Final Project

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

Introduction Methodology Results Conclusions Discussion

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?
