This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Vad är ett ?Urban building??Den första tanken som slog mig var en byggnad liknande ett komplex, med en mängd olika funktioner.Därför blev det ett självklart val för mig var byggnadens footprint skulle vara, när jag såg den "övergivna" landsplätten. Jag skulle vilja kalla den för en tom lucka kanske. Vidare tänkte jag vad detta komplex av byggnad skulle vara. För mig var det viktigt att skapa en mötesplats för människor, men med det sagt, inte ett kommersiellt centrum.

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

The homes that were built in the 60?s - and 70's are now so dilapidated and worn that they need thorough renovations. These renovations are expensive to implement for the landlords, which means that the funding for these renovations can create problems. Currently there are no government subsidies for these renovations. This report will examine how Förbo performed the renovation of Säteriet.

Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.

This project explores how artificial landscapes as parks and squares above ground can save space by using the vertical voids in urban environments and how they can create spatial and social as well as ecological qualities and connections. Hybrid landscapes are a phenomenon of current interest within the field of architecture and urbanism. Architecture as surface, where facades and roofs become possible to tread, is a relatively recent occurence that has over the past few years become an increasingly common sight in architectural magazines and on international architecture exhibitions. Many of my selected reference projects have often been associated with sensational contemporary design trends generated by advanced computer software. But the phenomenon is also a result of other different currents of change that exist within today?s society, such as densified cities with a lack of open space, which is also expressed in architecture.

Denna uppsats syftar till att presentera erfarenheter av grönsaksodling på tak samt utreda klimatförhållanden och odlingsförutsättningar på Augustenborgs Botaniska Takträdgård i Malmö. Uppsatsen avslutas med förslag på förbättringar och åtgärder för grönsaksodlingen på taket i Augustenborg. Arbetetet omfattar således en generell och en platsspecifik del. Uppsatsen har tillkommit genom litteraturstudier, intervjuer och studier på plats i Augustenborgs takträdgård. Takodling av grönsaker anknyter till såväl gröna tak som stadsodling och dess popularitet ökar i världen. I Sverige förekommer gröna Sedum-tak alltmer och stadsodling har förankrats i våra storstäder. Tak är outnyttjade platser med god potential för odling.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.
