 diskuterats flitigt, såväl på det nationella planet som på EU-nivå. Trenden pekar på ettbyggande där allt större vikt läggs vid den byggda miljöns energiprestanda. Redan idagsläget finns flera exempel på hus med ett mycket lågt energibehov, och antaletlågenergihus växer för varje år.I skrivande stund ligger kraven på bostäders specifika energianvändning på 110 kWh/m2år i Stockholm, men redan till nästa år finns förslag på att minska motsvarande siffra till90. Energimyndigheten genomför just nu ett arbete med att tolka EU:s direktiv om såkallade Nära nollenergihus och de preliminära resultaten indikerar att kravnivån för köptenergi kommer hamna kring 55 kWh/m2 år, vilket är i nivå med de rekommendationersom i dag återfinns i FEBY:s Kravspecifikation för Passivhus.Med utgångsläge i ett uppfört lågenergihus i Henriksdalshamnen i Stockholm har vi iarbetet analyserat olika energieffektiviserande åtgärders inverkan på effekt- ochenergibehov. Även de ekonomiska aspekterna förknippade med åtgärderna har studeratsmed hjälp av en modell för livscykelkostnader.Åtgärderna studerades inledningsvis individuellt för att ge en bild av hur stor påverkan dehar var för sig.

De senaste åren har drivkraften för forskning inom trådlösa sensornätverk ökat markant. Detta är framförallt på grund av de potentiella fördelar som den nya tekniken tillhandahåller. Vi har efter förfrågan av Ivan Kruzela tagit på oss uppgiften att skapa en laboration som är tänkt att ingå i den andra årskursen för högskoleingenjörerna i Data- och Telekommunikation på Centrum för Teknikstudier (CTS), Malmö Högskola. Laborationen handlar om routing och är den tredje i raden av laborationer med trådlösa sensorer. Protokollet som används heter XMesh och är tillverkat av Crossbow Technology. Ambitionen är att laborationen ska leda till förståelse för hur routing uppstår i trådlösa sensornätverk, med avseende på parametrar och andra faktorer som påverkar nodernas val av rutt. Examensarbetet resulterade i en laborationshandledning med tre tillhörande bilagor..

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..

This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad atKTH. The task of the course is to design a small house at a given location and also implement adeepening study. The house in this report is located in Kiruna in the north of Sweden, where theclimate is much colder than in the rest of the country.The deepening study of this report is to evaluates how realistic passive housing north of thePolar Circle is based on those facts. The house will to some extent be designed to fit the passivehousing standard.

In this essay, we have compared a conventional house to a passive house. The housesshared the same local conditions; they have the same living area and the same layout. Thedifferences between the houses were the different construction solutions for the roof, theouter walls, the floor and the heating system. Both the houses qualify the standards fromBBR and the passive house also lives up to FEBY?s special conditions.The purpose with the essay was to examine if it really is profitable to build small hoses aspassive houses.

The passive house concept has been known for many years, but it is not yet verywell known in Sweden. The increased energy requirements places greaterdemands on our buildings and to meet these requirements, passive houses is agood option.Svenska Bostäder have built passive houses with good results and intend tocontinue design some of their new buildings as passive houses. This study ismeant to support Svenska Bostäder in their planning of new buildings byanalyze and compare the different frameworks and building shells of passivehouses.In the first chapters (1,2 and 3) we presents the conditions for passive housesand the differing objects we have examined more generally for the reader tobecome familiar with the concept and the objects.The subsequent chapter presents an analysis of each object partial based on thespecifications from FEBY and finally, in Chapter 5, you will find a table ofvalues where the objects are put into relation to each other and valued there by,together with a brief explanation for the table.This chapter also contains texts on the environment, design and futuredevelopment which all includes our own thoughts and reflections.Finally, the gist of the whole work and our conclusion is presented anddiscussed.On the whole, the work has been very enlightening for us and we hope that theconcept of passive houses have a wider impact in the future..

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..

Ett passivhus är byggt av stomentreprenör företaget Strängbetong i Vara med ventilation och uppvärmning i samma system som kallas för Termodeck. Uppvärmningen sker genom att tilluft från ett FTX-aggregat förs igenom håldäcksbjälklag som värmer upp bjälklaget. Med det erhålls ett ?värmegolv och värmetak?. För ett sådant system behövs en byggnad med tung betongstomme.Energibalans beräkning har gjorts med IDA program och schablon värden från olika kravspecifikationer som visar simulerade värden.
