Definition of a passive design
Energy efficient house
The idea of a passive house is to maximize comfort in the house. Natural light/resources should also be taken into consideration and used as much as possible in the house.
The concept of a passive house is to minimize heat loss and maximize heat gain.

Mechanical Ventilation Heat Recovery
fresh air around your house
take in fresh air from the outside
wet rooms - utility rooms, bathrooms, kitchen
Dry rooms - Bedroom, hallway
Heat exchange
Fresh air from the outside turns into warm air on the inside
Outside cold air goes into the heat exchanger and this will leave a warm supply of fresh air inside the house
