  • Requirements
    • Based on a "recharge the tanks" model
    • 50K BTU Heating / day = XX BTU per hour (using 24 hours)
    • 40K BTU Cooling (using off peak hours only = 12 hrs)
  • Design / Selection
    • Ideas
      • use the natural effects of the basement and earth tubes to gain higher performance from the heat pump
      • can we simplify the equipment (less is better)
    • Design
      • Air-to-Water Heat Pump
      • Earth Room
        • Location: Green Garage Basement
        • Supply: 2 6" earth tubes
        • Exhaust: existing chimney
        • Fan: Located in chimney...pulls air through the room
        • Thermal Mass: Plastic bottles full of water in room
        • Insulation
          • Walls: 30R West and South / Zero R North and East
          • Ceiling: 45R
          • Floor: Zero R
        • Raised Equipment Platform: use block
  • Rationale
    • zero-energy
    • simplicity
    • repeatability
