  1. 1. Energy performance of residential buildings : projecting, monitoring and evaluating

    Författare :Itai Danielski; Morgan Fröling; Anna Joelsson; Tomas Kåberger; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Energy security and climate change mitigation have been discussed in Sweden since the oil crisis in the 1970s. Sweden has since then increased its share of renewable energy resources to reach the highest level among the EU member states, but is still among the countries with the highest primary energy use per capita.

  3. 2. Vibrations in Lightweight Buildings - Perception and Prediction

    Författare :Juan Negreira; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psycho-vibratory evaluation; Vibrations; Timber floors; Lightweight; Measurements; Serviceability criteria; Vibration annoyance; Vibration acceptability; Elastomer; Finite element method; Prediction Tools.;

    Sammanfattning : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. LÄS MER

  4. 3. Vernacular Buildings and Urban Social Practice - Wood and people in Early Modern Swedish Society

    Författare :Andrine Nilsen; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; historical archaeology; early modern; city scape; urbanity; Swedish building practices; building stock; log timber construction; timber-framing technique; post and plank construction; storeyed buildings; mixed techniques; the production of space; social dimensions; centre; periphery; marginality;

    Sammanfattning : Wooden houses were major components of the early modern Swedish townscape. Yet, today these buildings have largely disappeared due to fires, demolition and modernity. The main themes of the thesis are the study of what kind of wooden building techniques were used within the urban environment. LÄS MER

  5. 4. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling

    Författare :Åsa Bolmsvik; Torbjörn Ekevik; Andreas Linderholt; Anders Brandt; Anders Ågren; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden framed structure; light weight buildings; multi-storey; flanking transmission; junction; vibration distribution; impact noise; damping; elastomers; finite element analysis; experimental modal analysis; FRF; trästomme; träkonstruktion; träbyggnad; flervåningshus; EMA; FEM; flanktransmission; koppling; knutpunkt; vibrationsspridning; stomljud; stegljud; dämpning; elastomerer; finit elementmetod; experimentell modalanalys; accelerationsmätning; frekvensresponsfunktion; modalanalys;

    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

  7. 5. Hus och gård i Hälsingland : en studie av agrar bebyggelse och bebyggelseutveckling i norra Hälsingland Kr.f.-600 e.Kr

    Författare :Lars Liedgren; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Roman Iron Age; Migration Period; Central Norrland; Hälsingland; sedentary; establishment of settlement; colonization; settlement expansion; farm site; house foundations; graves; house foundation terraces; building constructions; three-aisled houses; agrarian; cultivation; cereals; macro-fossil analysis; metalwork.;

    Sammanfattning : The subject of this dissertation is the sedentary agrarian settlement in northern Hälsingland and how it developed during the period AD 1-600.The study is based on a body of archaeological source material comprising archaeological remains and finds which can be linked to the sedentary agrarian economy.
