Detailed parametric analysis and measurements are required to reduce building energy usage while maintaining acceptable thermal conditions. This research suggested a system that combines Building Information Modeling (BIM), machine learning, the non-dominated sorting genetic algorithm-II (NSGA II) investigate impact of factors on find optimal design. A plugin is developed receive sensor data export all necessary information from BIM MSSQL Excel. The model was imported IDA Indoor Climate Energy (IDA ICE) execute an consumption simulation then pairwise test produce sample set. To study set develop prediction between usage, 11 learning algorithms used. best algorithm Group Least Square Support Vector Machine (GLSSVM), later employed in NSGA II as fitness function using Dynamo software. An multi-objective optimization designed optimize interior comfort (measured by predicted percentage dissatisfied (PPD)). Pareto front calculated, optimum point approach used combination envelope characteristics, HVAC setpoints, shading parameters, lighting, air infiltration. feasibility effectiveness framework demonstrated case upper secondary school Norway; results show that: (1) GLSSVM has unique capacity forecast use with high accuracy: R2 0.99, RMSE 1.2, MSE 1.44, MAE 0.89; (2) may be successfully improved GLSSVM-NSGA hybrid technique, which reduces 37.5% increases 33.5%, respectively.

Digital Twin of HVAC system (HVACDT) for multiobjective optimization of energy consumption and thermal comfort based on BIM framework with ANN-MOGA

Advances in Building Energy Research, Journal Year: 2022, Volume and Issue: 17(2), P. 125 - 171

Published: Oct. 26, 2022

This study proposes a novel Digital Twin framework of heating, ventilation, and air conditioning (HVACDT) system to reduce energy consumption while increasing thermal comfort. The is developed help the facility managers better understand building operation enhance HVAC function. based on Building Information Modelling (BIM) combined with newly created plug-in receive real-time sensor data as well comfort optimization process through Matlab programming. In order determine if suggested practical, were collected from Norwegian office between August 2019 October 2021 used test framework. An artificial neural network (ANN) in Simulink model multiobjective genetic algorithm (MOGA) are then improve system. comprised distributors, cooling units, heating pressure regulators, valves, gates, fans, among other components. this context, several characteristics, such temperatures, pressure, airflow, control, factors considered decision variables. objective functions, predicted percentage dissatisfied (PPD) usage both calculated. As result, ANN's variables function correlated well. Furthermore, MOGA presents different design that can be obtain best possible solution terms usage. results show average savings for four days summer roughly 13.2%, 10.8% three months (June, July, August), keeping PPD under 10%. Finally, compared traditional approaches, HVACDT displays higher level automation management.
