Türkiye: The Turkish government has introduced new rules on the minimum thickness of insulation used in urban construction. Buildings in Ankara must be fitted with 9cm-thick insulation, compared to 6cm previously, while those in Istanbul must be fitted with 8cm-thick insulation, compared to 5cm previously. Suar Energy News has reported that this accompanies new government regulations that require all new builds to source at least 5% of their electricity renewably, as part of a drive for Nearly Zero-Energy Buildings (NZEB).
