Effektivisering av LCA med hjälp av BIM

This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will make the LCA more comprehensive, unlike e.g. aluminum cans. Recently there has been a development of a working procedure in the construction industry.

Visionen BIM

IT-användandet i byggbranschen har banat väg för nya, effektivare arbetssätt och det finns visioner om hur det ska fungera. Syftet med vårt examensarbete är att ta reda på byggbranschens användande av, och vision om BIM. Vad är BIM ? Building Information Model?Kort beskrivet är BIM en modell där all information för ett byggprojekts hela livscykel kan hanteras. BIM förenklar det fortlöpande arbetet genom hela byggprocessen genom att tillhandahålla information om projektet som är relevant, uppdaterad, integrerad, fullt koordinerad och av hög kvalité.

iPad på en byggarbetsplats : Det effektiva och papperslösa sättet att arbeta på

Quality assurance of construction projects and create effective ways of working, is intoday's pressed position, major objectives for building contractor companies. This thesis is an attempt to see if it is possible to achieve these goals with the new modern tool iPad.The author of this thesis has during the latter half of his one year practice work in Uppsala for the Swedish building construction company NCC Construction Sverige AB, conducted a study on the possibility of using the iPad on an construction site. This has been done with active field studies in which applications have been tested and also the supervisors receptive. The usability of the iPad has always been in focus since it is important that the applications are easy to use and easy to learn.The results of the work, as presented in this report, points at opportunities in efficiency if the iPad is introduced and used on construction site. There are many useful applications for the iPad, and with a system that can handle the synchronization between the iPad and the computer, the workflow will be streamlined significantly..

Ombyggnation av ett stall för bundna mjölkkor till boxsystem för rekryteringskvigor

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..

Social-engineering ett hot mot informationssäkerheten?

Den här rapporten tar upp ett annorlunda hot mot informationssäkerheten, som inte hårdvaraeller mjukvara kan stoppa. Detta hot kallas för social-engineering, och det som gör detta hotfarligt är att de anställda och chefer i en organisation, kan hjälpa utövaren av socialengineeringutan att de själva vet om det.Det går inte att förhindra att dessa attacker sker, men man kan förhindra de negativakonsekvenserna av en sådan attack. Denna rapport tar upp hur man ska göra för att enorganisation ska kunna fortsätta med sin verksamhet, efter en attack av social-engineering. Ivärsta fall kan en attack av social-engineering innebära att ett företag aldrig återhämtar sig.Detta kan bero på att organisationen har förlorat alla sina kunder, förlorat marknads andelar,eller för att de ansvariga och viktiga personerna i organisationen har blivit dömda föroaktsamhet och sitter i fängelse.Denna rapport ska informera och få er att vara uppmärksamma och medvetna om dessahot, som ni kanske inte vet finns. Ni ska få kunskap och lära er känna igen de olikaförklädnaderna en utövare av social-engineering antar..

Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

Skolan och elevers hälsa : En studie om hur skolan arbetar med elevers fysiska och psykiska hälsa

AbstractThe purpose of my study is to examine the experiences and opportunities to support teachers in preschool to help children in vulnerable environments, a good self-esteem. Hindberg (1999) writes that of all children today are growing up in Sweden, so ten percent live in families where there is abuse. According Pousette (2011) as the National Public Health Institute has a new appreciation for families where there is hazardous and this means that drinking or abused so much that it can become an addiction. They appreciate the investigation that twenty percent of all children in Sweden are growing up in these conditions.The results show that teachers' work is about building a sense of security in the children, both the teacher and the environment. It also shows that teachers believe that it is important to work with the self-esteem of all children, but especially children living in abusive families.

BIM - Förvaltarens Framtid

For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof.

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.

Anställdas förvärv av värdepapper : Beskattningstidpunkten när förvärvet är förenat med förfoganderättsinskränkningar

It has become increasingly simple for companies to offer its employees shares in the form of incentive or option plans to acquire.  Companies motivate incentive plans with employee buy-outs that it will lead to higher involvement of work. The offers are often associated with disposal restrictions to the employee such as not immediately dispose of shares or that the employees will have to remain of employment within a certain timeframe. The problems with disposal restrictions are that it makes it difficult to determine the point of taxation.When shares deemed acquired at the time of share subscription the benefit will be taxable as income from service and the increase in value income from capital. When shares are deemed to be acquired only after cessation of disposal restrictions this will result in that the benefit is taxed only once.After the Supreme Administrative Court rulings in 3167-09 and 3168-09, it is now obvious that the acquisition is deemed to occur at the time of acquisition. The problem is not yet solved because the constant development of the security market needs to be considered.

AUSTERS 1:61 - ett fritidshus på Gotland

A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.

Energieffektivisering och solenergi i en universitetsbyggnad : Undervisningshuset och Biblioteket i Uppsala

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

Trådlösa nätverk

This report describes what wireless local area networks are and the use and configuration of them. These WLAN as they also are called can be used both in new installations and expansion of existing networks. Further on this report reveals security in this area. Security is incredible important in all networks not at least wireless because you don?t have to be in the environment physically to get the information, you only have to be in the coverage area that can be several hundred meters.
