For buildings for which a planning application was submitted to the relevant Planning authority after 01.01.2011, it is mandatory that hot water demand is partly covered by solar panels (min. percentage: 60% per annum). This requirement is waived where the hot water demand is covered by other energy supply systems based on RES, CHP, by district heating or heat pumps with a Seasonal Performance Factor (SPF) higher than (1.15 Χ 1/η), where η is the ratio of total gross electricity generation to primary energy consumption for the generation of electricity according to the European Directive 2009/28/ΕC and at least 3.3. (art. 4 par. 3 Law No. 3661/2008 and ΚΕΝΑΚ art. 8 par. 3.1.3). After 31.12.2019, all new buildings will have to cover their entire primary energy consumption using the aforementioned technologies (ΚΕΝΑΚ (art. 8 par. 3.1.f). In addition, all buildings should be almost zero energy buildings from 2021 onwards (art.9 Law No. 4122/2013). In September 2018, MEE published its “National Plan for the increase of Near Zero Energy Buildings (NZEB)” that was open for public consultation. The Plan includes the definition of NZEB along with the description of the current situation of buildings in Greece. Furthermore, policies and measures concerning the increase of NZEB’s percentage are also included.
