  2. 6. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

    Author : Ricardo Bernardo; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar domestic hot water; retrofitting; single family electrically heated houses; high solar fraction; photovoltaic thermal concentrating hybrids; PVT; parabolic reflectors; CPC thermal collector.;

    Abstract : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. READ MORE

  4. 7. Wetting and drying of aerogel-based coating mortars in Swedish climates

    Author : Ali Naman Karim; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; runoff; Aerogel; retrofitting; coating mortar; wetting; drying; wind-driven rain; render;

    Abstract : Aerogel-based coating mortars (ACMs) have emerged as energy-efficient wall finishes with thermal conductivities of 30–50 mW/(m∙K). These coating mortars represent a promising alternative to traditional thermal insulation materials for retrofitting uninsulated building envelopes particularly in culturally significant structures.

  5. 8. Improvement of Thermal Comfort in Buildings through Passive Design

    Author : Marcelino Januário Rodrigues; Byggnadskonstruktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Sustainability; Energy Efficiency; Passive Design; Orientation; Shading; Ventilation; Materials; Temperatures; Thermal Comfort; Simulations; Retrofitting; Hot Humid Regions.;

    Abstract : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. READ MORE

  6. 9. Promotion of sustainable renovation in the built environment : An early stage techno-economic approach

    Author : Navid Gohardani; Folke Björk; Bo-Göran Hellers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refurbishment; retrofitting; renovation; energy consumption; Vacuum Insulation Panels; ACES;

    Abstract : According to the Swedish Government's set targets for energy use and environmental quality imposed by the European Union, the total energy per heated unit area in residential and commercial buildings will have to be decreased by 20% in 2020 and 50% by 2050 in relation to the annual consumption of 1995. The building sector should additionally be completely independent of fossil fuels for energy usage, with the increasing sector of renewable energy continuously growing until 2020. READ MORE

  7. 10. 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
