Machine Learning for Benchmarking Models of Heating Energy Demand of Houses in Northern Canada

Abstract: In most cases, the benchmarking models of energy use in houses are developed based on current and past data, and they continue to be used without any update. This paper proposes the method of retraining of benchmarking models by applying machine learning techniques when new measurements are made available. The method uses as a case study the measurements of heating energy demand from two semi-detached houses of Northern Canada. The results of the prediction of heating energy demand using static or augmented wi… Show more

“…The ASHRAE Standards indicate that at the hourly resolution a CV(RMSE) of 30% is considered calibrated for a building [24] and a consensus between researchers applying the ASHRAE standards to HVAC modeling specifically has determined that a daily CV(RMSE) under 35% is acceptable [25]. The HVAC load predictions obtained with the proposed LSTM model using the "perfect" weather forecast are well within these limits.…”

“…The PCA method, which is commonly used for dimension reduction and feature extraction [61,62], was applied using experimental data by [63,64] for single and multiple FDD in chillers and space heating and domestic hot water systems. Hybrid PCA models were applied for MFDD by [65][66][67][68].…”
