1. A Systematic Approach to Integrated Building Performance Assessment and Visualisation
Sammanfattning : The aim of this project was to develop a holistic approach to building-performance assessment without limiting it to energy use (usually expressed in kWh/m2/year), but rather include more parameters that represent the following aspects: Economic, environmental, and quality of service provided to the occupant/client. If it can be shown that buildings can be operated not only in an energy-efficient way, but also in a way that takes into consideration the needs of the occupants, a case could be built that a higher quality of indoor environment does not necessarily mean a higher economic impact.

2. Ground heat storage : thermal analyses of duct storage systems
Sammanfattning : [abstract missing].... LÄS MER
3. Aeroacoustics Studies of Duct Branches with Application to Silencers
Sammanfattning : New methodologies and concepts for developing compact and energy efficient automotive exhaust systems have been studied. This originates in the growing concern for global warming, to which road transportation is a major contributor. LÄS MER
4. Aerodynamics of an Aeroengine Intermediate Compressor Duct: Effects from an Integrated Bleed System
Sammanfattning : With the successful development of high-bypass-ratio turbofan engines, major aerodynamic components have been optimized and continuous efficiency improvements are getting harder to maintain. Therefore, to meet the requirements of lower emission of greenhouse gases, auxiliary modules such as intermediate ducts are receiving increasing interest. LÄS MER
5. Behovsstyrd ventilation i lokalbyggnader-Innebörd och strömningstekniska konsekvenser
Sammanfattning : In todays society energy efficiency and energy savings are becoming increasingly important. The building sector represents a major part of Swedens total use of energy. Furthermore, ventilation constitutes the single largest factor in the energy balance of buildings. LÄS MER
