  5. 13. 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.

  6. 14. Operability Considerations for Retrofit Design of Industrial Process Energy Systems

    Author : Sofie Marton; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interviews; Steam System; Heat integration; Implementation; Operability; Non-energy benefits;

    Abstract : Energy efficiency is crucial to reduce fuel usage and related emissions in industry.  In energy-intensive process industry, the use of heat accounts for a large share of the total energy use and a reduction of the heating and cooling demand is thus important for decreasing energy use.

  7. 15. Building Retrofit using Vacuum Insulation Panels: Hygrothermal Performance and Durability

    Author : Pär Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory; retrofitting; interior insulation; listed building; field study; exterior wall; brick wall; numerical simulation; wooden beam ends; measurement; vacuum insulation panel; transient plane heat source; exterior insulation;

    Abstract : Many old buildings have unsatisfactory thermal performance compared to the standards of today. One way to increase the thermal performance is to add thermal insulation to the building envelope. However, many old buildings are listed and considered to be valuable for historical and esthetic reasons. READ MORE
