Utveckling av modell för dokumentation och elkvalitetsberäkningar
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with …
Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar …
Utveckling, implementering och utvärdering av visualiseringsverktyg för minskad elanvändning
This thesis examines the effects of electricity visualization in an office building. The subject was investigated through the creation of a web based visualization tool that was made accessible to the about 1500 employees in a large office building. The visualization was …
En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030
Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased …
… the changes on the electrical market, isinteresting. The biggest part of the electricity that is produced in Sweden comes from a fewcompanies on the market. Two types of produced electricity dominate the market. These areelectricity made from nuclear power and electricity made …
… of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer. The company Minesto has developed a technology that is called Deep Green …
… use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted …

… profitable, while the NPV is a more accurate method. CHP plants produce both electricity and heat for consumption. They have a high efficiency between 80-90%. Previous studies show that Sweden is in a situation where they need to install more CHP to expand the district heating …
… calculation is sensitive even to small changes. Inflation, interest rate, electricity price and energy certificate price can all vary a good deal but as it is almost impossible to predict the development of these factors, the inflation, interest rate and energy certificate price …
… by the system. Solar collectors generate heat, while solar cells generate electricity.Analysis of the different systems shows that solar collectors can supply the entire domestic hot water need, during the summer, in the Royal Seaport. While the electricity from the solar cells …
The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue …
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important …
En undersökning av huruvida solceller är ett fördelaktigt energisystem med avseende på tekniska och ekonomiska aspekter
… that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed. Furthermore, a study about photovoltaic cells has been done. The purpose of the study is to decide whether photovoltaic cells are …
En fallstudie på SSAB EMEA i Borlänge
… cooling, which may increase the need for waste heat in the summer and in-house electricity production, which can accommodate some of the steel company's electricity need. A few threats to a continued use of waste heat have also been identified, which the first consists of …
