  1. 1. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

  3. 2. PV self-consumption: Regression models and data visualization

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Martos Tóth; [2022]
    Keywords : Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

    Abstract : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. READ MORE

  4. 3. Energy Renovation: A case study of a multi-family house built during the Million program in Djursholm

    University essay from KTH/Energiteknik

    Author : Adiltogtokh Bold; [2022]
    Keywords : Energy Renovation; Refurbishment; Energy Efficiency Measure; Direct-electric Heating; Multi-family House; Energirenovering; Renovering; Energieffektiviseringsåtgärd; Direktverkande El; Flerfamiljhus;

    Abstract : Large share of Swedish building stock were built during 1940-1980 when people were not fully aware of the energy efficiency concept. Majority of the buildings that made energy declaration are in energy class E-G, which are considered as high energy consumption buildings with low energy performance, and only few buildings meet the Swedish requirements for near zero energy buildings which are in energy class A-C.

  5. 4. Development of a Simulation Model for Combined PVT and Ground Source Heat Pump Systems : A TRNSYS Model Created for Commercial Use

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : HANNA OLAUSSON; EMMA WERNIUS; [2021]
    Keywords : Electrify everything; Solar assisted heat pump; Solar Energy; TRNSYS; Elektrifiera allt; solassisterad värmepump; Solenergi; TRNSYS;

    Abstract : The Swedish government has set a target of a 100% renewable electricity system by 2040. To reach this goal, many actions have to be undertaken. Electrification of buildings is one action to be undertaken as the residential sector accounts for a large share of greenhouse gas emissions, where the most energy efficient method is to use heat pumps.

  6. 5. Effect of Heatwaves on the Cooling Demand of Austrian Residential Buildings

    University essay from KTH/Energiteknik

    Author : Apoorv Mukati; [2021]
    Keywords : ;

    Abstract : Buildings account for 40% of total energy consumption and 36% of CO2 emissions in the European Union. In 2019, households, or the residential sector, represented 26.3 % of final energy consumption in the EU out of which space cooling represented 0.4% energy consumption (Eurostat, 2021). READ MORE
