      Article
      Open Access
      This study aims to picture the phenomenology of urban ambient total lung deposited surface area (LDSA) (including head/throat (HA), tracheobronchial (TB), and alveolar (ALV) regions) based on multiple path particle dosimetry ...

    • Analyzing the implementation of predictive control systems and application of stored data in non-residential buildings 

      Savadkoohi, Marjan; Macarulla Martí, Marcel; Tejedor Herrán, Blanca; Casals Casanova, Miquel (2024-08-22)
      Article
      Open Access
      In non-residential buildings, building energy management systems (BEMS) and the application of data hold significant promise in reducing energy consumption. Nevertheless, BEMS have different levels of complexity, benefit, ...

    • Assessing the performance of the neural network-based control to manage boilers through a reduced-order building's model 

      Savadkoohi, Marjan; Macarulla Martí, Marcel; Casals Casanova, Miquel (Asociación Española de Ingeniería de Proyectos (AEIPRO), 2022)
      Conference report
      Open Access
      There is a growing need to optimize the heating ventilation and air conditioning (HVAC) systems during building operations due to its high contribution to buildings' energy consumption and the willingness to meet the ...

    • Constructing transferable and interpretable machine learning models for black carbon concentrations 

      Fung, Pak Lun; Savadkoohi, Marjan; Zaidan, Martha Arbayani; Niemi, Jarkko V.; Timonen, Hilkka; Pandolfi, Marco; Alastuey, Andres; Querol Carceller, Xavier; Hussein, Tareq; Petaja, Tuukka (Elsevier, 2024-02-01)
      Article
      Open Access
      Black carbon (BC) has received increasing attention from researchers due to its adverse health effects. However, in-situ BC measurements are often not included as a regulated variable in air quality monitoring networks. ...

    • Facilitating the implementation of neural network-based predictive control to optimize building heating operation 

      Savadkoohi, Marjan; Macarulla Martí, Marcel; Casals Casanova, Miquel (Elsevier, 2023-01-15)
      Article
      Open Access
      Simple neural network (NN) architecture is a reliable tool to transform reactive rule-based systems into predictive systems. Thermal comfort is of utmost importance in office buildings, which need the activation of heating ...
