1. 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)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.

2. Lowering energy need and improving indoor climate - A case study of rural dwellings in Gammalsvenskby, Ukraine
University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesignAbstract : A vast majority of rural dwellings in Ukraine are inefficient from an energy perspective, with a major need for energy-efficient renovations. A lot of these buildings are also having problems with the indoor climate, with poor ventilation combined with indoor combustion of fuel which can cause negative health effects. READ MORE

3. Predicting Indoor Carbon Dioxide Concentration using Online Machine Learning : Adaptive ventilation control for exhibition halls
University essay from Jönköping University/Tekniska HögskolanAbstract : A problem that exhibition halls have is the balance between having good indoor air quality andminimizing energy waste due to the naturally slow decrease of CO2 concentration, which causes Heat-ing, Ventilation and Air-Conditioning systems to keep ventilating empty halls when occupants have leftthe vicinity. Several studies have been made on the topic of CO2 prediction and occupancy predictionbased on CO2 for smaller spaces such as offices and schools. READ MORE

4. Deep Reinforcement Learning for Temperature Control in Buildings and Adversarial Attacks
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Heating, Ventilation and Air Conditioning (HVAC) systems in buildings are energy consuming and traditional methods used for building control results in energy losses. The methods cannot account for non-linear dependencies in the thermal behaviour. READ MORE

5. Performance Evaluation of Ground Heating and Cooling Systems - Long-term performance measurements of two case buildings
University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöAbstract : Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. READ MORE
