Hållbart agerande inomFacilities Management ? Fem förslag på förändrade arbetssätt vid outcourcing

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.

Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie

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.

En uppföljning av floran i Enköpings vattenpark : kan anlagda våtmarker med vattenrening som huvudsyfte bidra till naturvård och biologisk mångfald?

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.

Att utveckla en kurs i miljösäkrade inköp

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.

Avbördningsekvationer för sjöar utan vattenföringsmätningar

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.

Att kommunicera hållbarhet : en undersökning av hållbarhetsdebatten via internet

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.

Förändringar i vegetationens sammansättning efter en våtmarksrestaurering : Changes in the vegetation composition after a wetlandrestoration

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.

Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län

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.

Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

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.

Den interna styrningens påverkan på motivationen : En fallstudie över styrsystemet i en icke vinstdrivande nischbank

Bakgrund och problemdiskussion: Styrsystem är ett brett och komplext begrepp som kan innehålla många olika komponenter, till exempel budgetering. Bankverksamheterna är hårt reglerade utifrån de lagar och regler som gäller i det aktuella landet som de är verksamma inom. Därför är det viktigt att ha tydliga riktlinjer och styra de anställda så att de inte bryter mot några lagar och/eller regler. Dock finns det en viss problematik kring en hårt reglerad verksamhet. Till exempel kan både regler och strikta budgetar leda till att de anställdas motivation påverkas negativt då de är hårt hållna och inte kan arbeta på det sätt de vill på grund av strikta riktlinjer.

Gestaltning av stadens utemiljöer - Naturlikt kontra formellt & abstrakt :

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.

Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Ekoturismens natur- och miljöpåverkan i polarområden

Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.
