Not even close to Passive House standard. Air sealed to 0.85 ACH50, compared to Passive House standard of 0.5 ACH50. Walls are R32, ceiling R96, windows Anderson 400 series, 4" foam under crawlspace and under footings, 1300 square feet.
Heat is from a Triangle Tube Prestige Solo 60 with three zones: House heat, domestic hot water, and shop heat.
Calculated heat loss is 11,000 BTUH house plus 2,000 BTUH ventilation air at 90 deg F temperature difference. I originally wanted better insulation and windows to get that down to 9,000 BTUH for the house, but $12,000 extra to save $50 per year on the heating was too much.
