Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar
The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.
Testmetodik för vintertestning av el- och hybridfordon
With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

Arbetets intention är istället att bostäderna skall integreras i platsens stora värden och därmed göra platsen mer tillgänglig för flera av stadens invånare..
Fjärrstyrd undervattensfarkost
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Hållbara energilösningar för Sala silvergruva : En studie av energisystemet och effektiviseringsmöjligheter
Sala Silvergruva AB är ett av många företag som just nu kämpar med höga energi-kostnader. Denna rapport undersöker vilka möjligheter det finns att skapa ett hållbart energisystem i Sala Silvergruva med avseende på ekonomi, miljö samt sociala aspekter. Rapporten undersöker nio tekniker; vindkraft, vattenkraft, solfångare, solceller, pelletspannor, värmepumpar, effektivisering samt lagring av värme från växthus respektive fjärrvärme. Dessa analyseras var för sig med utgångspunkt i tio krav som speglar hållbarhetsaspekterna. I samband med analysen ges rekommendationer angående investering i respektive energilösning. Rapporten mynnar ut i en resultatskarta där det tydligt framgår vilka krav de olika teknikerna uppfyller. Den följande diskussionen leder fram till en slutsats som presenterar vilka åtgärder som bör vidtas i syfte att skapa ett uthålligt energisystem för Sala Silvergruva AB. Pelletspannor och värmepumpar visar sig i nuläget vara de mest uthålliga tekniklösningarna.
Assessment methods for corporateresponsibility on the fashion scene : a case study of Hennes & Mauritz, Lindex, Kappahl and MQ
Assessing the outcome of corporate responsibility is often argued to be complicated due to long-term effects and qualitative aspects. Epstein (2008, p.261) establishes that: ?Though many think that sustainability is too difficult to measure, companies have found that unless the impacts are measured, they are commonly ignored in the resource allocation process?. Corporate responsibility is often referred to as a business case, i.e., that social and environmental concern add value to the business (Heikkurinen, 2010; Porter & van der Linde, 1995). Hence, for corporate responsibility to be a business case a strategy, corporate structure and systems, programmes and actions linked to performance measures need to be in place to assess the outcome; environmental, social as well as financial.

Examining the social component of sustainable forest management in Prince Albert and Vilhelmina Model Forests
Due to the forest industry downsizing, many communities in rural forest regions in Canada
and Sweden are facing problems to survive. In order to create community sustainability,
resilience and well-being in remote forest regions, the view on the forest resources has
shifted towards multiple use, through the concept of sustainable forest management (SFM).
Beside the economic and ecological elements of sustainability, the social forest values are
needed, contributing to the human well-being, local participation, stakeholder collaboration,
human rights and cultural connection.
In this thesis the embodiment of the social component of SFM within Prince Albert Model
Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners
and facing similar challenges as rural boreal forest regions, the two model forests are compared
through analysis of projects and activities, conducted interviews and organization
documents.
Looking at projects mentioned as successful by the interviewees, they all have elements
from the social values of SFM. The direction can be explained by the introduction of the
Forest Communities Program in Canada, demanding the Model Forests to work towards
community stability and resilience, the Model Forest organization concept itself and the
way global focus are increasing around social forest values. In the future, it may be important
that the role of the MFs enable some kind of political authorization and legitimacy in
order to improve conflict solving and indigenous rights equality.
Corporate Social Responsibility - A case study about how to improve a company?s CSR work
Background: Since the start of the twenty-first century it has become very important for companies to act in a responsible manner, in guides of CSR. The idea is that companies have more responsibilities than to achieve a higher profit for their shareholders. They should also care about the society and act in a responsible way.Problem discussion: Problems concerning CSR are that the internal part of the sustainability work has not encountered the same level as the external part of the sustainability work. Companies are today struggling with implementing CSR into their business strategies.Research questions:1. What does a company has to consider when working with CSR? 2. How can management control systems help the implementation of CSR into the organisation?Purpose: The purpose of this thesis is to examine what a company has to consider when working with CSR and how management control systems can help the implementation of CSR into the organisation.
Byggnadens andra skepnad : En anpassning för att möta samhällets behov och krav
Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.
Stommaterial för villor - trä eller betong?
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
