The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.

Sustainability is a term that is constantly gaining focus in our society and we are becoming more and more aware of the need to take the next generation into consideration when making decisions. The sustainable activity within the core business is growing and is also connected to profitability in ways that have not been seen before. However, the activities that are not included in the core business have not yet reached this long-term perspective. These non-core businesses within an organization goes under the term Facilities Management (FM).This paper focuses onReal Estate businesses, FM-suppliers and the relation between them.The purpose is to investigate current knowledge regarding outsourced FM-services and the real estate organisation?s use of these services.

Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

Today we see a growing need and interest in working towards sustainable development. To be able to contribute to a sustainable development as individuals/business we need to emphasize the importance of education and contextualisation that learning occurs in a sense that is relevant to the learner.This is the background to this study, which in turn is the basis for an education that focuses on how to environmentally secure your purchases, an opportunity for us to set environmental standards purchasing products and services. The process for purchase is considered by many to be a key factor in businesses work towards sustainable development. Key people in this process and target audience for this education is environmental, purchasing and procurement managers.The purpose of this study is to design an education calledMiljösäkrade inköp from the target audiences? knowledge, interests and attitudes, together with literature.

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

This master thesis is about sustainable city planning and its debate. It is also concerned with networking, communication and web-based communication. Theories of sustainable development are discussed, along with the importance of communication for sustainable development. The report is directed towards landscape architects, architects, town planners, other designers and other interested readers.MotivationI believe that there is a need for an increased discussion concerning sustainability. Sustainable development is an important issue for city planners.

Byggbranschen har flertalet gånger blivit kritiserad för att inte uppnå samma utveckling och produktivitet som andra sektorer. Visionen om ett effektivt samhällsbyggande är ändå positiv och en av de stora nämnarna för framgång är BIM, Building Information Modeling. Arbetsmetoden, som handlar om att effektivt tillhandahålla information, tillämpas redan i relativt stor utsträckning på hussidan. Samtidigt ligger bro- och anläggningssidan i startgroparna för att följa efter husbyggnad i utvecklingen.NCC Montagebro är en prefabricerad betongbro som utvecklades på 80-talet och som återigen lyfts fram för utveckling. De tidigare standardmåtten har avskaffats för att i högre grad möta kundens önskemål om längd och bredd.

The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

Det är allt vanligare inom tredjepartslogistik att kunder hyr en yta för lagring. För den uthyrande parten, i detta fall Delta Terminal, är arean den begränsande faktorn för hur stor yta som kan hyras ut. Idag använ-der sig Delta Terminal av beslutsunderlag i form av lokalernas area och erfarenhet vart gods ska placeras och har inget hjälpmedel för att beräkna vart och hur mycket gods som kan allokeras för att använda så liten yta som möjligt. Studiens syfte har därför varit att ta fram ett faktabaserat hjälpmedel som kan användas som beslutsunderlag. För att uppnå syftet har en matematisk modell utvecklats för att optimera hur gods kan placeras till olika lokaler för att använda så liten area som möjligt och även kunna simulera förändringar.

Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.
