Building performance simulation

• Is a powerful technology
• Is helpfull if building and systems are treated
  as a complete entity
• Undergoes a rapid change
• Is rarely used in early design phase

Conclusions up to now

• Connection works!
• The first simple calculations are possible
• Connection works for any 3D (IFC) design

Future work?

• Support consumers
• When should (Energy and Comfort) scores be
  available?
• Are the changes in the design actually noticeable
  in the scores?
• Advice possible without interaction between
  prototype and consumer?
• Support architects
• Call for intermediate testing?
• Are architects experienced enough to enrich the
  IFC model?
