    University dissertation from Lund University, Lund Institute of Technology, Division of Building Services, P.O. Box 118, SE-22100 LUND, Sweden

    Author : Birgitta Nordquist; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat exchanger efficiency; duct design; balancing; disturbance; tracer gas measurements; analytical model; window opening; single-sided ventilation; ventilation; schools; sensitivity analysis; Building construction; Byggnadsteknik;

    Abstract : Popular Abstract in Swedish Syftet har varit att studera tillämpningen av ventilation i skolbyggnader. Huvuddelen av avhandlingen behandlar vädring av klassrum. Analytiska modeller med vilka luftutbytet orsakat av vädring kan beräknas föreslås. Ett mål är att modellerna skall utgöra ett verktyg för projektörer och brukare. READ MORE

  2. 2. Investigating Dwellings' Response to Heating Power Cuts : Simulations and Field Tests

    University dissertation from Lund University, Lund Institute of Technology, Division of Building Services, P.O. Box 118, SE-22100 LUND, Sweden

    Author : Victor Fransson; Lunds universitet.; Lund University.; [2017-04-07]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Reducing energy use, increasing the use of renewable energy sources, and adapting to stricter building regulations and certification systems – these are all examples of the challenges facing the building industry and society. Looking at the energy supply at a larger scale than a single building, like a neighborhood or a city, the stack effect of peak power demands can cause problems on the production side, either economical or concerning the environment and greenhouse gases when fossil fuel is used to cover these peaks.

  5. 5. Modelling LCC for Different Indoor Climate Systems

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Dennis Johansson; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kallt klimat; bostäder; kontor; skolor; samlingslokaler; inomhusklimat; VVS; uppvärmning; ventilation; luftkonditionering; livscykelkostnader; kostnader; optimering; beräkningsmetoder; beräkningsmodeller; teori;

    Abstract : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. READ MORE
