  2. 21. High-Temperature Cooling Systems for Sustainable Buildings Using Geothermal Energy : Holistic Assessment in the Mediterranean Climate

    Author : Henrikki Pieskä; Johan Silfwerbrand; Adnan Ploskic; Qian Wang; Sture Holmberg; Sasan Sadrizadeh; Ambrose Dodoo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radiant cooling; Geothermal cooling; Energy efficiency; Thermal comfort; Sustainable development; Strålningskylsystem; Geotermisk kyla; Energieffektivitet; Termisk komfort; Hållbar utväckling; Strömnings- och klimatteori; Fluid and Climate Theory;

    Abstract : Sustainable development is increasing its significance in both the scientific and political agenda. In light of this development, the United Nations have published 17 Sustainable development goals (SDGs). READ MORE

  4. 22. Risk Assessment of Hygrothermal Performance - Building Envelope Retrofit

    Author : Simon Pallin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retrofit; Risk; hygrothermal; simulations.; residential; mold; energy savings;

    Abstract : A risk assessment of the hygrothermal performance for a building envelope retrofit investigates possible variations in energy performance, indoor environment quality and moisture safety and elaborates on the risks of exceeding defined acceptance criteria. These risks can be properly determined if including the variability of, by the investigated retrofit, most influencing parameters. READ MORE

  5. 23. Optimum Design of Heat Exchanger Networks in Retrofit Situations

    Author : Annika Carlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

    Abstract : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. READ MORE

  6. 24. Urban Building Energy Modeling for Retrofit Scenarios : Development, Calibration, Validation and Implementation for Swedish Residential Buildings

    Author : Fatemeh Johari; Joakim Widén; Darren Robinson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban building energy modeling; Urban building energy retrofit; Urban energy system; Urban energy planning; Energy performance certificate; Energy efficiency; low-energy cities; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : The necessity for an accelerated transition of urban energy systems and, in particular, the building sector toward energy efficiency and carbon neutrality poses new challenges to planning and retrofitting existing buildings. To cope with these challenges, so-called urban building energy models (UBEMs) have been introduced for quantifying the energy demand in the building sector, identifying the hot spots of energy use and suggesting scenarios for retrofitting the buildings.

  7. 25. Improving Ship Energy Efficiency through a Systems Perspective

    Author : Francesco Baldi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; shipping; exergy analysis; energy systems; energy efficiency; energy analysis; systems analysis;

    Abstract : The last years have been particularly challenging for the shipping industry. Fuel prices have increased to levels only seen during the oil crisis in the 70's, and environmental regulations have grown much stricter than in the past. Climate change, at a global level, is going to become a major threat to society. READ MORE
