  1. 1. Demand controlled ventilation : Impact on energy use and indoor environmental quality

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Therese Ottosson; [2023]
    Keywords : ;

    Abstract : European buildings account for a significant share of the energy-related emissions in Europe. Addressing the increasing energy use and its contribution to greenhouse gases (GHG) is internationally recognized as crucial, and emissions must be halted. READ MORE

  3. 2. Understanding the Building Processes of a Net-Zero Energy Building : A follow-up study on an energy effective campus building and interactions between the occupants and the smart HVAC system

    University essay from KTH/Hållbara byggnader

    Author : Ajaysingh Patil; [2023]
    Keywords : ;

    Abstract : Net-Zero Energy Buildings (NZEBs) have emerged as a result of rapid advancements in the construction industry and the growing demand forsustainable buildings. However, this progress has led to a potential gap in information dissemination between policy makers and buildingprofessionals. READ MORE

  4. 3. Predicting room occupancy based on carbon dioxide concentration levels : And potential energy-saving use cases in HVAC (heating, ventilation and air conditioning) control systems.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elias Eliasson Schuhmacher; Markus Ledung; [2023]
    Keywords : ;

    Abstract : This thesis aims to explore the possibilities of recording room occupancy based on measured CO2 (carbon dioxide) concentration levels, and potential energy-saving uses in HVAC (heating, ventilation and air conditioning) - control systems. Furthermore, this thesis specifically aims to use unsupervised machine learning methods, which removes the need for generating correct occupancy labels and training the models before deploying them.

  5. 4. Physics-Enhanced Machine Learning for Energy Systems

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Lindström; Emil Sundström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Building operations account for a large amount of energy usage and the HVAC (Heating, Ventilation and Air Conditioning) systems are the largest consumer of energy in this sector. To reduce this demand, more energy-efficient control algorithms are implemented and a popular choice for a controller is the model predictive control. READ MORE

  6. 5. FAULT DETECTION IN AIR HANDLING UNIT (AHU) USING MACHINE LEARNING

    University essay from Högskolan Dalarna/Mikrodataanalys

    Author : Humphry Takang Bate; Wilkingson Igbinosun; [2022]
    Keywords : Fault Detection; AHU; Machine Learning;

    Abstract : Fault in Air Handling Unit (AHU) of the Heating, Ventilation, and Air Conditioning (HVAC) systems in buildings is a challenge that building managements face. These faults cause buildings to waste 15 – 30% of the energy consumed by the AHU. READ MORE
