  1. 1. Vibration reduction over junctions in buildings

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Alexander Forsberg; Aras Wali; [2021]
    Keywords : Vibration reduction; Junction; Building acoustics; Vibrations minskning; Knutpunkt; Byggnadsakustik;

    Abstract : Structure borne sound can travel multiple paths from one office to another and choosing to sound insulate a specific building element can be difficult since all the building elements are connected together and form a coupled system. The current approach by engineers when investigating transmission paths between spaces in a building is using a computer model and assuming that the junctions are firmly clamped or free. READ MORE

  3. 2. Assessing indoor environmental quality and occupant comfort in modern wood buildings with post-occupancy evaluation and building performance simulation

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Henriikka Taipale; [2021]
    Keywords : Climate change; Post-occupancy evaluation; Building performance simulation; Residential; Wood buildings; Engineered wood products; Indoor environmental quality; Thermal comfort; Indoor air quality; Acoustics; Visual comfort; Case study; Denmark; Technology and Engineering;

    Abstract : The European building sector is a source of significant negative environmental impacts, and large part of its carbon emissions can be attributed to heating, cooling and lighting of buildings – in other words, regulating buildings’ indoor environments. As people spend most of their lives indoors, there is a great challenge to create comfortable indoor environments, while also striving for further energy-efficiency and lower environmental impact.

    Abstract : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. READ MORE

  5. 4. Acoustic performance of timber volume elements

    University essay from Lunds universitet/Teknisk akustik

    Author : Oliver Olsson; [2020]
    Keywords : Impact sound insulation; Air-borne sound insulation; Cross laminated timber; CLT; Timber Volume Element; Vibration Insulation.; Technology and Engineering;

    Abstract : The thesis investigates the acoustic performance of light weight timber constructions known as timber volume elements and vibration insulation methods employed in these. Common materials used in light weight timber floor constructions and different floor configurations consisting of these materials were also studied. READ MORE

  6. 5. Climate Change Mitigation Measures of Load-Bearing Structure - A comparison of alternative structural designs using Life Cycle Assessment
