Nanotech Materials for Truly Sustainable Construction
The time to start watching how companies are investing in and deploying nanotech won’t come in some distant future . . . that time is now!”
 First described 24 years ago
 Manipulating individual atoms
 Smaller than “micro”
- a nanometer is one billionth of a meter
 A revolution in building materials
 Important as part of 3BL
 The “sustainable buildings” initiative
 High “performance” workplaces
Three Questions:
 Do you assume “going green” adds to your first cost?
 Can you name 3 nanotech base building materials?
 How will nanotech enhance the building stock?
Five Segments
1. Context
2. The revolution in building materials
3. How to integrate nano-materials with business goals
• Case study #1: office work environment
4. Current “green” nano-material example: aerogel
• Case study #2: Base Building Design
5. Next steps, resources & contacts
CRE is a big target
 60% of global industrial waste is from the construction and demolition of buildings
 60% of electrical use in developed nations is by buildings
 40% of total energy consumed is by buildings
What is Nanotechnology?
What is it?

 Nano is Greek for “dwarf”
 Manipulation of matter < 100nm
 (1 10,000th the size of a bacterium)
 80,000X smaller than a human hair
 Revolution began 47 years ago
Why now? We can do it!
 Tools are available
 Global competition (Asia vs. Europe vs. North America)
 $10 billion global investment
 Real, useful products are already here
 Useful response to global climate change
Old or new? (Damascus 900-1750AD
Arms race? The first crusaders encountered better steel
 Wootz steel, developed in India & Sri Lanka ~300 BC
 greater strength & flexibility due to carbon nanotubes
 technique lost ~1750AD
Tipping point was 2000
R & D nano spending in 2004
2006: Seven Program Component Areas

1. Fundamental nano-scale phenomena & processes ($234 mil)
2. Nano-materials ($228 mil)
3. Nano-scale devices and systems ($244 mil)
4. Instrumentation research, metrology, and standards for nano-technology ($71 mil)
5. Nano-manufacturing ($47 mil)
6. Major research facilities & instrumentation acquisition ($148 mil)
7. Societal dimensions ($82 mil)
