    Abstract : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.

  3. 3. Optimisation of Local and National Energy Systems : Development and Use of the MODEST Model

    Author : Dag Henning; Carl-Johan Fogelholm; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Energy may be supplied by a multitude of components. Computer simulation helps in finding a beneficial system design. The energy-system optimisation model MODEST has been developed, and it has been applied to municipal, regional, and national energy systems. READ MORE

  4. 4. CO2 capture from oxy-fuel combustion power plants

    Author : Yukun Hu; Jinyue Yan; Erik Dahlquist; Mats Westermark; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; oxy-fuel combustion; flue gas recycle; evaporative gas turbine; techno- economic evaluation;

    Abstract : To mitigate the global greenhouse gases (GHGs) emissions, carbon dioxide (CO2) capture and storage (CCS) has the potential to play a significant role for reaching mitigation target. Oxy-fuel combustion is a promising technology for CO2 capture in power plants. READ MORE
