21. Evaluation of decentralized ventilation system with heat recovery
M1-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system.

22. Prestandaanalys vid rengöring av värmeväxlare i fjärrvärmecentral för småhus : Fallstudie på rengöring av en värmeväxlare för småhus
Kandidat-uppsats, Högskolan Dalarna/EnergiteknikSammanfattning : Försmutsning av plattvärmeväxlare i fjärrvärmecentraler minskar avkylningen av det cirkulerande vattnet i fjärrvärmenätet. Detta ökar behovet av värmeproduktion i fjärrvärmeverket vilket medför ökade utsläpp av växthusgaser. Mängden försmutsning beror på vattnets kvalitet och material i systemet. LÄS MER
23. Development of evaluation tools as an approach to pre-design district energy systems : Qualitative modeling and performance simulation using OpenModelica
Master-uppsats, KTH/EnergiteknikSammanfattning : Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. LÄS MER
24. A hybrid low - temperature heating system in geothermal retrofitting for public buildings in the Mediterranean climate
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : More than 50 % of EU’s yearly energy demand is spent on heating and cooling systems with which most of its source is generated from non-renewable fossil fuel [1]. Furthermore, half of the EU buildings are heated with a non-efficient boiler of about 60% or less efficiency [1]. LÄS MER
25. The impact of climate change on the energy demand and indoor climate of an apartment building in Stockholm
Master-uppsats, KTH/Hållbara byggnaderSammanfattning : With an increasing global concern about climate change, an important topic for the building industry is how climate change will affect the energy behaviour of buildings and their indoor thermal comfort levels. Many residential buildings do not fulfil the healthy requirements regarding indoor temperatures due to poor design even with the current climate conditions. LÄS MER
