    • CO2-based grey-box model to estimate airflow rate and room occupancy 

      Wolf, Sebastian; Alonso, Maria Justo; Cali, Davide; Krogstie, John; Mathisen, Hans Martin; Madsen, Henrik (Journal article; Peer reviewed, 2019)
      In the existing building stock, heating, cooling and ventilation often run on fixed schedules assuming maximal occupancy. However, fitting the control of the HVAC system to the building’s real demand offers large potential ...

    • Evaluation Method for the Hourly Average CO2eq. Intensity of the Electricity Mix and Its Application to the Demand Response of Residential Heating 

      Clauß, John; Stinner, Sebastian; Solli, Christian; Lindberg, Karen Byskov; Madsen, Henrik; Georges, Laurent (Journal article; Peer reviewed, 2019)
      This work introduces a generic methodology to determine the hourly average CO2eq. intensity of the electricity mix of a bidding zone. The proposed method is based on the logic of input–output models and avails the balance ...

    • Evaluation of low-cost formaldehyde sensors calibration 

      Justo Alonso, Maria; Madsen, Henrik; Liu, Peng; Jørgensen, Rikke Bramming; Jørgensen, Thomas Berg; Christiansen, Even Johan; Myrvang, Olav Aleksander; Bastien, Diane; Mathisen, Hans Martin (Peer reviewed; Journal article, 2022)
      Low-cost sensors (LCS) are becoming ubiquitous in the market; however, calibration is needed before reliable use. An evaluation of the calibration of eight identical pre-calibrated formaldehyde LCS is presented here. The ...

    • A methodology for the selection of pollutants for ensuring good indoor air quality using the de-trended cross-correlation function 

      Justo Alonso, Maria; Wolf, Sebastian; Jørgensen, Rikke Bramming; Madsen, Henrik; Mathisen, Hans Martin (Peer reviewed; Journal article, 2021)
      CO2 is customarily used to control ventilation as it is a proxy for bio-effluents and pollutants related to the presence and activity of people in the room. However, CO2 could not be a satisfactory indicator for pollutants ...

    • Room-level occupancy simulation model for private households 

      Wolf, Sebastian; Cali, Davide; Alonso, Maria Justo; Li, Rongling; Korsholm Andersen, Rune; Krogstie, John; Madsen, Henrik (Journal article; Peer reviewed, 2019)
      This work presents a novel occupancy simulation model for residential buildings. The main contribution is that occupancy is simulated at room level, as opposed to more course spatial resolutions in previous studies. The ...
