Applying building science principles allows for the construction of energy efficient,durable healthy buildings
The house must be treated as a system to ensure expected performance
Airtightness in combination with a distributed ventilation system is critical for energy
efficiency, building durability and occupant comfort
A well insulated building envelope with an air barrier and correctly placed vaporbarrier reduces energy use, eliminates condensation and mold growth and providesa comfortable indoor environment
