  1. 1. Demand controlled ventilation : Impact on energy use and indoor environmental quality

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Therese Ottosson; [2023]
    Nyckelord :;

    Sammanfattning : European buildings account for a significant share of the energy-related emissions in Europe. Addressing the increasing energy use and its contribution to greenhouse gases (GHG) is internationally recognized as crucial, and emissions must be halted. LÄS MER

  3. 2. Optimization of comfort-related energy and thermal comfort for commuter trains : A case study of Stockholm commuter trains

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jimmy Lidén; [2023]

    Sammanfattning : Today, energy efficiency is an increasingly important question in which progress is accelerating. One of the high electricity demand energy users is public transport. In addition, passenger satisfaction with thermal comfort is an important parameter. LÄS MER

  4. 3. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Martin Fagernäs; [2021]
    Nyckelord :Demand Controlled Ventilation; DCV; Heat Recovery Unit;

    Sammanfattning : The building sector is responsible for approximately 40 % of the total energy usage in Sweden. In office buildings the heating, ventilation and air conditioning system can account for up to 55 % of the energy usage. In order to reduce the energy usage of the heating, ventilation and air conditioning system different control methods are often used. LÄS MER

  5. 4. Energibesparing med bergvärmepump och värmeväxlare : Månadsvisa beräkningar för ett nytt och ett äldre småhus i Västerås samt en jämförelse mot kraven för nära-nollenergibyggnader

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Sara Hilbert Wiman; [2021]
    Nyckelord :Bedrock heating; HRV; heat exchanger; energy efficient; energy performance requirements; nearly zero-energy buildings; detached houses; Bergvärme; FTX; värmeväxlare; energieffektivt; energiprestandakrav; äldre småhus; nybyggnation; nära-nollenergibyggnader;

    Sammanfattning : Purpose: This degree project aims to see how the energy demand from active heating of detached houses can be improved to meet the energy performance requirements set for nearly zero-energy buildings by Boverket (The Swedish National Board of Housing, Building and Planning). Method: To accomplish this, the benefits from two different energy-saving installations are studied: bedrock heat pumps and heat exchangers in Heat Recovery Ventilation Systems (HRV-systems).
