1. Efficiency factors for space heating system in buildings
Sammanfattning : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. LÄS MER
2. Uthålligt lärande om värmen? : Domesticering av energiteknik i passivhus
Sammanfattning : Den vanligaste lösningen på problemet att för mycket energi används i den byggda miljön är implementering av energieffektiv teknik. Men installation av teknik räcker sällan för att nå förväntad energibesparing: det är människor som i sin vardag använder tekniken och de använder den inte alltid på det sätt som teknikutvecklarna har tänkt sig.

3. Evolution of Future Heating Systems - Modeling of an Expanding City Using a Dynamic Systems Approach
Sammanfattning : Reducing greenhouse gas emissions is central to meeting climate change mitigation targets. Since the energy sector is one of the largest greenhouse gas emitters, it is essential that all the actors within the energy sector reduce their respective emissions. LÄS MER
4. Buildings and district heating - contributions to development and assessments of efficient technology
Sammanfattning : The objective of this thesis is to contribute to improved performance of district heating systems by focusing on three items. Item 1: Study of three methods for improving the performance of sub-systems within buildings connected to the distribution network. The methods can be considered as more or less innovative. LÄS MER
5. 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.
