  1. 1. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Jonathan Karlsson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Abstract : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

  2. 2. Comfort Climate Evaluation with Thermal Manikin Methods and Computer Simulation Models

    University dissertation from Stockholm : Byggvetenskap

    Author : Håkan O Nilsson; [2004]
    Keywords : thermal climate assessment; thermal environment; office environment; cabin; climate; CFD; thermal manikin; comfort zone diagram;

    Abstract : Increasing concern about energy consumption and thesimultaneous need for an acceptable thermal environment makesit necessary to estimate in advance what effect differentthermal factors will have on the occupants. Temperaturemeasurements alone do not account for all climate effects onthe human body and especially not for local effects ofconvection and radiation. READ MORE

  3. 3. Cold exposure and thermal comfort among patients in prehospital emergency care innovation research in nursing

    University dissertation from Stockholm : Byggvetenskap

    Author : Jonas Aléx; Britt-Inger Saveman; Stig Karlsson; Ulf Björnstig; Inggard Lereim; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thermal comfort; thermal discomfort; cold exposure; cold stress; hypothermia; patients’ experiences; active warming; prehospital emergency care; finger temperature; back temperature; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Abstract : BackgroundPatients’ cold exposure is a neglected problem in prehospital emergency care. Cold stress increases pain and anxiety and contributes to fear and an overall sense of dissatisfaction. When left untreated, cold stress disturbs vital body functions until ultimately reaches hypothermia. READ MORE

  4. 4. Influence of thermal mass on the heating and cooling demands of a building unit

    University dissertation from Stockholm : Byggvetenskap

    Author : Fredrik Ståhl; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal mass; environmental impact; thermal comfort; heat storage; life cycle; building energy use; earth tube heat exchanger; comfort interval; heavy or light buildings; building structure;

    Abstract : The purpose of this work is to find to what extent the thermal properties of the building materials, the allowed indoor temperature swing, determined by the comfort interval, and, to some extent, the ventilation strategy can affect the heating and cooling demand of a building. It is well known that a thermally heavy building, that is a building with a high heat capacity, often demands less energy for heating and cooling and have a more stabile indoor temperature due to heat storage in the building structure.

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

    University dissertation from Department of Architecture and Built Environment, Lund University

    Author : Lisandra Fachinello Krebs; [2018-11-07]
    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
