Passive House is today’s most rigorous building standard focusing on energy efficiency and occupant comfort. Passive House is a set of building science principles which can be applied to any building, by anyone, to achieve a result that vastly outperforms a similar building of typical construction.
Benefits of Passive House
There are many benefits to a passive house
1. Energy Efficiency – By applying passive house principles, these buildings use up to 90% less energy than it’s counterparts.
2. Superior Comfort – Passive house means a house with no drafts, no temperature variations, and really quiet. Another benefit is the resilience of the structure in times of power outages. The structure can naturally maintain a comfortable temperature for long periods of time.
3. Superior Indoor Air Quality – Having an air tight enclosure along with balanced continuous ventilation results in indoor air quality which can’t be matched by a typical house.
4. Building Durability – Applying passive house building science principles results in a house that is properly balanced, resulting in a reduction in moisture and mold risks, extending the life of the structure. There is an added benefit of less required building maintenance.
5. Cost Savings – An initial cost savings on mechanical equipment and long term savings on the energy costs. In addition, since passive houses use so little energy there is assurance that future energy price increases will have marginal effect.
6. Sustainable choice – As a result of the energy savings, passive homes have a significantly reduced carbon footprint over the life cycle of the home.
Principles of Passive House Design
The diagram below illustrates the main principles of passive house design. Which are:
1. Solar Orientation
2. High Insulation
3. Air Tight Enclosure
4. High Performance Windows and Doors
5. Balanced Ventilation with Energy Recovery
