Det norska energideklarationssystemets konsekvenser för äldre byggnaders karaktärsbärande värden
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.
Taxed Enough Already : en analys av Tea Party rörelsen i USA
The aim of this thesis is to describe the rise of the Tea Party movement in the United States. By using a known theory within social movement studies, the political process theory, this thesis look into the factors that could have played a role in the rise and fast mobilization of the Tea Party movement. The political process theory consists of three parts and hence looks into both the political structure of, in this case, the United States, how mobilizing structures have been used and into the cultural framing used by the Tea Party to create their identity. In order to bring structure to the thesis, the three theory parts have been transformed into analysis models. These give a very good idea of all the factors that could have played a part and therefore also a good way to describe the rise of the Tea Party movement.The research confirm what the political process theory says, that the Tea Party movements rise came at a time when there were a mix of factors at play, both structural and cultural, creating an opportunity that the Tea Party took.
En studie av höghusbyggande med avseende på stomsystem och lastpåverkan
Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.
Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?
This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.
Erfarenheter från flerbostadshus som passivhus : En handflata och sex värmeljus
All new households were to be constructed with "near zero energy house standards" (NZE-house) by the year of 2020. The ambition to construct energy-efficient buildings had to increase rapidly in the spring of 2013.The purpose of this report was to increase the interest for building contractors to construct apartment buildings with passive house standards. By locating and evaluating experiences from an existing passive house a case study including interviews, field visits and document analysis was made. Research of literature regarding other passive houses in Sweden also helped to answer the following questions:- What positive and negative experiences have the study of the passive house meant to the involved stakeholders and residents?- What improvements can be made based on identified experiences?- How can an apartment building be designed as a passive house based on possible improvements?By collecting good and bad experiences, as well as improvements and potential design proposals, a diagram was created designed as a tool for developers when constructing apartment buildings with passive house standards.
En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion
Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in
modern buildings. In modern contemporary construction, large glass panels are often the ideal because
of increased light inflow and for architectural purposes. However, this can generate several negative
effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that
window shutters could have accommodated historically.
This thesis identifies a lack of knowledge about interior window shutters in the Swedish building
stock.
Tätortsklassificering utifrån servicebredd och servicegrad : En klusteranalys av Sveriges tätorter
Statistics Sweden is an administrative agency that delimits built-up areas and produces statistics regarding them. The statistics provide information about the area of the built-up areas, their population number, number of gainfully employees working in the built-up areas, and of buildings. Now Statistics Sweden wishes to extend such statistics by producing a measure regarding how well developed the service is in each built-up area.This study is a contribution to this statistical improvement work and the purpose is to ? by employing geographical information systems and cluster analysis ? classify the Swedish built-up areas according to 1) service width and 2) service degree. A particular built-up area has a high service width if it has many different service functions, such as pharmacies, schools and grocery stores.
Lönsam smågrisproduktion : en fallstudie
The purpose with this work is to investigate the cost to produce piglet in a case study
company. The starting point is going to be the agriwise (www.agriwise.org) calculation which
I am going to change and adapt to the case study company. To day the pig market is bad but
we have probably reached the bottom. The market has started to rise. It is no business to
produce piglets today.
Redovisning av dörrar och dörrpartier i offentliga lokaler : Problem och förslag till förbättringsåtgärder
Today, the requirements on doors and door sections in buildings are often many andtightly restricted. Especially in public buildings, the requirements for safety andfunctionality must cover the needs of larger groups of people. These strictrequirements have often led to doors and door sections in public buildings being verycomplex and difficult to correctly install without any complications.This diploma work has been carried out in cooperation with Werket Architects,which estimates a high percentage of flaws regarding aforementioned components, inprojects of the type described. The company therefore wanted to investigate howthey could develop their remit in door production, which is the projection and designof blueprints. By taking part of installers opinions on how they want the blueprints ofdoors and door - sections to be designed for the best installation possibilities,develop¬ment areas, and to some extent improvements regarding the company's useof accounting techniques, could be provided to the company.The study shows, among other things, that there is a possibility of development in thefunctional descriptions that entail the doors' fitting components.
Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder
The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..
Höga hus med deformerbara fundament på pålar : Pålkrafters avvikelse visavi klassisk teori samt förskjutningar beroende av vindlast
When forces in foundation piles are calculated according to classic theory, thefoundation are assumed to be infinitely rigid which means that the foundation will notbend. High buildings need their whole width to be stable and use the ground floorwall as a foundation. But when, for example windows are needed in the ground floorwall, the stiffness of the foundation decreases which change the forces in the piles. Inthis report the difference of pile forces versus classic theory has been analyzed, and ifpile forces can be calculated as in classic theory. Further on, the effects of the wallmovement were analysed and how the buildings crack safety would be affected by themovement at the ground floor.
Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling
Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
Energieffektivisering av flerbostadshus i miljonprogrammet
This thesis has been written with our society?s current energy-situation in mind.Although it only deals with one particular block of buildings, the solutions and suggestions presented herein are quite applicable on other objects of the same type.This thesis is intended to be used as a guideline for energy-preserving projects in general, with an eye to buildings erected during the Swedish ?million-programme? in the sixties and seventies.The paper starts with the acquiring of all necessary blueprints and technical specifications. It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..
Brandsäkerhet i ett småhus
This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.
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.
