HIGH PERFORMANCE HOMES WHAT ABOUT THE COST

2

EVOLUTION OF HOMEBUILDINGNEW BECOMES NEW AGAIN...

3

CONSUMERS WANTS VS. WALLETS$30K EYES VS. 15K WALLET

4

CAN HOUSING ACCOMPLISH BOTH GOALS?

5

Traditional Approach

Non-cost/Savings items are valued at $0

Cost items are over-valued to cover unknowns

Result: Over-state costs that do not create value in the eyes of consumers

6

Proposed Approach

Determine true value of all improvement ideas regardless of how small the savings

Add affordable, correctly valued features (offset by your savings)

Result: Net-Zero cost sustainable homes
