The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and Ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.
Upphängningssystem
Examensarbetet som utförts på Institutionen för Maskinteknik vid Blekinge
Tekniska Högskola i samarbete med Kockums AB har benämningen ?
Upphängningssystem?.
Dagens upphängning av rör, Ventilationsrör och kabelbanor består av ett antal
olika singelupphängningar utan större samordning. Detta har gjort att Kockums
AB önskat få fram ett samordnat upphängningssystem som klarar av alla dessa
upphängningstyper.
Utifrån denna problemställning har vi arbetat oss fram till ett
upphängningssystem bestående av ett multisystem och ett flertal
singelupphängningar för rör, kabelbanor och Ventilation.
Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård
This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural Ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.
INOMHUSMILJÖ I SMÅHUSMED FTX-VENTILATION : EN LITTERATURSTUDIE MED ENKÄTUNDERSÖKNINGAR OCHMÄTNINGAR
This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.
Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
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.
En studie av fysiska, organisatoriska och individuella riskfaktorer hos arbetstagare med datorarbete
Musculoskeletal disorders (MSD) are common in individuals with computer based work. Thecurrently known risk factors for these disorders is in the literature derived to physical,organizational and individual factors. A recent survey of three working groups at a companyin Stockholm explored that more than 50% of the employees had neck and shoulder problems.Aim: The study aims to create a better understanding for the current musculoskeletalproblems at the company. Such an understanding is created by examining the physical,organizational and individual risk factors in the workplace and the result can provide a goodbasis for intervention proposals.Method: In order to answer the aim of the study the authors chosed to use both qualitativeand quantitative methods of data collection through interviews and questionnaire survey. Theinterview and questionnaire was designed to create both a specific and comprehensive pictureof the physical, organizational and individual risk factors having a bearing effect on theexisting MSD problem.Result: Seven categories were compiled from interviews, which largely deals with the factthat high demands can lead to behaviors that may pose a significant risk for the occurrence ofMSD.
Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.
Grubbe Ventilation AB is a sheet metal and Ventilation company who provides design, installation, service, and repair of Ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.
Att söva den feta patienten- med fokus på ventilationen
Fetma och övervikt är ett hälsoproblem som drabbar mer än var tionde person och antalet individer med BMI >30 ökar ständigt. Som en följd av detta kommer allt fler patienter som genomgår anestesi att ha ett högt BMI. Förändringar i respiration, luftvägsanatomi och ett flertal andra fysiologiska förändringar i kroppen gör generell anestesi för patienter med fetma till en anestesiologisk utmaning. Syftet var att beskriva vilka omvårdnadsåtgärder anestesisjuksköterskan kan använda för att bibehålla god Ventilation hos feta patienter vid generell anestesi. Studien genomfördes som en litteraturstudie där 12 vetenskapliga artiklar analyserades.
Energianvändning i restauranger i Umeå kommun
Efficient energy use in restaurantsUmeå Municipality wishes to combine energy issues with food control, and thus help restaurants to become more energy efficient. During March and April 2010, I visited seven restaurants and interviewed restaurant personnel about current state and application of kitchen appliances, using a checklist to make sure that the same questions were asked at all restaurants. The restaurants were all different sizes and offered different kinds of food. The study mostly focuses on energy efficiency by behaviour and not on location or technology. Almost every restaurant that was visited had the potential to improve in one or more areas, such as kitchen appliances, lamps and lighting fixtures, heating, cooling and Ventilation.
Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal
SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.
Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk
The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.
Antalet dörröppningar under operation och dess orsaker - En Observationsstudie
Bakgrund: Studier har visat att dörröppningar samt rörelse av personal inne på operationssalen ökar mängden bakterier i luften. Vårdrelaterade infektioner är den mest förekommande komplikationen vid kirurgi och skapar onödigt lidande för patienten. Infektionsförebyggande åtgärder såsom Ventilation i operationssalen har betydelse för att minska risken för att bakteriebärande partiklar ska kontaminera luften i operationssalen och åstadkomma infektion i operationssåret. Syfte: Syftet med denna observationsstudie var att studera hur frekvent dörrarna öppnades under pågående operation samt identifiera orsakerna till dörröppningarna. Metod: Data från observationer av 27 operationer har sammanställts och analyserats.
Arbetsmiljöutredning med Åtgärdsförslag för Svetsare vid Svetsning i Koppar : ABB Transformers Plåtverkstad
Examensarbetet har utförts vid ABB Power Transformers i Ludvika i plåtverkstaden, där stora transformatorlådor svetsas ihop. Tillsammans med vår handledare på företaget utformades ämnet för examensarbetet att bedöma luftkvalitet och arbetsmiljö vid punktsvetsning i koppar. Det fanns misstanke om att exponeringen för koppar var hög och en utvärdering av luftkvaliteten behövde därmed göras. Ingen tidigare exponeringsmätning vid svetsning i koppar har genomförts i plåtverkstaden. Syftet med examensarbetet var att utvärdera och komma fram till tre åtgärdsförslag för att skapa en bättre arbetsmiljö vid punktsvetsning samt att begränsa exponeringen av svetsrök som bildas vid svetsning i koppar. Tre åtgärder var företagets önskemål.
Utveckling av ett ventilationssystem för produktionsortar vid skivrasbrytning
Det här examensarbetet har utförts på uppdrag av Malmfalten AB. Malmfalten AB har haft en idé om att utveckla en ny typ av Ventilationssystem för tvärortar (produktionsortar) vid skivrasbrytning. Nuvarande Ventilationssystem kräver att Ventilationsdukarna tas ned från sin plats i orttaket inför skivrasborrning och därefter åter monteras upp. Syftet med detta arbete har varit att skapa ett förslag på en lösning som undviker detta och därmed ger upphov till ekonomiska vinningen och arbetsmiljömässiga fördelar. Följande metod har nyttjats för att framställa ett sådant förslag: intervjuer, observationer, funktionsanalys, kravspecifikation och PUGH:s beslutsmatris.
