1. 1. Technical performance modelling and optimization of PVT collectors in GSHP integration

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

   Author : Marin Courcault; [2023]
   Keywords : PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

   Abstract : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. READ MORE

3. 2. Sustainable Urban Energy Transition for the City of Bitola, North Macedonia : A City-Scale Urban Building Energy Model

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

   Author : Emilie Andersson; Hillevi Höijer; [2023]
   Keywords : Urban building energy model; UBEM; Urban energy simulation; Urban energy transition; City Energy Analyst; CEA; Bitola; North Macedonia; Byggnadsmodellering på stadsnivå; Stadsenergimodellering; Stadsenergiomställning; Urban Building Energy Model; City Energy Analyst; CEA; Energisystemmodell; Bitola; Nordmakedonien;

   Abstract : Cities play a crucial role in sustainable energy system transformation. Urban energy systems account for 75% of global primary energy use, and 70% of global greenhouse gas (GHG) emissions (IEA, 2021). READ MORE

4. 3. Energy communities' place in society : Energy communities' economical sustainability and possibilities to create benefits for a local power grid

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Sandra Boström; Felicia Sillén; Melker Nilsson; Karl Simander; [2023]
   Keywords : Energy community; tariffs; power grid;

   Abstract : To hasten the transition to reliance on renewable energy sources, energy communities could be part of the solution. An energy community, in this report, is defined as several residential houses that come together and share a virtual fuse for a bigger tariff subscription to the energy grid. READ MORE

5. 4. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

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

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

6. 5. Performance Analysis of CO2 Heat Pumps in Different Applications

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