Riksbyggen Fastighetsservice is a company whose businesses cope with building construction and related services. The local office of Riksbyggen Fastighetsservice in Gävle has been studied in this project. The local office locates in Näringen 20:4, which was constructed in 1989.   The aim of this project is to make a diagnosis of the current situation; find out the most applicable way of optimizing the operation of the facility in order to reduce the energy consumption, to study costs and possible savings and provide assistance with future energy management.      Firstly, a study of Energy Balance was conducted. The transmission losses was 57761 KWh; mechanical ventilation losses 3855 KWh; hot tap water heat losses 9579 KWh; natural transmission and infiltration 6897 KWh. On the other hand, heat gain from internal heat was 12707 KWh; solar radiation 8521 KWh; and supply heat 56806 KWh.   Secondly, the energy costs have been checked out. 29655 KWh of electricity was consumed in 2008. 5948 KWh was used by 20 fuses electricity and 23707 KWh was for 25 fuses.

Swedish households are getting deeper in debt and house prices keeps on rising. This is what happened in USA and it was one of the major causes of the recent financial crisis. To avoid a similar crisis in Sweden we think one part of the solution is to make sure that those who are students today and soon will get jobs, buy houses, take loans etcetera have necessary knowledge to do so. Students’ saving is an area that almost completely lacked researchers’ attention, and one goal with this thesis is to point out why it’s an important subject and to increase interest among other researchers. We want to give other researcher a foundation to start from, to give an idea of what students saving looks like, so they can continue to explore this important subject. Our research is using theories developed on private saving in American households as a background, and two psychological theories, The theory of planned behavior by Ajzen (1991) and Self-determination theory by Deci and Ryan (2000) as a foundation. This thesis primary focus is on researching students attitude towards saving, students attitude towards stocks and students motivation towards saving. This is researched by distributing a Likert Scale based questionnaire to two groups, business students and technical energy students, a total of 133 students. The answers were collected in two classrooms and all students agreed to fill in the questionnaire leaving us with no non-response bias. The result was very positive and quite surprising. A majority of the students in our study have a positive attitude towards saving, a slightly positive attitude towards stocks and they are motivated to save. Our conclusion is that although the result is positive students saving and students knowledge about saving can be further improved by more education.

Taiwan lack natural and energy resource, need to import 99.3% energy. Due to the traditional high-carbon energy also supply from abroad, its supply will be impacted by international demand and production, price fluctuations, and the international politics. In recent years the international oil price surged upward, business costs were constantly raise. In this study, some small and medium businesses are taken as objects in Kaohsiung, Taiwan. In this investigation, understand the application of energy resource in those businesses, different industries have their attention to other items and differences, it can be seen on those small and medium enterprises in the concept and practice by measuring and computing power consumption. Research Methods: First, to explore the international and domestic energy and policy and the related energy research literature, interview the small and medium enterprises and observe the way of energy usage, and provide the improving solution, questionnaires and field measurements made on those enterprises, to record the response, investment willingness and problem for energy improving, statistical analysis and get the conclusion. The results showed that the prevalence among the small businesses¡¦ waste of energy, there is many invalid lighting, it is the room to improve the installation of reflective shade to effect the lighting, even replace the lamps (T8) to lamps (T5) with reflective shade, then reduce the use of lamps and power, indirectly to reduce the power consumption of air condition. This research also found there is considerable room to improve the light in the refrigerated cabinet. The traditional fluorescent lamps(T8) be used in the refrigerated cabinet. The performance is low and produce high temperature, then the refrigerated cabinet shall expand more power to reach the set temperature, if change those lamps to LED lamps could immediately reduce the loss of electricity bills. Extension of this study, there is a great improvement in the domestic building and enterprises on lighting application, it could reduce a lot of power consumption by detailed observing, detected, and improving engineer to remove lighting waste, and thus achieve carbon reduction targets by 20% of the electricity.

In Taiwan, most of the energy relies on imports due to few natural resources. Further more, scientists estimate that crude oil will be depleted within 40 years. A high cost energy era has arrived. Skyrocketing oil prices have a severe negative impact on the cost structure of the Taiwan Power Company (TPC), which has an estimated deficit of NT$70 billion in 2007. TPC has faced a difficult dilemma: whether to raise the electricity rate or become bankrupt. Eventually, the government has to intervene. The Kyoto Protocol was in effect in February 2005. It is expected that the environmental convention of reducing of CO2 will become an international movement following ISO14000. With every one kilowatt hour of electricity is generated by TPC, 638g of CO2 were produced. The products of made-in-Taiwan will not received international approval and will be boycotted by the International market if the energy efficiency of national enterprise is too low. Air compressor system, which is as important as water and electricity, is popularly used in almost all industries. However, its high energy-consumption and low efficiency system is seldom noticed. The energy cost of air compressor system is about 80% of the total operational cost which includes the electricity costs of all the machinery and lightings. How to improve air compressor efficiency plays an important role in the manufacture¡¦s production cost and its competition against other industries. Facing fierce competition and low profit, the industries must not only continuously innovate and reduce the cost to enhance competition ability for keeping market share, but also increase energy efficiency and reduce the emission of greenhouse gases by the green production method meeting the environmental requirement. The report is the summary of the interviews with many industry leaders who are involved in the air compressor production or the government officials who are in charge of energy-saving promotion. It also combines with the data of actual measurement of the compressor systems to research if the investment willingness of manufacturers is reflected by their operation cost, operation strategy, the risky consideration when facing law and the information getting of compressor energy-saving. The results of the study are: Clarify the main factors which influence the investment willingness to compressor energy-saving. (A) The cost side: The investment willingness is influenced by the cognition of the leaders of manufacturer unit or business owner to compressor system cost. (B) The strategy side: The investment willingness is influenced by the cognition of the leaders of manufacturer unit or business owner to the operation strategy on compressor system. (C) The legal side: The investment willingness is influenced by the cognition of the leaders of manufacturer unit or business owner to the legal affection to business. (D) The information side: The investment willingness is influenced by getting the information of energy-saving of compressor system. Finally, the study proposes a feasible project to the industries and the government officials who promote energy saving.
