Green BIM-based building energy performance analysis

Abstract

Today, automotive design has to face numerous exciting challenges. The growing globalization causes an intensified competition amongst car manufacturers and forces them to reduce the required development time in order to shorten time to market, to appear first with attractive new products. Efficient and flexible processes and tools are necessary to handle the arising complexity efficiently. Parametric-associative 3D-CAD systems offer ideal conditions to face this challenge in virtual development. The present paper focusses on a special issue in automotive concept phasethe vehicle architecture layout process and required parameterization strategies. In most cases, parametric-associative relations defined within 3D-CAD models are of rigid kind. This implies that a formula, which is defined within a 3D-CAD model in order to evaluate a specific parameter, cannot change the input/output situation of involved parameters. In most application cases, this disadvantage can be neglected, but not in case of vehicle layouting in the early concept phase. Since geometric boundary conditions which define the geometric base of a vehicle concept can vary significantly, a rigid model parameterization is not the proper solution and prevents efficient reuse of 3D-CAD models. Additionally, rigid parameterization concepts lack of the required flexibility when having to manage multiple design variants in a single model. Therefore, the present paper outlines a possible strategy, which enables the use of advantages of parametric-associative design, while allowing changes of relations-evaluation behavior in context of respective technical issues and simultaneously preserving necessary geometrical model consistency.

Building Information Modeling (BIM) Capabilities in the Operation and Maintenance Phase of Green Buildings: A Systematic Review

“…around green buildings can also be captured [74,123,124]. BIM can also be connected to the Internet of Things (IoT) to search for and retrieve weather-related information [75].…”

“…According to the literature review of Section 3, the BIM simulation influences the aspects of safety and emergency management, energy management, retrofit and renovation, and space management. From the perspective of energy management, the light, heat, radiation, ventilation, temperature, humidity, and terrain of the indoor and surrounding environment can be simulated through BIM utilization, thus speculating the energy consumption based on this information [75,76,78,[81][82][83]91]. In this process, by integrating the indoor and surrounding environment, building-related characteristics (location, material, orientation, etc.…”

“…To fully consider the climate and weather factors in the energy management process in green buildings, C.-J. Chen et al [75] developed virtual weather station technology utilizing BIM cloud tools; it facilitated green building to obtain and retrieve simulated weather-related data from the nearest weather stations. Subsequently, the collected data were transmitted to DOE-2 Engine in gbXML format to support energy performance analysis.…”

Application of Mathematical Methods Based on Improved Fuzzy Computing in Building and Urban Design in the Environment of Industry 4.0

“…In this way, when the building is enlarged into a system, the details of the near-human scale are at its most microscopic level. However, the building volume observed from the city's perspective becomes its macro scale, and it is observed from the perspective of the street, that is, urban design [ 3 ].…”

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

“…While BIM tolerates performance assessment at earlier building stages, such as orientation, the location of material properties, and window to wall ratio (Chen et al, 2017;Gao et al, 2019), BEM software tools professionally evaluate building performance in more advanced stages (Jin et al, 2019). Accordingly, coupling the two models can reduce the effort and time consumed in generating model geometry and, by assigning building parameters in the BIM-based BEM model, the data exchange and information reliability can be maintained (Chen et al, 2018).…”
