By incorporating 4KW PV Solar, Solar hot water, Passive Solar features drop expected sub- $90 monthly utility bills to very low levels:
- PV Solar = about $45 month harvested
- Solar = about $15 month savings
- Passive Solar reduces heating month’s loads by about $20 per month
- Passive Solar/north berming also reduce summer cooling loads
Low maintenance exterior & roof, low water use/rainwater harvesting, sustainable products, etc all utilized in base design (Good basis for a "Green Certification" program)
Expected heat pump size less than 1-1/2 tons (Easy to implement "mini-split" HVAC units)
