Smart Control : En reaktion på EU:s ekodesignkrav
The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

Produktionseffektivisering : - Få processens samtliga aktörer att sträva mot samma mål genom ökat samarbete och delaktighet i produktionens olika skeenden.
The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.

Energieffektivisering i flerbostadshus : En analys av ägarformens påverkan på arbetsprocessoch resultat
In Sweden the residential and commercial sector is a major user of energy, why the Swedish government has set a specific goal to half the energy usage in buildings by 2050, compared to 1995. The Swedish Energy Agency has therefore started the campaign ?Halvera Mera? to encourage demonstration projects that will show how to renovate in an energy efficient way, and in doing so prove that it is possible to reduce a building?s energy usage by half and still make a profit. These projects are intended to serve as good examples and give inspiration to residential owners to perform energy efficient renovations. To make sure that these projects serve their purpose, it is important to know what will inspire and what will impede a residential owner to invest in energy Efficiency improvements.
Utvärdering av mjukvara inom processindustrin
This study is an evaluation of the runtime watch function in a OEE software, knownas ProTAK. OEE stands for Overall Equipment Effectiveness, it?s a way to measurethe factories process efficiency. The runtimewatch function allows the user to setup and monitor certain critical objects that are of importance for the pulp and paper process at the mill. The data from the runtimewatch can be correlated towards the suppliers specification for the components.
Lean production ? I en traditionellt styrd organisation
Lean production härstammar från företaget Toyota och Taiichi Ohno?s begrepp ToyotaProduction System. Metoden är idag ett dominerande styrmedel bland organisationer. Därmedhar konceptet implementerats i allt fler västerländska resultatstyrda organisationer, varsparametrar för kontroll skiljer sig mot de lean production utgår från. Dess innebörd sträckersig över stora delar av en organisation, vilket bidrar till begreppets komplexitet.
Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning
Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.

Hur bra är kulturskolans lokaler? : En undersökning om vad musik- och kulturskolans lärare anser om sina undervisningslokaler
The purpose of this dissertation is to examine how teachers in the municipal Music schools Schools of arts (kulturskolor) estimate the quality of their teaching rooms, which factors that are significant for their opinion, and if they have experienced any tendencies of improvement in the quality of their teaching rooms. The examination is built on a questionnaire, which was sent to a number of music- and ?culture schools? in Sweden. From the answers you can read that the majority (66%) of the teachers are satisfied with their teaching rooms, even if a relatively large part (33%) seems to be unsatisfied. The single factor that are of most importance for their opinion are how much of their teaching they spend in rooms that doesn?t belong to the music- or ?culture school? and also are used for other kinds of education.
Struktur och styrning med balanced scorecard som styrverktyg : En studie inom Västra Götalandsregionen
BackgroundThere are different organizational structures and control and it has been proved difficult to find a combination between these that leads to goal congruence and improved efficiency. An organization can be structured according to hierarchical levels and the decision making can be either centralized or decentralized. Organizational control can be classified according to the amount of rules and balanced scorecard can be used to weld together the structure with the control.PurposeThe purpose is to create an understanding of how two types of structures and control in an organization appears and also to investigate how these differ from one another concerning the balanced scorecard as a control system. We will also investigate how the variables goal congruence and efficiency are affected by the implementation of the balanced scorecard.MethodTo answer the purpose of this thesis we have mainly used the qualitative method since we have studied two organizations thoroughly through interviews on different levels of the organization. The study also has some quantitative elements since we wanted to get a more truthful picture of the organizations.
