Life Cycle Cost : Studie om LCC som verktyg att utva?rdera geoenergianla?ggningar

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

Energi och klimatanalys O-huset på Campus i Halmstad

AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.

Energisystem med utnyttjande av restprodukter för gödsling av Salixodling för energiproduktion : studier av kretslopprojektet i Enköping och dess applicering på en kommun i Ryssland.

The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.

Vad är viktigast i staden? : Utveckling av ett lokaliseringsverktyg för stadsplanering

This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.

Viabilitet av Neisseria gonorrhoeae, Propionibacterium acnes och Bacteroides fragilis vid förlängd förvaring i transportröret COPAN E-swab?

En säker bakteriediagnostik kräver en korrekt provtagningsteknik, ett lämpligt transportsätt och rätt odlingsteknik. På grund av centralisering av verksamheter och ekonomiska begräsningar, är transport av prover till mikrobiologilaboratorium mycket vanligt. Detta medför behov av ett transportmedium som håller känsliga bakterier vid liv under långa transport- och förvaringstider. Dessutom skall transportrören klara av maskinell utodling som kräver ett vätskebaserat provtagningsmedium. Denna övergång minskar även arbetsbelastning och förbättra ergonomin hos personalen.

"Jens Holgerß af Glimynge" Om en borgbyggares intentioner

Glimmingehus is one of the most well preserved medieval castles in Sweden. This essay examines why it was built ? what were the intentions of the Lord, Jens Holgersen? Even though we?ll never be able to ask him, the answer to the question ?why?? can give us aninsight of how a man of his position thought in the Late Medieval time. To answer the question the castle are explored through three different angles ? the Lord of the castle and thesocial context the castle was built in, the landscape surrounding Glimmingehus ? has Jens Holgersen left any structural clues there, and finally the castle itself ? how has a potential visitor experienced Glimmingehus? The methods are greatly influenced by Gunhild Eriksdotter, who in her book Bakom fasaderna explores the possibilities of an analysis ofexperience together with an analysis of function in the archaeology of buildings.

Träning och manuell behandling för att minska impingementliknande symptom i skuldran hos idrottare? : En systematisk litteraturstudie

AimThe purpose of this study is to investigate whether there is scientific evidence that exercise and/or manual therapy can improve function, in terms of increased mobility and strength on shoulder impingement-like symptoms among athletes. Another aim is to investigate whether these interventions can reduce shoulder pain.MethodA systematic review was conducted in the databases PubMed, CINAHL, PEDro and Amed. A total of thirteen articles were selected for further review and compilation. They were then graded for level of evidence according to the PEDro scale and the Swedish Council on Technology Assessment (SBU).ResultsThe systematic review shows that there is strong scientific evidence that acupuncture and heat can reduce pain in athletes diagnosed with supraspinatus-tendiopathy. There is limited scientific evidence that exercise increases strength, limited scientific evidence that stretching increases mobility and insufficient scientific evidence that a combination of treatments, with both exercise and stretching, reduces pain and increases function in overhead athletes.ConclusionsExercise and manual therapy can reduce pain and/or improve function in terms of increased mobility and strength in athletes with shoulder impingement-like symptoms.

Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Anslutning av vindkraft till ett svagt nät i Tidaholm

Vindkraftverk ansluts idag i snabb takt till elnät runt om i världen. Elnäten är ofta inte tillräckligt dimensionerade på platser där vindkraftutbyggnad är lämplig vilket leder till ett behov av nätförstärkning. Förstärkning sker konventionellt genom att övergå till en högre spänning, något som kan vara förenat med stora kostnader och ledtider. Bland annat därför har en filosofi med beteckningen smarta elnät uppstått, som handlar om hur elnätsystemet ska se ut när det är mer anpassat till de nya energikällornas karaktär och samtidigt medför ett mer effektivt totalutnyttjande. För vindkraftverk kan det då handla om att i högre grad än idag reglera produktionen och understödja nätet, t.ex.

Kylfläns till förbränningsmotor hos radiostyrda tävlingsbilar

Inom Radiostyrd Bilsport tävlas det med ett antal olika klasser som drivs av 2-taktsförbränningsmotorer. Dessa blir mycket varma och måste kylas av. Det sker med hjälp av enkylfläns som är monterad ovanpå förbränningsrummet, och som kyls av fartvinden.HP Hobbyprodukter har frågat oss om vi kan hjälpa dem att ta fram en egen kylfläns åt dem.Eftersom det ofta förekommer ovarsam behandling i tävlingssammanhang, är det ett krav attkylflänsens ska tåla detta. Den måste även avleda värme från förbränningsrummet, motorblocketoch övriga motorkomponenter effektivt. Ett önskemål är att kylflänsen ska ha ett unikt utseende,så att den är lätt att känna igen ute på banan.Arbetet har inriktat sig på prototypnivå.

Migration av distribuerad relationsdatabas för lagring i webbläsare

An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers? browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess.

Organisationskultur i fusion : en studie av neurologiska kliniken på Karolinska Universitetssjukhuset

Mergers and Acquisitions have become more and more in common knower days among the companies. Factors that might influence could be such as power of competition or it could even be the aim of new strategies of the company. In mergers is it not only the buildings and the physical objects that is put together, also the human beings within the organization are put together. Each person contributes to the culture, which makes the situation more complicated. In making a merger successful, it is important to pay attention to the organizational culture.

En studie av höghusbyggande med avseende på stomsystem och lastpåverkan

Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.

Energideklarationer - Marknad och Kundkytta

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
