  1. 1. Modelling and Intelligent Climate Control of Buildings

    Författare :Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Mohsen Soleimani-Mohseni; Chalmers University of technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. Decision making on indoor climate control in historic buildings : knowledge, uncertainty and the science-practice gap

    Författare :Gustaf Leijonhufvud; Tor Broström; Simon Stefan; University of Gothenburg; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preventive conservation Environmental control; Energy efficiency; Decision-making; Knowledge sharing;

    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.

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

    Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  4. 4. The reinforcement learning method : A feasible and sustainable control strategy for efficient occupant-centred building operation in smart cities

    Författare :Ross May; Kenneth Carling; Mengjie Han; Pascal Rebreyend; Zoltan Nagy; Högskolan Dalarna; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov decision processes; Reinforcement learning; Control; Building; Indoor comfort; Occupant; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Mikrodataanalys; Microdata Analysis;

    Sammanfattning : Over half of the world’s population lives in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. LÄS MER

  5. 5. Latent Heat Thermal Energy Storage for Indoor Comfort Control

    Författare :NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []

    Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER
