En solklar taklösning: En fallstudie på synergieffekter av bifacialsolceller och extensiva gröna tak / A sunny green roof solution: A study of the synergy effects of bifacial solar cells and extensive green roofs

Knudsen, Clara January 2020 (has links)
The master thesis has evaluated the specific combination of bifacial solar cells and extensive green roofs. This was done in terms of energy production per year, profitability as well as discussions around ecosystem services. Three cases have been simulated with different temperature profiles for both bifacial, vertical bifacial and monofacial. The reason for three cases was due to the uncertainty in temperature decreasing properties of vegetation i Sweden. One case was simulated for a normal black bitumen roof for the three types of solar PV. The result with the best energy production was found in the configuration with azimuth -10o, inclination 40o and height above roof at 40 cm. This was the case with the largest simulated temperature decrease. Albedo was set to 0.2 and this resulted in a bifacial gain of 9-10% for the three cases with green roofs installed. Albedo was found to be a larger factor in the energy production outcome than the temperature decrease from the vegetation. The solar cells contributes to shading the green roof partially which increases the local biodiversity as well as expands the lifetime of the vegetation. The combination was deemed profitable since the middle case had an annuity of 1841 SEK/year, but the case with the bitumen roof was found to be even more profitable with an annuity of 4160 SEK/year. This indicates that the extra cost of installing a green roof does not pay itself back with a higher energy production. / Det här examensarbetet har undersökt kombinationen bifacialsolceller med extensivt grönt tak med avseende på optimal utformning av en sådan anläggning på ett tak samt systemproduktion och lönsamhet hos anläggningen. Då det inte finns något klart modelleringsverktyg för hur stor temperatursänkning det gröna taket kan åstadkomma så har tre olika fall med olika temperaturprofil simulerats. Resultaten visade på att ju högre temperatursänkning det gröna taket kan bidra med desto lägre höjd bör bifacialsolcellerna installeras på. Den bästa systemproduktionen fås vid vinkeln 40o samt azimuth -10o för alla tre fall. Detta gav för medelfallet en bifacial gain på 9,6% vid jämförelse mot vanliga enkelsidiga solceller. Resultatet för vertikalt installerade bifacialsolceller gav minst 12% lägre systemproduktion än de med vinkel 40o men med hög osäkerhet kring tillförlitligheten i resultatet. Vertikal bifacial kan vara intressant då det ligger ett värde i att producera elektricitet efter ett normalt hushålls elkonsumtionskurva, men är mindre intressant för kontorsbyggnader där elkonsumtionen är relativt konstant under dagen. Lönsamhetskalkylen visade att kombinationen bifacialsolceller med grönt tak var lönsam, men inte lika lönsam som att installera på svart tak. För medelfallet gav bifacialsolceller på grönt tak en annuitet på 1841 kr/år medan annuiteten för bifacialsolceller på svart tak var hela 4160 kr/år. Ur ett rent ekonomiskt perspektiv är kombinationen alltså inte den mest lönsamma. Från känslighetsanalyserna konstaterades att albedo är den aspekt som har störst påverkan på systemproduktionen och denna är relativt låg för det gröna taket. Ett högre albedo hade därför varit att föredra till bifacialsolceller, vilket kan erhållas genom att exempelvis varva grönt tak med vita stenar. Vidare är kombinationen en platseffektiv lösning för tak som oftast är en outnyttjad ytresurs, där de olika installationerna bidrar med olika positiva nyttor var för sig. Bifacialsolcellerna bidrar till en ökad självförsörjningsgrad samt hjälper till att driva på den tekniska innovationen framåt. Gröna tak bidrar med många ekosystemtjänster såsom bullerreducering, dagvattenfördröjning, rening av luftpartiklar, lokal temperatursänkning. Kombinationen bidrar till en ökad biologisk mångfald och en lägre växtperiod för det gröna taket mot om den hade varit fristående.

Green Housing / Grönt bostadshus

Johnson Eriksson, Christian January 2014 (has links)
The Building is a combination of a green house and multi familyhousing building. The building´s courtyard is transformed in to a winter garden and creates an climate controlled environment with exotic vegitation blooming all year around. The courtyard is working as an extra livingroom with nice public walks in different levels were people can relax, exercise and socialise. The heat generated from the winter garden can be reused and recycled in to the floor slabs. It can also be deposited into the ground under the garden creating a climate smart heating system. One important aspect when drawing the plans was to give all the apartments a private space inside the wintergarden. I created plans where the allocation of the garden is equal. the private space is located on the second floor in the duplex apartments but some apartments only consist of one level and some extra care went in to making a private space for them too. The winter garden not only allows people to watch the trees and plants it also gives them the possibility to grow there own food on the private balcony and  just outside the kitchen window. Having plants outside the kitchen blocks the view from people passing by on the public promenade. / Byggnaden är en kombination av ett växthus och ett flerbostadshus. Byggnadens innergår har ett glastak som som möjliggör ett controllerat climat med växter som blommar året runt. innergården fungerar som ett extra vardagsrum med trevliga promenader i olika nivåer där människor kan träna, socialisera eller bara slapna av och njuta naturen. Värmen som genereras av den inglasade gården kan återanvändas och pupmas in i bjälklagen och marken under gården vilket skapar ett klimatsmart uppvärmningssystem.  en viktig aspekt när jag ritade planerna var att ge alla lägenheter ett privat rum inne i gården. Jag skapade planer där anspråket av gården var så lika som möjligt. Det privata rummet är placerat på övervåningen i etage lägenheterna men några lägenheter har bara ett plan vilket ledde till några special lösningar för att skapa ett avgränsat rum för dem också. Den ingalsade gården erbjuder inte bara en vacker miljö med växter och träd, det finns även möjlighet att odla sia egna frukter och grönsaker på den privata balkongen samt utanför köksfönstret. Planteringen av högre växter utanför fönstret kan skydda insynen från grannar som går förbi på den publika prommenaden.

Des Technosols construits à partir de produits résiduaires urbains : services écosystémiques fournis et évolution / Productive Technosol made of urban waste : delivered ecosystem services and evolution

Grard, Baptiste 21 December 2017 (has links)
Les villes ne cessent de se densifier au détriment des espaces de nature qui corrélativement se réduisent, tout comme les services écosystémiques qui leur sont associés. Face à ce constat, la végétalisation du bâti apparaît comme une alternative indispensable. Dans ce cadre, les toitures végétalisées font partie des outils d'aménagement des villes qui sont en pleine expansion. Ces toitures revêtent différentes formes, s'adaptant aux contraintes et enjeux urbains. Depuis quelques années, une nouvelle forme de toiture végétalisée a émergé : les toitures végétalisées productives (e.g. de biomasse alimentaire). Encore peu développée et mal connue, l'intérêt concernant cette forme de toiture ne cesse de croître. Leur conception, leur aménagement et surtout les services écosystémiques quelles peuvent rendre sont aujourd’hui encore mal connus et nécessitent d’être mieux appréhendés. Clé de voûte des toitures végétalisées, le sol en place influence directement et indirectement les services écosystémiques rendus par celles-ci. En dépit du rôle majeur de ces sols, peu d'études leur sont consacrés. Par ailleurs, des produits non renouvelables tels que la pouzzolane, l’argile expansée ou la tourbe sont aujourd’hui très majoritairement utilisés dans leur composition. Nous avons étudié des Technosols, c’est à dire des sols reconstitués, de toitures productives composés uniquement de produits issus de résidus du milieu urbain. Ce travail a eu une double ambition : (i) évaluer quantitativement les services écosystémiques rendus et (ii) comprendre les premières phases d’évolution des Technosols. Pour cela, trois dispositifs expérimentaux, installés sur la toiture « Bertrand Ney » de l’école AgroParisTech ont été utilisés. Il s’agit de bacs de cultures dans lesquels des sols sont construits, avec des agencements divers de cinq résidus urbains: un compost de déchet vert, du bois broyé, de la brique et de la tuile concassée, un résidu de champignonnière et un compost de biodéchet. Nous avons étudié l’effet des différents types de Technosols construits sur (i) les services écosystémiques rendus, (ii) la production alimentaire (quantitative et qualitative), (iii) la fertilité physico-chimique et (iv) leur évolution temporelle. Les Technosols construits sont fertiles et permettent une production alimentaire conséquente sur une à cinq années, caractérisée par de faibles teneurs en éléments traces métalliques équivalentes à celles de la moyenne des productions maraichères. L’évaluation quantitative de services écosystémiques (production alimentaire, recyclage de résidus urbain, rétention des eaux de pluies et qualité des eaux de percolations (C et N), a souligné le caractère multifonctionnel des systèmes étudiés et met en évidence un disservice, qui est une altération de la qualité des eaux de percolation par lixiviation du carbone, pouvant être liée à celle d’autres éléments. Une première phase de pédogénèse rapide et intense est observée, marquée par une forte biodégradation des matériaux et une forte lixiviation. Nos travaux ont mis en évidence l’existence d’un double compromis dans la conception d’un Technosol productif, entre (1) la biodégradation des matériaux (assurant la fourniture des nutriments minéraux aux plantes) et le maintien de la structure et porosité du matériau, donc de sa fertilité physique d’une part et entre (2) la fourniture d’élément nutritifs par biodégradation et la lixiviation, se traduisant par une perte de ces éléments et une altération de la qualité des eaux de percolation d’autre part. La connaissance des propriétés des matériaux utilisés et de ses liens avec les services écosystémiques attendus permet déjà de concevoir des toitures productives multifonctionnelles à partir de résidus urbains et de les gérer de manière durable. / Cities are becoming denser at the expense of nature spaces that are correspondingly decreasing, as are the ecosystem services associated with them. Faced with this observation, the greening of buildings appears as a valuable alternative. Nowadays, green roofs have become a planning tool in urban planning. These roofs take different forms, adapting to urban constraints and challenges. In recent years, a new form of green roof has emerged: productive green roofs (i.e. of edible biomass). Despite a growing interest, rooftop farming is still poorly developed and known. Their design, their development and especially, the ecosystem services they could deliver are still poorly understood and need to be known. Keystone to green roofs, the soil in place directly and indirectly influences the provided ecosystem services. Despite, it’s key role, soil is still poorly studied. Furthermore, non-renewable products such as pozzolan or expanded clay or peat are today mostly used in their composition. In this work we have studied constructed soils, named Technosols, for productive roofs made only of urban wastes. The objectives of this thesis were: (i) to achieve a quantitative assessment of delivered ecosystem services (ii) analyze the first stages of Technosol pedogenesis. In order to do so, three experimental devices were implemented on the “Bertrand Ney” rooftop of the technical University AgroParisTech in Paris. The experimental devices consist of multiple plots filled with different disposal of five urban wastes: green waste compost, shredded woods, crushed tiles and bricks, spent coffee grounds used to grow mushroom and a biowaste compost. The impact of the different Technosols on (i) ecosystem services, (ii) food production (quality and quantity), (iii) fertility) and (iv) temporal evolution, were assessed. Constructed Technosol are fertile and allow a consistent food production over one to five years. The level of food production was equivalent to that of a professional producer and food quality regarding trace metal element was below existing norms. The quantitative assessment of ecosystem services (food production, urban waste recycling, rainwater retention and overflow quality (C and N)), highlighted the multifunctional nature of productive green roofs. However, we identified an ecosystem disservice which is an alteration in the quality of the leachates due to carbon leaching and presumably other elements. A first phase of rapid and strong pedogenesis was observed marked by an intense biodegradation and lixiviation of the Technosols. Our works identified two trade-offs in the design of a productive Technosol: between (i) the biodegradation or organic materials (ensuring the supply of mineral nutrient to plants) and the maintenance of the structure and porosity of the Technosol (i.e. its physical fertility) and (ii) the supply of nutrients by biodegradation and leaching, resulting in a loss of these elements and an alteration of the quality of percolation waters on the other hand. Knowledge of the properties of the materials used to build Technosols and on their link with the expected ecosystem services already makes it possible to design multifunctional productive rooftop based on urban waste and manage them sustainably.

Nová Jižní čtvrť a její propojení s řekou Svratkou / New South District and its Connection to Svratka

Leitmannová, Barbora January 2019 (has links)
The Master‘s thesis deals with the processing of the architectural study of the city block in the planned new South Quarter near the Svratka River. The project builds on a pre-diploma project whose aim was to create a territorial urban study for part of this neighbourhood. It was a section between the New Railway Station, Opuštěná Street and the existing Zvonařka Bus Station following the river embankment. The subject of the master‘s thesis is a block from this newly designed urban structure, situated in very close proximity to the river. he project focuses on the block as a whole. It conceptually solves the links between newly designed buildings, individual operations, and functions. It deals with the relationship between streets, river and buildings. Great attention is paid to the maximum use of greenery in the form of extensive and intensive roofs, internal blocks, private gardens in the inner block, as well as private front gardens. The concept seeks to provide a wide range of options and differences. This creates a closed city block that is open and responding to the river with its shape, that consists of free parts. The first / majority are the street lining. It is mostly 5-storey. Corner buildings are raised by one floor, allowing roof intensive gardens to be created. It includes a diverse range of residential units overlooking the river. Housing prevails here. On the ground floor there are a few commercial units and work-and-live. The work-and-live area also includes a private front yard on the street and private raised gardens in the interior. The second part consists of two objects extended over the pedestrian shopping promenade. One of the objects was subject of my detailed architectural study. There are the most luxurious apartments, ground floor showroom and concept store. The third part consists of a lowered 2-storey embankment building, which by its height provides the rest of the block with a beautiful, unimpeded view of the river. It covers the

Medová, Jana Unknown Date (has links)
The main aim of the thesis is to design a Kindergarten. It is situated on the west outskirt of the Havlíčkův Brod on the plot no. 653/1 in the cadastral area Havlíčkův Brod. The plot is sloped to the south. The building has two above-ground floors. The ground floor is cross shaped, and we can consist of it on four parts. Three are classrooms with locker room, sanitary facilities for children and bed storeroom. The last part is technical facilities (storerooms, halls, utility room, control room and room for serving food). On the first floor there are offices for teachers, staff room, director’s room, and locker room for employees (cooks, cleaners). Food will be imported to kindergarten. My project is designed like a masonry wall system from sand-lime blocks Silka. Non-load bearing walls are from aerated concrete blocks Ytong. Floor structures are designed as pre-stressed concrete panels. Roof above the ground floor is flat intensive green roof and roof above the first ground floor is flat extensive green roof. The building is heated by two gas boilers in the utility room and and the whole is forcibly ventilated according to two air-conditioning units. I use Archicad 22 for designing my Kindergarten.
