Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.

Det uppätna monopolet : Initiativ, inflytande och resurser vid planeringen av kvarteret Druvan genom projektet Mitt I City

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.

XM982 Excalibur : användbar i krig och konflikter?

Denna uppsats behandlar precisionsgranaten XM982 Excalibur. Syftet med arbetet var att öka kunskapen inom Försvarsmakten avseende Excalibur inför ett nyttjande av granaten i krig och konflikter.Syftet var också att definiera faktorer som är viktiga att tänka på vid nyttjandet av Excalibur i krig och konflikter.Frågeställning jag ställde upp för detta arbete är: Hur kan XM982 Excalibur användas i krig och konflikter?För att kunna svara på frågeställningen så besvarades tre olika delfrågor.De tre delfrågorna är:Vilka tekniska och taktiska faktorer framkommer genom information från industrin?Vilka tekniska och taktiska faktorer framkommer genom information från Försvarsmakten?Vilka faktorer framkommer genom information från nyttjandet av Excalibur av USA i Irak?  Metoden som användes var litteraturstudier samt intervjuer av personer som arbetat med utveckling av granaten. Varje frågeställning avslutas med en diskussion där de olika faktorerna som framkommit diskuteras.

Energieffektivisering av arbetsbodar på byggarbetsplatser

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

Fjärrvärme - ny lokalisering av kraftvärme i Enköping

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Att låta tusen blommor blomma. - Lärares syn på relationens betydelse för elever med koncentrationssvårigheter.

The aim of this bachelor's thesis is to investigate how teachers view the way they build their relationships towards students, both in general and, more specifically, towards those students with some type of attention deficits. The focus of this thesis has been on how great an importance teachers place on this relationship. Especially when it comes to working with students with attention deficits. We also want to know to which extent this relational perspective is rooted in teachers' practice. The theoretical basis of this study is the relational perspective formulated by Aspelin and Persson (2011).

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Grön urbanitet - en teoretisk reflektion samt praktisk illustration för Varvsstaden, Malmö

Hur kan vi planera och argumentera för en mer integrerad och intensiv urban grönska i våra allt tätare städer? Vilken viktig roll spelar grönskan i förhållande till dess strukturer, funktioner och upplevelsevärden för stadsmänniskan? Vilka möjligheter ryms inom dagens stadsplanering för att synliggöra och maximera också den täta stadens småskaliga och med bebyggelsen socialt och funktionellt komplext sammanvävda grönskor? I ett personligt teoretiskt reflekterande utifrån relevant litteratur undersöks möjligheter och begrepp i relation till en grönare urbanitet. Syftet är att lyfta fram behovet av en utökad och mer nyanserad vokabulär som bättre kan motsvara morgondagens behov av att beskriva och planera för ett finmaskigare och småskaligare grönt nätverk också inne i den täta staden. De i den teoretiska reflektionen funna strukturella, multifunktionella och upplevelseladdade gröna begreppen prövas därefter explorativt i en platsstudie med praktiska illustrationer, analyser och karteringar för området Varvsstaden, Malmö. Som resultat nyanseras, vidgas, urbaniseras, funktionaliseras, laddas, systematiseras och omstruktureras innebörden av begreppet grön urbanitet..

En skattemyndighet : Balans mellan maktutövning och relationsbyggande

Background: Power by force and threats used to be the common way to collect taxes, but this procedure is today completely different. It?s now more about building a mutual relationship and with help of laws and controls steer citizens and companies to pay the tax they owe. Thus the way to collect taxes have changed over the years, the collecting of taxes aren?t a popular task to do.

Kirunametoden-Jämförelse emot en konventionell injusteringsmetod

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Investeringskalkyl baserad på ett flerbostadshus energiprestanda

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.
