CTE DB-HE 2019 (Building technical regulations / Energy savings) [Spain]
The CTE DB-HE regulates the energy use and demand of buildings, both for new construction and retrofitting. Recent updates to the DB-HE have introduced the requirement of building (or retrofitting old buildings to become) near-zero-energy buildings. All building projects approved after 28 June 2020 must follow the new regulations.
