Application: Product Design & Marketing
• Early-stage: What is the value proposition in different regions?
• Mid-stage: How can performance be optimized?
• Late-state:Target marketing for customer segments with most to save Potential revenue from high-efficiency
variable-speed heat pump equipment salesand installation in households where theupgrade has a less than 5 year paybackperiod.
