Stress-related diseases in Sweden have doubled since 1997. Even longterm sickness related tostress has increased over the last decade. In future there is a need of alternative methods todecrease the amount of people being affected to gain a better population health. Natureassisted therapy (NAT) was shown to be a successful method as part of the therapy of stressand burnout likewise was nature an important factor to prevent people from mentaldisorders. The aim of this study was to analyse the latest research concearning nature and itshealth effects with focus on stress and burnout patients in order to plan health promotingactivities outdoors for these patients.

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The development of farm-operated biogas plants in Sweden is increasing. This study investigates the process that firms go through in developing such ventures. The aim is to identify obstacles and opportunities that individual farmers have encountered during the implementation process, and through a comparative analysis find similarities and differences between cases. The overall goal is to increase understanding of the factors that influence farmers? development of farm-based biogas production, and more specifically, explore opportunities for support organizations to contribute to the innovation process. Findings indicate that the implementation process has changed over time.

För pedagoger är det viktigt att se det som skapar framgång och ger positiv perspektiv.Min undersökning kan hjälpa till att fördjupa förståelsen för vilka faktorer som främjar utbildning för hållbar utveckling. Syftet med studien är att ta reda på faktorer som är viktiga för att främja och förbättra utbildning för hållbar utveckling. Enligt styrdokumenten är hållbar utveckling en nödvändig komponent i utbildning. Materialet erhölls genom kvalitativa djupintervjuer med 6 lärare, inkluderar förskollärare, grundskollärare, gymnasielärare, representanter från Håll Sverige Rent, Naturskolan som har av erfarenhet i praktiskt arbete med hållbar utveckling inom framgångsrikt Grön Flaggs certifieringsprogram. Det analyserades och sammanställdes sedan i löpande text.

The population growth in Europe and with that in Sweden was enormous under 18th century. The results became housing shortage in large part of Europe. Tight residency/ inhabited, poverty and emigration were series of social questions in Sweden. Private house (egnahem) as in the beginning was an idea from England and Germany became a political measure and the answer at those miserable social circumstances in Sweden. The purpose with the private house (egnahem) was to help those new people moved in to towns with place to live and counteract movers to towns and emigration. With the governmental loan and land availability that some municipalities and wealthy people contributed with, could people get a place to live with the small garden. The city garden (trädgårdstaden) with their future idealistic idea/utopia, English gardens, ideas with roots in the old-fashioned gardens (allmogeträdgårdar) and lots of books and periodicals were the source of inspirations. From these the private house gardens (egnahemsträdgårdar) were born. Object for my study is my and my family?s own house in Limhamn, south west of Malmö which was built in 1912 under private house gardens era. The garden and the building have still trace and element from the time of private house. My suggestion is inspired by the private home style with a new thinking design that answers to daily need and the busy life style; a rather easy to maintain for green environment. A more relaxing and peaceful garden with simple design, a garden despite that it is surrounded by neighbours and streets invites in harmony and dreams..

The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.
