This major project in Building Engineering has its focus on inquiring into what methods has been used in the planning process of the residential buildingLjusbojen 1. This project has been conducted in cooperation with Kadesjös Ingenjörsbyrå AB, an engineering contractor firm which also acts as the property developer. Initially several different general methods for planning residential buildings have been presented. After the methods from the process of building Ljusbojen 1 has been analyzed compared to the general methods presented in part 1. This shows what the determining factors are during the planning process; factors such as cost, quality, time management, know-how and environmental issues.

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.

For the Swedish artist Björn Lövin, the personal was a problem. In his first exhibition in Moderna Museet, Lövin observed through the fictitious character Mr. P (for »Personality«) the ruptures in the Swedish welfare state. The exhibition Konsument i oändligheten och Herr P:s penningar (Consumer in Infinity and Mr. P?s Money) (1971) was composed of two environments, through which a veridical working class apartment and a high street with life-sized mannequins and furniture characteristic of its time, visualized the societal discrepancies in the welfare state as well as the art world of the early 1970s.

Vargaslätten is a 15 hectare large privet garden in Halland in the south-west of Sweden.In the beginning of the 1990s Gunnar O.Westerberg, the owner of Vargaslätten,commissioned a work from the young landscapearchitect, Rolf Efvergren, to writeVargaslätten ? tillägnad naturen. It was a discribing work of the current status of the gardenand the summer-house of Vargaslätten. Vargaslätten ? tillägnad naturen was acomprehensive work with a detalied inventory of all the plants, the buildings, the descriptionof the surroundings and the history.

The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

The homes that were built in the 60?s - and 70's are now so dilapidated and worn that they need thorough renovations. These renovations are expensive to implement for the landlords, which means that the funding for these renovations can create problems. Currently there are no government subsidies for these renovations. This report will examine how Förbo performed the renovation of Säteriet.

This thesis examines the sheep shed called Ronningsgift, and its historical functions and geographical location. The study aims to make a comprehensive gathering of the existing knowledge and to shed light on new theories about the history of Ronningsgift. This is done through desk research including literature and archive search, as well as an investigation and description of the construction and materials, and an interview. Further, I got the opportunity to take part of the results of two C14 samples from Ronningsgift. The literature and archive search shows that the most common theory of the historical function is as a guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

Mellan åren 1965-1974 genomfördes ett unikt bostadsbyggnadsprojekt i Sveriges historia. För att lösa den dåvarande bostadsbristen beslöt Riksdagen att det under en tioårsperiod skulle byggas en miljon bostäder. Detta projekt kallas således för miljonprogrammet. Under årens gång har många kritiker gjort sig hörda då de kritiserat fenomenet på flera nivåer. Ord som segregation, visuell monotoni och storskalighet har använts i beskrivandet av miljonprogramsområdena.

This thesis has been carried out at the Building and Civil Engineering Programme at Chalmers University of Technology in cooperation with NCC Technology. The study aims to investigate the optimal design of a library of standardized structural solutions for in-house multi-family buildings and what benefits it brings. Today NCC use technology platforms to improve efficiency and simplify the construction process. The platforms provide the constructors guidelines on how construction details should look like, but the details are not complete. NCC Technology started in the spring of 2013 a project to investigate what benefits there are to create a library of standardized structural solutions for the constructors, with more detailed solutions than in the platforms.

When the Eolshällproject was completed for the first time, a great deal of moisturedamage was discovered. Therefore the structure completion was removed andreinstalled. The project was originally planned to cost a total of 126 million SEK, but thefinal costs landed on 271 million SEK. What caused this failure? Were the designs poor,was the technology used too advanced, or was the project not managed properly?Based on the Eolshällproject, theses will be presented about what may have caused themoisture damage.
