BIM-based Parametric Building Energy Performance Multi-Objective Optimization

Abstract

Building energy performance assessments are complex multi-criteria problems. Appropriate tools that can help designers explore design alternatives and assess the energy performance for choosing the most appropriate alternative are in high demand. In this paper, we present a newly developed integrated parametric Building Information Modeling (BIM)-based system to interact with cloud-based whole building energy performance simulation and daylighting tools to optimize building energy performance using a Multi-Objective Optimization (MOO) algorithm. This system enables designers to explore design alternatives using a visual programming interface, while assessing the energy performance of the design models to search for the most appropriate design. A case study of minimizing the energy use while maximizing the appropriate daylighting level of a residential building is provided to showcase the utility of the system and its workflow.

WP-BIM: Web-based Parametric BIM Towards Online Collaborative Design and Optimization

“…classical calculus for solving optimization problems that can be formulated as continuous and differentiable equations, linear programming for problems that can be modeled by linear relationships between variables, and dynamic programming for those with discrete and stochastic variables. In addition, different Genetic Algorithm tools, including BIM-and visual programming-based Optimo (Rahmani Asl et al 2014Asl et al , 2015aAsl et al , and 2015b) can be included in the framework. It is expected that the Web-based, collaborative parametric design method utilizing different modeling and visual programming tools will enhance the multi-disciplinary and multiobjective design optimization process for architecture.…”

Sustainable Consumption Patterns Adopting BIM-Enabled Energy Optimization - A Case Study of Developing Urban Centre

“…According to Asl, Bergin [20], the energy modeling tools currently used for simulating buildings lack their support to establish parametric relations with the building objects. Besides many other various parameters for energy consumption for buildings, the orientation is an important parameter to achieve energy efficient design [21,22].…”

Structural Grid Predesign using Generative Design for Residential Building with Steel Structure on BIM Models - Structural grid predesign using generative design

“…Optimisation problems have been carried out in several areas, from aerospace engineering to architectural design (Hahn et al, 2010;Holst et al, 2013;Asl et al, 2014). Multi-objective optimisation can use a genetic algorithm to allow automated algorithmic processes to generate, evaluate, and improve possible design options' performance.…”
