Full textThe last decades have the knowledge and techniques of sustainable building increased. The Report begins with the planning of the Swedish Eco-villages in the 70´s and how it has developed to today's low-energy building. Knowledge of heating systems, sewage treatment and building materials has been developed, how would an ecological residential area look today?The thesis is written for JM AB, Jönköping. An area at Ekhagen, east of Jönköping city center is chosen. An inventory of the land where made, which served as the base for the choices made in the planning of the ecological neighbourhood.The report investigates and illustrates how an ecological residential area may be planned, with today's knowledge combined with the Swedish Ecovillage-philosophy. Sewage treatment is an important part of the investigation and is explained thoroughly in the report. It is described how the contaminated water affects the environment and different systems for treatment of sewage are described. Analyses were made of two Eco-villages and two newly built residential areas and the result were compared given the differences in structure and choice of technology. Different sustainable techniques used for sewage and energy consumption were compared in the residential areas and infrastructure for good local environment was investigated.One issue specific for this area is noise problems. The noise levels at the site are exceeding the Swedish National Board of Housing, Building and Planning’s guidelines on noise levels. This is a problem that must be addressed properly and the report gives a suggestion of how this can happen. The final draft of the ecological residential area was developed out of two proposals. The main issues when planning the final draft were to place out the houses and roads after the terrain in order to limit the interference with nature, have consistent pedestrian and cycle routes through the whole area and that all buildings should be close to an green area. A separate treatment system for sewage and gray water, a simple system for waste treatment that separate swill, recyclable and household waste and a local treatment of the storm water through a wetland plantation, were some of the results of the investigations. The final proposal of the ecological residential area shows how roads and buildings can be adapted into the terrain and the noise level at residential patios can be reduced.

Full textThis thesis has been created to act as a basis for the preparation of a structural sketch of the property Nya Jägersro in Malmö. The thesis aims to create a planning concept that combines social and ecological sustainability by taking into account the specific characteristics of the site. Both the municipality and the property owner, the two most influential stakeholders, place great focus on sustainable development. The thesis examines two problems. The first is the property owner's separation of sustainability aspects, which through the reasoning that sustainability is created through interactions between different sustainability aspects can become problematic. The second is how Nya Jägersro as a place is affected by ideals of densification in order to build sustainably. To address these problems the purpose of the thesis is to develop a planning concept that combines social and ecological sustainability by taking into account the specific characteristics of the site. The theoretical framework consists of three theories that deal with sustainable site-specific planning and design for developing sustainable cities. The methods of data collection that have been used are site reading, literature studies and semi-structured interviews. The planning concept that is finally presented is referred to as JägersGro, which coincides in several respects with SMT's and Malmö Stad's agendas, but also deviates in some aspects. The biggest deviating factor in relation to SMT is that JägersGro assumes that sustainability consists of the combination of different sustainability systems. Another deviating factor from both actors is that JägersGro advocates the idea that the human impact on the natural systems should not only be reduced. Instead, sustainable districts are considered to be involved in regenerative processes in order to function in a balanced cycle with nature.

Full textSustainable development is one of the most relevant topics to deal with today. Especially in the area of urban planning it has become one of the most important questions to discuss. In Sweden we have for the last two decades seen several development projects that have set examples for sustainable and ecological living environments. In this essay we want to clarify whether sustainable and ecological living environments are going to be a norm in the future of urban planning. We have compared two development projects which have had great impact on sustainable urban planning, Bo01 in Malmö and Hammarby Sjöstad in Stockholm. These two projects have generated new innovations for a more environmental-friendly housing. We have compared their methods of working and results to a new, ongoing development project in the city of Helsingborg called H+. We have analyzed how they, compared to Bo01 and Hammarby Sjöstad, are working towards being a role model for sustainable urban development which is their goal (Stadsbyggnadsförvaltningen, 2008a:5). In our study we have reached the conclusion that in Sweden we are far from setting a norm for ecological living environments and that we need to elaborate better tools for planning and stricter demands from higher instances to reach this norm.

Full textWe are living today under climate threats which more or less will affect us all. In light of this, the construction industry has chosen to start conversion towards a more sustainable sector. Meanwhile, eco-houses and eco-villages, have been built up as an alternative way to stay healthy. The aim of this work has been to examine which choices developers / clients make during the planning of new housing. I have chosen not to look at energy, but focused on the way choices are made during planning of living apartments. To find out what choices could be considered as ecological / environmental a literature review was first made. To find out how the participant companies are choosing a survey was made. The responses were then compared with a fictitious company that would follow all advice literature meant was pro-environmental. The comparison was then made by a weighted scoring. It turned out that the companies got points that accounted for roughly 50 - 60% of the fictive. The survey also gave an overview of the choices they made and what they should be able to choose in order to build even more greener. The survey showed that the companies had the potential for it.

Full textAbout two years ago Laura and Erik Vidje began building their very own home just outside the city of Umeå. This building project would later turn out to become a unique and well noticed project with many involved and interested parties. The building project involved an entire estate with a residence, guest house, cold storage cellar and a PV (photovoltaic) system, and Laura and Erik were planning on doing as work as possible by themselves. What made this estate so unique was the choice of designing it according to the passive house requirements and at the same time be using unconventional and recyclable building materials, among other things was that the isolating material was going to be entirely made up of straw and the base plate would be made of recycled foam glass. The construction was going to be very well thought through, with large window facing south and a long roof overhang that will protect against insolation during summer but optimizes the insolation during winter. The walls would be built almost one meter thick to make great isolation and the entire building envelope were going to be extremely dense to minimize heat loss, but the most obvious unique attribute about the residence were going to be its round shape. By today the estate is nearly finished, but before a few technical instalments is executed the Vidje couple wanted to know what energy related needs the estate will have and how it will perform relative to official requirements. This specifically turned out to be only positive for them because the estate is now estimated to have a total need of electricity at about 23,1 kWh/m2 Atemp and year, which is almost one third lower than the standard value only for household energy. Also, the BBR-requirement for EPpet (primärenergital) turned out to be more than twice as high as the actual EPpet for the estate, which proves how well thought out the building project is and its high quality. In addition to this there were an interest in learning about knew technologies within sustainable housing and whether it was possible to implement these to their home. An important question to the Vidje couple was the possibilities regarding the PV system combined with a battery storage system. They would want to use as much of their own solar electricity as possible. What this project found out was that the 5 kWp (kilowattpeak) PV system would be able to cover around 70% of the estates yearly electricity needs, but that they would only be able to personally use no more than half of all that produced electricity. The rest would have to be sold and transferred out on the grid or possibly be saved in a battery storage unit. What became obvious while calculating the profitability of a battery storage system was that, with today’s electricity pricing, to sell the surplus PV production out on the grid will always be the most economically profitable option. Economic profitability was a reoccurring theme, especially for the PV- and battery storage system. Most of the focus regarding the PV system was between the options of renting it or buying it. In the end it turned out not to be a very significant difference 5 between the two options, the most decisive aspect when choosing will most likely be the difference of overall comfortability between the two. Analysing the PV system became a larger part of this project than expected when another request was to figure out how big of a climate impact the system would have compared to if the same amount of electricity was used from Umeå Energis grid. This analysis came up with probably one of the most interesting results of this entire project. Because PV panels require a lot of energy to produce and a large proportion of all panels in the world are produced in countries with a high carbon footprint, it means that PV systems has one of the worst climate impacts of all renewable energy sources. According to Umeå Energi 100% of their electricity are produced from renewable sources where solar power is not one of them. Because of this it turned out that during the 25-year lifespan of the PV system it would have more than twice the climate impact rather than if the electricity came from the power grid. The Vidje couple also wanted to know more about newly developed technologies related to energy, among things like V2G, self-sustaining homes, hydrogen energy storage, direct current grids and electric vehicle charging, to be able to establish whether any of these would be possible to integrate with their home in the near future. V2G, Vehicle-to- Grid, is still very much under development and therefore are not available for any person to use. Self-sustainability is definitely possible with today’s standards, but the only method that seems to work well enough is hydrogen energy storage which is still not very well established on the market and therefore also very expensive. Readjusting your home to work with a direct current grid is an interesting trend that some knowledgeable people have been doing lately, but it seems to be just that, something only a person who is interested and knowledgeable in the area are capable to perform at this stage. There are now established technique for easily changing your home to be able to run on direct current. Because the Vidje couple are planning on getting an electric car it made them curious about what options there were to be able to charge it at home. The most critical question was if a charging box is a requirement or not. The answer is pretty simple, a charging box is technically not a requirement, but using a 230 V power outlet as standard is a very bad and sometimes even considered as dangerous. It is also a very inefficient method because regular outlets can only put out a relatively low power charge and therefore would mean unreasonably long charging times. An 11 kW charger box seems to be the best option right now be able to charge your electric car at home. Quick chargers above 22 kW to exist but are usually expensive and only lowers the charging time a little bit which for most households are quite unnecessary.

Full textA school where the principle of recycling influence construction, systems and pedagogy. In consideration to the area and Annedal park's importance to the residents, the building has been incorporated as a thoughtful addition. Parts of the school's facilities, roof terrace and Cultural Center, is available to the public and therefore acts as a connecting link between the area's residents. Private courtyards, roof terrace and the contact with the public park offer a great variety of schoolchildren without limiting the park's area. The design of the school premises creates a safe and healthy environment for school children both spatially and materially. The untreated soft wood surfaces are worn by the children’s presence and give children the opportunity to put his mark on history. The school's surfaces can be replaced; plank for plank, the children will be given a freedom to wear on the surfaces. Prohibition and restriction should be replaced by a responsible right for children to leave traces. The corridors have been replaced by a winding, effluent, interconnecting room that can be used for different purposes; leisure, privacy, study room, dining room, transfers.

Full textBurkina Faso är ett av de fattigaste länderna i världen. Som ett kustlöst land beläget i Västafrika har det ett extremt varmt klimat. Temperaturer över 45°C är inte ovanligt och det är ett nästan konstant behov av att kyla byggnader för att behålla ett behagligt inneklimat. Idag byggs det två typer av byggnader i Burkina Faso; de traditionella lerhusen och de mer moderna husen med väggar av cementstenar och plåttak. Cementväggarna har ett U-värde på 3W/m2K och tillsammans med plåttaket så bildar det ett undermåligt klimatskal utan möjligheter att skydda mot hettan. Det leder idag till endera ett obehagligt varmt inneklimat eller en hög och kostsam energianvändning av luftkonditionering. Överbelastningen på elnätet på grund av luftkonditionering är påtaglig under den varmaste säsongen med frekventa strömavbrott till följd. Denna rapport undersöker via laboratorieexperiment vilka termiska och mekaniska egenskaper man kan erhålla genom att vibrera lerjord och blanda med vatten, organiska fibrer samt kalk och/eller cement. Litteraturstudier och fältbesök i Burkina Faso har gjorts för att undersöka och förstå vilka svårigheter som kan uppkomma genom att bygga med lera. Rapporten tar även upp konkreta exempel på byggnader i Burkina Faso gjorda av lokala material, historiska såväl som moderna projekt. Lerjord behöver extremt lite energitillförsel för att bilda ett byggmaterial och den negativa miljöpåverkan är försumbar jämfört med betong och stål. Det kan användas för att bygga energisnåla hus men det är känsligt mot vatten, vilket måste beaktas noga under projekteringen. Värmeledningsförmågan är för hög för att vara tillräcklig som isolering för att erhålla ett inneklimat enligt dagens standard, utan tillförsel av energi, så någon form av extra isolering krävs. Experimenten som gjordes gav inte tillräckligt exakta resultat för att visa om vibrering är en bra metod att göra byggmaterial eller inte. Den höga vattenhalten som krävs för vibrering är ett stort problem. Krympningen var ungefär 20 % och sprickor var svåra att undvika. Vidare studier på området rekommenderas.

Full textIn this thesis I examine how issues regarding sustainable energy use are handled in the development of two city districts in two of Sweden’s largest cities: Hammarby Sjöstad in Stockholm and Västra Hamnen in Malmö. The political goal was to build apartments with renewable energy supply and restricted energy use. The planning processes are analyzed from plans and visions to the evaluation phase. Both areas were meant to be outstanding examples of ecological housing development. The documentation pertaining to the objectives in both projects states that, firstly, new technology will contribute to the realisation of the goals, and, secondly, that the residents’ way of living will be decisive for whether the energy objectives are reached or not. The planning of Hammarby Sjöstad village was executed by the public administration of Stockholm City, and the planning of Västra Hamnen was carried out in cooperation with the Bo01-organisation. Deregulations took place in many areas in Sweden in the 1990s, for example subsidies for housing development decreased and the market for electricity was deregulated. This led to the involvement of privately owned buildingproprietors and energy companies in the projects. These actors partly had other interests than the politicians in that the private companies wanted to use time tested technology with new technology mainly as a “showcase”. The planning in Stockholm was characterized by objective oriented steering while the project in Malmö was characterized by consultations with the goal of reaching consensus in questions concerning the goals and design of the project’s energy solutions. In both these areas the solutions for energy supply became large-scale. This thesis shows that the organization of the planning- and building processes and the extra subsidies from the government to environmentally friendly solutions affected the results. One conclusion is that when the building proprietors were not invited to partake in the planning process and was dissatisfied, for example with the goal for reduced energy use (Hammarby Sjöstad), they formed a hindering coalition and took over power in the process. Irrespective of if the energy goals were decided in consensus or not, the lifecycle perspective was not given priority from the building proprietors’ side, for example, large windows were chosen while installations for individual metering were, in general, not chosen and the apartments were well equipped with prosperous consumers in focus. Here the interests of the building proprietors and the interests of the municipalities partly coincided, as the buildings proprietors wanted to build for prosperous groups and the municipalities, in one way, saw that these households could increase the taxes for the municipality. One conclusion is that criteria-driven governing, for example trough competition, can stimulate building proprietors to contribute with an extra effort and test new technology in separate houses. No residents took part in the planning of either district. In both city districts some residents have problems with deficient warmth and comfort which they attribute to an excessively short time for construction, negligence and sometimes lack of competence. Follow-up of the projects is connected to the subsidies given to the projects from the government and the EU-level.

Full textThis thesis explores building processes in the south of Sweden with the aim to accomplish low energy housing in accordance with the German standard for passive houses. In this thesis, the passive house is regarded as an innovative en-ergy concept which has been introduced to Sweden and to a conservative sector. The purpose of the study is to provide an understanding of processes in the im-plementation of an innovation for energy-saving dwellings. The process is recon-structed with data from interviews, minutes, articles, reports, etc, and presented as stories of different sequences including how the housing projects were organised, how the energy concept was established among the participants, how decisions were made and what messages were presented about the energy concept in mass media. The energy concept is followed in a process of transformation where it was subject to five fundamental acitivites: decomposition, moulding, composition, transportation and storage. The concepts originate from a time-geography per-spective, founded and developed by the Swedish geographer Torsten Hägerstrand. The energy concept was decomposed at a specific local context and transported to another, where it was moulded and composed into a new energy concept. The new energy concept was stored in a new setting. By following the trajectories of peo-ple and technologies, conclusions about the energy concept can be drawn. The building proprietors chose less conventional ways of managing the building proc-ess in order to have more control. The projects were started by people who them-selves had their own experience of passive houses. Solar collectors were loosely coupled to the energy concept and needed technology carriers.

Full textThe purpose of this thesis is to establish a functional program for an eco-cycle building where people can bereached with knowledge of sustainable development. The background to this is that the municipality ofBorlänge approved a plan program with the vision of creating a new, climate neutral district and therebybecome a precursor for sustainable construction in the region. For instance, the functional program is meantto investigate the background and the prerequisites that existed. In the municipality’s plan program, thebuilding is described to have an educational function for the district and for Borlänge; a place which focuseson practical demonstrations and education for students and residents in recycling issues for energy, waterand waste/material in a comprehensible and compelling way. The eco-cycle building is planned to beestablished near the new school, with classes from 6 to 9, to make a cooperation possible.Requests from the municipality is that the eco-cycle building can work like a hub in the new district, butalso become a new place of interest and put Borlänge on the map for sustainable construction. Sustainableconstruction includes resource management, minimized energy use and renewable energy sources, but alsothat resources like energy, waste and water circulate in an eco-cycle. Theory has been obtained fromliterature focusing on how we should build our houses and cities if we want to join and create a sustainablesociety.Part of the purpose of this thesis was to explore how to disseminate information on environmental andcircular issues in an educational way. The theoretical part of the thesis is therefore focusing on selected partsof education obtained from previous research in children and youth learning for sustainable development,since studies show that it is important that children learn about these issues early in life. Education forSustainable Development is an important prerequisite for achieving the sustainability goals set by the UNuntil 2030. Upcoming generations must learn a sustainable way of life right from the start while the existingpopulation must drastically change their lifestyle.In order to gather empiricism, interviews were held with people who have been involved in the planningwork with the new district. It turned out that there were former driving spirits who introduced the idea of theeco-cycle building, but that it doesn’t currently are the major priority in the ongoing work with the newschool and housing.Engaging the users at an early stage provides better conditions for achieving a result that is effective andsatisfying for all parties. The theory of design dialogues has therefore been studied to demonstrate theimportance of a good dialogue to quickly identify needs and develop ideas in design work.The result of the thesis, the functional program, can be seen as a draft on conceptual level with features andexpressions that can be applied to a building of this kind, and an inspiration for continued work. In thefunctional program, our interpretations form how the eco-cycle building would meet the requests andfunctions that’s been requested in the plan program, in order to benefit as much as possible in themunicipality's future work with the building.Conclusions are that there are no precursors of the eco-cycle building as a concept. Despite a large numberof sources of inspiration from various aspects, no example was found that combines all the aspects we havethe ambition to develop for this building. The eco-cycle building as a concept could play an important rolefor how to handle sustainable issues in a district or in a whole city. However, further work is required toinvestigate how the building should be run and managed, as well as more extensive studies of whichtechnical solutions to apply. Further work is also required to optimize the building for the future location,and the size of the building that are appropriate. There is a great interest in the building from variousparticipants in Borlänge, but to implement the idea of the eco-cycle building, one or more people need toembrace the project with the commitment that previously existed in the organization.
