1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Doris Dijak; Elin Torstensson; [2023]
   Keywords : Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

3. 2. Possibility for Positive Energy Retrofit in Borlänge

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
   Keywords : ;

   Abstract : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. READ MORE

5. 4. Life Cycle Assessment of Borehole Thermal Energy Storage

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Saga Karlsson; [2022]
   Keywords : ;

   Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

6. 5. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE
