Byggnadsutformningens inverkan på energianalysen : En jämförande utvärdering av två energisimuleringsprogram
Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..
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.
Ekologisk hållbarhet i den fysiska planeringen, teori till handling :
I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen.
There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice.
My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.
Disclosure Tone in Environmental Reports ?A study of companies in the energy sector
Background and problem discussion: Sustainability reporting has recently risen in importance and a rising number of companies choose to issue voluntary stand-alone sustainability reports. Their non-regulated nature increases the opportunity for management to angle the information in these disclosures to their own advantage. Lately the focus has shifted from examining what kind of information is provided in environmental disclosures, to analyzing how the information is presented.Purpose: The purpose is to examine if managers in the energy sector use optimistic tone when issuing sustainability reports. The aim is to find out if the tone applied in environmental disclosures is in congruence with either the environmental or economic performance or if an excessively positive tone is being used to mislead readers.Limitations: This study is limited to information found in environmental disclosures from private companies in the energy sector, issued in 2012 or 2013. Environmental performance is defined as the amount of CO2e emissions and economic performance refers to annual company revenues.Methodology: The quantification of optimistic tone is conducted using a content analysis, relying on a pre-specified wordlist and a pilot study.
Integrerad hästanläggning : ridhus/stall
Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity.
In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.
På väg mot ett hållbart resande? : En fallstudie kring den lokala kollektivtrafiken i Umeå tätort
Sustainability and the traffics impact on the environment have become increasingly central within spatial planning. For many years, planning has been focusing on building new roads - this has resulted in increased use of automobiles, which many believe is unsustainable in the longer term. Therefore, authorities at national, regional and local level want to increase the use of alternative transport modes ? such as walking, cycling and traveling by bus.The thesis intends to study if the Municipality of Umeå?s policies for sustainable development have led to an increased use of public transportation. The use of public transport in Umeå is also compared with developments at national level, in order to see if there are differences in the level and trend.
Vart jag mig i världen vänder : En studie om konsumenters förhållande till researrangörers CSR
Purpose: To examine how a tour operator works to implement sustainability in the development of the business, as well as what significance it has to consumers in selecting a tour operator. Furthermore, the purpose is to provide recommendations on how tour operators should work to communicate their commitments.Methodology: The research strategy applied is a case study which follows an abductive approach. Qualitative and quantitative methods were applied to complement each other. A semi-structured interview with a tour operator and a consumer survey constitute the empirical foundation.Conclusion: The conclusion of the study is that consumers show a positive attitude towards CSR, but do not see it as a determinant when choosing a tour operator. Thus, CSR does not constitute a competitive advantage against competitors.
Byggnadsminnen och dess försvarbarhet över tid
certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.
Projektering av fårstall :
The purpose of this work was to see if it was possible to rebuild an old dairy house into a house fore sheep production. The goals fore the work was to see witch kind of production model was suitable, how the actual drawing would look like and witch kind of interior was needed.
The building was built in the beginning of 1900. It is located on the mountain Kinnekulle in Sweden. It was a big production fore its time and hade about 60 dairy cows. It was a lot of hard work because the floor was built by big stone blocks and it was very hard to rebuild when some more automatic solutions came fore handling all the manure.
The idea of remaking the building came when we rebuilt the roof fore 5 years ago.
Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet
Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.
Passivhus, detaljutformning och dess köldbryggor
Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.

Förskolor med passivhusteknik : En utredning av passiva förskolor
As a result of directives from EU, with the ambition to reach environmetal goals, The German organisation Passivhaus Institut has defined a passive house. A passive house is a building that is very energy efficient and makes a small impact on the environment. The energy from the inhabitants as well as the appliances & fixtures in the building should equal the energy that is required to heat the building. A Swedish version of the passive house definition has been defined, taking into account the climate conditions and the difference in building regulations.This thesis is a request from Skanska on how it can improve and develop an ongoing passive house project, involving an infant school. The intention of this thesis is to identify difficulties & display potential development areas for infant schools.The method of research conducted is as follows: interviews of clients, ventilation consultant, consultant for heating system and an energy calculation consultant, an inspection of the infant shcool in process, investigation of completed infant schools and a study of relevant literature.From this research it was found that it is difficult for infant schools to pass the criteria for passive houses. The conclusion of this thesis provide several guidelines on how to improve the outcome of existing projects & the steps needed to be taken for future development in this area..
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..
