    Energibalansen för ett nytt flerbostadshus i Mellansverige: Beräkningar intervjuer och analys av energikraven i Boverkets Byggregler2010Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave

    Abstract

     

     

     

    This degree project comprises 30 credits, i.e. 20 weeks of work. The work mainly deals with the energy balance for a multi-family house in Västerås and the requirements for energy conservation in the Swedish building code, BBR. Calculations of the energy balance are supplemented by a number of interviews.

     

    Energy conservation in general has become more important in recent years and the subject is in line with increased public awareness. This importance and attention is explained by environmental problems in general and global warming in particular, but also by rising energy prices. The Swedish authority Boverket has gradually changed the regulatory framework in order to improve the energy efficiency for new buildings. Boverket issues the Swedish building code BBR which includes energy requirements for buildings. The new BBR 16 was published after only about 6 month after the previous version BBR 15.

     

    This degree project includes a commission from the company Abetong AB to compare the previous BBR 15 against the new BBR 16 and find any changes, and compile these changes as clear as possible. The work also includes answers to some specific questions from the same company. One question is whether existing multi-family houses from the company would meet the new energy requirements of BBR 16. The energy balance of these houses is studied specifically when an exhaust air heat pump or a ventilation heat exchanger is used in order to save energy. To make this work particularly interesting, the window area was changed to see how this would affect the energy use in the buildings.

     

    To answer these questions, the energy simulation program VIP+ was used for calculations. These computer calculations have also been supplemented by hand calculations as a control measure. All results from the different calculations are put together and analyzed in this report.

     

    The overall conclusion from the calculation results is that the existing multi-family houses perform well with the present technology, and that they meet the new energy requirements in BBR 16. This means that no further measures in order to save energy in the houses are necessary in order to meet the newest requirements.

    Abstract [en]

    Abstract

    The tests work is about the subject "synergism of steel and concrete."

    The construction sector is in a strong competition and the different companies in the Prefab

    Market has ever tried to develop new design solutions that are efficient and environmentallyfriendly.

    The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction .
