  1. 16. Buildings as thermal energy storage – Pilot test and large-scale implementation for district heating systems

    Författare :Johan Kensby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space heating; Heat load; Heat demand; District heating; Thermal energy storage; Demand side management; Buildings;

    Sammanfattning : Heat loads in a district heating system can exhibit significant variations within a single day, which sets problematic conditions for efficient heat generation. Short-term thermal energy storage (TES) can decrease these daily variations and make the conditions for generating heat more favorable. LÄS MER

  3. 17. Vertical Extension of Buildings

    Författare :Rikard Nilsson; Avdelningen för Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Densification; energy-efficient renovation; Urban Development; Stakeholder;

    Sammanfattning : Many policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth. For example, by 2050 the aim is that the European Union will havereduced its greenhouse emissions by 90%. LÄS MER

  4. 18. Rum utan utsikt : Fönster och ljus i medeltida byggnader

    Författare :Linda Qviström; Anders Andrén; Herman Bengtsson; Martin Hansson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Medieval Archaeology; Post Medieval Archaeology; Windows; Medieval Buildings; Light Openings; Window Glass; View; Interiors; Darkness; Light; Lighting; Light Equipment; Arkeologi; historisk arkeologi; medeltida byggnader; fönster; ljusöppningar; fönsterglas; utsikt; inomhusmiljö; mörker; ljus; belysning; belysningsredskap; Uppland; Gotland; arkeologi; Archaeology;

    Sammanfattning : Windows, light and a view are self-evident parts of contemporary interiors. This was not the case in Scandinavia during the Middle Ages (c. 1050–1520 CE), when closed spaces without wall openings were standard. LÄS MER

  5. 19. Buildings' Transition to Active Nodes: Assessing the Viability of DC Distribution, PV and Battery Storage

    Författare :Patrik Ollas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Battery storage; Energy management; Solar photovoltaic; Direct current;

    Sammanfattning : Historically, buildings have been passive nodes in the electric grid system with one-way power flows. However, with the recent market development of solar photovoltaic (PV) and stationary behind-the-meter battery storage systems, buildings are now transitioning to active nodes, offering bi-directional power flows.

  7. 20. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs

    Författare :Kurt Källblad; Institutionen för byggvetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Computer Programs; Windows; Infiltration; Comfort; Walls; Indoor Climate; Climate; Ventilation; Cooling Load; Heating Load; Buildings; Thermal Models; Building Physics; Energy; Byggnadsteknik;

    Sammanfattning : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. LÄS MER
