  2. 1. A Policy Analytical Approach of Assessing Energy Efficiency Standards and Labeling for Appliances

    Author : Lei Zeng; Jinyue Yan; Siaw Kiang Chou; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Efficiency Standards; Minimum Energy Performance Standard MEPS ; Energy Labels; Energy Efficiency Labels; Eco-Labels; Appliance Energy; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : China is the world’s largest producer and consumer of household appliances, lighting and commercial equipment. China first adopted Minimum Energy Performance Standards (MEPS) in 1989. READ MORE

  4. 2. Low-hanging fruit : Measures to reduce fruit and vegetable waste at supermarkets

    Author : Lisa Mattsson; Helén Williams; Casper Boks; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food waste; retail; supermarket; fruit and vegetable; causes; measures; employees; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : More than 30 percent of the food produced for human consumption is lost or wasted globally. This leads to a significant environmental impact in terms of inefficient use of natural resources, as well as economic costs and social and moral issues. READ MORE

  5. 3. Emissions from realistic operation of residential wood pellets heating systems

    Author : Kaung Myat Win; Rebei Bel Fdhila; Tomas Persson; Erik Dahlquist; Henrik Thunman; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood pellet; Heating; Combustion; boiler; stove; emissions; particulate matter; Energy- and Environmental Engineering; energi- och miljöteknik; SWX-Energi; Integrerade system för sol och biobränsle;

    Abstract : Emissions from residential combustion appliances vary significantly depending on the firing behaviours and combustion conditions, in addition to combustion technologies and fuel quality. Although wood pellet combustion in residential heating boilers is efficient, the combustion conditions during start-up and stop phases are not optimal and produce significantly high emissions such as carbon monoxide and hydrocarbon from incomplete combustion.

  6. 4. Combined solar and pellet heating systems : Studies of energy use and CO-emissions

    Author : Frank Fiedler; Högskolan Dalarna; []
    Keywords : Pellet and solar heating systems; CO-emissioins;

    Abstract : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. READ MORE
