    Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER

  2. 7. Industrial Construction Methods for Cost-Effective and Sustainable Multi-Storey Buildings

    Författare :Hanif Pourghazian; Folke Björk; Anne Landin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : Reduction of the cost of construction is a constant goal for the building industry. One way of reducing the construction cost of buildings is to develop building technologies that will give increased productivity. Reduced construction time at the building-site and waste of materials and resources contribute to furtherreduction of the costs. LÄS MER

  3. 8. Conflict and Compromise : An Evolutionary Framework for the Design of Multi-Storey Timber Buildings

    Författare :Magnus Larsson; Andreas Falk; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : In January 1995, the architect John Frazer’s groundbreaking study, An Evolutionary Architecture, was published to coincide with an exhibition of the same name at the Architectural Association in London. The book proposed a new methodology for the architectural design process, based on a radical repositioning of the role of the architect. LÄS MER

  4. 9. Diffusion of innovative domestic heating systems and multi-storey wood-framed buildings in Sweden

    Författare :Krushna Mahapatra; Leif Gustavsson; Ole Jess Olsen; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Sammanfattning : The diffusion of innovations that promote sustainable use of forest resources and energy efficiency is important for reducing greenhouse gas emission and dependency on oil. In this thesis the ‘systems of innovation’ (SI)The SI analyses showed that several sources of path dependency, resulting from the establishment and growth of the concrete-based construction system over the past 100 years, hinder the expansion of a wood-based multi-storeyThe adopter-centric approach included household questionnaire surveys: one covering the whole of Sweden in 2004 involving 1500 randomly selected homeowners with any type of heating system, and another in the city of Östersund inThe expansion of district heating networks in the detached home sector, particularly those homes with resistance heaters, is often considered difficult.

    Sammanfattning : An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. LÄS MER
