The Bylaw on Energy Efficiency applies both to the new buildings and reconstruction, upgrading, renovation, remodeling, reparation and energy recovery of existing buildings.
However, when it comes to ensuring the efficient use of energy in buildings, different factors are taken into account. These factors include: the lifetime of the building; climate location; position and orientation of the building; its purpose; the conditions of comfort; materials and elements of the building structure and envelope; technical systems and embedded devices; energy sources and cogeneration; and the ability to use renewable energy sources. Therefore old and the new buildings are not expected to be treated in the same way.
Furthermore, the Bylaw on Energy Efficiency excludes certain types of buildings from the scope of its application. Excluded buildings include: buildings that do not require a building permit; buildings that are being built with temporary building permits; buildings that are built based on the building permit for preparatory works, such as workshops, manufacturing halls, industrial buildings that are not heated or air conditioned; and buildings that are occasionally used during the winter and summer season (less than 25% of the time duration of the winter or summer season).
