  1. 1. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Martin Fagernäs; [2021]
    Keywords : Demand Controlled Ventilation; DCV; Heat Recovery Unit;

    Abstract : 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. READ MORE

  3. 3. Introduktion av pyrolysanläggning i Eksjö fjärrvärmenät : en undersökning om pyrolysanläggningars förutsättningar och eventuella roll inom fjärrvärmeproduktion

    University essay from SLU/Dept. of Energy and Technology

    Author : Karl Malmberg; [2021]
    Keywords : biokol; värmeproduktion; kolsänka; sågverk; biprodukter;

    Abstract : In order to fulfill the Swedish national goal of achieving climate neutrality by 2045, the implementation of negative emission technologies is regarded as a vital tool, since it can compensate for emissions deemed too hard to avoid. The widespread use of district heating systems, in combination with a relatively large forest industry in Sweden, provides a unique opportunity to implement combined biochar and energy production (BCE).

  4. 4. Life Cycle Sustainability Assessment of Energy renovations. A case-study of a multi-family building in Sweden

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

    Author : Georgia Betsi; [2021]
    Keywords : Energy renovations; Life Cycle Assessment; Life Cycle Costing; Life Cycle Sustainability Assessment; Shadow cost; Technology and Engineering;

    Abstract : Various renovations were applied to the existing post-war building stock of the so called “Swedish Million Program”, that were built during the 1965 and 1974 period. Only 20% of those buildings were renovated and still the rest of them remains in need of vast renovations, to mitigate the climatic impact of the existing building stock. READ MORE

  5. 5. Techno-economic Analysis and Market Potential Study of Solar Heat in Industrial Processes : A Fresnel Direct Steam Generation case study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Guillermo de Santos López; [2021]
    Keywords : Solar heat in industrial processes; techno-economic analysis; market potential; direct steam generation; Fresnel technology;

    Abstract : The industrial sector not only has a big contribution to global emissions but also a low share of renewable energy for heat demand. Knowing that most of the energy consumption in industry is heat and that half of it is at medium-low temperature (below 400 ºC), it is a great market for the integration of solar thermal technologies.
