1. Puirava, T. (Tiina). Sizing of the renewable energy and waste management solutions for an eco-district:case Maijanlenkki.

Degree: 2018, University of Oulu

Abstract This thesis is made as a part of the RECENT project which aims to increase energy independency in rural areas by providing sustainable solutions to them. The aim of this thesis is to design an eco-district for the municipality of Muhos utilizing sustainable energy and other environmental friendly solutions. The main focus was to study household energy consumptions, compile consumption profile and size solar photovoltaic (PV) system for the area by modelling. At the start of the thesis a survey was held during a builder fair to clarify the interest of people towards eco-district and sustainable solutions. Theoretical part of this thesis included examining existing ecological settlements and their main features, different real estate company forms from legal and suitability points of view and typical energy issues related to buildings. Ecological settlements were found usually to have low energy consumption, renewable energy, recycling, good-quality materials and communality. Importance of careful planning and taking potential challenges into account were considered. Four different kinds of real estate company forms were examined; housing company, joint-stock property company, right of occupancy organization and co-operative housing association. Energy issues discussed included energy saving, ecological living habits, energy efficient appliances, heating technologies, electricity production with solar PV panels, energy storage and house automation. Practical part was started by choosing basic structures for the case. The area was chosen from town plan of Päivänpaisteenmaa in cooperation with the Muhos municipality’s representatives. The suitable area was chosen to be road Maijanlenkki because of its shape and surroundings. Plots, houses and common service building were planned for the area so that energy technologies could be sized in the next phase. Community, technical and northern aspects were taken into consideration. Additional solutions favored by people in the questionnaire were applied to this thesis which were common waste management system, composting and recharge point for electric cars. Energy demands in space heating, water heating and electricity were calculated for different types of households and consumption profile for the case area was compiled from actual measured data. Ground source heat pump (GSHP) system including borehole was sized based on the calculated energy demands. Different size solar PV systems were modelled by 3D modelling program SketchUp and an add-on Skelion. Actual weather data from Sotkamo and Oulu was used and results for oversized, optimal and individual scenarios were evaluated to choose a suitable solar PV solution for the case. Common waste management system was sized to the area from actual measured waste amounts. Finally economical calculations were done for the main…
