This study includes a life cycle assessment, LCA, on an ecological produced cotton shirt for the company Reflective Circle, which designs ethical and ecological clothes.Initially were cotton farming and textile production studied to gather basic knowledge about the processes. Since this shirt is being ecological produced in the whole production chain, we studied what an ecological production means, but also how a conventional production works. When this was done we could start to discuss the differences and similarities between the production of the shirt and general conventional production.When the LCA was first initiated, the main focus was on the green house gas emissions from the manure at the cultivation. Thereafter the process steps such as picking, ginning, carding, spinning, weaving and sewing were being studied. The picking is done by hand, but the rest of the processes are handed by machines which consumes energy.

Over the next few years, major investments in healthcare buildings is to be performed. Most surgical theaters are in need of technological upgrades as the technology is outdated. In most cases not only a refurbishment is performed but also an expansion. The basis for expansion, is due to a large increased number of patients, but also to the complexity of the refitment. Partly it's because evacuations are difficult to implement and the disturbance that occurs in conjunction with the refitment.Löwenströmska hospital undergoing a technical upgrad.

Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.

This paper is written as an examination paper at the University of Jönköping. The subject is chosen by Peab Sweden in Jönköping with whom further cooperation has been hold. The aim is to compare building methods and building materials in Sweden, Finland and Germany for further inspiration for Peab?s own market.BackgroundThe development of the construction industry develops new materials and methods to the market which has been forced by shorter construction times and the environment aspect. To pursue the development, further knowledge exchange should exist between the countries.

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

This report presents thesis of Liisa Kokkonen in collaboration with Muovikilpi Oy.The project?s goal is to find a new construction for an existing lamp made of acrylic. Form and design retains and the manufacturing occurs at Muovikilpi Oy. The project contains the new construction and manufacturing of the lamp and also a proposition for a set with floor and wall lamp.  The paper gives an outline of acrylic as material and how it reacts with light.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

This essay examine the meaning produced around bodies and body fat in the queer community, but also in the surrounding straight community. The author has interviewed fat activists, and are using queertehory, to examine and analyze the relationship between body fat and the understanding and construction of sexuality and gender. The author concludes that even if norms around body shape and body fat are overlapping between the two contexts to some degree, they also differ. In the straight community, people with larger body shapes and sizes are punished, and encouraged to stay, or become, slim. However, in the queer community, ?fat? or bigger body sizes are not frowned upon in the same degree.

Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

People who live in northern part of the world spend much more time indoors than those who live in warmer countries. In addition that home should be safe, it should also protect one against heat, cold, sunlight and pollution. The indoor environment is affected by installations, material and how the building is formed. Those anomalies that are visible, felt or smelled can be noticed and be rectified. But it?s much more difficult if these abilities are missing.
