Invitation to TU Delft Research Exhibition Event: 11 November 2014Come to Delft University of Technology to explore our fields of research, which can be of great interest to your company. At TU Delft Research Exhibition Event 2014, more than 80 research projects will be presented. You can also attend a large selection of speed lectures

Admission to the event is free and it will take place in the Library, an iconic landmark on the TU Delft campus. Please register if you wish to attend.

Louis Kahn, famous American architect (1901-1974)

“I do not like ducts, I do not like pipes. I hate them

thoroughly, but because I hate them so thoroughly,

I feel that they have to be given their place. If I just

hated them and took no care, I think that they

would invade the building and completely destroy

it. I want to correct any notion you may have that I

am in love with that kind of things”

Gescheiden ontwikkeling Architectuur en Klimaattechniek

• < 1900 architect is integraal ontwerper• > 1900 ontwikkeling klimaattechniek als

zelfstandige discipline• Moeizame communicatie architect en ingenieur• Antibiose architectuur en klimaattechniek• Slechte gegevensuitwisseling • Gebouwkwaliteit niet optimaal• Faalkosten: raming >10% van de omzet

Synthese tussen Architectuur en Klimaattechniek mogelijk?

• Maak van het gebouw een “klimaatmachine”• Klimaattechniek met Architecturale middelen• Synthese van

– architecturale expressie en klimaattechniek– intuitieve creativiteit en rationele logica

• Architect mede verantwoordelijk voor– binnenmilieu– energiehuishouding
