Abstract

Trajnostna gradnja se vse bolj uveljavlja kot način koncipiranja in gradnje stavb. Cilj raziskave je bil preučiti primerjavo vseživljenjskih stroškov sistemov ogrevanja, hlajenja, prezračevanja in rabe vode dveh zasnov stavb, klasične in trajnostne. Klasično zasnovo stavbe predstavlja stavba s plinskim kondenzacijskim kotlom ter radiatorji za ogrevanje, ''split'' napravo za pohlajevanje prostorov, z naravnim prezračevanjem prostorov ter dovodom vode za sanitarne potrebe, pitje, kuho, pranje vozil in zalivanje vrta. Trajnostno zasnovo stavbe predstavlja stavba z vertikalnim zemeljskim kolektorjem, ki koristi obnovljivi vir - energijo zemlje. Za ogrevanje je toplotna črpalka priključena na vertikalni zemeljski kolektor in sistem talnega gretja, za pasivno hlajenje pa je vertikalni zemeljski kolektor priključen na sistem talnega gretja. V sistemu prisilnega prezračevanja se koristi toploto odpadnega zraka. Za potrebe izpiranja WC kotličkov, zalivanje vrta in pranje osebnega vozila se koristi odpadna voda (deževnica). Eksperimentalno delo je vključevalo analizo neto sedanje vrednosti obeh zasnov stavbe, trajnostne in klasične z upoštevanjem stroškov rabe virov, obratovanja in vzdrževanja sistemov in naprav. Rezultati raziskav magistrske naloge so uporabni v praksi. Ugotovili smo, da je sistem ogrevanja s toplotno črpalko vezano na vertikalni zemeljski kolektor, ekonomsko sprejemljiva rešitev, ter da sistem z vračanjem toplote odpadnega zraka in sistem koriščenja deževnice za uporabo v gospodinjske ter sanitarne namene trenutno ni najbolj ugodna rešitev. Lahko pa ob povečanju cen energentov in/ali virov, postaneta obe možnosti ekonomsko sprejemljivi in zaželeni rešitvi.

Secondary title: LIFE CYCLE COST ASSESSMENT OF ENERGY CONSUMPTION OF A CLASSICAL AND SUSTAINABLE RESIDENTIAL BUILDING CONSTRUCTION
Secondary abstract: Sustainable building is more and more becoming a way of conceiving and building construction. The aim of the study was to study the comparison of lifelong costs of heating, cooling, ventilation and water use of two building concepts, sustainable and /traditional. Traditional design of the building represents the building with a condensing gas boiler and radiators for heating, ''split '' device for cooling, nature ventilateing the rooms, and domestic water supply for drinking, cooking, washing vehicles and watering the garden. Sustainable design of the building represents a building with vertical collector for usage of ground energy, which exploits renewable energy source - energy of the earth. The installation typically consists of a vertical ground collector bound to a heat pump and underfloor heating system for heating the building. On the other hand a vertical ground collector bound to underfloor heating system for pasive cooling of the building. Ventilateing system uses heat of exhaust air. Additionally the rainwater (as an renewable, sustainable and good quality water source) is foreseen for the purpose of flushing toilets, watering gardens and washing vehicles. Experimental work comprises analysis of the net present value for the two concepts of building - a sustainable and traditional, taking into account the costs of resource exploitation, operation and maintenance of systems and devices. The results of the study represent a case study with high potential in practical implementation. It was established that the heating system with a heat pump bound to the vertical ground collector represents an economically viable solution while the air heat recovery system as well as use of rainwater in household and sanitary purposes is not the most economically effective solution at the moment. However the proposed design may become of interest and economically acceptable solution in case of the increasing prices of energy and/or natural resources.
