TRADITIONAL NEW CONSTRUCTION vs PASSIVHAUS

The construction of a traditional new construction and a Passivhaus have significant differences in terms of design and energy efficiency. Here are some key comparisons:

Design: In a traditional new construction, the design is based on conventional construction practices and standards. A Passivhaus, on the other hand, relies on specific design principles to maximize energy efficiency and interior comfort. This involves proper orientation, superior thermal insulation, an airtight envelope and controlled ventilation.

Durability: Passive houses are built with high-quality materials and advanced construction techniques, making them more durable and resistant to the passage of time. This can result in lower maintenance and repair costs in the long run.

Energy Efficiency: The main difference between a traditional new construction and a Passivhaus lies in energy efficiency. A Passivhaus is designed to minimize energy loss and maximize solar heat harvesting, resulting in significantly lower energy consumption compared to a traditional construction. This is achieved through high-quality thermal insulation, triple-glazed windows, an airtight envelope and a controlled ventilation system.

Interior comfort: A Passivhaus offers a high level of interior comfort all year round. The interior temperature remains constant and comfortable without the need for conventional heating or cooling systems. This is achieved through careful design that maximizes solar heat harvesting and minimizes heat losses. In addition, the indoor air quality is better due to the controlled ventilation system that filters and purifies the air. This is especially beneficial for people with allergies or respiratory sensitivities.

Costs: The main material used inside the walls is wood, a relatively much more expensive material than concrete, but where the prices are compensated is in the fast delivery times of the house. In the traditional system you are paying for labor, in the passivhaus system you are paying for high quality materials.

Sustainability: The construction of passive houses has a lower environmental impact compared to traditional construction. By reducing energy consumption, greenhouse gas emissions are reduced and the fight against climate change is contributed.

In short, a Passivhaus offers greater energy efficiency, interior comfort and sustainability compared to a traditional new build.
