Fuktproblematik i platta på mark : En analys av uppkomsten till fuktproblem

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

Planering, förutsättningar ocheffekter av implementering avsolceller i stadsutvecklingsprojekt.

Today, buildings utilize 40 % of the total energy consumption. New energyrestrictions and directives have entered the construction industry. Photovoltaic is asustainable, clean and quiet solution that integrates well in the urban environment buthave not yet reached a breakthrough on the Swedish market. The conditions for solarenergy production are often set in the early planning stages where they rarely arebeing prioritized.This master of engineering project focuses on identifying problems regardingimplementation of photovoltaic in city development projects and giving suggestions topossible improvements in the planning- and construction process. It also givesrecommendations on how the conditions for energy production can be optimized inthe early zoning stage.By conducting simulations with PVsystV5.21, on three ongoing city developmentprojects in Umeå, Malmö and Stockholm and by carry out and analyzing interviewswith city planners, constructors and architects, some conclusions have been made.Several improvements, both politically, with changes in the subsidization systemand/or instatement of a new law with feed-in tariffs, and within the solar- andconstruction industry itself, with better communication between different parts of theprocess as well as better use of experience, can be made.

Robot-Assisterad Gradningscell med Force Control

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

In this work a new design for S:t Erik?s square in Uppsala is being proposed. The square is situated in the middle of the city, surrounded by historical buildings. Today the square is a parking lot. The aim of the design proposal is to promote life and activity of pedestrians and cyclists.

Emballage för väggelement i trä : Paketering, hantering, lager och transport

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

Hantering och mellanlagring av jordmassor

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

Värdefull eller värdelös? - Kulturhistorisk värdering och färjestationen i Helsingborg

This essay in historical archaeology deals with cultural-historical values of buildings and inthis case the old train- and ferrystation in Helsingborg. The building has from the day of itsopening in 1898 been exposed to threats of demolition since its original purpose was as atemporary building with intension of being replaced within a couple of years. After havingseen two World Wars, eventhough Sweden never participated, and the ferrytraffic with its upsand downs the station was an important part of Helsingborg. All the ferrytraffic over the straitto Denmark was handeled by the old train- and ferrystation untill 1955, when a competativeferrycompany was built close to the old station. After a hundred years of service the oldstation was closed down when a new station was built i Helsingborg in 1991 with theintension of gathering all travelers in one building.

Beslut om investering i alternativ energi : en studie om hur lantbrukare fattar beslut vid investering i halmpanna

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Jönsaplan blir Östra torget : ett torg för sin tid

This project is about Jönsaplan in Landskrona. Jönsaplan is situated at the center of Landskrona in a part called Södra centrum which the municipality is developing, mainly by building new residential buildings. Today, Jönsaplan is not a functioning square. This is due to a ferry terminal and its many fences that block the way for people. In this project, I have assumed that the ferry terminal will be moved somewhere else so that Jönsaplan can be a real square. By studying The Concise Townscape by Gordon Cullen and Byens uttrykksformer by Thomas Thiis - Evensen and three reference places, Daniaparken, Raoul Wallenbergs torg and Norr Mälarstrand, I came up with a number of guidelines for my design proposal for Jönsaplan.

Effektivisering : En utredning om åtgärder på en industrifastighet

AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.

Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.
