21. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : The building sector is responsible for approximately 40 % of the total energy usage in Sweden. In office buildings the heating, ventilation and air conditioning system can account for up to 55 % of the energy usage. In order to reduce the energy usage of the heating, ventilation and air conditioning system different control methods are often used. LÄS MER
22. Relativa fuktighetens påverkan på överlevnaden av virus i inomhusluft
Kandidat-uppsats, Lunds universitet/Institutionen för bygg- och miljöteknologiSammanfattning : Poor indoor air quality not only affects the comfort and health of us humans, but it can also contribute to the spread of bacteria and viruses if the conditions in the air are favourable for the virus. Several studies have been done where different virus survivability has been examined under different temperatures and relative humidity. LÄS MER
23. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD
Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskapSammanfattning : Abstract The impinging jet ventilation's importance in providing better air distribution and energy-efficient operation, as well as both its heating and cooling flexibility potential cannot be overemphasized. This is because acceptable indoor air quality and its environmental conditions are essential to occupant’s wellbeing, comfort, productivity, and improved cognitive function. LÄS MER
24. Thermal comfort study on a renovated residential apartment in Tjärna Ängar, Borlänge
Magister-uppsats, Högskolan Dalarna/EnergiteknikSammanfattning : The Swedish government in the 1960th initiated “The Million Program” to build million residentialunits to cover the housing shortage between 1965 to 1975. Tjärna Ängar neighborhood in Borlängemunicipality was built during the million-program period, where these residential units became old,and the indoor environment is uncomfortable for the residents.

25. Assessing indoor environmental quality and occupant comfort in modern wood buildings with post-occupancy evaluation and building performance simulation
Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : 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.
