  1. 1. Parametric Analysis of Thermal Comfort and Energy Efficiency in a Building Located in Different Climate Regions

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Nikolaos Patsatzis; [2022]
    Keywords : building; thermal comfort; simulation;

    Abstract : One of the biggest challenges of a residential building, when it is designed, is to be energy efficient and to provide simultaneously many hours of thermal comfort throughout the year. So, this was the scope of this thesis: to perform a parametric analysis of thermal comfort and energy efficiency in a house that was designed for the climate of Gotland in Sweden. READ MORE

  2. 2. 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

  3. 3. 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

  4. 4. The environmental and social impact from digitization in buildings : A case study of the transformation and current conditions on the University hospital of Northern Sweden

  5. 5. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aniruddh Mohan; [2022]
    Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

    Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE
