  1. 11. Energy efficient indoor climate control - A practical approach for enhanced implementability

    Författare :Mattias Gruber; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model-based control; building automation; ventilation and air-conditioning; office buildings; implementability; energy efficiency; Heating; indoor climate control;

    Sammanfattning : This work deals with energy efficient indoor climate control in office buildings, with an emphasis on implementability. More specifically, the aim is to suggest and evaluate improvements to building automation systems that are sufficiently simple and efficient to be realistic alternatives to commonly-used systems.

  3. 12. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

    Författare :Vahid Nik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

    Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

  4. 13. Modelling LCC for Different Indoor Climate Systems

    Författare :Dennis Johansson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kallt klimat; bostäder; kontor; skolor; samlingslokaler; inomhusklimat; VVS; uppvärmning; ventilation; luftkonditionering; livscykelkostnader; kostnader; optimering; beräkningsmetoder; beräkningsmodeller; teori;

    Sammanfattning : 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. LÄS MER

  5. 14. Modelling and Intelligent Climate Control of Buildings

    Författare :Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Chalmers University of technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; indoor climate control; operative temperature; demand controlled ventilation; prediction; feed-forward control;

    Sammanfattning : The main purpose of the work presented in this thesis is to examine the possibilities of different control techniques together with intelligent building technology to improve the indoor climate and/or the energy efficiency of buildings. In particular, the possibilities of measuring more variables and using them as input to the controllers are examined. LÄS MER

  7. 15. Determination and control of some pollutants in indoor environments

    Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Sammanfattning : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. LÄS MER
