  2. 21. Perceptions of intensive forestry and multi-storey wood frames among Swedish actors

    Author : Kerstin Hemström; Krushna Mahapatra; Ole Jess Olsen; Anders Lunnan; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey wood frames; intensive forestry; actor perceptions; legitimacy; path dependence; Byggteknik; Civil engineering;

    Abstract : Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. READ MORE

  4. 22. Windows and blinds selection for enhancing subjective well-being

    Author : Elaheh Jalilzadehazhari; Jimmy Johansson; Krushna Mahapatra; Peter Johansson; Myriam Aries; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subjective well-being; perceived control; controllability; analytical hierarchy process; non-dominated sorting genetic algorithm-II; Byggteknik; Civil engineering;

    Abstract : Earlier studies in the context of windows and blinds selection have mostly tried to increase the awareness regarding various effects of windows and blinds selection on subjective well-being, including their effect on visual comfort, thermal comfort, energy consumption and life cycle cost. However, the main problem is the potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. READ MORE

  5. 23. Vibrations in timber floors : Dynamic properties and human perception

    Author : Kirsi Jarnerö; Anders Professor; Tomi Toratti; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

    Abstract : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. READ MORE

    Abstract : The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material.
