    Författare :Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Sammanfattning : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. LÄS MER

  3. 12. Exploring barriers to energy efficiency in supermarkets

    Författare :Ulla Lindberg; MariAnne Karlsson; Högskolan i Borås; []
    Nyckelord :retail; servicescape; foodscape; chilled groceries; energy efficiency; barriers; refrigerated display cabinets; consumer behaviors; consumer perceptions; Resource Recovery; Resursåtervinning;

    Sammanfattning : Energy efficiency activities in sections of grocery stores for chilled groceries are subject to particular challenges as this is a complex indoor environment given that the goal of store owners is to offer consumers chilled groceries of high quality in a comfortable environment while at the same time trying to reduce energy use. Consequently, it is important to maintain the right temperature in the right place and to be aware of the consumers’ shopping situation. LÄS MER

  4. 13. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

    Författare :Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Per Engstrand; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER

  5. 14. Energy Efficiency Versus Gains in Consumer Amenities

    Författare :Frances Sprei; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy efficiency; residential buildings; service features; Sweden; passenger cars; fuel consumption; downsizing; technological development;

    Sammanfattning : This thesis, consisting of five papers, addresses the question of what share of technological development results in increased energy efficiency rather than offsetting improved consumer services in the form of gains in consumer amenities? In the first paper economic and organizational explanations are given for stagnating energy efficiency trends in the Swedish residential building sector. The results show that changes in energy prices to a large extent explain the observed stagnation. LÄS MER

  7. 15. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage

    Författare :Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Rob M.P. Goverde; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver Advisory System; Catenary-free Operation; Electric Train; Electric Multiple Unit; Battery; Energy Efficiency; Energy Storage; Speed Profile Optimization; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. LÄS MER
