Introduction

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

3
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

4
Tools

• Calculation softwares ThC, ThE
• free softwares
• air conditioning models to come by 2 years
• Technical solutions

5
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

Expected Changes

• 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
