    FLEXIBLA BYGGNADER: Utformning av en förskola med en möjlig verksamhetsändring för framtida behov2014Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    För att uppnå ett långsiktigt hållbart samhälle ställs idag höga krav på en miljömässigt och ekonomiskt hållbar utveckling. Samhällets expansion i form av nybyggnation är en stor del i detta. Genom att planera och bygga mer långsiktigt hållbara byggnader så kan dessa krav uppfyllas. Att skapa flexibla byggnader, som kan anpassas efter samhällets framtida behov, leder till en effektivisering av lokalutnyttjandet och genererar mer långsiktigt hållbara byggnader. I Sverige är kommunerna landets största byggherrar och de har därför ett stort ansvar att förse samhället med fastigheter och då framförallt offentliga lokaler. En typ av offentliga lokaler där behovet av flexibla byggnader är stort är förskolor, i och med att det är svårt att förutse hur det framtida behovet av förskolor kommer att se ut då storleken på barnkullarna varierar.

    Detta examensarbete inom högskoleingenjörsprogrammet i byggteknik har utförts under tio veckor på Tengbom Arkitekter i Uppsala. Arbetet behandlar ämnet flexibilitet i byggnader och innefattar ett förslag på utformningen av en flexibel byggnad i form av en förskola som i framtiden kan konverteras till ett äldreboende.

    User-driven energy efficiency in historic buildings: A review2017Inngår i: Journal of Cultural Heritage, ISSN 1296-2074, E-ISSN 1778-3674, Vol. 28, s. 188-195Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    The paper draws from the general literature on energy efficiency and historic buildings to explain the importance and potential of user-driven energy efficiency in historic buildings. It is the first review that places the user as a central object of study in the research field of historic buildings and energy efficiency. Relevant interdisciplinary topics and research results that make up the core of the field are presented and discussed in relation to user behaviour and its impact on energy consumption. The paper also investigates how user behaviour aspects can be integrated in a procedural approach to energy refurbishment in historic buildings. Research and experience from the building stock in general clearly shows how a user's awareness and behaviour, such as choice of temperature, zone heating and controlled airing, can have a significant effect on energy demand yet have no physical impact on the building. However, this has not received enough attention with regards to the historic building stock, where many physical energy efficiency measures can have negative impacts on the historic qualities of the building. Modification of user behaviour can therefore be a way not only to reduce energy demand but also to minimise the physical impact of increasing energy efficiency on historic buildings. The paper concludes that the current research agenda on historic buildings and energy efficiency has broken much ground but remains focused more on technical solutions than bottom-up user perspectives. Two main topics are identified as key barriers and future research fields: First, energy performance modelling is identified as a general barrier to developing sustainable strategies that promote user impact in historic buildings. Accurate energy modelling of historic buildings is a complex field reliant on the thermal interplay between user-building and building-district. Improved knowledge and intensified research is necessary to avoid distorted energy modelling results and unwanted rebound effects. Practical tools also require that the modelling can be used for trade-off scenarios where other sustainability aspects such as cultural heritage and economy are weighed in. Second, awareness raising in order to foster a deeper understanding and knowledge about the construction, system and cultural heritage values of a building is proposed as a key ingredient and driver for improved and sustainable energy behaviour. The paper argues that while user-driven energy efficiency represents an important resource for fostering less energy-demanding and less intrusive interventions in historic buildings, there are no guarantees for achieving the planned level of energy efficiency without taking into account user behaviour and the actual operation and energy performance of the historic building. To do this without risking negative consequences, improved decision-making processes are needed on policy, building and user level. An interdisciplinary bottom-up approach to energy refurbishment is presented. The essence of the model is that users and residents should always play a central role in the decision-making process because the well-being of the historic building will always depend on its day-to-day users, and vice versa.

    Barnservis2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Innovatören Håkan Berndtsson har utvecklat en idé till ett nytt grepp på bestick för små barn som ska börja lära sig äta själva. Idén undersöks i detta examensprojekt för att skapa ett helhetskoncept på en servis för barn. Fokus ligger på utveckling av Berndtssons bestick där kniv, gaffel och sked ingår. Detta genom att tillämpa designmetodik.

    Problemet med många barnbestick som finns ute idag är att barnen har svårt att få till ett grepp som gör att dem på ett enkelt sätt kan föra maten till munnen. Resultatet av detta blir mycket spill och kladd vid måltiden. Barnen tröttnar vid stora svårigheter med måltidsredskapen och de får i sig mindre mat. 

    Målgruppen för projektet var barn som ska börja lära sig äta själva med olika måltidsredskap. Detta sker i ett spann av ca ett till tre år beroende på barnets individuella utveckling.

    Lösningen på problemet består i ett grepp som kombinerar ett kraft- och precisionsgrepp för gaffeln och skeden. Barnet kan då utan vidare ansträngning föra in maten i munnen med precision. Kniven har en annan funktion och har därför utformats efter detta, nämligen att skära och trycka sönder maten. Övergripande förslag på lösningar på mugg, tallrik och skål har gjorts. Muggens koncept består i att den kan utvecklas med barnet genom att ha olika delar som anpassar dess funktion efter barnets ålder. Tallrik och skål kan sättas ihop och bilda en matlåda med lock.

    Resultatet består av tre bestick, en gaffel, en sked och en kniv där samtliga grepp är utarbetade efter ergonomiska studier och nära samarbeten med barn på förskola. Utvecklingen av resterande delar i servisen stoppades efter revidering av projektet i slutet av idégenereringsfasen. Resultatets formspråk är ett genomgående djurtema som för samman måltidsredskapen under samma formspråk och till ett koncept. Temat djur är relativt könsneutralt och är pedagogiskt anpassat för de mindre barnen. Bestickens grepp består av plast med ät-delen i rostfritt stål.

    Lysande rör, rörligt ideal: belysningsbranschens introducerande av lysröret i Sverige2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g. cinemas and public baths) and the discharge lamp in the industry) none of them could provide a light that combined efficiency in both light and cost.

    This essay deals with the predecessors as well as the introduction of fluorescent lighting in Sweden 1940-1945 primarily as a consequence of todays non existing historic knowledge about this modernist invention. By analyzing articles and advertising issued by the Swedish journals Elektricitetens rationella användning and Tidskrift för Ljuskultur 1930-1945 this thesis answers questions about how, why, when and where the lamp industry came to bring the new kind of light on the market.

    The research concludes that fluorescent lighting was introduced in almost every environment except for the homes, even though the Swedish lighting associations believed it to be the future also for the homes. The prospects for the new light source were without exeption positive and promising and in both articles and advertising it was talked about as the ”artificial daylight”. The light fittings were made different depending on the purpose of the room. Esthetic as well as functional reasons together with the extracted shape of the lamp made the designers make fittings that differentiated heavily from the fluorescent light fittings we are used to see today.

    Framtagning av nyckeltal för bestämning av dagsljusprestandan hos solskyddssystem för fasader2019Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    In this paper a method for evaluating the performance of sunshades

    and the controlling of the sunshades is presented. The method

    evaluates the sunshades in the perspective of the availability of

    useful daylight over the year in the room where the sunshades are

    installed. The metric is based on a climate based daylight metric

    called “Useful daylight illuminance” (UDI), which shows the fraction

    of the occupied time that the illuminance in one point is within a

    predefined illuminance interval. Furthermore the relation between the

    presented metric and the consumption of energy was investigated.

    The method is a result from a literature study. The literature used

    in the study mainly consists of articles on the subject daylight in

    buildings and daylight metrics.

    Two different sunshade technics was evaluated with the presented

    method, an electrochromic window and an external textile screen. The

    simulations were made in Rhino 6 and the levels of daylight were

    calculated with daylight coefficients.

    According to the results the electrochromic window had a better

    performance in both the availability of useful daylight and in the

    consumption of energy for heating and cooling the room.

    Viktiga aspekter i samverkansformen NCC Projektstudio: En intervjustudie för NCC2013Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    The projecting time in the construction industry needs to become more efficient to

    shorten the amount of time it takes to project a build. One of the North's leading

    construction company NCC constuction Sweden AB has developed a form of

    collaboration called ”NCC project studio” that they use in some projects today.

    My thesis consists in bringing forth the most important aspects of the collaboration

    form called NCC project studio. The point of this is to use my thesis to help the

    company develop a quality document that can assist them when starting collaboration

    based on NCC project studio in the future.

    The conclusion of my thesis was that much of the focus needs to be on explaining to

    the participants what NCC is aiming to gain from working with the NCC project

    studio and also which important parts that needs to be worked on.

    Prioriterade studentbostäder: Ett projekteringsunderlag för kostnadseffektivare utformning utifrån studenters egna prioriteringar2017Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    This report examines what students prioritize and value in student housing. The content of the report can be used as a basis for designing new student housing to better match students' wishes, while the production of student housing can be made more cost effective. This report examines which functions of a home that students prioritize and value, and which functions students may consider sharing with others. Additionally, the report studies whether the designing of student housing needs to be differentiated to better suit different groups of students. The examination has been conducted primarily with an internet-based survey that 839 Swedish students responded to. There after an interview study was conducted with selected students representing different groups of students. The work has been carried out in cooperation with the Swedish real estate company Rikshem AB. An interview study was also conducted with other parties who are involved in and has influencing over the design of student housing. This was done in order for the proposals presented in the report to be useful to all involved, be feasible and contribute to a more cost-effective construction of student housing. As a background to the report lies the current housing shortage and the economical difficulty in getting new construction projects with student housing to be profitable. At the same time, there are dissatisfaction among many students over the student housing units that exist because of its lack of functionality and over high rents in new housing. The result of the study shows that students primarily prioritize the so-called “buddy-apartment” with two students sharing a common area, bathroom and kitchen. Secondly, students prioritize a student apartment where they alone have all the functions in the apartment. The result of the work also shows that students primarily prioritize larger social areas, having their own balconies and dishwashers in their homes. However, the former is not economically realistic to put into practice. Students do not prioritize having a washing machine in the apartment, larger workplace or additional storage. Finally, recommendations are submitted for the design of new student housing projects, and it is noted that the differences between different groups of students do not require new housing types than those otherwise mentioned in the report.

    Visbys färger: exteriör färgsättning av bostadshus i Visby innerstad 1860–19302013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860–1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs). The field study includes about 45 objects, in which a number ofsamples are taken from each building element (mouldings, plaster, windows and doors). Thesamples were first analysed ocularly as cross sections. A selection of cross sections have then beenanalysed by means of scanning electron microscopy analysis. The results show a unitary colourscheme, based on earth pigment and carbon black. The dwellings erected during the 19th centuryin Visby, represent a significant part of its building stock, and the lack of scientifically groundedresearches makes implementation of adequate maintenance difficult. It also appears that a largenumber of these dwellings have recently been (or are soon to be) restored, causing a serious lossof primary source of information, as well as affecting town and streetscape with new colourings.

    The historical indoor climate: A long-term approach to conservation environments within heritage buildings2013Inngår i: Online Proceedings of the Conference: Built Heritage 2013, Monitoring Conservation and Management; Milan, Italy / [ed] M. Boriani, R. Gabaglio and D. Gulotta, Milano: Politecnico di Milano , 2013, s. 1321-1328Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The aim of this paper is to demonstrate the usefulness of archival sources and architectural analysis in tracing the indoor climate history of an historic building such as an old museum, a church or a palace. References to past indoor climate have often been used either to defend status quo or to justify radical changes in the climate control of a building.

    The concept of historical climate can be used in many different contexts. In the field of conservation, it has recently been defined by the European standard EN15757:2010 as the “climatic conditions in a microenvironment where a cultural heritage object has always been kept, or has been kept for a long period of time (at least one year) and to which it has become acclimatized”. Unlike many previous environmental standards, the priority is here not so much in specifying hygrothermal ranges, but in measuring the existing climatic conditions and in understanding whether the environment to which a cultural object has been exposed for a long period of time is harmful or not. As a consequence the focus should be shifted to the climatic history of the object, intended as the complex set of interactions developed throughout an extended period of time between a cultural object, its environment and the surrounding architec- ture. The term “conservation environment” introduced in this paper proposes a development of the analysis by including outdoor and indoor climate and the microenvironments which can influence buildings and artworks.

    When a cultural object is preserved within a historic building, further questions arise: which climate control strategies determined the conditions of conservation environments in the past? On what grounds were these strategies chosen and subsequently used? Which were their consequences on the conservation of cultural objects and buildings? To answer these questions environmental data gathered by indoor climate monitoring are useful but they are obviously not enough. A critical analysis of historical sources has proved to be a constructive way forward.

    Abstract [sv]

    The indoor climate in a number of Scandinavian historic buildings such as churches, castles and manor houses deviates considerably from climate recommendations given for museums. Nonetheless, these buildings accommodate fragile and valuable movable and immovable objects. In the present article, a brief literature review of the risk of mechanical damages to art objects caused by fluctuations in temperature and relative humidity is given. Two cases are presented to illustrate the problems with indoor climates that deviates from common standards. The two cases were chosen because they are interesting from an energy saving perspective. The first case is an intermittently heated church in northern Sweden, typical for a Scandinavian rural church used only for services. The second case is a completely unheated building with an indoor climate closely following the fluctuations of the outdoor climate, including sub-zero temperatures in winter. The research about mechanical damages is discussed with reference to these cases. Two areas are identified where more research is needed. There is limited knowledge on the correlation between a fluctuating indoor climate and the risk of mechanical damages, i.e. the rate of temperature and relative humidity changes. Secondly, the knowledge of how low temperatures affect the risk of mechanical damages is inadequate.

    Energideklarationer och kulturvärden2006Independent thesis Basic level (degree of Bachelor), 15 poäng / 22,5 hpOppgave
    Abstract [en]

    The European Directive on the Energy Performance of Buildings 2002/91/EC will soon be implemented in Sweden. Legislation about energy certificates will probably take effect in Sweden during October 2006. In this thesis I try to investigate if and how cultural values in the building stock will be affected by the introduction of compulsory energy certificates for existing buildings. My aim is to find out how the procedures and methods involved in the process of acquiring the certificates can be adjusted in a way that will preserve the cultural values. The subject of energy saving and its impact on historic building is briefly presented in the first chapters. Relevant Swedish legislation is described. The new Swedish legislation about energy certificates is summarized, with focus on the parts that might be important considering historic buildings. Three case studies constitute the core of the investigation. Energy certificates are constructed for three different one-family houses. The method that is supposed to be used when constructing the energy certificates is not yet established in Sweden, but the basis is somewhat decided. The results from each energy certificate have then been discussed with preservation issues in mind. Especially the recommendations for cost-effective improvements of the energy performance that are presented in the certificates are discussed. Undoubtedly, there is a potential for energy saving in historic buildings. Most culturally valuable buildings were built with constructions which are inferior to modern when it comes to energy performance. In the case of one- and two-family houses measures that affect the building shell (i.e. retrofitting and exchange of windows) will be proven cost-effective and therefore suggested in the certificates. We know that these kinds of measures are prone to affect the cultural and aesthetic values of historic buildings. This is well known in Sweden since the 1970´s, when many careless energy saving measures were made in connection with the oil crisis. The main conclusion made is that the independent experts who are supposed to carry out the work to produce the energy certificates should have a basic understanding of the problems involved. This necessary qualification should be applied for all categories of buildings, not only monumental ones. In the case of monumental buildings, where the cultural values are more obvious, it is in fact easier to be aware of the risks involved.

    Kyrkobyggnader och klimatförändringar2015Rapport (Annet vitenskapelig)
    Abstract [sv]

    Syftet med rapporten är att identifiera och värdera framtida inneklimatre-laterade risker i kyrkobyggnader på grund av framtida klimatförändringar samt att undersöka hur informationen om framtida risker kan användas. Vidare diskuteras styrkor och svagheter med befintlig fastighetsförvaltning med avseende på klimatanpassning. Undersökningen bygger på resultat från det europeiska projektet Climate for Culture där framtida risker, förknippade med klimatförändringar, pre-senteras i form av riskkartor. Som komplement till detta genomfördes en intervjuundersökning med ett tjugotal personer inom Svenska kyrkan som arbetar med fastighetsförvaltning.Undersökningen visar att risker för mögel och insektsangrepp ökar sig-nifikant medan andra risker, t ex mekaniska skador på bemålat trä, inte ökar. Följdfrågan blir då, vilka åtgärder kan eller bör vidtas i nuläget? För-fattarnas uppfattning är att klimatförändringarna förstärker betydelsen av förebyggande åtgärder och regelbundna kontroller för att förhindra innekli-matrelaterade skador. Vid långsiktiga insatser och investeringar, till exem-pel vid nyinstallation av uppvärmnings- eller avfuktningsanläggningar, bör kommande klimatförändringar beaktas vid dimensioneringen. Vidare borde Svenska kyrkan, i samverkan med andra nationella aktörer, överväga att införa ett program för långsiktiga uppföljningar av effekter på inneklimat och skador i kyrkor.

    Strävan efter ett ordnat samhälle: Stadsplanering i Huddinge 1900-19602005Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Suburbs sprang up round about many Swedish towns and cities in and around 1900. For obvious reasons, they were most numerous round about the City of Stockholm. This thesis sets out to map and discuss urban planning in the suburban Stockholm municipalities between 1900 and 1960. Urban planning development in the suburban municipalities differs to a great extent from that of the towns, cities and boroughs of Sweden. The reason for the difference is to a great extent to be found in the structure of urban planning legislation.

    I have chosen to undertake two case studies, both in Huddinge. The first concerns urban planning in the rural townships of Huddinge at the beginning of the 20th century, and second the construction of rental housing undertaken by the municipality in central Huddinge during the late 1940s and the 1950s. Comparison with two reference municipalities, Täby and Sollentuna, shows Huddinge in many ways typifying developments in the suburban Stockholm municipalities, the main differences being that Huddinge had six rural townships – the largest number anywhere in Sweden – and in the late 1940s and the 1950s built multi-family housing under its own aegis.

    Indigenous Materials in Modern Buildings: for low energy houses in West Africa2014Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Burkina Faso is one of the poorest countries in the world. This landlocked country in the west has an extremely warm climate. Temperatures over 45°C are not uncommon and there is an almost constant need to keep the buildings cool to maintain a temperate indoor climate. Air-conditioning is an option to maintain the temperature but it overloads the power grid and only a few people can afford it. This thesis examines, through laboratory experiments, the thermal and mechanical properties that can be obtained by vibrating clayey soil and mixing it with water, lime or cement and organic fiber (Bissap). The report also examines different building projects utilizing local materials, both of a traditional and more modern nature.Energy required to produce building elements of soil is negligible compared to that of concrete and steel. Soil can be used in constructing houses but it is sensitive to water.The insulation is inadequate for a passive house so an extra layer of insulating material is required.The experiments performed during this project were inconclusive so it is impossible, from the results in this paper, to say if vibration is a good method for forming a building material of soil. The high water content needed, is however a major problem, shrinkage was about 20% and cracks were hard to avoid. Further investigations into the subject is necessary.

    6. Living in the 21st century: The ecological community of Braamwisch2003Inngår i: Urban Environmental Management: Reports from the Superbs project / [ed] Lars Rydén, Uppsala: Baltic University Press , 2003, 1, s. 67-72Kapittel i bok, del av antologi (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    Inhabitants in ecological communities develop integrated strategies for environmentally friendly lifestyles. The eco-community of Braamwisch in the northeastern part of Hamburg, Germany, has developed far-reaching ecological strategies in several ways. Braamwisch includes 40 houses built 1996-2000, all with low energy construction methods, and extremely good insulation. Much of the heating is made using local solar heating, while green electricity was bought from outside, and to an extent came from local photovoltaic cells. All building materials used were environmentally safe. Toilets were mostly dry composting toilets. Water consumption was considerably reduced without water toilets (about 20,000 liters per year and person), and further reduced by the use of rainwater. Wastewater consists only of grey water, which is treated locally in three reed beds. Kitchen waste is mostly composted in the same bid as toilet waste. The inhabitrants cause little environmental impact by traffic as they use car-sharing and in addition, the community is located close to the public transport of Hamburg and needed commodities, such as schools, shops and doctors office, are within walking distance. The social dimension of life in an eco-community is also important as described in this report.
