  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.

    Abstract : The building sector is one of the sectors with the highest energy utilization and is one of the largest sources of CO2 emissions worldwide. At the same time, energy prices in Europe have significantly increased in recent years. READ MORE

  3. 3. Supercooling Simulation of Latent Heat Based Storage : A simulation model built in COMSOL Multiphysics

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

    Author : OLLE CEDELL; [2022]
    Keywords : ;

    Abstract : The energy demand in the building sector makes up a large portion of our energy consumption. The industrial sector is also energy intense and oftentimes loses a great deal as surplus heat. READ MORE

  4. 4. Energy supply system for a high-rise building in Germany : Optimization of a heating and cooling supply system made with plant simulations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Ida Almén; Elin Johansson; [2022]
    Keywords : energy supply system; absorption chiller; compression chiller; Germany;

    Abstract : The building sector has great potential for energy savings since it is responsible for nearly a third of the global energy use. As oil, coal and natural gas continues to hold a big share of the energy mix it is important to work towards introducing more renewable energy alternatives. READ MORE

  5. 5. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emil Nilsson; [2021]
    Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

    Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.
