Why Passivhaus is gaining real traction in construction in 2026

John Joe Roberts, Pre-Start / Pre-Construction Manager & Commissioning, Link365

Sustainability is no longer a future ambition for the construction sector — it is a present-day requirement. As regulatory pressure increases and clients demand measurable energy performance, Passivhaus is moving from a specialist standard into mainstream project conversations.

From my role at Link365, it is clear that the industry is beginning to understand that delivering genuinely low-energy buildings requires more than good intentions. It requires disciplined planning, strong coordination, and a performance-led mindset from the outset.

Early decisions are driving better outcomes

One of the biggest shifts we are seeing is the growing importance of early-stage involvement. Projects targeting high energy performance cannot afford late design changes or fragmented decision-making.

Passivhaus in particular places emphasis on:

• Careful detailing
• Continuous airtightness strategy
• High-quality installation
• Verified commissioning

When these elements are considered early in pre-construction, projects tend to run more smoothly and achieve their performance targets with fewer costly corrections later.

The expanding role of pre-construction teams

Pre-construction teams are now playing a more strategic role than ever before. Rather than simply reviewing drawings, teams must actively interrogate buildability, sequencing, and risk.

Key focus areas typically include:

• Thermal bridge reviews
• Interface coordination
• Services integration
• Programme alignment

At Link365, we are seeing that projects benefit significantly when these reviews happen early and collaboratively. It reduces uncertainty on site and supports a more predictable delivery phase.

Commissioning: the final piece of the puzzle

Even the best-designed low-energy building can fall short if systems are not properly commissioned. As buildings become more technically sophisticated, commissioning is moving from a box-ticking exercise to a critical performance function.

Mechanical ventilation systems, controls, and airtightness all require careful validation. The margin for error is much smaller than in traditional builds.

This is why commissioning strategies must be clearly defined during pre-construction — not left until the final weeks of the programme.

Skills and supply chain readiness

While momentum is building, capability across the industry is still uneven. Some teams are highly experienced in delivering low-energy buildings, while others are still on the learning curve.

To support wider adoption, the sector will need continued focus on:

• Workforce training
• Supply chain engagement
• Clear quality standards
• Better knowledge sharing

Encouragingly, we are seeing more clients prioritise long-term building performance over short-term cost savings, which is helping to drive positive change.

Looking ahead

As we move further into 2026, the direction of travel is clear. Energy performance, carbon reduction, and measurable building outcomes will continue to shape procurement and delivery models.

For contractors and project teams, the message is straightforward: high-performance construction is becoming the norm, not the exception.

At Link365, we believe those who invest early in process, people, and performance verification will be best placed to meet the industry’s next phase of demand.
