Autor/autori: Cristina TANASA, Valeriu STOIAN, Daniel DAN, Iosif BOROS, Cristian SABAU

Rezumat: Aceasta lucrare prezinta probleme specifice si aspecte legate de cost ale unei case pasive in sectorul constructiilor din Romania. Eficienta energetica obtinuta prin performanta energetica a cladirilor este un domeniu relativ nou in Romania, majoritatea oamenilor fiind sceptici in abordarea unor astfel de cladiri din cauza investitiei initiale ridicate. In apropierea orasului Timisoara a fost construita o casa conform standardului european de casa pasiva. Pe langa evaluarea teoretica a consumului de energie, casa e monitorizata in mod continuu in vederea obtinerii unor masuratori reale ale consumurilor. Pentru a pune in evidenta principalele avantaje ale casei pasive, aceeasi cladire rezidentiala a fost proiectata ca fiind o casa traditionala. In continuare a fost facut un studiu teoretic comparativ intre casa pasiva si casa traditionala. Principalul obiectiv al acestei lucrari este de a evidentia ca avantajele investitiei intr-o casa pasiva in ciuda investitiei initiale mai ridicate.

Abstract: This paper presents the specific impact and construction costs of a passive house in the Romanian building sector. Energy efficiency achieved through energy performance of the buildings is a relatively new field in Romania and most people are skeptical in approaching it because of the higher initial investment. In the city of Timi?oara, a residential house was designed and built as passive house complying with the European passive house standard. Besides the theoretical evaluation of the energy consumption, the house is continuously monitored in order to obtain real measurements of the energy consumption. In order to enhance the main advantages of the passive house, the same residential house was designed as a traditional house. Further, a comparative study was made between the passive and the traditional house. The main purpose of this paper is to enlighten that investing in a passive house brings great economical and comfort advantage despite the higher initial investment.
