Energiaspekter på gestaltning : fallstudie Energihuset i Uppsala
This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.

Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.
Strömsparande arkitektur för inbyggnadslinux
The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..
Hållbarhetsredovisning ? för vem och vad? : Hur ser analytiker, konsulter och förvaltare på hållbarhetsredovisning?
AbstractTitle:Sustainability reporting- For whom and what? What is the opinion of analysts, consultants and fund managers on sustainability reporting?Level:Bachelor thesis in business administration, 15 university creditsAuthors:Nils Johansson and Hannes ThomasfolkSupervisor:Sarah PhilipsonDate:20140108Keywords:Sustainability reporting, value relevance, stakeholder theory, signaling theory.Purpose:The purpose of this paper is to study how different professional groups in the Swedish financial market in 2013 use sustainability reporting and explore how professional groups look at the future development of sustainability reporting.Limitations:The study focuses only on organizations that are members of SWESIF.Method:In this study we chose a multiple case study design, inspired by well grounded theory. The study's empirical data was obtained through ten semi-structured interviews with analysts, consultants and fund managers.Results and conclusions:It was revealed by the study that companies producing a sustainability report demonstrates transparency and are perceived as a company that is aware of risk, both economic risks as well as external risks. The study also shows that among the study's respondents, there is a strong belief that sustainable business in the long term is a good investment. The study also indicates that this is no concrete evidence of an association between the use of sustainability reporting and either increased or decreased profitability.

Solenergisystem i Kista Galleria
Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.

Implementering och kommunikation av ekologisk h?llbarhet. En fallstudie om utmaningar och strategier i fordonsindustrin
The purpose of the study is to explore the internal implementation and communication of ecological sustainability within an organization and to identify obstacles and challenges that may arise. To address the study's purpose and research questions, a qualitative methodology
and semi-structured interviews were used. Respondents were selected from two different units within a large global organization operating in the automotive industry. The study's findings indicate that the organization's sustainability efforts are extensive and integrated
across several departments. It is also evident that sustainability initiatives are primarily driven by upper management within the organization, although there is room for lower hierarchical levels to provide some feedback.
Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext
Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.
Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav
The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Energideklarationen : Uppfyller energideklarationen sitt syfte?
The Energy Performance Certification in Sweden was developed as a tool to achieve the Government's target to reduce Sweden's energy consumption by 20 percent by 2020. The Energy Performance Certificate has previously received some criticism for not fulfilling its purpose. Questions that formed the basis for this report is how the energy performance certification provides support to buyers of single-family houses and if the energy performance improved in terms of reliability. The report begins with a background description that describes how the energy declaration works and some of the findings of previous evaluations and surveys. A survey to investigate the broker's position to energy performance have been conducted as well as interviews with buyers and sellers of houses. An investigation whether the energy performance can vary between different calculation programs, depending on various assumptions made by the energy declarant, has been made.Brokers and sellers have proved negative attitudes towards energy performance, particularly brokers.
Skillnader i synen på granskning av hållbarhetsredovisningar : nationella och kulturella olikheter
Presently environmental and ethical matters are in the centre of attention and companies producing sustainability reports have become more common. It has also started to become more and more ordinary to assure these sustainability reports by an external part. However, the amount of assured sustainability reports differs a lot between different countries.There can be several reasons for why the companies chose to get the sustainability report assured. Previous studies state that the choice to produce sustainability reports can be re-lated to theories like the legitimacy theory, stakeholder theory and the agent theory. Other aspects that can affect the decision to construct a sustainability report can according to prior studies be different company characteristics and the national culture in the country in which the company is operating.
