  2. 1. Thermal stresses in load-bearing glass-timber components

    Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

  4. 2. Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

    Author : Lisandra Fachinello Krebs; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Computer simulations; Extensive green roofs; Housing projects; Indoor thermal comfort; Leaf area index; Microclimate; Social housing; Sustainability; Thermal comfort;

    Abstract : Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. READ MORE

  5. 3. Borehole heat store design optimization

    Author : Bo Nordell; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. READ MORE

  6. 4. Heating and Cooling Requirements in Commercial Buildings. A duration curve model including building dynamics

    Author : Per-Erik Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC system; cooling requirements; duration curve; heating requirements; commercial building; heat balance; balance curve; energy analysis;

    Abstract : In many European countries, especially, the heat loss due to transmission and air leakage, in many buildings today, is only a fraction of what it was in those built in the early 70's. At the same time there have been changes in the way the buildings are used which, among other things, has lead to an often considerable increase of the internal heat loads. READ MORE

  7. 5. Thermal comfort and energy in residential buildings in a cold climate

    Author : Petter Lundqvist; Mikael Risberg; Erik Elfgren; Patrik Rohdin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. READ MORE
