Application of the proposed method is demonstrated using two cases studies: (1) a TRNSYS model of a water-cooled chiller in a mixed-use building in Singapore, and (2) an EnergyPlus model of the cooling system of an office building in Pennsylvania, U.S.A.

A Bayesian approach for predicting building cooling and heating consumption 2013. Multiobjective optimization of building design using TRNSYS simulations, genetic algorithm. The calibrated model was assessed by evaluating both accuracy and convergence. Modelica-enabled rapid prototyping via TRNSYS 2013 English. Tiao, Bayesian Inference in Statistical Analysis, 2011. This is achieved by: (1) using information theory to select a representative subset of the entire dataset for the calibration, and (2) using a more effective Markov chain Monte Carlo (MCMC) algorithm, the No-U-Turn Sampler (NUTS), which is an extension of Hamiltonian Monte Carlo (HMC) to explore the posterior distribution. This study focuses on improvements to the current implementation of Bayesian calibration to building energy simulation. However, its application has been limited to calibration using monthly aggregated data because it is computationally inefficient when the dataset is large. īayesian calibration as proposed by Kennedy and O'Hagan has been increasingly applied to building energy models due to its ability to account for the discrepancy between observed values and model predictions. Bayesian calibration of building energy models with large datasets. LSTM models achieved a low Mean Absolute Error of 0.55 C and the lowest Root Mean Square Error scores (1.27 C) for temperature sequence predictions, as well as the lowest variance (0.520 C2 ) and relative prediction errors (3.Bayesian calibration of building energy models with large datasetsĬhong, Adrian, Lam, Khee Poh, Pozzi, Matteo, Yang, Junjing (). Although similar results are achieved with the tested architectures, both RNN and LSTM outperform ANN when replicating the data's temporal behavior all of which outperform naïve pre-dictors and other regression models such as Bayesian Ridge, Gaussian Process and Linear Regression.

#BAYESIAN TRNSYS SOFTWARE#
A physical simulation model is developed in TRNSYS software to generate large quantities of synthetic operational data in nominal conditions. Techniques such as artificial neural networks (ANN) recurrent neural networks (RNN) and long short-term memory (LSTM) are explored. In the present work, Deep Learning models are trained to predict the performance of an SHW system under different meteorological conditions. Recently, data-driven techniques have been successfully used for Prognosis and Health Management applications. As solar energy is a variable resource, performance prediction methods are useful tools to increase the overall availability and effective use of these systems. Solar Hot Water (SHW) systems are a sustainable and renewable alternative for domestic and low- temperature industrial applications.
