Tätskikt i klimatskal : En studie av byggentreprenörers arbetssätt
As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.
Uppföljning av träbyggnadsprojekt inom Växjö kommun
Ett sekellångt förbud mot att bygga hus med trästomme högre än två våningar har gjort att värdefulla kunskaper om träbyggandet gått förlorat samtidigt som andra material istället etablerat sig på marknaden.För utvecklingen av flervåningshus i trä har Växjö blivit en förebild för andra städer i Sverige och resten av världen. Med denna studie vill författarna skapa en uppfattning om var i utvecklingen vi står idag samt tillvarata erfarenheter från fyra representativa projekt.Målet har varit att ta fram faktorer i produktionsprocessen som påverkar tid, kvalitet och ekonomi för flervåningshus i trä. Dessutom har det undersökts i vilken grad och på vilket sätt erfarenheter från tidigare projekt omsatts i senare projekt.Arbetet resulterar i ett antal punkter som är viktiga att ta ställning till vid en byggnation av flervåningshus med en träbaserad stomme. Dessa punkter berör bl a vad som behöver beaktas vid hög prefabriceringsgrad, varför och hur väderskydd bör användas samt hur sättningar påverkar en träbyggnad. Utvecklingen är starkt beroende av kontinuitet och av att fler hus av denna sort byggs.
Brandskydd av stålkonstruktioner : Lathund för brandskyddsdimensionering av stålprofiler
This bachelor thesis covers fire protection methods of structural steel and the aim is to develop an information tool designed for inexperienced structural engineers. The information tool covers basic fire protection methods and the general way to produce a fire resistance for structural steel. The layout of this information tool is a simple folder that contains information about the most important steps when producing fire protection for a steel structure.The thesis starts with a general overview of the fire protection needed in buildings to fulfill national legislative and regulatory requirements. To get an understanding of how steel components behave during the influence of fire, a brief overview is presented of the material properties of steel. This chapter also contains a review of previous research in the area.
Allergirond i skolan - Skolpersonalens upplevelser avseende astma- och allergiframkallande faktorer på tio skolor i Malmö - en kvalitativ studie
Syftet med denna kvalitativa studie är att på tio skolor i Malmö undersöka skolpersonalens upplevelser utifrån de nio teman Allergirond i skolan utgör. Ökningen av astma och allergi har under de senaste decennierna varit alltför snabb för att kunna sättas i relation till förändringar i det genetiska arvet.I stället har ökningen samband med förändringar i miljö och livsstil, antingen genom ökad kontakt av allergener eller genom minskad kontakt med faktorer som tidigare skyddat mot allergiutveckling. Till följd av detta har ett tvärsektoriellt samarbete kring allergifrågor inletts i Malmö. I detta samarbete har Malmö skolor erbjudits att ingå i ett projekt som har till syfte att öka kunskapen kring astma och allergi samt att aktualisera egenkontrollen. Vi har i uppdrag av Miljöförvaltningen i Malmö fått möjlighet att introducera och genomföra allergirond på tio skolor i Malmö genom intervjuer av skolpersonal.
Flyttprocessens påverkan på identiteten ? utveckling eller avveckling? : En fallstudie kring flytten av Hjalmar Lundbohmsgården i Kiruna
The purpose of the thesis is to investigate and analyze how three different actors linked to the urban transformation in the city of Kiruna, in this case LKAB, the Municipality of Kiruna and the County Administrative Board of Norrbotten, believe that the identity of a historical monument that is marked cultural heritage is affected by future relocation. The second part of the study is to investigate the impact the building might have on the city in the future. This study is based on the relocation of Hjalmar Lundbohmsgården.The study is based on a qualitative approach in which five informants from the three actors were interviewed. The interviews have been analyzed through thematic analysis, where a combination of theoretical thematic analysis and empirical thematic analysis was used. The result shows that the new location of Hjalmar Lundbohmsgården is preferred to be in a suitable context close to other cultural buildings. All informants agree that accessibility is a fundamental element in, which a synergistic effect is an increase in visitor numbers.
Invasivt ventilatorbehandlade intensivvårdspatienter : Effekter av tidig mobilisering - en systematisklitteraturstudie
Patienter som läggs in på intensivvårdsavdelningar blir ofta sängliggande en längre period. Invasivt ventilatorbehandlade patienter blir inte alltid mobiliserade som de borde. Immobiliseringen hos patienterna har en rad negativa effekter på kroppen, men att låta mobiliseringen bli en prioriterad åtgärd kan vara utmanande för intensivvårdssjuksköterskan och teamet kring patienten. Syftet med denna studie är att beskriva effekter av tidig mobilisering för invasivt ventilatorbehandlade intensivvårdspatienter. Metoden som valts för att genomföra studien är litteraturstudie.

Analys av Termodeck som ett uppvärmningssystem : En jämförelse mellan uppmätt och simulerat värde samt analys om skillnaden för husets energianvändning
Ett passivhus är byggt av stomentreprenör företaget Strängbetong i Vara med ventilation och uppvärmning i samma system som kallas för Termodeck. Uppvärmningen sker genom att tilluft från ett FTX-aggregat förs igenom håldäcksbjälklag som värmer upp bjälklaget. Med det erhålls ett ?värmegolv och värmetak?. För ett sådant system behövs en byggnad med tung betongstomme.Energibalans beräkning har gjorts med IDA program och schablon värden från olika kravspecifikationer som visar simulerade värden.
Arkitektonisk kvalitet med fokus på skönhet ? En fallstudie av hyresgästers betalningsvilja för skönhet i Garnisonen
In the Real Estate market there are a large number of commercial properties with offices. As acompany or business you are faced with many decisions when choosing your office space.This bachelor thesis examines the concept of architectural quality with focus on beauty and itsvalue for office tenants. The ambition is to find out if beauty is a decisive factor in theselection of office and if there is a willingness to pay for it.The selected question is studied in a case study of Garnisonen where tenants, a propertyowner and an architect are interviewed, all with connection to the examination object.Garnisonen is well suited as a case study because it is Stockholm's largest office complexwith buildings from three different architectural eras. Tenants in the survey represent allarchitectural styles and have different industry affiliation.As a theoretical framework a literature study is presented where the importance of beauty forthe individual, the built environment and society are treated, and also how the office can beused for branding purposes. The interviewees? views of beauty and their opinions on beauty atwork in Garnisonen are presented in the results.
Byggnads- och investeringskostnader : Robotmjölkning eller konventionell mjölkning?
This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south
of Eslöv in Skåne.
While my family for some time have thought about building a new milkingstable with
AMS(Automatic milking system) I decided to compare the AMS with a conventional
milkingstable. We are abit concerned about how many cows we should have in the new
stable. Because of that I calculated with two different number of cows.
I have compared three different types of milking stables:
One alternative is 180 cows milked in a double eigth hearing bone milking stable.
The second alternative is 128 cows milked with two DeLaval VMS-robots.
The third alternative is 171 cows milked with three DeLaval VMS-robots.
One salesman from DeLaval and one salesman from A-betong helped me to get marketprices
on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs
labour is included.
The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program
with predicted costs. The calulations from the program showed that the price in the milkingpit
system was 51 000 sek per cow.
Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare
Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.
Projektledning i virtuella teams - Förtroende, gemensam förståelse och groupwares
Virtual teams are teams where team members don?t sit and work in the same place, they canwork in different countries, cities and buildings. It?s not the distance between team members that defines a virtual team, it's the extent to which the team is dependent on information technology to communicate and carry out a task. Virtual teams is becoming more common in organizations, to use virtual teams organizations can reduced time and travel costs and create a larger knowledgebase.A project manager for virtual teams faces many challenges, they have to build trust with and among team members they rarely or never meet, create a common understanding of project objectives and manage the challenges that culture and information technology creates.
Kunskapshus eller offentligt vardagsrum? En undersökning av Lunds stadsbiblioteks ombyggnad
In this study my aim has been to discover what connections can be made between the way of creating a library building and the general values concerning the library activities and the library users. What kind of ideology could possibly be reflected in a library room? My study includes two different parts. First of all there is a theoretical section based upon literature relevant for the subject. Here I try to focus on the libraryÕs role in society as a public room.
Energianalys mellan programmen IES (Integrated Environmental Solutions) och Enorm
An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.After finishing the study sketch the modeling of the nursery school began.
Metodval i projekteringsfasen : Bostadshus Ljusbojen 1
This major project in Building Engineering has its focus on inquiring into what methods has been used in the planning process of the residential buildingLjusbojen 1. This project has been conducted in cooperation with Kadesjös Ingenjörsbyrå AB, an engineering contractor firm which also acts as the property developer. Initially several different general methods for planning residential buildings have been presented. After the methods from the process of building Ljusbojen 1 has been analyzed compared to the general methods presented in part 1. This shows what the determining factors are during the planning process; factors such as cost, quality, time management, know-how and environmental issues.
