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

    Författare :Fredrik Ståhl; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. 14. Impact of moisture on long term performance of insulating products based on stone wool

    Författare :Tomás Vrána; Folke Björk; Per Ingvar Sandberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral insulation; Stone wool; Material properties; Moisture transport; Heat transport; Test equipment; Moisture properties; Frost formation; Building engineering; Byggnadsteknik;

    Sammanfattning : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. LÄS MER

  7. 15. Characterisation and Consolidation of Historical Lime Mortars in Cultural Heritage Buildings and Associated Structures in East Africa

    Författare :Athuman M. K. Ngoma; Jonas Holmgren; Jan Erik Lindqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; East Africa; Stone Town; historical building; mortar; deterioration; consolidation; calcium hydroxide solution; Building engineering; Byggnadsteknik;

    Sammanfattning : For the period of several centuries, the influence of several distinct cultures produced rich and diverse cultural heritage that we see today in East Africa countries. The most tangible remains of these heritages are stone built buildings and structures including, palaces, mosques, residential houses and tombs. LÄS MER
