  1. 6. Bygga - Bruka - Riva : Energianvändning i småhus ur ett kretsloppsperspektiv

    Författare :Karin Adalberth; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; energy; single-unit dwellings; life-cycle; livscykelkostnader; småhus; LCA; energiförbrukning; kretslopp;

    Sammanfattning : This report deals with single-unit dwellings built in 1991 and 1992 in a city called Orebro, Sweden.The houses are prefabricated and the frameworks are made of wood. The aim of the essay is to present the total use of energy during the life-cycle of single-unit dwellings, taking their mode of construction into account. LÄS MER

  3. 7. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

    Författare :Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peak heat load shaving; renewable energy; ventilation heat recovery; frosting in heat exchangers; Heat transfer; förnybar energi; ventilation värmeåtervinning; frosting i värmeväxlare; värmeöverföring; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

  4. 8. Capacity-controlled Ground Source Heat Pump Systems for Swedish single-family dwellings

    Författare :Hatef Madani; Per Lundqvist; Joachim Claesson; Jose Miguel Corberan Salvador; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Pump; Capacity control; ground; ground source; geothermal;

    Sammanfattning : The overall objective of this thesis is to develop a structured method to approach the challenge of better understanding the techniques and potential for capacity control in Ground Source Heat Pump (GSHP) systems used in Swedish single-family dwellings. This thesis aims at development of a generic model of the system that can be used for comparative, descriptive, and predictive analysis of capacity controlled GSHP systems in single-family dwellings.

  5. 9. Modelling Life Cycle Cost for Indoor Climate Systems

    Författare :Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

    Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. LÄS MER

  7. 10. Energy efficiency and carbon dioxide mitigation in building stocks-

    Författare :Erika Mata Las Heras; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates the implementation of energy-saving measures (ESM) in existing building stocks from an energy systems perspective. The effects of the measures are assessed in terms of net and delivered energy levels, carbon dioxide (CO2) emissions, and the costs for implementing the measures. LÄS MER
