Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

The voluntary none-financial sustainability report has become a trend within accounting. The environmental issues used to be driven by activists only, but lately it has moved in to the general agenda in many companies. Investors are starting to put more attention to the sustainability reporting as it is considered to add value to the company. There are several standard guidelines to be used when producing a sustainability report, one example is the GRI´s Guidelines that takes the following three dimensions in consideration: economy, environment and social. This Guideline is from an international perspective considered to be of good accounting practice (Ljungdahl 2008).

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Syfte: Syftet med uppsatsen är att beskriva och analysera hur kommunala energibolag resonerar vid val av avskrivningsmetod samt hur kommunala energibolag har förberett sig inför införandet och hur de förhåller sig till implementeringen av komponentavskrivningar.Teorier: De teorier som använts i uppsatsen finner vi vara relevanta och applicerbara utifrån studiens syfte och frågeställningar. Vi har bl.a. använt oss av Burns & Scapens ramverk som ingår i den institutionella teorin, vilket är den teori som studien utgått ifrån.Metod: Studien utgår ifrån den kvalitativa ansatsen med hjälp av semi-strukturerade intervjuer och dokumentgranskning.Empiri: Empirin innefattar intervjuer med 5 kommunala energibolag inkluderande granskning av relevant dokumentation.Slutsatser: Studien har visat att de kommunala energibolagen upplever avskrivningsval som en svårbedömd process som präglas av en inre tröghet på grund av påverkande faktorer och inrotade regler och rutiner. I och med tolkningen och införandet av BFNs regelverk avseende komponentavskrivningar har ett internt motstånd byggts upp på grund av svåra och godtyckliga bedömningar. Detta har bidragit till en spretighet, vilket har påkallat behovet av tydligare rekommendationer och direktiv.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

In the beginning of the 21th century several successful companies filed for bankruptcy. These bankruptcies have been known as large accounting scandals and the largest scandals did Enron and Worldcom stand for. These bankruptcies arose without any warning signal from the auditors about the companies? financial problems and their inability to continue as a going concern. The bankruptcies damaged the reputation of auditors and broad criticism has developed at the auditors? inability to discover companies? financial problems and their unwillingness to reveal a going concern opinion in the audit report.

Companies today are facing more and different kinds of demands from the society and their stakeholders. It is no longer enough to just deliver the products, and not just the quality of the products that matter. The consumers are getting more conscious about the many ways in which companies affect the society and the environment in which we live. The financial sector, that among others includes stakeholders such as insurance companies, banks and fund companies are starting to realise the importance of the non- financial issues that companies are encountering. Analysing the companies sustainability when it comes to social and environmental issues, has become an increasingly important factor when for example choosing companies to invest in.

Bakgrund och problem: IFRS 8, rörelsesegment, är ett resultat av det samarbetsprojekt som pågår mellan de två dominerande normsättarna på redovisningsområdet, International Accounting Standards Board (IASB) och Financial Accounting Standards Board (FASB). IASB offentliggjorde i november år 2006 IFRS 8 som ersatte IAS 14, segmentrapportering, för räkenskapsår från och med 1 januari år 2009. IFRS 8, har till skillnad från IAS 14 ledningsperspektiv på sin segmentrapportering i de finansiella rapporterna, vilket kan bidra till lägre jämförbarhet mellan företagen och högre relevans.Syfte: Syftet med studien är att identifiera skillnaderna mellan IAS 14 och IFRS 8 vad gäller antalet segment, mellan årsredovisningen för år 2008 och första kvartalsrapporten för år 2009. Syftet mer konkret, är att undersöka om företagen i studien har förändrat antalet segment samt om det påverkat jämförbarheten.Metod: Urvalet för studien är de 255 företag som var listade Stockholmsbörsens listor Large Cap, Mid Cap och Small Cap den 9e november 2009. Studiens är en jämförelse på företagens förändring i antal rapporterade segment mellan årsredovisningen år 2008 och första kvartalsrapporten för år 2009.Resultat och slutsatser: Författarna kan inte statistiskt säkerhetsställa att en förändring skett i antalet segment.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

This study deals with sustainability reporting in three governmental and three non-governmental Swedish companies in different industries. With increasing demands from the society regarding company?s CSR - Corporate social responsibility, the perspective of accounting gets broader and covers even non-financial information to meet not only the owners? demands but also others stakeholders' requirements. Sustainability has become an important tool for creating company?s business value and a positive sustainable external image.

The competition for Norway spruce pulp wood in Central Sweden increases, forcing the supply-structure of Holmen to face two important challenges. Firstly, it is of the outmost strategically importance to secure the long-term supply of Norway spruce pulp wood to the industries. Secondly, Holmen desires to increase the obtainable volume of Norway spruce pulp wood. This would enable the company to choose volumes in the lower price-segments and thereby decrease the dependency of costly marginal volumes. As this work shows, one part in managing these challenges could be to lower the quality standards concerning root rot (Heterobasidium annosum). Facts presented in the work shows that: 1. Technically, the TMP-industry of Braviken can handle a much more rotted pulp wood than that used today, although the cost of refinement increases.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.
