Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good Indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good Indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Hur ser Läget ut egentligen? : En studie om arbetsmiljön inom byggsektorn
This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.

Inneklimatet på ett kontor : Undersökning av inneklimatet vån. G4 stadshuset samt kontor på Ånghammargatan
This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.
Trädgårdsdesign för hörselskadade : anpassad utemiljö för elever vid Silviaskolan i Hässleholm
There is a lot written about being hearing impaired. There are guidelines on how to adjust the Indoor environment for the hearing impaired. There is even more written about gardening and garden design from different aspects. However, I found out that there is nothing written about garden design or adjusting the outdoor environment for the hearing impaired. At the background of myself being hearing impaired and garden designer I realised that I actually had adjusted my own garden out of the fact that I am hearing impaired.
Förskolegård för ett Reggio Emilia inspirerat tankesätt :
The shape and arrangement of the outdoor environment at a preschool has a critical
impact on the possibilities to practice different pedagogic activities (Grahn et al.1997). At the preschool at Edwin Ahlqvists road, the employees are inspired by Reggio Emilia in their way of thinking, and they consider their outdoor environment is not suitable for the pedagogic activities they use. Reggio Emilia is a city in the north of Italy (Wallin 2001). The preschools there are famous for their pedagogy, their creativity and their democratic way of working (Dahlbech & Johansson 1986). The Reggio Emilia pedagogy is constantly renewed and developed, but with the children?s needs in focus and simultaneously with the quick changes of the modern society.
Miljöstyrning i Riksbyggens ombyggnadsprocess med hjälp av Miljöbyggnad
How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the Indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.
Ideon Forskningspark : yttre arbetsmiljö i ett industriellt landskap
Abstract
Ideon Science Park was built on the edge of Lund city in mid-80ies. The Science Park was surrounded by open farm land and Lunds Faculty of engineering(LTH). The architecture, the facades of the buildings, were placed to face the faculty.
The Science Park has since then grown, and the actual front of the building is no longer faced towards LTH. The people working at Ideon are met by the backside, the meeting with Ideon is primarerly a meeting with fields of parkinglots.
The initiative to this thesis was taken by Ikano Fastigheter AB, one of two real estate owners of Ideon Science park. Their aim is to make the area easier to orientate, they want it to be more internally connected and with a stronger identity.
The thesis is mainly dealing with two questions conserning Ideon Science center.
Allergifritt boende genom val av invändiga ytmaterial
The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.
Inverkan av utfodringsnivå och miljö på reproduktion och hållbarhet hos rekryteringskvigor :
This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.
Identifiering av merva?rden i EPC-projekt
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the Indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and Indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början
This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.
Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment
This study examines the use of building modeling and energy simulations in the design process of a building. The take-off point is the notion of energy simulations being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines, such as the architect and the energy specialist, would create smoother workflows, which would reduce this cost and open up for more frequent and iterative energy simulation processes. The study is an assessment of the modeling tool Revit and the simulation tool Virtual Environment and whether they can create smoother workflows, and make leeway for a more frequent use of energy simulations throughout the design process. It also investigates the limitations of what can be examined by simulations in Virtual Environment. This will hopefully help clarify the future role of energy simulations in design processes. The method is a trial by error approach of testing the two software tools by building and simulating a model. The results of these tests show that the workflow is not optimal (and therefore time consuming) for frequent and iterative simulations throughout the design process, but it also reveals some great possibilities of what can be performed with these two powerful tools at hand. Further development with regards on platform independency of the building information model, including seamless exporting and importing, seems necessary to strengthen the future role of energy simulations..
Arbetsmiljöarbete och ansvarsförhållanden enligt arbetsmiljölagen
This study deals with work environment from a legal perspective. The study includes legislative history, legislation today and one empirical study. The legislation that concerns work environment (health and safety) in Sweden today is found in the Swedish Work Environment Act (WEA), the Work Environment Ordinance (WEO), Provisions issued by the Work Environment Authority, related legislations and also collective agreements. The WEA, passed by the parliament in 1977, came into force on the 1st of July 1978 and it defines the framework for Provisions issued by the Work Environment Authority, which is an authority superintended by the Swedish government. These Provisions contain more detailed stipulations and obligations with reference to the working environment.
