The high-quality materials used for construction, the tightness, the thermal insulation, and the heat recovery ventilation system of the energy-efficient houses generate an energy consumption up to 90% lower than in the case of conventional houses.
The largest annual energy bill for an energy-efficient house in Romania, which has not reached the €2000 threshold, was recorded in 2015, for a house built in Cluj-Napoca.
The construction of the energy-efficient house using high-quality materials and technologies reduces heat loss completely, which is why the temperature is preserved constant for a longer time, with little extra heating needed. The very low energy consumption is one good reason to choose an energy-efficient house at the expense of a conventional one.
