• Carbon dioxide-based occupancy estimation using stochastic differential equations 

      Wolf, Sebastian; Cali, Davide; Krogstie, John; Madsen, Henrik (Peer reviewed; Journal article, 2019)
      In the existing building stock, heating, cooling and ventilation usually run on fixed schedules, in many cases, even all day. In particular, ventilation systems often run with a constant air flow rate that is adjusted based ...
    • climify.org: an online solution for easy control and monitoring of the indoor environment 

      Cali, Davide; Kindler, Ekkart; Ebrahimy, Razgar; Bacher, Peder; Hu, Kevin; Østrup, Michelle Lind; Bachalarz, Magnus; Madsen, Henrik (Journal article; Peer reviewed, 2019)
      Real energy performance of new and retrofitted buildings often consistently differs from expectations. While occupants might complain about poor indoor climate, the energy use in such buildings is often higher than expected, ...
    • 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 ...
    • 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 ...
