  2. 1. The variability in Salix BVOC emissions and possible consequences for managed SRC plantations

    Author : Tomas Karlsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Salix; BVOCs; varieties; age; branch chamber; leaf chambe; GC-MS; aerosols; Salix; BVOCs; varieties; age; branch chamber; leaf chamber; GC-MS; aerosols;

    Abstract : Willow (Salix spp.) trees have been used commercially since the 1980s to produce renewable energy. Some benefits with these trees are that they can clean soil from heavy metals, reduce the risk of nutrient leakage and eutrophication. READ MORE

  4. 2. Predicting the Energy Performance of Buildings : A Method using Probabilistic Risk Analysis for Data-driven Decision-support

    Author : Tomas Ekström; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; Probabilistic risk assessment; Risk analysis; Simulation and modeling; Field measurements;

    Abstract : As most countries worldwide continue to mitigate climate change, one area of focus is a building's energy efficiency. Buildings currently account for approximately 40 per cent of the total energy use in the European Union. One solution for reducing the energy demand from buildings is by continually implementing more stringent building regulations. READ MORE

  6. 4. Development and Application of Optical Diagnostics of Alkali Vapours for Solid Fuel Combustion

    Author : Tomas Leffler; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UV Absorption Spectroscopy; Alkali Vapour Pressure; KCl; KOH; NaCl; NaOH; high-temperature corrosion; Laser-induced Photofragmentation Fluorescence; slagging; fouling; reduced maintenance cost; Fysicumarkivet A:2016:Leffler;

    Abstract : Background: High amounts of alkali in the fuel, such as potassium and sodium in combination with high amounts of chlorine increase the chances of high-temperature corrosion, deposit growth and slagging and fouling. These risks need to be reduced to avoid losses in revenue due to unplanned stops and costs related to increased maintenance. READ MORE

  7. 5. Passive house renovation of Swedish single-family houses from the 1960s and 1970s : Evaluation of cost-effective renovation packages

    Author : Tomas Ekström; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Single-family houses (SFHs) constructed between 1961 and 1980 account for approximately one-third of the total energy use, 31 TWh, for space heating and domestic hot water in Swedish SFHs. These are responsible for about 40 percent of the total energy use in all buildings. READ MORE
