It's the worst feeling to be uncomfortable because of a leaky, drafty building. And it's no fun being sick because of poor indoor air quality due to dust and mold.

What makes for a healthy and comfortable building?

• Comfortable temperature is 21 degrees Celsius / 70 degrees Fahrenheit, with approx. 50% relative humidity.
• Your head and feet feel the same temperature within about 5 degrees.
• You have 30 m³ of fresh air every hour per person - or about 18 ft³ per minute (cfm) per person.
• Ventilation is constant in all living and working spaces, including exhaust spaces like bathrooms and kitchens.
• Super insulated, air tight structures with excellent windows and doors require less energy to heat and cool, and stay at a more consistent temperature.
