Royal Decree 732/2019 - Technical Building Code

The Technical Building Code (CTE) sets energy efficiency targets for buildings, which vary depending on the building's use and location. New residential buildings in warm climates must meet a max energy consumption limit of 30 kWh/m2 per year, while non-residential buildings must meet a limit of 50 kWh/m2 per year. It also includes requirements for space heating, space cooling, water heating, ventilation, humidity control and lighting, and a minimum contribution of thermal renewable energy sources.
