Den offentliga upphandlingens påverkan på entreprenörer : En studie av små och medelstora byggentreprenörer
Public procurement in Sweden is regulated by the Act on Public Procurement (lagen om offentlig upphandling, LOU, in Swedish). The Public procurement in Sweden stands every year approximately for 500 billion Swedish crowns of the taxpayers? money. It is therefore important that the money is spent in the best possible way. The focus in this study is set on the relationship between the small- and medium sized building entrepreneurs and the government.
Energibalansberäkning
Abstrakt - As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .
Kunskapshus eller offentligt vardagsrum? En undersökning av Lunds stadsbiblioteks ombyggnad
In this study my aim has been to discover what connections can be made between the way of creating a library building and the general values concerning the library activities and the library users. What kind of ideology could possibly be reflected in a library room? My study includes two different parts. First of all there is a theoretical section based upon literature relevant for the subject. Here I try to focus on the libraryÕs role in society as a public room.

Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök
In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.
Tätskikt i klimatskal : En studie av byggentreprenörers arbetssätt
As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.
Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?
This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.
Flyttprocessens påverkan på identiteten ? utveckling eller avveckling? : En fallstudie kring flytten av Hjalmar Lundbohmsgården i Kiruna
The purpose of the thesis is to investigate and analyze how three different actors linked to the urban transformation in the city of Kiruna, in this case LKAB, the Municipality of Kiruna and the County Administrative Board of Norrbotten, believe that the identity of a historical monument that is marked cultural heritage is affected by future relocation. The second part of the study is to investigate the impact the building might have on the city in the future. This study is based on the relocation of Hjalmar Lundbohmsgården.The study is based on a qualitative approach in which five informants from the three actors were interviewed. The interviews have been analyzed through thematic analysis, where a combination of theoretical thematic analysis and empirical thematic analysis was used. The result shows that the new location of Hjalmar Lundbohmsgården is preferred to be in a suitable context close to other cultural buildings. All informants agree that accessibility is a fundamental element in, which a synergistic effect is an increase in visitor numbers.
Överklagande och dess roll inom bostadsbyggandet : En granskning av plan- och bygglovsprocessen
The aim of this diploma work was to obtain a review of the appeal process in Sweden under the Planning and Building Act and the possibilities of appeal in the planning and building permit process. The work was intended to identify potential problems surrounding the appeal process and possible efficiency measures. The goal was to form a report that provides a satisfactory overview of the appeal process in theory and practical application as well as provide relevant concrete proposals on how the appeal process can be streamlined.Background and facts surrounding the work were taken from different types of literature and through several interviews with representatives in government, industry and politicians.The main problems related to the appeal process are in the long processing times and the high number of appeals. There is a great interest to streamline the appeals process and the government is going to launch studies in which possible future actions will be investigated.It is possible to appeal for up to two instances before you need a so called ?leave to appeal? in order for your complaint to be passed on to the next instance.
Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

En mötesplats med utsikt och ett öppet rum för insikt : En studie av folkbiblioteksarkitektur och synen på folkbiblioteksrummet - Exemplen Lomma bibliotek och Halmstads stadsbibliotek
The focus of this two year master?s thesis in Library- and Information science is the study of two Swedish Public Library buildings with the examples Lomma and Halmstad. The main goal and purpose of the thesis is to try to uncover which views and values of the public library are expressed in the examined libraries; and to what extent these views manifests are shown in its architecture.The theoretical framework is based on Raymond Williams?s cultural concepts of effective, dominant culture and the two extremities of this culture, called residual and emergent cultures. A second aspect is Yi-Fu Tuans concepts of Space and Place.
Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system
BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Chewing behaviour of growing cattle
Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.
