1. 16. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

   Författare :Markus Peterson; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

   Sammanfattning : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. LÄS MER

3. 17. Rethinking refurbishment projects for improved users' working environment

   Författare :Elna Jönsson; Avdelningen för Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refurbishment; Users working environment; Project governance; Briefing; Facility management; Post-occupancy evaluation;

   Sammanfattning : The built environment is important to achieve a sustainable society. From a sustainability perspective, refurbishment can be preferable to building anew. A significant proportion of the built environment needs to be refurbished. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand Response; Flexible loads; Building stock energy-use; Bottom-up simulation models; Load profiles; Non-homogeneous Markov-chains; End-user behavior; Lumped capacitance models; HVAC system control; Smart Grid.; Efterfrågeflexibilitet; Flexibla laster; Energianvändning i byggnadsstocken; Botten-upp-simuleringsmodeller; Elförbrukningsprofiler; Icke-homogena Markovkedjor; Slutanvändarbeteenden; Värmedynamikmodellering; Styrning av HVAC-laster; Smarta elnät.;

   Sammanfattning : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. LÄS MER

5. 19. Vertical Extension of Buildings

   Författare :Rikard Nilsson; Avdelningen för Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Densification; energy-efficient renovation; Urban Development; Stakeholder;

   Sammanfattning : Many policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth. For example, by 2050 the aim is that the European Union will havereduced its greenhouse emissions by 90%. LÄS MER

7. 20. Communication of life cycle assessment results : life cycle key performance indicators

   Författare :Helena Nydahl; Thomas Olofsson; Anders P. Åstrand; Staffan Andersson; Åsa Wahlström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Monetary Valuation; Climate Impact; Life Cycle Key Performance Indicators; Global Warming Potential; LCA-result communication; Interpretation of LCA-results; climate change; klimatförändringar;

   Sammanfattning : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. LÄS MER
