Miljöcertifierade byggnader Värde för investeraren

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO

The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.

Den ekologiskt hållbara staden : en diskursanalytisk studie av styrningspraktiker i Hammarby Sjöstad

This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

Underlag till klimatledningssystem för skolor

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Vilken effekt har lärkrutor på ogräsfloran vid ekologisk höstveteodling? :

This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping. Studies in England have shown that skylark reproduction can be greatly improved within conventional fields, at a low cost, by establishing patches of bare ground (skylark plots). Within conventional farming, herbicides can be used in case a weed problem arises due to implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers. The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.

Demand and perception of fertilizer : among small-holder farmers in Kenya

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Environmental work in preschools : three case studies in Uppsala

Environmental issues are global problems and they are a major challenge for any successful organizational business worldwide. Many challenges and opportunities emerge during the certification process of an EMS. Therefore it is interesting to contribute in understanding these emerging problems during this process.The aim of this study is to explore how the environmental objectives could be achieved at preschools in Uppsala, investigate the perceived challenges and opportunities and to identify the outcome of implementing the ISO 14001, Green Flag at such set up.A qualitative method is used and three Green Flag certified preschools, affiliated to the Uppsala Municipality and located at different geographical location were selected. A structured interview with the environmental representatives from the preschools and the municipality was completed. The so-called PDCA-cycle as a method of evaluating sustainable development and analysing the imperial data is used.The study showed that environmental certification constitutes a great challenge for the municipality of Uppsala.

Rederiers hantering av nya miljökrav : En studie om Birka Cruises, Tallink Silja och Viking Lines arbete med ekonomisk och miljömässig hållbar utveckling

The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.

From industrial past to sustainable future : Arboretum Lövholmen; generating trees for a greener future

Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society. We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen. Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress? The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.

Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Hållbara livsstilar i svensk samhällsplanering : En underso?kning av forskning och ha?llbarhetsprogram

Problemen med fuktskador i byggnader är många och kostnaderna för att åtgärda problemen är stora. ByggaF är en metod som riktar sig till hela byggprocessen och den dokumenterar, kommunicerar samt säkerställer fuktsäkerheten genom hela den processen. NCC använder sig idag av en egen metod för att säkerställa fuktsäkerheten och den metoden jämförs i detta arbete mot ByggaF. Arbetet inriktar sig mot produktionsskedet av byggprocessen vilket innebär att fuktsäkerhetsarbetet är granskat i det skedet.Syftet med detta examensarbete är att NCC i Umeå ska få en bättre kännedom om vad ByggaF är och hur den metoden kan användas inom byggproduktion. Ytterligare syfte är att visa hur arbetet kan ske för att förebygga fuktskaderisken genom att använda metoden ByggaF, en metod för fuktsäkert byggande.Arbetet är utfört på NCCs byggnation på Öbacka strand etapp 4 och det bygget har fungerat som referens för NCCs fuktarbete.

Private-Public Partnerships (PPP) : collaborating for a sustainable business in Sweden

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

Bosättning, agrarkris och fäbodväsende : vegetations- och markanvändningshistoria i Läde, Dalarna

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.
