  1. 1. Economic and Environmental Benefits of CHP-based District Heating Systems in Sweden

    Författare :Shahnaz Amiri; Björn G. Karlsson; Louise Trygg; Mats Westermark; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO2) and other greenhouse gases and their impact on climate change.

  2. 2. On the Effect of Occupant Behavior and Internal Heat Gains on the Building’s Energy Demand : A case study of an office building and a retirement home

    Författare :Jakob Carlander; Bahram Moshfegh; Jan Akander; Shahnaz Amiri; Sture Holmberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; energy efficiency indicators; occupant behaviour; energy performance; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : About 12% of the greenhouse gas emissions and 40% of the total energy use in the EU derive from the buildings. User behavior, construction, and HVAC systems has a significant impact on a building’s energy use. If a building is to be energy-efficient it is important to understand how all these parameters are connected. LÄS MER

  3. 3. A Statistical Approach to Estimate Thermal Performance and Energy Renovation of Multifamily Buildings : Case study on a Swedish city district

    Författare :Martin Eriksson; Bahram Moshfegh; Shahnaz Amiri; Jan Akander; Sasan Sadrizadeh; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy signature; multifamily building; district heating; energy renovation; simulation; heat loss coefficient; balance temperature; base load; energisignatur; flerbostadshus; fjärrvärme; energirenovering; simulering; värmeförlustkoefficient; balanstemperatur; baslast; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Several climate and energy goals have been set in the European Union, one of them being to increase energy efficiency. In Sweden, a large potential for increased energy efficiency lies in the residential and service sectors, which account for about 40% of total energy use. LÄS MER

  4. 4. Efficiency of heat and work in a regional energy system

    Författare :Tommy Rosén; Louise Ödlund; Shahnaz Amiri; Erik Dotzauer; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the largest flows of energy in Swedish municipalities is the fuel-energy flow through the regional combined heat and power (CHP) plant. The customer products from this flow are mainly electricity to the electricity grid and heat to the building sector. LÄS MER

  5. 5. Energy System Collaboration as a Vital Measure to Improve District Heating Performance

    Författare :Gottfried Weinberger; Bahram Moshfegh; Shahnaz Amiri; Erik Dahlquist; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system collaboration; District heating; Industrial excess heat; Combined heat and power; Energy system optimization; Metamodeling; Building LCC optimization; Building energy simulation; Cluster energy renovation; Energisystemsamverkan; Fjärrvärme; Industriell överskottsvärme; Kraftvärme; Energisystemoptimering; Metamodellering; Byggnads-LCC-optimering; Byggnadsenergisimulering; Klusterenergirenovering; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.
