The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

Avancerad program- och funktionsstudie i form av multi-use-byggnad uppbyggd kring ett badhus i urban miljö i stadsdelen Fenway i Boston. Byggnadens huvudteman är "den klättrande parken" och "bakom muren". Det förstnämna genom att det befintliga parkrummet invid byggnaden tematiskt ges en förlängning in i byggnaden och trappar sig uppåt i badets olika nivåer för att mynna i en södervänd takträdgård och soldäck högst upp. Temat kring muren uttrycks genom en massiv långsträckt byggnad mot gatan som skärmar av det södervända badet från den trafikerade gatan. Mot parkens lummiga träd vänder sig ett tredje objekt i form en glasad byggnad i fyra plan med café/restaurang och bibliotek med läsrum och studieplatser..

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

I?ve previously been working with patterns for wallpaper and wanted to try anotherapproach.I wanted to use a strange story as a base to develop a wallpaper collection from. Theaim was to make a collection that is more than wallpapers. The seed to this idea Igot from an article about mysterious deaths among birds in Chicago published inmetro. They had flown into a large building.

?A culture center should be visually welcoming as well as attract a diverse range of visitors with different backgrounds.? This was the client?s request for a new cultural center in Nairobi. The location is in the heart of Nairobi?s industrial area, near several existing buildings that are already in use by the culture organization known as Go Down. I have chosen to keep most of the existing buildings and to use my new building as a complement for the desired program.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

How can a multi project organisation use Wiki to support improvement of knowledge management and project evaluation to become a learning organisation? The main purpose of this thesis is to give management and employees a better understanding of how Wiki supports knowledge management and project evaluation. The second purpose is to illustrate possible difficulties and pit falls that comes with the implementation of Wiki based learning. The theoretical framework initiates by explaining multi project organizations, then describes Argyris and Schöns theories about organizational learning and learning organizations. The second half of the theory chapter brings up theories about important areas for a learning organization.

The story of the forest - A folded textile wall for flexible rooms in public spacesIn the story of the forest the dragonfly is spinning yarn shiny as the sun. In the story of the forest almost everything can happen and almost everything is also happen there.Inspiration from Lennart HellsingThe goal in this exam work was to create a calm, playful space for children in public spaces. A place where children can hide and relax without being disrupted by the surrounding, a place where their imagination can grow and take place. The goal was also to make a flexible space for public spaces that could be used in different ways. Today many libraries want to be more than a library, they will work as a meeting place and you can find several activities to join in.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

By conducting a text analysis this study analyzes possible similarities in the portrayal of story characters between historical Norse myths and contemporary film productions. The chosen historical texts are two stories from Norse mythology which render a myth about Thor and a giant named Hrunge as well as the myth Trymskvädet. The selected movies are two of the comic company Marvel?s productions about super heroes ? Thor and The Avengers. Different categories that this study compares are how the characters are defined by their possessions or artefacts, the actions and the choices which the characters make, and also how their relations, roles and origins are being portrayed.

On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

This report is about the exam project; Blomgren- a collection ofpatterns. During eight weeks I have from the family Blomgren, whowas my grandfather?s family with siblings and parents, produced fivepatterns for textiles into interior and space. In addition to thefamily as an inspiration, I have taken into account of the collection?sname - as a word and the meaning of the word.
