Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Optimeringsflöde av modelleringsprogram vid broprojektering : Analys av de tre modelleringsprogrammen Tekla Structures, Revit 2013 och Rhinoceros

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus

The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

Fastighetsunderhåll : Arbete med underhållsplaner i stora fastighetsbolag

Background: The standard of living should be the same for everyone, whether the apartment is placed in an old or new building. The residential properties that were built from 1965 until 1974 is now beginning to become old and in need of restoration. The financial crisis during the nineties contributed to the lack of maintenance on the buildings in Sweden. As the public buildings gets older more and more defects occurs. The coordination and maintenance will therefore have a more significant role in the housing company ?s work.The increasing interest about how old a building can be, attract much attention.

Återuppbyggnad av en kollapsad stat - En fallstudie av återuppbyggnaden av staten Afghanistan

The purpose of this thesis is to explore and analyze the processes and efforts involved in rebuilding the war-torn state of Afghanistan. The examined period span from the fall of the Taliban regime in 2001, to the elections in 2005. This period, commonly known as the Bonn-process, sets out the initial time for the reconstruction of the state.A theoretical framework, which considers the necessary mechanisms for successful state-building, will be used to analyze Afghanistan's re-building process. The mechanisms include the prerequisite of a stable security environment, emerging from a cease-fire, together with the development of a well-functioning economy, re-introduction of rule of law and rejuvenating civil society.The failure to establish a secure environment has had a devastating impact on all analyzed aspects of the re-building process. It is therefore crucial that the international society continuing to assists the Afghan government in its efforts to strengthen its capacity, in order to improve the security situation.

Energikrav i upphandling av bygg- och anläggningsprojekt

The building and plant sectors represent a large part of Sweden?s energy use. Putting energy requirements in public procurement as a tool for reducing energy consumption in the building and plant sectors is therefor an opportunity that operators can take advantage of. The aim of this thesis was to map the energy requirements in procurement that operators in the public sector use today in building and plant projects. The analysis was made with respect to if the energy requirements corresponded to the parts with large energy use in building and plant projects and also in which way energy requirements in procurement are written in the contract.

Värdefull eller värdelös? - Kulturhistorisk värdering och färjestationen i Helsingborg

This essay in historical archaeology deals with cultural-historical values of buildings and inthis case the old train- and ferrystation in Helsingborg. The building has from the day of itsopening in 1898 been exposed to threats of demolition since its original purpose was as atemporary building with intension of being replaced within a couple of years. After havingseen two World Wars, eventhough Sweden never participated, and the ferrytraffic with its upsand downs the station was an important part of Helsingborg. All the ferrytraffic over the straitto Denmark was handeled by the old train- and ferrystation untill 1955, when a competativeferrycompany was built close to the old station. After a hundred years of service the oldstation was closed down when a new station was built i Helsingborg in 1991 with theintension of gathering all travelers in one building.

Miljöcertifierade byggnader Värde för investeraren

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Förbättring av Egenvärmehus : En fallstudie av ett flerbostadshus, Kv. Fyrtornet

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

Utvecklingsanalys av installationssystems montering vid industriellt träbyggande : Värme, vatten, ventilation, el och avlopp

The industrialized timber housing process is capable nowadays to build multi-storeyhouses since fairly new changes in the Swedish regulations where made after theadmission of the European Union in 1994.The industrialized process moves parts of the construction process into a highlyeffective factory where 3D-volumes of the building are prefabricated beforetransportation to the building site for assemble.The assembly process is relatively effective compared to the completion of thebuilding service system and this is therefore the main focus in this thesis. This thesisattends problems with completion of the building service system, and thereforedemarcates from other aspects, such as technical and economic aspects, of thebuilding service system.The degree of completion of the flats differs from completion of the connectivepassages, for example hallways, in a way that suggests a need for further investigation.This thesis includes analysis of the possibilities to increase the prefabricatedconnective passages, to the extent of containing building service systems.An increase of the prefabrication of the building service system has a greatdevelopment potential, even though some restraining factors need to be solvedbefore implementation.This thesis was made in collaboration with two of Sweden?s leading companies on themarket of multi-storey industrialized timber housing, Moelven ByggModul AB andLindbäcks Bygg AB..

Uttorkning av lera : Orsaker och följder

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

SANNINGENS ÖGONBLICK En komparativ undersökning av ett stadsbiblioteks och en byggvaruhandels arbete med att möta sina besökare

The purpose of this thesis is to discuss how a Swedish public library approaches their costumers. I will show how a library interacts with their costumers compared to a business, which has a different economic work frame, a building materials supplier. My aim is to pinpoint differences and explore new methods for the library in order to improve their service.The theoretical frame of the thesis is based on Richard Norman's notion the Moment of truth. The moment of truth is the moment when a business has to convince their customer that they offer both the product, proficiency and service that the customer needs. Service encounters at two organizations have been observed and their differences and similarities compared.

Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden

The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.

Bedömning av loggbok : Bedömning av loggbok med en uppgiftsspecifik matris

The purpose of my independent work was to develop and test a task-specific assessment matrix to the students writing logs that occurs in connection with their APL (workplace-based learning). The matrix is based on upper secondary school subject plan House building from The Swedish National Agency for Education and the four courses House building process, House building 1, House building 2 and House building 3 - conversion. Due to the matrix structure, I used the example matrix of Malmö University. The task-specific assessment must both serve as a guide for students in the implementation of the log writing, and in the evaluation of the assessment work. Both students and teachers then get a common assessment tool for evaluation.
