  1. 1. Modelling and intelligent climate control of buildings

    Författare :Mohsen Soleimani-Mohseni; [2005]
    Nyckelord :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

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

    Författare :Mattias Gruber; [2014]
    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. 3. Demand based control of indoor climate in office buildings. Design of local and central feed-forward control systems for high comfort, low energy use and low peak power

    Författare :Mattias Gruber; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand based control; IAQ; central control; local control; disturbance rejection; thermal climate; HVAC; energy efficiency; feed-forward; Building services engineering; office buildings;

    Sammanfattning : In this work, a number of novel strategies for controlling the heating, ventilation and air-conditioning (HVAC) systems in office buildings have been designed and evaluated. The purpose of the control strategies is to improve the match between what is supplied by the HVAC-systems and what is required to achieve a desirable indoor climate in the building. LÄS MER

  4. 4. Decision making on indoor climate control in historic buildings knowledge, uncertainty and the science-practice gap

    Detta är en avhandling från Göteborg : Acta Universitatis Gothoburgensis

    Författare :Gustaf Leijonhufvud; Göteborgs universitet.; Gothenburg University.; [2016]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Preventive conservation Environmental control; Energy efficiency; Decision-making; Knowledge sharing; Preventive conservation; Environmental control;

    Sammanfattning : Balancing use, preservation and energy use is a fundamental challenge for the whole heritage field. This is put to the point in designing and operating systems for indoor climate control in historic buildings, where competing objectives such as preservation, comfort, accessibility, energy use and cost have to be negotiated in the individual case.

  5. 5. Determination and control of some pollutants in indoor environments

    Detta är en avhandling från Division of Medical Microbiology

    Författare :Pawel Markowicz; [2014]
    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
