•
The Product: Dissecting the Home Purchase
•
The Context: Energy Star in a ‘Green’ World
•
The Industry: The New Normal
•
The Business Case: Addressing New Normal
•
The Metrics: Why Energy Star = Good Policy
THE PRODUCT
DISSECTING THE HOME PURCHASE
•
Home = Lifestyle Liability•
Building Science = Investment + Performance
•
Renewable Power = Investment + BOH
