  1. 26. Study of the ventilation system in a warehouse and a cooking school : Impact of the use of a heat exchanger system and a more optimised operating schedule

    Magister-uppsats, Högskolan i Gävle/Energisystem

    Författare :Javier Iglesias Estellés; [2018]
    Nyckelord :Ventilation; warehouse; cooking school; efficiency measures; heat recovery ventilation; demand controlled ventilation; energy audit; Gävle.;

    Sammanfattning : The motivation of this project is found on the past trend of growing greenhouse gases emissions and, also growing, energy use over the world that still remains. This trend overlaps with a more recent increase in the awareness regarding the effects of human activities towards the Earth ecosystems. LÄS MER

  3. 27. Smart Buildings: ICT as a driving energy-efficient solution for retrofitting of existing buildings

    Master-uppsats, KTH/Energiteknik

    Författare :Giuseppe Sgrò; [2018]
    Nyckelord :;

    Sammanfattning : It is widely recognized how energy efficiency can contribute to decreasing GHG emissions, especially in the building sector, where buildings will play an increasingly important role for the future energy system, being both the largest energy consumers and becoming one of the greatest producers of renewable energy. In this new energy context, where renewable sources will be the main supplier for the production of electricity, there will be a growing need for dynamic control as well as intelligent and interconnected systems, which will lead to the creation of a new ICT architecture based on the interaction between Smart Buildings and Smart Grid, where buildings will take the role of proactive participants in the smart electricity network, facilitating the reduction of energy consumption and GHG emissions as well as other societal benefits.

  4. 28. ME/CFS - livskvalitet, aktivitetskompetens och värdering av aktivitet : En enkätstudie om myalgisk encefalomyelit/kroniskt trötthetssyndrom (ME/CFS)

    Kandidat-uppsats, Högskolan i Jönköping/HHJ, Avd. för rehabilitering

    Författare :Sascha Carlsson; Charlotte Bernung; [2018]
    Nyckelord :Ansträngningsutlöst utmattning; arbetsterapi; Min Mening; SF-36; vardagsaktivitet.;

    Sammanfattning : Bakgrund och syfte: ME/CFS påverkar i hög grad aktivitetsförmågan, med många olika kroppsliga symptom. Även små ansträngningar kan ge kraftig försämring. För fungerande vardag krävs planering och prioritering av aktiviteter, vilket förutsätter att den drabbade vet vilken ansträngning som åtgår och vad som är viktigast. LÄS MER

  5. 29. Network Densification and Energy Efficiency

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Sammanfattning : The galloping pace of development in the field of wireless communication has left the world astounded over the last decade. But this has also led to a wild and inexcusable extravagant expenditure of energy. LÄS MER

  7. 30. Evaluation of an Energy System for multi-family houses with Combination of Exhaust Air Heat Pump and PV : Case Study: Demonstration Building of The EU Energy Matching Project, Sweden-Ludvika

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Mohammad Azad; [2018]
    Nyckelord :EnergyMathcing project; Energy system; Novel heating technologies; On-site Renewable Energy; Low temperature heating system; combined solar technologies and heat pump; photovoltaic and exhaust air heat pump; nearly zero energy buildings; simulation of building and energy system;

    Sammanfattning : This thesis investigated application of the heat recovery ventilation using an exhaust air heat pump and a roof top photovoltaic (PV) system for a group of three multi-family houses located in Ludvika, Sunnansjö. The buildings in the existing condition have mechanical ventilation and a centralized heating system consists of a pellet boiler as the main source and an oil boiler as back up. LÄS MER
