Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.

Målet är att identifiera och ge fullständiga åtgärdsförslag på energieffektiviseringar för att minskaenergianvändningen med 25 % och därmed uppnå kraven för Green Building. De fullständigaåtgärdsförslagen ska redovisa ekonomi-, miljö- och hälsoaspekter.För att uppnå syftet med examensarbetet har ett konsekvent tillvägagångssätt använts för attidentifiera potentiella energieffektiviseringar för Smaland Airport. Med hjälp av den bakomliggandestudien ?Energieffektiviseringar Smaland Airport 2010-2011? analyserades kartläggningen avflygplatsens system och processer.Den totala energibesparingen för Smaland Airport uppgår till 646,1 MWh eller 22,04 % vilket fallerinom ramen för Sveriges klimatmål med en sänkt energianvändning på 20 % fram till och med 2020från 2008 års nivå. För att uppnå denna besparing krävs investeringar på 2,78 Mkr.

As a result of directives from EU, with the ambition to reach environmetal goals, The German organisation Passivhaus Institut has defined a passive house. A passive house is a building that is very energy efficient and makes a small impact on the environment. The energy from the inhabitants as well as the appliances & fixtures in the building should equal the energy that is required to heat the building. A Swedish version of the passive house definition has been defined, taking into account the climate conditions and the difference in building regulations.This thesis is a request from Skanska on how it can improve and develop an ongoing passive house project, involving an infant school. The intention of this thesis is to identify difficulties & display potential development areas for infant schools.The method of research conducted is as follows: interviews of clients, ventilation consultant, consultant for heating system and an energy calculation consultant, an inspection of the infant shcool in process, investigation of completed infant schools and a study of relevant literature.From this research it was found that it is difficult for infant schools to pass the criteria for passive houses. The conclusion of this thesis provide several guidelines on how to improve the outcome of existing projects & the steps needed to be taken for future development in this area..

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

This case study explores the question of implementation and steering in a society of governance. As an empirical example, a reform concerning the reception of separated refugee children in Sweden is used. As of the 1st of July 2006 the responsibility for providing housing for separated children lies with the local governments rather than with the Swedish Board of Migration, aiming to improve the children's situation. However, implementing this amendment has turned out to be a harder task than expected. Traditionally, the relationship between state and local actors is seen in terms of state steering or local self-government.

 Dissertation in political science, C-level by Niklas Andersson, Spring Semester 2009. Tutor: Arne Larsson?The Treaty of Lisbon ? The Defence against Globalization??In the modern world globalization have undermined the nation-state and left it without the right measurements to adequately deal with the social and economic unrest that follows in its way. The states, built on contract theories, have an obligation to protect its citizens from the state of nature which seems to have failed as globalization has changed the rules.The purpose of this dissertation is to examine the contract theories of Thomas Hobbes, John Locke, Jean-Jacques Rousseau and John Rawls to identify the elements of a state and create a modern and ideal contract theory. The treaty shall then be used on the Treaty of Lisbon as it can be seen as a contract between the European states to create an entity in the shape of the European Union with the power to defend Europe from the unrest created by globalization.My question for this was as follows:Is the new treaty for the European Union acceptable as a new social contract according to the social contract theories?During my research the following criteria?s for a social contract was found:1.

In this essay the morphing of the interstate relations in the post-World War II Western Europe is taken in to consideration in discussing how these relations were stabilized and consolidated through community cooperation to achieve a state of stable peace. It concludes that the early 1900's of Western Europe comes close to being conditioned by Herz's security dilemma and then continues to analyze the development from this state to one of stable peace. In this analysis pivotal features of the ECSC, EEC and the EC are being scrutinized through the use of Boulding's Stable Peace theory and developments of the very same, in separate case studies, in order to account for the Communities? influence on the peace process.In doing this, conclusions are drawn that external pressures can be very effective in creating an incentive to move beyond an initial state of conflicting self-images and that a stabilizing process has got to provide a long term solution in order to sustain a trustful relationship. In order to provide this long term solution the community cooperations suggests that locking in through institutionalization, harmonization, and the creation of a state of irrevocable interdependence are highly effective..

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

My Finnish grandfather had a passion for architecture, eventhough he wasn?t an architect. In the end of the 1950s he builta wooden summerhouse on a lot outside of a small villagecalled Lempäälä, close to the city of Tampere. Today the lotbelongs to my mother. Every time I visit our summerhouse, itmakes me want to do as my grandfather did ? to build a smallhouse next to it.My project is a proposal for a wooden house on mymothers lot.

This essay concerns the notion of how immigration politics, defined as a political discursive structure that explains and justifies how and why the movement of people into a state's territory is restricted and controlled, has come to present its purpose not as solidarity with the 'immigrants' wanting to enter the state but as a protective measure for the state's citizens. By using discourse theory combined with theories from the International Relations field I attempt to explain why and how such a discourse positions 'immigrants' as a threat to the state.First, I concentrate on why an immigration politics discourse would position 'immigrants' as a threat. I argue that in order for people to construct their identity, the 'outside' what they "are not" has to be repressed. In the same way, the state has to dislocate the "outside" and create threats to uphold its supremacy. These boundaries are set to create a feeling of predictability and security, and ultimately they are a way of making peoples' "world" coherent.
