  2. 2. Sustainable building ventilation solutions with heat recovery from waste heat

    University dissertation from KTH Royal Institute of Technology

    Author : Behrouz Nourozi; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater heat recovery; balanced mechanical ventilation; defrosting reduction; heat recovery efficiency; thermal load shifting; renewables; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. READ MORE

    Abstract : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. READ MORE

  4. 4. On the thermal inertia and time constant of single-family houses

    University dissertation from Linköping : Linköpings universitet

    Author : Johan Hedbrant; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric heating;

    Abstract : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. READ MORE

  5. 5. The impact of wind power variability on the least-cost dispatch of units in the electricity generation system

    University dissertation from Linköping : Linköpings universitet

    Author : Lisa Göransson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; intermittency; wind-thermal system; variability; cycling costs; electricity generation system; dispatch modeling; variation management;

    Abstract : This thesis investigates the dynamics of electricity generation systems that involve high levels of wind power. Methods to account for wind power variability in electricity-dispatch models are explored, and the impact of wind power variability on the optimal output of the generation units, so as to meet the system load with the lowest possible cost (economic dispatch), is analyzed for several systems, for both regional and European cases.
