Chifley Passive House: A Case Study in Energy Efficiency and Comfort

The result was a house that required virtually no heating in winter despite frosty -2°C mornings; no artificial cooling in summer despite 37°C days and; overall consumed 64% less energy than similar households in the same city. Energy consumption, temperature and CO2 levels have been monitored and confirm exceptional levels of comfort and indoor air quality. The total energy consumed was within 12% of predicted values thus supporting the effectiveness of the Passive House Standard.
