Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

How do we match our education with the needs of the construction line of business and the requirementsof the Swedish National Agency for education? Is there something that we have to change?In this study I have asked our former students about their opinion of our education and I have also asked them to give me their view on what a good teacher is like. I have been able to benefit a lot from their answers in my efforts to be that good teacher. This survey took place at Facebook.The answers showed that we carry on a piece of solid workmanship. But you can always improve, try harder.

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

De projektsom studerats är Bygga om Dialogen i Malmö, Älvstaden i Göteborg,Vivalla i Örebro och föreningen Byggemenskap.Genom att intervjua en person från varje område studeras likheteroch skillnader i hur man arbetat med den sociala hållbarheten vidbyggnation. I Malmö och Örebro studeras arbetet med att öka densociala hållbarheten vid renoveringsobjekt, hur får de hela områdensom länge haft ett dåligt rykte att bli socialt hållbara där stort fokusligger på att anställa långtidsarbetslösa.I Göteborg och i föreningen Byggemenskap fokuserar man på attföra in den sociala hållbarheten vid nybyggnation och hur vi kan byggahyresrätter som har en lägre hyra än nybyggda lägenheter i dagslägethar..

Background: Today there are high claims on organizations to show a positive economic view. To satisfy the demands and expectations from interested parties it is very important to carefully plan the companies tied up capital and cash flows. Purpose: The purpose with the thesis is to describe what actions organizations take to resolve the conflict between showing a positive cash flow and the need to tie up capital.The purpose is also to explain the different factors that must be considered when making decisions regarding cash flow and capital tied up. Method: A qualitative study of the actions and factors wich must be considered when decisions in swedish construction companies are made regarding cash flow and capital tied up. Results: A model of the factors and actions that affect cash flow and capital tied up in projects.

Kostnaderna för fuktskador i Sverige uppskattas årligen uppgå till mångmiljard belopp.Fuktskador i byggnader medför också en ökad risk för ohälsa hos brukarna. Kunskapen föratt producera fuktsäkra byggnader finns men utnyttjas inte i den omfattning den borde.Den 1 juli 2007 träder en ny upplaga av Boverkets byggregler i kraft. Förtydliganden hargjorts i avsnittet gällande fukt, vilka underlättar verifieringen av entreprenadensfuktsäkerhet. Reglerna innefattar också krav på kritiska fukttillstånd i material. Denna studiesyftar till att kartlägga brister i produktionsskedet och hur produktionen kan utvecklas för attmotsvara de i Boverkets byggregler ställda krav på fuktsäkerhet.Intervjuer har förts med olika representanter i byggbranschen för att ge en helhetssyn avfuktproblematiken.

The purpose of this essay is to investigate the subject field of male vegans and masculinities through empirical method interviews and narrative analysis. The starting-point for this essay is animal ethics, feminist ethic vegetarianism and theories that suggest that eating meat is one part of the social construction of masculinities. The problem formulation is such as follows:How do male vegans construct masculinity? In an attempt to answer such a question there are three problem formulations:What do male vegans think about the connection between manhood and eating meat?How do male vegans relate to the norms in society?What do male vegans think of stereotype conceptions about vegans?I will come to the conclusion that male vegans think that eating meat, as well as drinking beer, is one part of the social construction of masculinities. Male vegans are aware of norms in the surroundings and the strong attachment of meat normativity in the western culture.

This report's aim is that by field measurements determine the function of Aprobo soundproofing material dB2 for reducing impact sounds, the measurements is done in ?the school for fine art? in Umeå also known as ?konstnärligt campus building nine?. The construction technique is used in areas sensitive to impact sound between different floors in the building. The measurement?s is also to do a function control of the buildings sound quality compared to Swedish and European standard when it comes to air sound, impact sound and reverberation time .

Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.

Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..

This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.

The purpose of this study was to highlight how women who have been victims of rape are described in discussion forums on the Internet and how the view obtained is affected by victim and gender constructions. By observing several discussion threads on Swedish internet forums, we have been able to explore how discussions and attitudes are made about women who are victims of rape and which characteristics are assigned females. This study analyzes these attitudes from a gender construction theory and a victim construction theory. Through this analysis, we wanted to gain a deeper understanding of attitudes about female rape victims and if the attitudes are rooted in victim and gender constructions. This study shows that women are often assigned responsibility to a rape if she put herself at risk and if she is assigned negative attributes such as promiscuous, as a liar or if she drinks too much alcohol.
