SIMULATION MODEL IN TRNSYS OF A SOLAR HOUSE FROM BRAŞOV, ROMANIA

Abstract

Energy consumption in buildings is a large share of the world’s total end use of energy. Residential and commercial buildings require approximately 35% of the end use of energy, in addition to this energy is used for buildings also in the industry. In this context the paper proposes the energetically analysis for a small-scale modern station, providing solar heat to a solar house with 2 floors, located in the city of Braşov, România. The paper describes the location, size and thermal regime of the solar house; there are also presented the heating system facility and equipment components, designed for the solar house located in Transilvania University Campus. Based on the achieved simulations it is shown that compared to the ordinary control the energetically-based control provides remarkable advantages and savings concerning the auxiliary heating energy. This result should be valid for any systems similar to the particular one in Braşov.
