• Everyone has a role
• Highest Utility Cost• Optimization – Focus is on Reducing Waste• Impact on Environment• Impact on Indoor Environmental Quality
ChallengesChallenges• Limited Information • No Visibility or Accountability for Energy
Use• Not Understanding the Urgency• Perceived Insignificance of the Individual• Conservation Myths • Stereotypes• Abstract Concept
