The energy performance certificate is mandatory for all new buildings, being valid for 10 years since their release, and energy-efficient houses get a very good energy score and become more desirable on the real estate market.
One of the main means of demonstrating the energy efficiency of a building is its energy certification - a process that is, in fact, mandatory for all buildings, whether they are old or new. The certification is based on the annual energy consumption and carbon dioxide emissions, as well as the condition of the installations, walls, roof etc.
At the time of certification, the energy-efficient house receives a high energy score, being rated as energy-efficient, and this, among others, makes it more desirable in case of a possible future sale.
