  1. 6. Solar Colletors Combined with Ground-Source Heat Pumps in Dwellings - Analyses of System Performance

    Författare :Elisabeth Kjellsson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heating in dwellings; TRNSYS simulations; solar collectors; ground-source heat pumps; ground heat;

    Sammanfattning : The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced. LÄS MER

  3. 7. A Sociological Approach to Indoor Environment in Dwellings : Risk factors for Sick Building Syndrome (SBS) and Discomfort

    Författare :Karin Engvall; Dan Norbäck; Eva Sandstedt; Göran Strid; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Indoor environment; Questionnaire; Atopy; Building age; Indoor air quality; Sick building syndrome SBS ; Validation; Dwelling; Energy conservation; Mechanical ventilation; Building dampness; Building reconstruction; Wood heating; Electric heating; Heat pump; Thermal Insulation; Sealing; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. LÄS MER

  4. 8. Indoor Environment in Dwellings and Sick Building Syndrome (SBS) : Longitudinal Studies

    Författare :Bo Sahlberg; Dan Norbäck; Berndt Stenberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Indoor environment; sick building syndrome SBS ; dwelling; longitudinal cohort study; building dampness; mould; microbial volatile organic compounds MVOC ; biomarkers; asthma; risk factors; Arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : People spend most of their time indoors and mostly in the dwelling. It is therefore important to investigate associations between indoor exposure in dwellings and health. Symptoms that may be related to the indoor environment are sometimes referred to as the "sick building syndrome" (SBS). LÄS MER

  5. 9. The role of Swedish single-family dwellings in the electricity system - The importance and impacts of solar photovoltaics, demand response, and energy storage

    Författare :Emil Nyholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electricity system models; Electric space heating; Batteries; Demand response; Single-family dwellings; Demand side management; Optimization; Solar photovoltaics; Distributed generation;

    Sammanfattning : This thesis investigates the role Swedish single-family dwellings can play in the electricity system. Both through becoming electricity producers through the use of solar photovoltaic (PV) systems, and the possibilities of demand response (DR) and energy storage in combination with this, and through the DR of electric space heating in the dwellings.

  7. 10. A multi-method assessment to support energy efficiency decisions in existing residential and academic buildings

    Författare :Shoaib Azizi; Thomas Olofsson; Gireesh Nair; Olga Kordas; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential dwellings; institutional buildings; sustainability; energy renovation; adoption of technology; decision-making; smart solutions; ICT; IoT; sustainability; hållbarhet;

    Sammanfattning : Rapid decarbonization of building stock is essential for the energy transition required to mitigate climate change and limit the global temperature rise below 1.5 °C. The decision-making for the adoption of energy efficiency measures (EEMs) is often complex and involves lasting consequences and risks. LÄS MER
