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

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

   Sammanfattning : 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.

   Sammanfattning : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. LÄS MER

5. 14. The Municipal Equalization System and its Implications for Economic Growth and Efficiency

   Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Evelina Sundin; Evy Dufvenberg Ivarsson; [2023]
   Nyckelord :The Municipal Equalization System; Income Equalization; Cost Equalization; Sweden; Fiscal Federalism; Economic Efficiency; Marginal Effects; Business and Economics;

   Sammanfattning : This paper investigates the correlation between Sweden's municipal equalization system and economic growth and efficiency for the years 2005 to 2022. This paper uses panel data for all 290 municipalities and a fixed effects model to study the two main parts of Sweden's municipal equalization system: the income equalization system and the cost equalization system.
