21. Exploring the Effects of ICT on Environmental Sustainability: From Life Cycle Assessment to Complex Systems Modeling
Sammanfattning : The production and consumption of information and communication technology (ICT) products and services continue to grow worldwide. This trend is accompanied by a corresponding increase in electricity use by ICT, as well as direct environmental impacts of the technology. Yet a more complicated picture of ICT’s effects is emerging. LÄS MER
22. Sustainability and Flexural Behaviour of Textile Reinforced Concrete
Sammanfattning : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.

23. Lifetime Performance Assessment of Thermal Systems : Studies on Building, Solar and Disctrict Heating Applications
Sammanfattning : The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. LÄS MER
24. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability
Sammanfattning : Textile reinforced concrete (TRC) is an innovative high performance composite material consisting of open multi-axial textiles embedded in a fine-grained concrete matrix. Despite the fact that TRC-based research has revealed many promising attributes, it has yet to reach its recognition due to a lack of available design tools, standards and long-term behaviour.

25. A Life Cycle Approach to Environmental Sustainability in Aggregate Production Systems
Sammanfattning : Rock materials, such as sand, gravel, and crushed rock, serve as the foundation of our society. Known collectively as aggregates, these materials are essential for building foundations, concrete, and roads, making them the second most extracted material globally after water. LÄS MER
