The Coca-Cola Company recently announced that it would work with Georgia Tech's Enterprise Innovation Institute to reduce energy consumption at its headquarters in Atlanta, Georgia. The budget is $3 million, which will include the installation of energy-efficient lighting and HVAC equipment, irrigation controls and rainwater harvesting. Coke is anticipating the retrofit will take about 12 to 18 months...helping them to eliminate 10,000 metric tons of carbon dioxide emissions annually and $1 million in operating costs. I am a little miffed though...for a Fortune 500 company with over $5 billion in net income and over $29 billion in assets, if you are going to green your headquarters, I would think that Coca-Cola would not just do a $3 million retrofit (.00059% of net income) but that they would build a state of the art, energy-efficient, sustainable 8th wonder of the world (Coke Annual Report)! But props to Coke for making the commitment to sustainability by upgrading their facilities and contributing to an improved environment! The cool thing about green retrofits is that once the improvements have been made, you have a two points of reference for comparison...the pre- and post-green retrofit, which is great imperical evidence to analyze the value and efficiencies of installing green upgrades.
