Thermal regulations (réglementation thermique, RT)
Thermal regulations set a maximum limit on the energy consumption of new buildings. After versions in 2000 and 2005, the current regulations date from 2012 (RT 2012). They apply to new residential and non-residential buildings and cover energy consumption for heating, domestic hot water, lighting, air-conditioning, ventilation and auxiliary equipment. The requirements correspond to those of BBC-effinergie® certification. For residential properties, for example, maximum energy consumption is 50 kWhpe/m²/year.
