In the ever-evolving landscape of construction, the pursuit of energy-efficient homes encounters a common obstacle: airtightness testing, particularly when traditional methods result in failures. This article explores how Coltraco Ultrasonics’ Portascanner™ is a game-changer, significantly reducing downtime by enabling swift identification and sealing of air leaks during the build program without the need for deconstruction.

Crafting energy-efficient homes demands meticulous attention to airtightness. Traditional methods, including certified door fan blower tests, can only be done after the build is complete. When airtightness test fails, it triggers the prospect of extensive deconstruction. This not only consumes valuable time but also introduces complexities in reassembly, impacting construction timelines and budgets.


Portascanner™: Streamlining Airtightness Testing

Portascanner™, driven by ultrasound technology, revolutionises the approach to airtightness testing.

  • Non-invasive nature = continuous testing throughout the build program
  • Eliminates the need for disruptive deconstruction
  • Ensures the construction process remains agile and efficient
  • Assures that the structure being fitted is fitted correctly without any air leaks.
  • Enables Real-time detection without dismantling structures.


  • Microscopic accuracy pinpoints leaks as small as 0.06mm
  • Address leaks immediately
  • Reduces the risk of failures during mandatory pressure tests
  • Eliminates the need for time-consuming deconstruction.


It’s swift and precise identification of air leaks streamlines the construction process, saving both time and labor costs.

How the Portascanner™ Impacts Passive House Standard

The Passive House Standard transforms sustainable building, seamlessly aligning with the goal of constructing energy-efficient homes. From design to certification, it ensures structures surpass expected performance levels.

For New Build Passive House Certification, stringent criteria include maintaining an annual heating/cooling demand of 15KWh/m² or a peak load of 10W/m². Essential to this is the air pressure test, where Coltraco Ultrasonics’ Portascanner™ ensures a first-time pass, mitigating risks of disruptive deconstruction.

In broader discussions on energy-efficient homes, the Passive House Standard, fortified by Portascanner™, exemplifies a holistic approach to creating sustainable living spaces that prioritize both efficiency and environmental stewardship. In essence, it sets a paradigm for a greener and more efficient future in construction.

Global Impact on Construction Efficiency

As the global construction industry pivots towards energy efficiency and sustainability, Portascanner™ presents itself as a catalyst for change. By minimizing downtime and wastage associated with deconstruction, it enhances construction efficiency on a global scale. This not only aligns with industry standards but also contributes to meeting net-zero energy consumption goals and promotes more sustainable construction practices.

Builders and developers seeking to streamline construction processes can immediately benefit from Portascanner™. Its ability to “test as you build” ensures a proactive approach to airtightness, reducing the fear of potential failures during future blower door fan tests. This proactive quality control aligns with the industry’s broader goals of sustainability and efficiency, without the need for subsequent deconstruction.



Portascanner™ emerges as a beacon of efficiency in energy-efficient construction, reshaping how airtightness testing is approached. By eliminating the need for deconstruction, even in cases of traditional testing failures, it not only saves time but also provides a cost-effective solution. As the construction sector embraces innovations that enhance sustainability and reduce downtime, Portascanner™ sets a new standard for agile, efficient, and environmentally responsible construction practices. In a future where every minute counts, this technology stands as a testament to the industry’s commitment to building smarter and greener.
