  1. 1. Low-energy buildings energy use, indoor climate and market diffusion

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Johannes Persson; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulations; energy efficiency gap; energy use; indoor climate; low-energy buildings;

    Sammanfattning : Low-energy buildings have, in recent years, gained attention and moved towards a large-scale introduction in the residential sector. During this process, national and international criteria for energy use in buildings have become stricter and the European Union has through the Energy Performance of Buildings Directive imposed on member states to adapt their building regulations for ‘Nearly Zero Energy Buildings’, which by 2021 should be standard for new buildings.

  2. 2. Energy efficiency in Swedish SMEs Exploring barriers, knowledge creation and the role of municipal energy efficiency programs

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Fredrik Backman; Linköpings universitet.; Linköpings universitet.; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy programs; energy efficiency networks; Community of Practice COPs ; barriers; knowledge creation; Policyprogram; energieffektiviseringsnätverk; Community of Practice COP ; barriärer; skapande av kunskap;

    Sammanfattning : The overall aim of this thesis is to analyze how municipalities support small and medium-sized enterprises (SMEs) in their work to improve their energy efficiency. The purpose of this study is to increase the current understanding of how the methods and tools used by municipalities to assist SMEs in improving their energy efficiency influence the end results in terms of achieved energy efficiency, and how knowledge related to energy efficiency is created within SMEs.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fourth generation district heating; TIMES; waste heat; urban planning.; dynamic energy system modelling; MARKAL; passive houses; low-energy buildings; excess heat;

    Sammanfattning : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. LÄS MER

  5. 5. Provisioning Strategies for Transparent Optical Networks Considering Transmission Quality, Security, and Energy Efficiency

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Amornrat Jirattigalachote; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transparent optical networks; routing and wavelength assignment; physical-layer impairments; signal quality; differentiation of services; physical-layer attacks; power equalizers; Greedy Randomized Adaptive Search Procedure GRASP ; green networks; energy awareness; dedicated path protection; shared path protection; survivable WDM networks;

    Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand.
