Preview An energy efficient building for the Arctic climate

P PP e ee t tt During the past few decades, there has been quite some development of energy efficient buildings with ra V ra Vra V low energy heating consumption; one of these buildings is a passive house which has been successfully la lala implemented in locations 40° to 60° Northern latitudes. Nowadays, there is a focus on implementation dy dydy of a passive house in more demanding climate of the Arctic regions. The analyses presented in this thesis ko koko offer a theoretical possibility of building a fundamental passive house in the Arctic and an improvement va vava of the technical solutions in a full sense of definition. Furthermore, a discussion of the new definition is presented based on the optimization of building construction products and adaptation of a passive house An energy efficient building in the Arctic. The adaptation of a passive house in the Arctic is based on the best combination of building design for the Arctic climate A AA aspects, climate characteristics, the material availability and energy resources combined with ecological n nn impacts. e e e n nn e ee rg rgrg Is a passive house sensible solution for Greenland? y yy e e e ffi ffiffi c cc ie ieie n nn t tt b b b u uu ild ildild ing inging Petra Vladykova f f f o oo r rr t t t h hh e ee A A A rc rcrc t tt ic icic c c c lim limlim a aa t tt e ee - Is - Is - Is PhD Thesis a a a pa pa pa Department of Civil Engineering s ss s ss iv iviv 2011 e ee h h h o oo u uu s ss e ee s s s e ee n nn s ss ible ibleible DTU Civil Engineering Report R-243 (UK) s s s April 2011 o oo lu lulu t tt io ioio n nn f f f o oo r rr G G G re rere e ee DTU Civil Engineering n nn la lala Department of Civil Engineering n nn d dd Technical University of Denmark ? ??

The study described in the thesis has been carried out from August 2007 to April 2011. It should be noted that a leave of absence for a total of 8.5 months has occurred during the process of working on the thesis. The funding for this Ph.D. is from the Technical University of Denmark. The work has been conducted at BYG - Section for Building Physics and Services, Department of Civil Engineering, Technical University of Denmark. The supervisors were Head of Section Professor Carsten Rode (BYG DTU), Associate Professor Toke Rammer Nielsen (BYG DTU) and M.Sc. Søren Pedersen (Passivhus.dk, Passivhus.fi).

The passive house optimisation follows the main design rule in the Arctic and this is focused on minimizing the heat loss before maximizing the heat gains followed by the optimisation of the essential building elements and the implementation of the necessary equipments in the cold regions such as a highly efficient ventilation system with heat recovery. Furthermore, the implementation of a passive house concept in a cold climate needs to be based on sensible solutions regarding material use, and, on a practical level, using available technologies and resources. The adaptation of a passive house in the Arctic needs to take into account also different socioeconomic conditions, building traditions and use of buildings, survival issue, sustainability and power supply, among others. In the Arctic, the energy efficient house based on a passive house concept offers a sustainable solution to the operation of the building with regarding the heating and the consumption of electricity, but, the energy, money investment and CO footprint needed to build 2 such a house would be demanding. Yet, using these energy efficient buildings, there is an opportunity to improve indoor climate, health and security towards extreme climate for the inhabitants in the Arctic areas. Furthermore, the development and usage of extremely energy efficient buildings in the Arctic can lead to new experiences with extremely well-insulating building components, airtight constructions and well-functioning ventilation systems. .smetsys noitalitnev gninoitcnuf-llew dna snoitcurtsnoc thgitria ,stnenopmoc gnidliub gnitalusni-llew ylemertxe htiw secneirepxe wen ot dael nac citcrA eht ni sgnidliub tneiciffe ygrene ylemertxe fo egasu dna tnempoleved eht ,eromrehtruF .saera citcrA eht ni stnatibahni eht rof etamilc emertxe sdrawot ytiruces dna htlaeh ,etamilc roodni evorpmi ot ytinutroppo na si ereht ,sgnidliub tneiciffe ygrene eseht gnisu ,teY .gnidnamed eb dluow esuoh a hcus dliub ot dedeen tnirptoof 2OC dna tnemtsevni yenom ,ygrene eht ,tub ,yticirtcele fo noitpmusnoc eht dna gnitaeh eht gnidrager htiw gnidliub eht fo noitarepo eht ot noitulos elbaniatsus a sreffo tpecnoc esuoh evissap a no desab esuoh tneiciffe ygrene eht ,citcrA eht nI .srehto gnoma ,ylppus rewop dna ytilibaniatsus ,eussi lavivrus ,sgnidliub fo esu dna snoitidart gnidliub ,snoitidnoc cimonoceoicos tnereffid osla tnuocca otni ekat ot sdeen citcrA eht ni esuoh evissap a fo noitatpada ehT .secruoser dna seigolonhcet elbaliava gnisu ,level lacitcarp a no ,dna ,esu lairetam gnidrager snoitulos elbisnes no desab eb ot sdeen etamilc dloc a ni tpecnoc esuoh evissap a fo noitatnemelpmi eht ,eromrehtruF .yrevocer taeh htiw metsys noitalitnev tneiciffe ylhgih a sa hcus snoiger dloc eht ni stnempiuqe yrassecen eht fo noitatnemelpmi eht dna stnemele gnidliub laitnesse eht fo noitasimitpo eht yb dewollof sniag taeh eht gnizimixam erofeb ssol taeh eht gniziminim no desucof si siht dna citcrA eht ni elur ngised niam eht swollof noitasimitpo esuoh evissap ehT .tpecnoc esuoh evissap a morf devired si gnidliub gnimrofrep ygrene lamitpo eht ,snoitagitsevni eht no desaB viii xi Resume ereminim ta åp teresukof re ted go ,sitkrA i nelger ngised etsgitgiv ed regløf gniremitpo suhvissaP .tetpecnok suhvissap arf gningyb egissæmigrene elamitpo ned remmats ,reslegøsrednu åp teresaB .sitkrA i dehgidår lit re red reigolonketsnegningyb ed tmas ,reidræv ngised edneggældnurg Arktis er klimatisk meget forskellig fra et tempereret klima.
