Kan det sänka bränsleförbrukning och emissioner?
Denna studie avser att ta reda på om någon förändrad effekt kan fås gällande bränsleförbrukning och emissioner då dieselolja strömmar igenom ett magnetiskt fält innan det förbränns i en dieselmotor som driver en generator. Utrustningen som ger upphov till magnetfältet har …
En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
… entails. The results also show the relatively large differences in energy consumption in each case depending on whether the construction has or lacks insulation. Despite the large investment costs estimated payback period for the investment based on a 8000 m 2 surface with an …
… When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating …
… is made. Primarily the photovoltaic system is sized based on the electricity consumption in the buildings. Furthermore an assessment is made whether or not the photovoltaic system is a profitable investment. Lastly a comparison between the output of the analysis and the main …
… on the island Utö in Stockholm’s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ”Skärgårdsstiftelsen” (The Archipelago Foundation) and is a part of the larger EU-project ”Green Islands”. A model for …
… the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that’s been recorded from …
The conflict between conservation requirements and additional insulation
… between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies. The question is whether in practice it is no conflict between conservation requirements and additional insulation of the building envelope and what it …
… energy requirements in public procurement as a tool for reducing energy consumption in the building and plant sectors is therefor an opportunity that operators can take advantage of. The aim of this thesis was to map the energy requirements in procurement that operators in the …
Norra Djurgårdsstaden i samarbete med Grontmij AB
Detta examensarbete har genomförts i samarbete med Grontmij AB och är ämnat att ta fram tre olika förslag på byggnader med samma utformning men uppförda med olika material i klimatskal och stomme, för att jämföra dess energiförbrukning och slutligen analysera koldioxidutsläppen …
En studie om hur ett utbildningsmaterial som integrerar hållbar utveckling i matematikundervisningen kan utformas
… poverty can be investigated using mathematics andby linking those problems to consumptions the students can question theirown role as consumers.
… in Forsmark together produces approximately one-sixth of Sweden’s electricity consumption each year.The background of this study is that a large number of requests come to the purchasing department with incomplete information. Usually it is in the description of what is to be …
… an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor. The program code was made in AVR Studio on a PC and programmed with a AVR one!. The processor was in an AVR Xplain development …
energiflöden och kylning
… that when the cooling system temperature was set to 20 °C or below, the power consumption increased by 1 kW. No upper limit was found. Images taken with an IR-camera indicated that some mixing of hot and cold air takes place near the end of the aisle. Moreover, the difference in …
… primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of …
rekommendationer för ett fortsatt energieffektiviseringsarbete
… give normative recommendations of how the SSS should act to reduce its energy consumption in its locales and provide new insights on how EM, SCM, GSCM and EPI can be applied in effect. The results show that the Swedish Social Service should act in the following areas to control …
