Models for control of thermal energy in buildings
Johansen, Casper Amandus; Lie, Bernt; Skeie, Nils-Olav (Peer reviewed; Journal article, 2019)A large fraction of the world’s energy production is used for HVAC in buildings. It is therefore important to develop improved strategies for ef?cient use of energy in buildings. Storage of intermittent energy production ... -
Object detection, information extraction and analysis of operator interface images using computer vision and machine learning
Illing, Eirik (Master thesis, 2023)Operator interface display images, often referred to as HMI, contains large amounts of information that can be valuable to obtain. If access to the source code or design files are limited, modern frameworks for object ... -
Parameter estimation for externally simulated thermal network models
Brastein, Ole Magnus; Lie, Bernt; Sharma, Roshan; Skeie, Nils-Olav (Peer reviewed; Journal article, 2019)Obtaining accurate dynamic models of building thermal behaviour requires a statistically solid foundation for estimating unknown parameters. This is especially important for thermal network grey-box models, since all their ... -
Parameter estimation for grey-box models of building thermal behaviour
Brastein, Ole Magnus; Perera, Degurunnehalage Wathsala U.; Pfeiffer, Carlos Fernando; Skeie, Nils-Olav (Journal article; Peer reviewed, 2018)Good models for building thermal behaviour are an important part of developing building energy management systems that are capable of reducing energy consumption for space heating through model predictive control. A popular ... -
Selection methodology of energy consumption model based on data envelopment analysis.
Nakhodov, Vladimir; Baskys, Algirdas; Skeie, Nils-Olav; Pfeiffer, Carlos Fernando; Dmytro, Ivanko (Journal article; Peer reviewed, 2017)The energy efficiency monitoring methods in industry are based on statistical modeling of energy consumption. In the present paper, the widely used method of energy efficiency monitoring “Monitoring and Targeting systems” ... -
Sensor placement and parameter identifiability in grey-box models of building thermal behaviour
Brastein, Ole Magnus; Sharma, Roshan; Skeie, Nils-Olav (Journal article; Peer reviewed, 2019)Building energy management systems can reduce energy consumption for space heating in existing buildings, by utilising Model Predictive Control. In such applications, good models of building thermal behaviour is important. ... -
Short-Term Solar and Wind Power Generation Prediction
Mollasalehi, Afsaneh (Master thesis, 2023)The increasing global population has raised concerns about the sustainability of energy supply. Renewable energy sources like solar and wind power have garnered significant attention due to their environmental benefits. ... -
Structural observability analysis and EKF based parameter estimation of building heating models
Perera, Degurunnehalage Wathsala U.; Perera, M. Anushka S.; Pfeiffer, Carlos Fernando; Skeie, Nils-Olav (Journal article; Peer reviewed, 2016)Research for enhanced energy-efficient buildings has been given much recognition in the recent years owing to their high energy consumptions. Increasing energy needs can be precisely controlled by practicing advanced ... -
