**Notes:**
Stacked records CO2 (blue) with the temperature proxy (white) from the European Project for Ice Coring in Antarctica (EPICA) ice core from Dome Concordia (Antarctica) covering the last 650,000 years. CO2 is determined on bubbles enclosed in the ice. CO2 data from 0 to 420,000 years are from earlier measurements from ice cores from Vostok station [Petit et al., 1999], and Taylor Dome [Indermühle et al., 2000]. The isotopic records indicate the sequence of 6 full glacial cycles [EPICA Community Members, 2004]. New CO2 data measured at the University of Bern are from ice older than 420,000 years and extend the legendary Vostok record by more than 50% back in time. These data confirm that the present CO2 concentrations in the atmosphere are unprecedented for at least the last 650,000 years. The dashed line indicates the preindustrial CO2 concentration. The new data are part of two papers submitted to Science [Siegenthaler et al., 2005; Spahni et al., 2005].

## The relationship of buildings to climate change

**Notes:**
We are affecting the earth
And we can fix the damage we’ve done
• The ozone hole is getting smaller
• Conservation efforts are bringing some species back from the brink of extinction
• Recycling diverted 68 million tons of materials from landfills and incinerators in 2001 (source, US EPA)

## We have many inefficient existing buildings and many more to be built
Each year we build 5 billion sq. ft. new
We renovate 1.75 bill sq. ft.
By the year 2038, 3⁄4 of our buildings will be new or renovated.

If we accept that global warming is real and that we’re causing it, isn’t this problem so big that we can’t possibly fix it?

## The importance of transportation energy

**For the average US office building, commuting by workers accounts for 30% more energy than the building itself uses.**

## Certifying Green Buildings

**LEED is a program of USGBC:**
** **A** **non-profit organization committed to         expanding sustainable building practices.
-  Composed of more than 13,500 organizations from across the building industry

**Overview of LEED**

**Notes:**
USGBC is working to promote buildings that are environmentally responsible, economically profitable, healthy and productive places to live and work and provide a consistent benchmark to rate green buildings and interiors

## Why do we need LEED?

- Recognition of Quality Buildings and Environmental Stewardship
- Third party validation of achievement
- Qualify for growing array of state and local government incentives
- Contribute to growing knowledge base
- Receive marketing exposure through USGBC Web site, case studies, media announcements

- Johnson Control’s Brengel Technology Center, downtown Milwaukee
