Introduction
• June2, 2001
• -20% to - 40%, with summer comfort
• Performance-based approach
• Three requirements– Energy consumption < Reference– Summer temperature– Minimal performance of some components

Challenges
• Environmental– 1/4 of gas emissions– More and more severe every 5 years– To optimise products for retrofitting
• Social: cost mastering
• Economics : European standards

Tools
• Calculation softwares: ThC, ThE– “free” softwares– air conditioning: models to come by 2 years
• Technical solutions

Expected Changes
• Flexibility and optimistaion, but “garde-fous” such as minimum insulation
• Tertiary: tremoundous evolutions of technical solutions
• Thermal bridges: technical solutions to be proposed
• Air tightness: objective: strict application of execution rules

• Low emissivity glazings … argon
• Energy sources flexibility: flue tubes in electric houses
• Roof and wall higher insulation
• Hygro-variable ventilation in electric houses
• No “permanent flame” in gas boilers
• Lower thermal bridges in collective buildings
Expected Changes
