferred from IFC to basis of semantic model that is then upgraded so it can calculate all the needed outputs to satisfy GB certificate in Singapore. The advantage of the approaches from [28,29] is controlled information extraction, so the information loss has minimized impact on energy calculation.…”

Applicability of Building Information Modelling (BIM) in the Sustainable Design of Commercial and Office Buildings. A Case Study from Tehran, Iran

“…In this regard, various studies have been carried out to overcome the existing barriers (Nemati et al, 2020;Kaneta et al, 2017). Also, a number of researchers are currently investigating the way of promoting BIM for real applications (Migilinskas et al, 2013;Kaneta et al, 2017), especially for energy consumption simulation purposes (Choi et al, 2019;Kamel and Memari, 2019;Pruvost and Scherer, 2017). The results of such studies have indicated that BIM can be efficiently used to reduce energy consumption and construction costs and to decrease the time of constructing a building.…”
