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.

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced. The overall market they are concentrated on is to different institution such as schools, hospitals etc.The purpose of this work is to investigate possibilities to improvement of material- and production control at JELD-WEN. The report will handle the master production schedule to and from the production divisions within manufacturing industry. Focus will be on the way for information- and material flows from arrival, transport within the company and further on to customers.Further a map of the flow was performed which gave a clearer picture of the connection between the flow of information- and material for the manufacturing process. On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses.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.

I avloppsvattnet förekommer både naturliga och antropogena ämnen som kan orsaka en negativ miljöpåverkan, såsom eutrofiering och en syrefattig recipient. Förekomsten av näringsämnen och organiskt material kan också vara en värdefull resurs, för det slam som återstår efter reningsstegen i avloppsreningsverket kan användas för att höja näringshalten i till exempel skogar och på åkermark. För att minska risken för skador på reningsprocessen, en negativ miljöpåverkan på recipienten genom skadliga ämnen som passerar genom avloppsreningsverket samt en negativ miljöpåverkan på grund av ett förorenat slam är det betydelsefullt att fokusera på mängden skadliga ämnen som förs till anläggningen. Syftet med examensarbetet är att kartlägga förekomsten av hushållskemikalier hos sex hushåll i Västerås som är anslutna till det kommunala reningsverket, studera befintlig litteratur som beskriver vad som sker med utvalda kemikalier då de når avloppsreningsverk i allmänhet, och sedan jämföra detta med Kungsängsverket. De sex hushållens sammanlagda antal produkter var 293 stycken, varav 66 var rengöringsprodukter, 16 tvättprodukter, 112 badrumsprodukter och 99 stycken var garageprodukter.

Under 2010 antogs en ny regionplan för stockholms län, RUFS 2010. Planens mål är att ?Stockholm ska bli Europas mest attraktiva storstadsregion?. Dialog och samverkan har varit viktiga utgångspunkter både för planprocessen och det framtida arbetet med att genomföra planen. Regionen har arbetat med att involvera kommunerna i regionplaneprocessen, bland annat som ett sätt att förankra regionplaneringens innehåll även i kommunernas egna strategiska planering.I den här studien har jag undersökt relationerna mellan medborgarna, kommunerna och regionen i planeringen, för att söka svar på frågor om makten över den strategiska planeringen, vem som har tillträde till arenorna där beslut fattas samt medborgarnas möjligheter till inflytande i den regionala planeringen.För att svara på mina frågeställningar har jag gjort en fallstudie i stockholmsregionen, där jag studerat den nya regionplanen och ett antal stockholmskommuners översiktsplaner.

Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in modern buildings. In modern contemporary construction, large glass panels are often the ideal because of increased light inflow and for architectural purposes. However, this can generate several negative effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that window shutters could have accommodated historically. This thesis identifies a lack of knowledge about interior window shutters in the Swedish building stock.

The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).

Cykeln har på senare år fått en allt större roll inom transportpolitiska sammanhang. Det finns ett intresse att öka användningen av cykel, framförallt av miljö- och hälsoskäl. Därmed finns det också ett intresse för att kartlägga cykelvägar på samma sätt bilvägar är kartlagda. Om Sveriges cykelvägar fanns samlade i en databas skulle utveckling och underhåll förenklas. Det skulle även vara möjligt att ta fram informationstjänster som t.ex.

Servervirtualisering har blivit en allt vanligare syn inom IT-världen och särskilt för de som har stora serverparker eller för verksamheter som är ute efter att effektivisera och skära ner på sina kostnader. Eftersom att virtualisering tillåter konsolidering av hårdvara leder detta till en lägre energiförbrukning och behovet av stora lokaler minskar. Med servervirtualisering går det att köra samma arbetsbelastning på mindre antal servrar än det behövdes innan bytet till servervirtualisering.Då det kan vara svårt att hålla reda på vad ett virtualiseringssystem har för egenskaper och funktioner har vi i denna studie valt att göra en jämförelse mellan tre marknadsledande hypervisors från: VMware, Microsoft och Citrix. Innan jämförelsen redovisas i studiens tabeller presenteras en övergripande teoridel kring servervirtualisering och sedan en genomgång av de kategorier som ligger i fokus för jämförelsen.Studien kommer också att visa på hur en P2V-migrering går till med två av studiens virtualiseringssystem. En fysisk server med Windows Server 2012 som har webbserverollen installerad migrerades utan problem till en virtuell maskin på respektive virtualiseringssystem.

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity. In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.

The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.

Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.

The aim of this Masters thesis is to examine and analyse how the public librarys mission is interpreted and formulated in a selection of library related journals. The journals are both international scientific referee journals from the LIS field and journals with a closer connection to the practitioners within the public library field. The idea is that these journals can be seen as windows to an academic theoretic perspective on public libraries, as well as to the practitioners way of talking about the librarys mission. The study also aims to examine if there is a difference in the way that the librarys mission is interpreted and discussed among theorists and among practitioners within the field. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory, and the method is text analytic.

In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.
