Passivhus : En jämförelse mellan olika byggnadstekniska lösningar för ytterväggar
This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.
VIBRATIONSSKADOR - FÖREKOMST OCH FÖREBYGGANDE : Analys av ett strukturerat arbetssätt inom bostadsproduktion
Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.
Fjortisgrubbel och tonårskärlek : ? en genusstudie av två svenska ungdomsfilmer gjorda med 35 års mellanrum
AbstractHeadline: Young trouble and teenage love (Fjortisgrubbel och tonårskärlek)Number of pages: 37Author: Annika IlmoniTutor: Amelie HössjerCourse: Media and communication CPeriod: Autumn 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: The purpose of the work was to produce a comparing study of two Swedish teenage films from different periods of time, 1970 and 2005. An analysis was to be made of how love between teenagers as well as the heterosexual relationship in general was depicted in each of the films and further investigate the gender construction in both films.Material/method: With the intention of narrowing down the complexity and make the evaluation more lucid 5 scenes from each film were used for comparison, these were chosen through the Anglo Saxon dramaturgy. To make the scenes more comparable 4 factors were used for analysis in each scene, these were: clothes, recreational activities, behaviour and environment. Beside the above given factors the heterosexual relationship were analysed and compared in each of the scenes through the theory of dominance in dialogue.Main results: The gender construction occurs obliviously in the older film from 1970 while taking place in a more conscious way in the film from 2005. Further on the heterosexual relationship is perpetually depicted in the 70?s film with a submissive girl and predominant boy, the same dominance is easily seen in the more recent film but with a higher rate of equality as the girl is portrayed as the dominant character in almost half of all scenes.

Passivhus av helväggselement i träull
Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.
Ekonomi i Passivhus : En studie av två verkliga byggnader
The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

Energikloka hus i Järinge - energiteknisk uppföljning
Energy-wise houses in Järinge - technical follow-up The company JM built energy-efficient houses in Tensta in Stockholm. They have built a total of 16 houses divided into two parts of A-houses and B-houses. The buildings are an attempt by JM to minimize energy-use of the buildings without affecting the comfort and living standards. The project aims to examine the data for the 16 houses on the basis of data and produce a report showing how the buildings worked through a technical perspective. JM approximates that the purchased energy will not be higher than 95 kWh/m2 per year.
Urban Building i kvarteret Domherren : GA: Galleri A / Gamla Arkitekturskolan
Förslag på hur Arkitekturskolan kan ritas och programmeras om för att bli en offentlig byggnad i staden som ger mycket tillbaka till Stockholms invånare. Form och program är utformat att ge alla som befinner sig i och utanför byggnaden en ny syn på staden där inte bara gatuplan är offentligt och takplan är privat. Runt byggnaden slingras sig en offentlig promenad som leder upp till det öppna takplanet med bra utsikt över staden. Byggnaden har delats upp för att skapa torg på plan 2. GA är en offentlig plats likt en galleria 2.0..
Framtidens energieffektiva flerbostadshus
The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.
FEM i praktiken : En studie i FEM-Designs användningsområden inom konstruktionsprojektering
This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.
Utvärdering av miljöarbetet vid nybyggnad av butik : miljöledning och avfallshantering
According to recent statistics the construction industry is responsible for the largest waste discharges of both dangerous and non-dangerous waste, when disregarding the "non-dangerous" amount of granite waste produced by the mining industry and the waste produced by the pulp and paper industry. Preventive work within waste management is an ongoing practice so to be able to reduce negative environmental effects. One of the most common actions for the companies to take is to separate the different kinds of waste from one another at the construction site. Although by working with the problem in earlier stages of the process a large amount of the waste could already have been reduced.Companies in the construction business that are actively working to decrease environmental impact in their operations often use an EMS (Environmental Management System). By using environmental management as method the company can manage their environmental work so that actions can be taken where they are needed the most.
Riskhantering i vägprojekt : Effekt, nytta och förbättringar
The aim with this thesis is to study the risk management in construction projects at the Swedish Road Administration, SRA. Furthermore, the aim is to find the effects of the risk management. The theorem of this thesis is that the positive effects of the risk management in construction projects create additional value to the project. These additional values are that the project itself becomes resilient and that the project goals are achieved without any significant disturbances.This thesis shows that the risk management in construction projects do not follow the guidelines set out by the SRA. This is due to a lack of education in the method and a difficult method all together.
BIM i förvaltningsskedet
Syftet med den här studien är att förbättra informationsflödet från projektering och produktion in i förvaltningen. Detta för att väcka ett intresse hos förvaltare och för att visa att det finns pengar att spara genom att ta hand om informationen från projekteringen och produktionen.Tidigare studier inom området BIM visar att stor fokus läggs på projektering och produktion men det är ett väldigt litet fokus på förvaltningen när man talar om BIM.Målet är att konkret kunna visa vad informationen är värd och att visa vilken information förvaltare använder och var den finns i byggprocessens skeden före förvaltningen.Rapporten bygger på en litteraturstudie, intervjuer och beräkningar. Förvaltare har blivit tillfrågade vilken information de använder i förvaltningen och sedan har projektör och entreprenör blivit tillfrågad ifall denna information finns att tillgå i projekteringen och produktionen. Värderingen av informationen har sedan gått till på två sätt. Det ena sättet är att bedöma kostnaden av att uppdatera information mot kostnaden att ta fram information på nytt.
"Måste det vara så krångligt?" : Att arbeta med teknik i förskolan
The purpose of this study is to explore how preschool teachers succeed in their mission to conduct work that will enhance children's interest and knowledge in technology. The study was conducted by qualitative semi-structured interviews among eight teachers at seven preschools in the same municipality. The method was chosen because I wanted to get as detailed and full answers as possible. I also wanted to find out their individual perceptions. The result shows that most of the teachers think that they have insufficient knowledge to practically work with technology. At the same time they?re expressing that technology is a broad area that sometimes is a little more complicated than it needs to be.
