Investeringskalkyl baserad på ett flerbostadshus energiprestanda

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Hållbar utveckling : Begreppets utveckling och användning på kommunal nivå

This thesis concerns how local governments use the concept sustainable development, and what the concept means. The concept of Agenda 21 and local Agenda 21 will also be discussed in this essay, because it's an instrument for local governments to specify their work towards sustainable development. I have interviewed civil servants in leading positions in the municipalities? work with environmental questions and sustainable development. In the choice of method for this thesis, I use the qualitative method and for the interviews I chose the ?semi structure way of interviewing?.This thesis shows that local governments? implementation of sustainable development and Agenda 21 differ between the municipalities.

Kompensering av reaktiv effekt vid vindkraftverk

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Inköpsoptimering och kostnadsreducering

This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

Flödesapplikation - företagsbaserad utbildningsmodell på Internet

Intern företagsutbildning via e-learning är ett aktuellt ämne, framförallt eftersom företagen ser det som en chans att bli effektivare och spara pengar. Av de fretagsanpassade utbildningsapplikationer som finns på marknaden idag, är nästan samtliga skapta för att förklara fr användarna (kursdeltagarna) hur saker och ting ska fungera. Deras stora svaghet ligger dock i att förklara och förmedla varför dessa saker fungerar, varpå man riskerar att misslyckas med att förmedla en djupare förståelse och skapa en bättre kunskapsbas. Därför finns det troligen många anställda på företag som har fått lära sig hur allt runt om kring dem fungerar, men inte varför det nu fungerar som det gör. Denna examensrapport redogör för vårt arbete med att ta fram en webbaserad applikationsmodell, utvecklad i Adobe Flash, tilltänkt för utbildning, och som på ett enkelt men effektivt sätt synliggör hur olika typer av företagsflöden fungerar och, framförallt, varför de fungerar på detta sätt.

Riktlinjer för mobil applikationsutveckling

Marknaden för mobila system har utvecklats enormt snabbt de senaste åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas.

Tesauruskonstruktion i ämnet landskapsplanering

This research paper is a thesaurus construction for the interdisciplinary subject of landscape planning. The personnel doing the indexing of documents at the Swedish University of Agricultural Sciences had earlier expressed a need for such a work within the fields of Landscape Architecture and Landscape Engineering. However our objective was not to create a complete thesaurus, but instead a basic construction which the personnel at the Agricultural University could expand upon. The actual construction is based upon ISO 2788-1986, Documentation Ð Guidelines for the establishment and development of monolingual thesauri, and Aitchison, Gilchrist and BawdenÕs Thesaurus Construction (1997). The line of enquiry taken has dealt with the problems relating to the collection, selection and control of indexing terms.

Enkla kemiska processer inom förskolan : En kvalitativ intervjustudie om förskollärares uppfattningar och tankar om läroplansmålet enkla kemiska processer

The aim of this study was to investigate preschool teacher?s perceptions about the curriculum goal concerning simple chemical processes. The result was based on narratives received by a qualitative study and semi-structured interviews of six preschool teachers. The results of the study showed that preschool teachers perceive that they actually are working in a relatively small scale with simple chemical processes and they do not really know what simple chemical processes are, and do not feel very familiar with the subject. Water, dough, mud, paint and baking were the most common activities that were used when working towards the curricular goal. However, it was never explained to the children that it was simple chemical processes they were working with during the activities, neither was it discussed among colleagues because of the uncertainty about the concept.

Studie till uppstartande av annonskatalog

Sten Jonsson wants to start a production of an advertising catalogue for small companies in Sweden. Acatalogue where the advertisingcost is so low that most of the companies can afford to participate. Thecompanies who will advertise should be manufacturing companies in trades of carpentry, sheet metalworkshops, forging workshops and engineering workshops.The catalogue will facilitate for the manufacturer to reach the costumer without any middleman.Without a middleman creates a possibility for an opinion about the product at the same time as theprice can be held low. A catalogue of this type would benefit the marketing of the companies at the sametime as it would generate an occasion for innovations.The possible target groups are property companies, construct companies and farmers.A market research has been carried out contained a postal interview and a phone interview. Themarket research carried out to get an understanding in what the companies think about the idea butalso to see if the companies are in interest of advertise in the catalogue.

Otrogen läsning : Debatter om feminina publiker 1808-1815

Gendered reading has a history of intense debate and negotiation. In this essay I will examine how feminine and masculine reading was construed in the early 19th century through three Swedish texts that all give a didactic, moral and instructive opinion about gendered reading. They consist of an advice manual, a collection of letters and a periodical featuring an assortment of suitable reading material, all published between the years of 1808-1815 and directed to a female audience. As the male sex was generally considered the invisible, desirable norm and the female sex tended to be viewed as deviant and problematic, gendered discussions are inclined to focus on the latter. I will argue that female reading is largely construed in relation to the bourgeois marriage while the male is construed in terms of citizenship.

Riskanalys på Karlshamnsverket - Påverkan vid en framtida höjning av havsnivån

Människan har genom sin industriella framfart bidragit till ökade nivåer av växthusgaser i atmosfären och på så sätt rubbat den balans av gaser som naturligt förekommer. En klimatutveckling med trender som tyder på en framtid med varmare klimat är en av konsekvenserna av den process vi i alldagligt tal benämner växthuseffekten.Ett varmare klimat förväntas medföra förändringar av en rad faktorer, där medelvattenståndet i världshaven är en. Med en geografisk lokalisering i direkt anknytning till kusten och en topografisk lokalisering på dryga 2.65 m över havet skulle Karlshamnsverket kunna vara i farozonen för de konsekvenser en höjning av intilliggande hav kan medföra. Karlshamnsverket är ett värmekraftverk som ägs och drivs av Karlshamn Kraft AB. Anläggningen ligger utanför Karlshamn, vid Blekinges kust, och redan idag råder viss problematik vid högvattenstånd.

Anhörig eller anställd personal? - Vilken vård efterfrågar äldre när de drabbas av sjukdom

There are a lot that shows that there will be an increasing demand on the achievements of the relatives. How can this development be answered to? Shall the achievements be concentrated on giving support to the relatives, or will there be a concentration on nursing staff? The purpose of the study was to enlighten who elderly people will be nursed by if a disease affects them.

Vandenbergh 9: Kontorskomplex till moderna bostäder

Stockholm är en växande stad och för att bemöta det behov av bostäder som expansionen medför, krävs att befintliga fastigheter utvecklas och får nya, bättre anpassade ändamål. Det är framförallt viktigt att utveckla de fastigheter som är belägna i attraktiva områden med pågående stadsutveckling eller goda möjligheter för ny stadsutveckling.Denna rapport behandlar utvecklingen av Vandenbergh 9, ett kontorskomplex från tidigt 1970-tal till ett modernt bostadshus. Rapporten resulterar i förslagshandlingar över hur den invändiga gestaltningen kan komma att se ut. Förslaget följer alla de lagar, stadgar och rekommendationer som idag ställs för byggnation i Sverige.Detta resulterade i sex individuella plan, men för att främja hållbart och rationellt byggande har ett stort fokus lagts på modulbyggande. Rapporten redogör för hur en fastighet i en stor skala kan utvecklas och erhålla ett nytt syfte..
