Passivhuset i det långa loppet : - hur påverkar brukarens kunskap energiförbrukningen?
The scope of this investigation is to decide how and to what extent the energy consumption of apassive house is affected by the users? knowledge and habits. To achieve this a literary study hasbeen made and as a complement the planning of a passive house was completed.The result of a primary study of the rules and regulations that effect passive houses in Swedenshows that the user?s influence on passive houses is a completely unregulated area. Even thoughthere is no regulation, a need for some general knowledge of the passive house concept has beenexpressed.To further investigate how the users? knowledge and habits affect the energy consumption and ifthere is a difference between different households? energy consumption , three main factors havebeen identified.
Passivhus av helväggselement i träull
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.
Energy analysis of a fruit drying plant in Adeiso, Ghana
The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit
drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying
process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity.
The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.
Projekteringsförslag för JM AB av fastighet 3:2 i Bukärr, Särö
The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.
UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk
Lining techniques such as nap bonding and mist lining were developed in the late 20th century and
have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability
of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown
advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced,
which can be advantageous for more sensitive paintings. These lining techniques have been included
in several studies where reversibility, minimal intervention and respect for the individual requirements
and problems of each object have been the focus. The adaptability of the methods has been confirmed
and to further explore the adaptability, this study consists of three simpler application techniques with
the adhesive Lascaux 303 HV on mockups.
Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån
WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.
Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Aktiviteten hos thymidinkinas 1 i serum från hundar med juvertumörer och malignt lymfom
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
Effektivisering av kylsystem på Utö värdshus
Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

Kommunalt naturskydd som en del av markanvändningsplaneringen : en fallstudie av olika synsätt i samband med upphävande av naturreservat
In metropolitan areas where the exploitation pressure increases, also the importance to point out nature areas grows, both for the sake of outdoor life and for biodiversity conservation. Since nature conservancy and spatial planning constitute two different parts of the municipalities land use control, a case study has been carried out in two municipalities in the Stockholm region, Huddinge and Järfälla. Both these municipalities have protected about one third of their land and today there are plans to repeal parts of the reserves to enable exploitation. This thesis shows ? from the theoretical concept of sustainable development ? officials, politicians and non-governmental organizations perspectives on questions concerning land use together with the work with nature reserves and repeals.

Se men inte röra : Röntgen som verktyg i dokumentation av historiska stoppningar.
How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.
