The operas by playwright W. S. Gilbert and composer Arthur Sullivan have been considered some of the most popular and successful pieces of musical theatre in the English language. While their joint creative output neared perfection, Gilbert and Sullivan's working relationship was fraught with conflict. The two men's opposing personalities led them to favor disparate styles and work towards different goals. However, the ability to balance contrasting tones, such as sarcasm and sympathy, resulted in their overwhelming success. I analyze this "winning formula" by looking at the influence of feminism, especially the "New Woman" literary movement, on the works of Gilbert & Sullivan. Gilbert frequently used common female stereotypes and gave his female characters humorous yet demeaning flaws that kept the audience from fully admiring them. Sullivan, on the other hand, countered Gilbert's derisive attitude by composing sophisticated music for the female characters, granting emotional depth and a certain level of respectability. The struggle between Gilbert's mocking tone and Sullivan's empathetic music led to the men's ultimate success. I examine Gilbert's female characters, explore the counteractive effect of Sullivan's music, and analyze Princess Ida—their opera most directly related to the New Woman—in depth.

The construction sector today accounts for 20 precent of Sweden's climate impact and 40 percent of energy use. This purpose of this study is to identify the most effective measures to reduce the grocery store's energy needs. The building is tempered primarily with district heating respectively district cooling that operates the air units' cooling and heating batteries. There are many efficiency measures that are feasible for grocery store's energy usage. This study calculates a under construction grocery store's energy needs and analyses which measures can reduce the total need for purchased energy. This study calculates both property energy and industry energy and then compare the economy and environmental impact of the various measures. This store has also been environmentally certified according to the Sweden Green Building Council system. The simulation program IDA ICE is an effective tool that allows information in the form of energy analysis to be evaluated. This study compares the retail chain's own energy solutions with new innovative solutions that can save energy and money. This study's focus is on energy saving measures from ventilation systems, cooling systems and heating systems. Measures examined in this study are: •         Solar cells on the property's roof •         Additional insulation of ceilings and floors •         Heat recovery of the grocery refrigeration system •         Heat recovery of the industry ovens The total property energy was 2,000 MWh or 150 kWh/m2. Heat recovery of the cooling system saves 500 MWh annually, which corresponds to 37 kWh/m2. Installation of 4,000 m2 of solar cells saves 480 MWh, which corresponds to 35 kWh/m2. The measure that is most optimal from an energy point of view is heat recovery from the refrigeration system. The measure that is most economically profitable is the installation of solar cells. The measure that saves the most carbon dioxide is heat recovery from the refrigeration system. The comparison showed that heat recovery is the most profitable measure. After the implementation of all measures, the store reaches Swedish environmental class "environmental building gold".

The building sector is one of the sectors that consume most energy in Sweden. Sweden aims thereby to reduce energy use in buildings by 20% by 2020 and 50% by 2050. To achieve these goals, more energyefficient buildings must be produced, and more energy-efficient measures must be implemented on existing buildings. Electrochromic windows are claimed to reduce the need for heating and cooling, as well as the need for artificial lighting. However, there is limited research on smart windows in the Nordic climate.   This thesis examines electrochromic windows in Sweden, using the IDA ICE 4.7.1 simulation program. The study includes a comparative analysis of an office building model with conventional windows and motorized awnings, versus electrochromic windows with different control strategies, to investigate the building’s impact. In total, eight different scenarios are simulated in Stockholm, Umeå and Malmö. The electrochromic window scenarios consist of control algorithms where the windows are always on or off, as well as algorithms that respond to sunlight, daylight, operative temperature or scheduling. The conventional windows and awnings scenario represents the reference building. The Swedish building certification system "Miljöbyggnad" is used as a guideline for evaluating energy use, heating power demand, solar heat load, thermal climate, and daylight.   The results show that electrochromic windows have little impact on the building. None of the scenarios succeed in obtaining higher certification than BRONZE, which corresponds to the authority's requirements for newly built buildings. However, electrochromic windows have a significant effect on the solar heat load and the lux level in the building, but unfortunately not enough to get a better building grade. There is no remarkable difference between the indicators and scenarios. Furthermore, the results show that scenarios that are shaded often (Always on, Daylight Control, Solar Control strategy) achieve GOLD ratings in solar heat load, but have the least impact on energy consumption and vice versa. Always off, Operative Temperature Control, and Schedule, Façade and Window strategy upgrades by one level in energy use. This confirm previous studies that claim that electrochromic windows have the greatest potential in energy saving in hot climate. This explains why there is hardly any difference between scenarios and cities.   The thesis lacks specific costs for electrochromic windows. Thus, the cost estimate is based on generalizations and assumptions, in which the cheapest and most expensive options are investigated. If the building has well-functioning windows and awnings, it is not cost effective to switch to electrochromic windows, since the payback time is far too long. But if the building was between conventional windows and electrochromic windows during the planning phase, it might be interesting to conduct a detailed cost analysis. According to this study, the Operative Temperature Control strategy saves approximately 6 333kr during the simulation period. The cost differences between conventional windows with motorized awnings, and the cheapest version of electrochromic windows is around 60 000kr. This would provide a refund within 10 years, given that energy prices, energy consumption and currency value are the same. After that, the window would cut the energy costs in the form of saved energy.   However, the study concludes that electrochromic windows are not necessary in this project from a Miljöbyggnad perspective, since the building grade remains the same and the economic gain is uncertain. / Byggnadssektorn är en av de sektorer som använder mest energi i Sverige. Därmed har Sverige som mål att minska energianvändningen i byggnader med 20% år 2020, och 50% år 2050. För att uppnå dessa mål måste fler energieffektiva byggnader produceras, samt fler energieffektiva åtgärder måste genomföras på befintliga byggnader. Elektrokroma fönster hävdas minska behovet av uppvärmning och kylning, samt behovet av artificiell belysning. Det finns dock begränsad forskning om smarta fönster i det nordiska klimatet.   Detta examensarbete undersöker elektrokroma fönster i Sverige, med hjälp av simuleringsprogrammet IDA ICE 4.7.1. Arbetet omfattar en jämförande analys av en kontorsbyggnadsmodell med vanliga fönster och motoriserade markiser, kontra elektrokroma fönster med olika kontrollstrategier, för att undersöka byggnadens påverkan. Sammanlagt simuleras åtta olika scenarier i Stockholm, Umeå och Malmö. De scenarier med elektrokroma fönster består följaktligen av kontroll algoritmer där fönsterna är alltid på eller avstängda, samt algoritmer som reagerar på solljus, dagsljus, operativa temperatur eller schemaläggning. Scenariot med vanliga fönster och markiser representerar referensbyggnaden. Det svenska byggnadscertifieringssystem ”Miljöbyggnad” används som riktlinje för evaluering av energianvändning, värmeeffektbehov, solvärmelast, termiskt klimat, och dagsljus. Resultaten visar att elektrokroma fönster har liten påverkan på byggnaden. Ingen av scenarierna lyckas få högre certifiering än BRONS, vilket motsvarar myndighetens krav på nybyggda byggnader. Dock så har elektrokroma fönster signifikant inverkan på solvärmelasten och lux nivån i byggnaden, men tyvärr inte tillräckligt för att få ett bättre byggnads betyg. Det är ingen anmärkningsvärd skillnad sinsemellan indikatorerna och scenarierna. Vidare visar resultaten att scenarier som är skuggade ofta (Alltid på-, Dagljuskontroll-, Solljuskontrollstrategin) uppnår GULD betyg inom solvärmelast men har minst inverkan på energiförbrukningen och vice versa, Alltid av-, operativa temperaturkontroll, samt schemaläggning, fasad och fönster strategin uppgraderas ett steg inom energianvändning. Detta styrker tidigare studier som påstår att elektrokroma fönster har störst potential i energibesparing i varma klimat.   Detta förklarar den minimala skillnaden av byggnadens påverkan mellan städer och scenarier. I denna rapport saknas specifika kostnader för elektrokroma fönster. Därmed baseras kostnadsuppskattningen på generaliseringar och antagande, där billigaste och dyraste alternativet undersökts. Om byggnaden har väl fungerande fönster och markiser, är det inte kostnadseffektiv att byta till elektrokroma fönster, då återbetalningstiden är alldeles för lång. Men om byggnaden stod mellan vanliga fönster och elektrokroma fönster i planeringsfasen kan det vara intressant att göra en noggrann analys. Enligt denna studie så sparar den Operativa Temperatur strategin ca. 6 333kr per år. Det skiljer ca 60 000kr mellan vanliga fönster med markiser, och elektrokroma fönster. Detta skulle ge en återbetalning inom 10 år förutsatt att energipriserna, energiförbrukningen samt valuta värdet är desamma. Därefter skulle fönstret minska utgifterna i form av sparad energi.   Slutsatsen är dock att elektrokroma fönster inte är nödvändiga i detta projektet från en Miljöbyggnads synpunkt, eftersom att det inte förbättrar byggnadsbetyget. Dessutom kvarstår osäkerheten med kostnader.

Sweden uses a large amount of energy within the housing and services sector and there is a greatneed to reduce the energy usage & heat demand of buildings. Using environmental certifications it ispossible to reward buildings that are dimensioned for lower energy usage and low heat demand fromrequirements demanded by the Swedish National Board of Housing, Building and Planning(Boverket). Miljöbyggnad 3.1 (Swedish Green Building Council) Indicator 1 Heat demand is todayassessed in relation to the inside enclosing area of the building, W/m2,Aoms, while Indicator 3 Energyusage is assessed in relation to heated floor area, kWh/m2,Atemp. Previous research indicates that thesequantities do not take into account how well the building is used but only how well it is dimensionedin terms of construction technology. Therefore it might be appropriate to introduce a quantity thattakes into account how well the building is used. The purpose of this case study is to raise a discussion if Boverket and Miljöbyggnad 3.1 today usessuitable quantities when it comes to grade energy efficient building and how different quantities cancome and affect a grading. This research presents a case study where an elementary- and a preschool using IDA ICE-modelsevaluates based on simulations for energy usage and heat demand. The results from the simulationsare compiled in diagrams to be able to see how different cases affect the grading based on whichquantities are being used. The quantities that are being used in this study is based on previousresearch and the different cases have been made to see which parameters affect the quantities. The study shows that depending on what is considered to be an energy efficient building, differentquantities may be applied for the assessment. The quantities used today in Miljöbyggnad 3.1 forIndicator 1 Heat demand and Indicator 3 Energy usage favors different types of buildings.kWh/m2,Aoms favors buildings with higher floor heights while kWh/m2,Atemp favors buildings withlower floor heights.

This report is an exploratory and comparative study of Boverkets constitution BEN1. In this study the constitution BEN1 is examined, why the constitution was established, when is it applicable and what advantages and disadvantages will come with it. Today the housing and service sector is using a major part of Europe’s final energy use, in addition to this, these sectors also represents a major part of the total carbon dioxide emissions. The EU-commission aims to reduce the housing and service sectors energy use and emissions. In 2002 the European parliament established directives and demands for buildings energy performance. These directives were changed in 2009-2010, which led to an inspection of the already existing Swedish constitution, this was found to be inadequate by the EU-commission. Sweden decided to create a new constitution in order to satisfy EU’s new directives and demands. The focus is on a normal usage of the building in a normal year in the new constitution, BEN1.  The reader should receive an idea and understanding about BEN1 and why it was established in this report. Beyond this, the study will show the changes that happen to a buildings energy performance after the constitution is applied and what advantages and disadvantages this could bring.  This study was performed by simulating the buildings energy use with the input from BEN1 in a simulation tool, IDA Indoor Climate and Energy.  The study shows that the energy performance will change but it also shows that further studies should be made in order to obtain a more carefully drawn and common conclusion. / Detta är ett examensarbete på grundnivå (kandidatexamen), 15 högskolepoäng. Examensarbetet är en utredande och jämförande studie av Boverkets senaste författningssamling BEN1. I denna studie utreds BEN1, varför det upprättades, när det ska tillämpas och vad det medför i fråga om för- och nackdelar.   Idag utgör tjänste- och bostadssektorn en stor del av Europas slutliga energianvändning och totala koldioxidutsläpp, något som EU-kommissionen har som mål att minska. Minskningen skulle ske med tillämpning av Europaparlamentets direktiv och krav gällande energideklarationer som kom år 2002. Direktivet omarbetades under 2009-2010 vilket ledde till en granskning av det befintliga svenska regelverket, EU-kommissionen fann detta bristfälligt och beslutade därför om ett överträdelseförfarande. Sverige svarade på överträdelseförfarandet med den nya författningssamlingen BEN1 som handlar om fastställande av byggnaders energianvändning vid normalt brukande och ett normalår.  I denna rapport ska läsaren få en uppfattning om och förståelse kring Boverkets författningssamling BEN1 och varför den upprättats. Utöver det ska studien påvisa förändringarna som sker hos en byggnads energiprestanda vid tillämpning av BEN1 samt upplysa läsaren om vilka för- och nackdelar tillämpningen av BEN1 kan ge. Studien har utförts genom att simulera byggnadernas energianvändning, enligt BEN1s föreskrifter och allmänna råd, i IDA Indoor Climate and Energy, ett simuleringsverktyg. Studien visar att en byggnads energiprestanda kommer att förändras men att vidare studier bör göras för att en mer noggrann och allmän slutsats ska kunna erhållas. De största förändringarna gällande energiprestandan har skett i byggnadens behov av värme och varmvattenberedning, detta efter tillämpande av de schablonvärden BEN1 erhåller. Resultaten som erhålls i denna studie är enligt BEN1 validerade värden för byggnadernas energiprestanda.

Idag står bostads- och servicesektorn för närmare 40 % av Sveriges totala slutliga energianvändning. Flerbostadshus utgör ca 30 % av den energianvändningen. Därför är det viktigt att lokalisera energiparametrar och redovisa dess betydelse för energianvändningen. Samtidigt bör relationen mellan energianvändning och inomhusklimat analyseras, så att inte förändringar i energin medför till försämringar för inomhusklimatet. Baserat på identifiering hos energisparpotentialen hos parametrar, parameterbeteende och parameterkänslighet för energianvändning har i studien ett antal parametrar undersökts för ett flerbostadshus. Även parametrarnas betydelse för det termiska klimatet har utifrån de parametrar som visat sig ha störst energisparpotential studerats. Studien är tänkt att komma till nytta för presentation av energisparpotentialer och beaktande hos indataparametrar vid energiberäkningar, samt öka förståelsen för hur termiska komforten påverkas av olika parametrar. En referensbyggnad har modellerats i programmet IDA ICE 4.5 och typisk spridningen för olika parametrar för byggnader från år 1970 till nutid har varierats och jämförts med ett referensfall. För det termiska klimatet har kriterier enligt certifieringsprogrammet Miljöbyggnad utnyttjats. Resultatet visar att ventilationssystem har stor energisparpotential. Vid en övergång från F-system till FTX-system görs betydande energibesparing, samtidigt som det sker en förbättring av den termiska komforten. Inomhustemperaturen har visats sig vara den känsligaste parametern vid beräkning av energianvändning. För den termiska komforten är fönsters g-värde och inomhustemperatur viktiga parametrar att beakta. Resultatet av energi- och komfortsimuleringarna visar också på en tydlig korrelation mellan energianvändning och termisk komfort. / Building stock consumes 40 % of total energy usage in Sweden, dwellings contribute almost 30% of the proportion. With an interest on the parametric analysis and its corresponding energy saving potentials, the investigation on the sensitivity of selected building parameters in a typical Swedish slab house is performed in the study. Based on the identification to the behavior of target sensitive parameters, the upgrading potential of thermal comforts is comparably analyzed with respect to approach the optimization design of further retrofitting scenario and uncertainty guidelines. A slab house built after 1970 is selected as the represented case building with a detailed typology introduction. In the study, IDA ICE 4.5 is applied to perform both the energy simulation and thermal comfort estimation. Based on the local screening analysis and the setting of criterion system, the ranking of the target parameters is rated systematically. The study is meant to be useful for the presentation of energy saving potentials and consideration of input parameters on energy calculations, and increase understanding of how thermal comfort is affected by various parameters. The results show that accomplished with the transformation of F-system to FTX-system, the applicable ventilation system efficiency shows the largest energy saving potential and improved thermal comfort, and the indoor temperature shows the largest sensitivity to the total energy profile. Comparably, along with the indoor temperature, the performance of glazing system in terms of the g-value is recognized as the parameters with the highest consideration. Based on the sensitivity analysis, the correlation between the energy savings and thermal comfort upgrading is verified, which indicate the possibility of providing optimal design scenario for both architectural error guidelines and further building retrofitting.

This report aims to evaluate the potential of sharing energyregarding heat and cooling between buildings in a smalldecentralized energy system. A model of an energy substation wasdeveloped in IDA ICE Advanced level only system to create a timeefficient tool that is easy to handle for people in the industry.Three cases of building stocks with different heating and coolingdemands were modeled in the energy substation, both separately andcollectively, to investigate the differences in energy performanceas a result of energy recovery between buildings. The study also contained a sociotechnical aspect of thedecentralized energy system. Interviews were carried out to studyhow a mutual energy substation is implemented in reality and whatchallenges and opportunities the technology faces. An importantconclusion is that the future development for this new technologyis highly dependent on an increased cooperation between companiesin the industry.The simulations of the cases showed an improved energy performancefor the mutual energy substations in all three cases, sevenpercent improvement as most. The report concludes that there ispotential for an improved energy performance in a building stockwhen implementing a mutual energy substation since it enables theability to save energy through energy recovery. Furthermore, it isconcluded that a resembling heat and cooling demand within thebuilding stock increases the total energy performance of thesystem. An improved control system of the model is recommendedbefore deciding if and where it is beneficial to implement amutual energy substation.

We are currently facing a global climate crisis, which demands that we decrease our energy consumption and carbon footprint. An essential area of focus is the energy optimization of buildings. Purpose: The objective of this study was to assess the current indoor climate within the office building Vråken in Västerås and investigate different measures for the ventilation system and identify potential energy and cost savings. Method: A literature review was carried out to establish the theoretical foundation and examine previous research in the subject area. The staff's perception of the indoor climate within the office building was evaluated through a survey. Relevant information was collected to understand the building's construction and current ventilation system. Further on, a model of the office building was established in IDA ICE to simulate the two selected ventilation measures. Finally, a life cycle cost calculation compared the profitability of the studied measures. Results: The results indicate that the measures have a minor impact on the indoor climate compared to the reference case. Assessing the changes in the indoor climate is challenging due to multiple climate parameters and the simulation results of this study are considered uncertain. The results show that the energy consumption of ventilation can be reduced by 46 or 51%. This corresponds to an annual energy savings of either 122 or 110 MWh, depending on the chosen measure. The first measure, which involves installing zone dampers on each floor, has an estimated investment cost of 92 531 SEK. The second measure, which entails equipping one of the floors with a separate air handling unit, is estimated to cost 388 650 SEK. The profitability assessment shows that the reduction in the total life cycle cost is 2 683 332 SEK for the first measure and 2 631 543 SEK for the second measure. In total, both measures result in a cost savings of 45 or 44% over a period of 25 years compared to the buildings current ventilation system. Conclusions: The results from this study are influenced by several factors with varying degrees of impact, including the existing ventilation system, building model and the assessment of the indoor climate. Despite this, the results indicates that the studied measures can maintain an acceptable indoor climate and at the same time save both energy and costs for the ventilation in the office building.

Detta projekt har som syfte att analysera en kommande renovering av en kontorsbyggnad i Boden under Fortifikationsverkets ägo. Projektet använder sig av programvarorna IDA Indoor Climate and Energy och Revit för att simulera byggnaden som den kommer att se ut efter att renoveringen är utförd. På detta sätt kan Fortifikationsverket utvärdera den utförda renoveringen med referensvärden tillhandahållna av detta projekt. Projektet introducerar läsaren till Revit samt simuleringsprogrammet IDA ICE och visar hur energianvändning kan simuleras för byggnader man önskar renovera. Ritningar, en energibesiktning av huset och uppmätta värden för tidigare år utgör underlaget för simuleringen och där värden inte finns tillgängliga görs antaganden. Den stundande renoveringen består av ett nytt ventilationssystem och strikta riktlinjer satta av Fortifikationsverket följs då renovering utförs. Renoveringen kommer att beröra tätning av byggnaden, sänkning av rumstemperaturer, effektivisering av belysning samt installation av effektivare fläktar, kylaggregat och värmeväxlare. Projektet finner att den stundande renoveringen sänker byggnadens årliga energianvändning med ca 31 %, uppvärmning och elförbrukning ingår i denna energianvändning och sänks med ca 29 % respektive 33 %. Byggnadens årliga uppvärmning och elförbrukning efter renovering fås till 409 009 kWh respektive 446 905 kWh. Av renoveringens olika åtgärder finner projektet att värmeåtervinning i ventilationssystemet hade överlägset störst verkan på uppvärmningen. Angående elförbrukningen hade effektivare belysning och effektivare fläktar störst verkan. / The purpose of this project is to analyze an upcoming renovation of an office building in Boden, owned by Fortifikationsverket. The project makes use of the software IDA Indoor Climate and Energy and Revit to simulate the building as it will function after completed renovation. This way Fortifikationsverket has a reference value to use when evaluating the actual performance of the building. The project introduces the reader to Revit as well as to the simulation program IDA ICE and shows how energy consumption may be simulated when one wishes to renovate a building. Drawings, an energy report and measured energy consumption act as the basis for the simulation and where values are not available assumptions are made. The upcoming renovation consists of a new HVAC system and rules set forth by Fortifikationsverket which are to be followed when a building under their regime is renovated. These rules consists of reducing air leakage, lowering room temperature and installing more effective lightning, fans, heat exchangers and air cooling. The project finds that the upcoming renovation lowers the yearly energy consumption of the building by approximately 31 %, heating and electricity are included in this energy consumption and are lowered by approximately 29 % and 33 % respectively. The yearly use of heating and electricity is found to be 409 009 kWh and 446 905 kWh respectively. Of the various measures taken by the renovation the heat recovery is found to be the most effective. The electricity consumption was lowered most by more effective lightning and fans.
