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

    Author : Matilda Hallin; [2023]
    Keywords : ;

    Abstract : This study systematically categorizes energy efficiency measures in buildings and evaluates their effectiveness in terms of energy savings, CO2e emissions reduction, and cost-effectiveness. It also explores the potential correlations between measure effectiveness and various building characteristics. READ MORE

  3. 8. Feasibility study of evaporative cooling and toilet flushing using rainwater in a public building

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

    Author : Claudia Reig Moril; [2023]
    Keywords : Rainwater; Evaporative cooling; Toilet flushing; Energy; Water; Feasibility.; Regnvatten; Evaporativ kyla; Toalettspolning; Energi; Vatten; Genomförbarhet.;

    Abstract : The project "Feasibility of evaporative cooling and toilet flushing using rainwater in a public building" combines rainwater harvesting with the evaporative cooling technology and toilet flushing and explores the practicality and viability of implementing this innovative system in the city of Gothenburg, Sweden. This study comprehensively investigates various aspects related to water and energy, and the entire system is computationally modelled using the Equation Engineering Solver (EES) software. READ MORE

  4. 9. Design Guidelines of A Low Power Communication Protocol for Zero Energy Devices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiayue Zhang; [2023]
    Keywords : Energy efficient communication protocol; sensor data transfer; zero energy devices; battery-less; energy harvesting; Energieffektiv kommunikationsprotokoll; sensordatöverföring; “zero” energienheter; batterifria; energy harvesting;

    Abstract : Lågströmskommunikationsprotokoll såsom 6LoWPAN har använts i stor utsträckning för applikationer som kräver mindre energiförbrukning för trådlös kommunikation på korta avstånd, exempelvis IoT-enheter. Eftersom antalet sådana enheter ökar blir det allt viktigare att överväga ambient energy harvesting som en energikälla för att driva sådana enheter. READ MORE

  5. 10. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Qinglong He; [2022]
    Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

    Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE
