1. 21. Weather data for heat pump system control improvement: analysis of instantaneous and forecasted measurements and evaluation of potential energy savings

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Mattia Monteggia; [2018]
   Nyckelord :heat pump system control; HVAC predictive rule-based control; weather forecast; occupancy behavior; internal gain; ambient temperature; perfect prediction;

   Sammanfattning : The present work deals with a study related to the analysis of weather data for heat pump system control improvement based on both instantaneous and forecasted measurements. In particular, the analysis is firstly focused on the comparison of multiple weather sources for the assessment of weather forecast uncertainties, based on the evaluation of errors in prediction with respect to measured values.

3. 22. Energy mapping of public buildings : A study at Älvkarlebyhus

   Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Författare :Kieran Crowley; [2017]
   Nyckelord :;

   Sammanfattning : The aim of this report is to identify all energy systems in the Skutskärs Vårdcentral and Folktandvården building, Centralgatan 12 building and the Library building to be studied in this report and carry out an investigation on whether the energy systems efficiency may be increased by improving on the elements or factors that affect the energy systems. A model of the buildings energy systems were created in Microsoft excels using the steady state method and modifying it to calculate an average heating session. LÄS MER

4. 23. PVT-panelernas plats i samhället : En vidareutveckling av Evertechs ETX-paneler

   Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :David Åslund; [2017]
   Nyckelord :Solceller; hybrid; pvt-panel; bergväme;

   Sammanfattning : Abstract To prevent that the climate influences reaches critical and irreversible levels in the near future, a change in our energy consumption and our energy sources is required. It will be a combination of multiple system solutions and several types of renewable sources, both at a personal and national levels. LÄS MER

5. 24. Smart window in Sweden : A comparative analysis of an office buildingsimulation model with conventional windows, andelectrochromic windows, based on Miljöbyggnadcertification criteria

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Marcus Waldron; [2017]
   Nyckelord :IDA ICE; Miljöbyggnad; Electrochromic window; Smart window;

   Sammanfattning : The building sector is one of the sectors that consume most energy in Sweden. Sweden aims thereby to reduce energy use in buildings by 20% by 2020 and 50% by 2050. To achieve these goals, more energyefficient buildings must be produced, and more energy-efficient measures must be implemented on existing buildings. LÄS MER

7. 25. Konflikten mellan dagsljus och solvärmelast : I samarbete med Metod arkitekter för projektet Blå Korset

   Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Izabelle Kleinau; [2017]
   Nyckelord :Technology; energy; environmental development; sustainable development; daylight; solar radiation; solar heaty gain; environmental certification; solar shielding; Teknik; energi; miljöutveckling; hållbar utveckling; dagsljus; solinstrålning; solvärmelast; miljöcertifieringar; solavskärmning;

   Sammanfattning : En teknisk undersökning har gjorts i syfte att diskutera konflikten mellan dagsljus ochsolvärmelast i byggnader. I detta arbete studeras konflikten i samarbete med Metod arkitekterför projektet Blå Korset och dess val av solavskärmning som lösning till problemet. LÄS MER
