11. Re-viewing industrial energy-efficiency improvement using a widened system boundary
Sammanfattning : Improved energy efficiency in industry is important for reaching the targets within the EU strategy for increased sustainability. However, energy efficiency is not always prioritised within companies, and the improvement potential remains large. This paradox called an energyefficiency gap is explained by energy-efficiency barriers. LÄS MER
12. Distributed thermal response tests : New insights on U-pipe and Coaxial heat exchangers in groundwater-filled boreholes
Sammanfattning : U-pipe Borehole Heat Exchangers (BHE) are widely used today in ground source heating and cooling systems in spite of their less than optimal performance. This thesis provides a better understanding on the function of U-pipe BHEs and Investigates alternative methods to reduce the temperature difference between the circulating fluid and the borehole wall, including one thermosyphon and three different types of coaxial BHEs.

13. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations
Sammanfattning : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

14. Improved energy efficiency in industrial small and medium-sized enterprises : Regional energy efficiency network policy programs
Sammanfattning : Despite large potential for improved energy efficiency in industrial small and medium-sized enterprises (SMEs), the full potential is not realized due to barriers to energy efficiency. Two primary ways to realize the potential are to deploy energy management practices and conduct energy audits. LÄS MER
