Beräkning av baslinje för Performance Contracting med linjär regression
Energiutvecklingsprojekt är idag mer aktuella än någonsin. För att kunna genomföra så stora projekt som hela fastighetsbestånd, och samtidigt ta hänsyn till lagen om offentlig upphandling har affärsmodellen EPC, Energy Performance Contracting, utvecklats. I samarbete med SIEMENS AB Building Technologies har jag tittat på hur man kan garantera en viss nivå på besparingarna som genomförs. Denna garanterade besparing beräknas mot en uppställd baslinje, som är en beräkning av hur energianvändningsmönstret skulle ha sett ut med dagens förutsättningar om inga förändringar gjorts. Modellen med regression är noggrann och hjälper till att identifiera avvikande användningsmönster..

Västergarns kammar : en fallstudie av Västergarnskammarna från seminariegrävningarna mellan åren 2006-2010
During the years 2006-2010 Gotland University conducted seminars excavations in Västergarn parish on Gotland. Inside the wall a total of six house foundations have been found and a total of 127 combs have been registered. This thesis is based on a material study of the 127 registered medieval combs. The purpose of this thesis is to analyze the combs and with their chronology illuminate in which period the society of Västergarn was active. And also to find out what the material remains can tell us about the place and its people.
Tätning eller ventilering mot fukt på kalla vindsutrymmen
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
Limträstomme till hallbyggnader : Utformning och dimensionering av momentstyva ramhörn och 3D-modell framtagning
Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.
Sensory nerve conduction studies in young adults for the expansion of a reference material
Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
Vesper : möbler vid sidan av tiden
I den här rapporten redogörs för processen vid framtagandet av det första objektet i möbelserien Vesper. Författarens tillika formgivarens tankar kring olika materials narrativa förmåga i relation till en betraktares förförståelse, föranleder en formgivningsprocess som resulterar i ett arbetsbord där material och symbolspråk tänks förmedla sköna värden. Uttryck av varaktighet och omsorg i en kontext med tillfällighetssyndrom..
Slöjdens hårda och mjuka material alltmer sammansmälta : Samarbete inom slöjdens olika material, kan det utveckla ämnet?
Syftet med studien var att undersöka om slöjdlärarnas olika utbildningar spelar roll för samarbetet inom slöjdens mjuka och hårda material och hur ett sådant arbetsätt kan se ut. Undersökningen har även försökt få svar på om eleverna blir mer motiverade av ett arbetsätt där materialen blandas. Dessutom har arbetet handlat om att ta reda på om det finns ytterligare faktorer som spelar roll för samarbetet inom ämnet slöjd. Genom studier av tidigare kursplaner för ämnet i skolan och för slöjdlärarutbildningar har jag fått en historisk tillbaka blick för vad som ingått i både slöjdlärarutbildningar och i undervisning för eleverna i skolan. I mitt sökande efter svar har 8 slöjdlärare intervjuats som läst mot både tidigare och nuvarande läroplan för grundskolan och som har examen från utbildning med behörighet i ett eller båda materialen.
Förutsättningar inför detaljplanearbetet - Hur påverkar detta processen?
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..
Historiska museet och Tegnérsplatsen i Lund - Kulturträffpunkt eller anonym museimiljö
Detta examensarbete är ett förslag till en förändring på området Historiska museet och Tegnérsplatsen belägna i Lundagård, Lund. Historiska museets intryck som museum är inte det högst värderade bland Lundabor - för många förmedlar byggnaden snarare känslan av en förvaltnings- eller institutionsbyggnad. Miljön anses varken vara inbjudande eller en museimiljö. Den intill liggande Tegnérsplatsen, belägen på museets baksida väcker ännu mindre intresse hos allmänheten. Det är en folktom plats utan sittmöjligheter eller liknande.
Tegel och klinker - keramiska material på mark :
Being an architect I create spaces with roof, walls and fl oor. The availability of the essential materials to create such spaces is practically unlimited. The materials also play a significant part to the character of the created space. I hope to contribute to the general understanding of materials as elements in the design of urban spaces by having intensely explored one specific material in depth, pointing out its bad and good qualities. I am of the opinion that the reason for choosing a material shouldn?t be because of a shortage of knowledge, facts or references, but what character you want for the room.
When travelling across Europe, it sometimes feels like clay paving is everywhere, but back in Sweden it is almost unseen of in modern landscape architecture.
Normkritisk pedagogik på normativ grund : En analys av arbetsmaterialet Möte med människor från andra kulturer
The aim of this study has been to analyze how society is constructed in the workbook Möte med människor från andra kulturer, a popular material within the ?cultural competency? industry. The analysis has largely been carried out from the perspective of a pedagogy against oppression as it has been outlined by Kevin Kumashiro. I have found that the material combines discursive movements, which in complex and hybrid ways deconstruct, decenter, recenter and reproduce stereotypes and norms, through its normative language and pedagogy. A language constructing culture as cleanly demarcated, static and homogenous.
Fuktegenskaper hos Quartzene impregnerat med salter
Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.
Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material
With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
Varför uppförs så få bostadsrätter med passivhusstandard i Sverige? : En fallstudie mellan ett passivhus- och en konventionell fastighet
Abstract Background: In 1997 the Kyoto Protocol was signed, it?s an international agreement which is aimed to reduce greenhouse gas emissions. Sweden's goal is to reduce energy using in buildings with 20 percent by 2020 and 50 percent by 2050. This is a comparison with levels from 1995 (Glad, 2006). For Sweden to be able to reach its goals, they need to construct more low-energy buildings (Åhman, Wahlström & Lundblad, 2010).
