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.


The update and adaptation of the CTE  targets specifically the construction of new buildings, while paying less attention to the rehabilitation of existing buildings. Thus, the cases for rehabilitation should be clarified and related actions made more flexible.
