    Sammanfattning : Modern energy saving technologies are become increasingly mature, easier to implement and financially profitable. Both the European Union and the Swedish government have directives with goals regarding energy savings for the year 2020 and 2030. LÄS MER

  2. 2. Optimization and Control of Heat Loads in Buildings

    Master-uppsats, KTH/Energiteknik

    Författare :Matilda Stendahl; [2018]
    Nyckelord :district heating; peak shaving; capacity control; smart heating; demand side management; fjärrvärme; toppkapning; effektstyrning; värmestyrning; efterfrågesidahantering;

    Sammanfattning : District heating is considered an environmentally friendly, efficient and cost-effective way of providingheat to buildings but even so, the industry will be facing several challenges in the upcoming years. Acombination of higher operating costs, growing demand, competition from alternative heatingtechnologies, national and international climate and energy goals and the need for transparency towardscustomers places high requirements on many thermal energy suppliers.

  3. 3. 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

  4. 4. 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.

  5. 5. 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; 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
