En 200 år gammal skånelänga uppnår 2000-talets energikravDetta arbete redovisar hur konstruktionsförbättringar på en gammalskånelänga kan förbättra husets boendestandard samt att huset tack vareförbättringarna uppfyller dagens krav ur energisynpunkt. Detta utförs utan attinskränka på dess arkitektoniska ursprung. Vi har tagit fram lösningar förhuset som förbättrar grunden väggarna och vinden, kortfattat tilläggsisolerasdessa och förbättras. För att få svar på hur våra förändringar har påverkathuset så har vi gjort beräkningar i ett energiprogram som bevisar att huset harförbättrats energimässigt och uppfyller dagens krav enligt BBR. Beräkningarhar även utförts i ett program som behandlar köldbryggor, detta för att visavad man kan tjäna på om man utför en åtgärd för at förhindra en köldbrygga..

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Water constructions - as a design element in public spaces is the title of this Master thesis, with a focus on waters function and meaning in the urban environment. By way of introduction, mans relationship to places is described and the factors that contribute to the reality that we prefer some places more than others. A good place to stay is open but well defined, gives protection, offers a good view and is varying in topography and vegetation, together with contents of single landscape elements like visible water. This study then continues to discuss mans relationship to water and its means for our wellbeing. Despite the fact that people have a different relations to water due to personality, background and age, it?s an element that raises positive feelings, interest and aesthetic pleasure for most people.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.

Italy is the third largest market in Europe with a population of almost 58 million. The country is the tenth most important market for Swedish sales. Italy has a fairly good economy at the moment and the forecast tells of an increasing strength during coming years. Despite all of this, Sweden is exporting a fairly small amount of wood to Italy. Only around 2,3 % of all Sweden?s wood export goes to Italy.

Syftet med undersökningen var att undersöka hur barn bygger utifrån en inspirationsbild samt om barnen lär sig mer då de utmanas av en pedagog. Undersökningen genomfördes med hjälp av observationer av barn på en förskoleavdelning där samtliga barn var tre år gamla.  Resultatet visade att de flesta barnen byggde vertikalt. Endast ett barn valde att bygga horisontellt och använde inspirationsbilden som underlag till sitt bygge. Resultatet visade även att det har stor betydelse om det finns en pedagog närvarande som utmanar barnen vid bygg och konstruktionslek och kan synliggöra deras lärande. Skillnaden i barnens byggande när de blev utmanande av en pedagog var att de använde sig av flera byggklossar när de byggde samt av flera olika geometriska former på byggklossarna..

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine Building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

The design of buildings is today considered to be crucial for obtaining sustainable development. Research concerning sustainable building is considered to be a Swedish area of strength and development projects as Hammarby Sjöstad and Bo01 are often pointed out as Swedish prime examples of sustainable building. Some still argue though, that that these projects should not be presented as sustainable, due to its incompetence to meet their objectives. This contradiction has attracted my curiosity. By doing this study I hope to gain understanding about the difficulties Bo01 and Hammarby Sjöstad are surrounded with and its significance for sustainable development.

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

This thesis project is a vision of an identity building in Gothenburg, situated on the pier called Bananpiren. The purpose of the project is to create interest and stimulate discussions around the place and the building.In order to gain inspiration of what such a place can contain and express, a number of similar projects have been analysed, for example the Sydney Opera and the Yokohama International Port Terminal.A number of suggestions was then created and analysed, all of which are presented in chronological order in order to show the rejections and the developed designs that resulted in the final formation to proceed with.The result was finalised in a number of presentation images of the project that can be used by Cullbergs Arkitektkontor AB when presenting the project..

This Master of Science thesis was a part of Pharmadule Emtungas project to construct a mobile automated cell for welding of carbon steel pipe (Heating, Ventilation and Sanitation). Pharmadule Emtunga is using a modular building concept for building pharmaceutical factories. The modules contain these pipes. The goal of the thesis was to present concepts for technical solutions regarding welding methods and fixtures for the cell. Conceptual models for the cell were made with aid of CAD software.

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.
