The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

Detta examensarbete berör värme och ventilation inom arkitekturen. Examensarbetet kommer att visa hur värme- och ventilationssystemen sett ut och utvecklats med tidens gång. Med hjälp utav framtagen information kommer tre koncept att skapas som resultat av att ha kombinerat olika konceptframtagningsmetoder. Målet är att komma fram till en slutsats om hur det optimala huset bör se ut för att värme- och ventilationssystemet ska vara lätt att underhålla och använda samt vara så pass energieffektivt som möjligt samtidigt som det fullgör sitt syfte. För att få ett bra resultat så uppmärksammas alla möjliga faktorer som på större eller mindre skala har inverkan på systemen.

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.

The aim of this work is to give a broader and more nuanced picture of the use of locks and keys during the Iron Age, in particular the late Iron Age, in the Lake Mälaren region. This has been done by comparing two buildings: the hall on Helgö and the living quarters in the garrison on Birka. Here we can see two very different areas where locks and keys were important parts of the daily life. The study also includes a typology of padlocks based on the findings from the same places as the building study and their surroundings..

En energikartläggning är en rapport som sammanställer energianvändning i en fastighet eller del av en byggnad. Med hjälp av olika mätningar och beräkningar kan man visa vilka delar i byggnaden som kräver mycket energi, både värme och el. I denna kartläggning ingår utredning av energi till ventilation, radiatorer och värme, vatten, kyla, belysning samt elförbrukning och analys av klimatskalet. Utifrån denna kartläggning kan man sedan utarbeta en åtgärdsplan som kan leda till förändringar och ombyggnationer och omprogrammeringar som sparar in på energianvändningen. Denna rapport innehåller en energikartläggning av Lagret 8 i Skellefteå.

This work is about getting to know tufting as a technique and to design tufted products for home furnishing.It all began in Finland, where during springtime 2004, I got in contact with the technique oftufting for the first time. A very pleasant meeting that resulted in two carpets and a longing to continueand learn more. It was then that an idea for my final project started to take form. My wish was to designtufted ?floor jewelleries? and cushions.I made a base for my project during a design project in autumn 2004.

The purpose of this essay is to examine if the municipality has a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project.In Karlstad there is now (2006) a large building project in form of a shopping mall. This project is in its final stage of completion and offers me a suitable case to examine. To undertake the purpose of the essay, the following research question is formulated:Do the municipality have a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project as the Mitt I City project?In an attempt to examine the project and the planning process, three themes are applied. The first theme derives from the hypothesis that the part that initiate the process gets the upper hand as future discussions are taking place in relation to the original ideas.

In the post-war era many European countries were recovering from the ravages of the bombings of the second world war destroying whole countries. Sweden being neutral was spared the destruction of war but instead we demolished almost as much housing all by ourselves. A social program was modeled to modernize the country and to drag the swedes out of poverty by building one million apartments in just ten years and demolishing the old, dilapidated working-class neighborhoods. The traumatic events of the demolition of large areas of both the central and the outskirts of most Swedish cities is still very much present in the collective memory of people today and the new modernistic districts are still paying the price of that, more than fifty years later. Today these modernistic districts are in need of repair, and they are often homes to groups alienated from society making their reputation even worse.

This report will present an energy efficient building in the centre of Kalmar city. It willbecome energy efficient because of the worldwide goal to reduce our energy using in ourbuildings.The values of architecture have been given a great part in this report. The building is supposed to be placed in Kvarnholmen in a unique environment in centre of Kalmar city.Because of the placement it is very important to show respect to the surroundings and the history of Kalmar..

Till år 2020 har EU satt upp mål om att sänka energianvändningen med 20 %. År 2013 står fastigheter för 40 % av Sveriges totala energianvändning och är på så vis en starkt bidragande orsak till den höga energianvändningen. Som ett led i detta arbete måste energianvändningen i fastigheter minska.Halmstad Kommun har ett stort fastighetsbestånd, där det äger och förvaltar många förskolor. De förskolor som utvärderas i rapporten är Trollbergets förskola i Söndrums Kyrkby och Askens förskola i Oskarström.  De här förskolorna har enligt fastighetsägarna (Halmstad Kommun) en betydligt högre energianvändning än vad som var projekterat.För att undersöka energianvändningen i förskolorna Asken och Trollberget i Halmstad Kommun har det gjorts beräkningar, besiktningar samt enkätundersökningar med personalen. Energiberäkningarna visar att både Asken och Trollberget förbrukar mer energi än vad som är rekommenderat av BBR.

Air tightness in new buildings has been discussed for several decades. But the knowledge in the subject is low. With tougher requirements from the Swedish government about energy consumption for a new building required competences how these shall be met. It's not only the thick mess of insulation that are important, it's also the air tightness. This report is about air leakage in Swedish houses.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
