Building performance measurement in practice: Luke Smith on Pulse, HTC and closing the performance gap

Building test solutions Luke Smith

Building performance measurement is not a buzzword; it’s how Luke Smith’s team turns claims into proof. From Pulse airtightness to Smart HTC, Luke shows how simple tests during build, and quick sign-off in occupied homes, close gaps, de-risk retrofit and help clients sleep at night.

 

What’s the big idea?

In Luke’s words: measure more, earlier. Building performance measurement gives developers, contractors and housing providers the same thing parents want from a nursery: confidence the environment really works.

“Only by measuring do you close that feedback loop… our mission is to make measurement mainstream.” — Luke Smith

 

Why this matters on live projects

Without building performance measurement, designs drift and fixes get hidden behind finishes. With it, teams catch leaks at first fix, right-size heat pumps, and present lenders with numbers that stand up to scrutiny.

Pulse vs blower-door: use them differently

 

Pulse is a seconds-long compliance check, ideal for occupied homes, while blower-door remains the gold-standard for leak hunting. Together, they make building performance measurement faster and more practical on site.

 

Whole-fabric truth with HTC

HTC testing wraps up air leakage, thermal bridges and U-values into one number. It anchors in outcomes clients can trust.

 

What trips teams up?

Treating testing as a tick-box at handover. Real building performance measurement happens at intermediate stages: window-fan checks after critical trades, plus a final sign-off that verifies the brochure claim.

 

Practical steps this month

  1. Add an interim airtightness check to your current site.

  2. Commission HTC on a finished block.

  3. Build a light plan into 2026 specs who tests, when, and what “pass” means.

How do I close the performance gap?

Run interim airtightness + HTC, record results, fix root causes before finishes. That’s quality control, not theatre.

 

What’s the quickest low-disruption test?

Pulse: charge, press, result in seconds. Fold it into your building performance measurement routine for occupied homes.

 

How do I use data with clients and funders?

Present clear before/after metrics from building performance measurement: airtightness, HTC and a short note on actions taken. Credibility beats slides.

 

Key takeaways

  • Make building performance measurement normal: test early, test often.

  • Use Pulse for fast sign-off; blower-door for diagnostics.

  • HTC gives the whole-fabric number clients understand.

 

Measurement-led delivery, collaboration and future-readiness. This is the kind of work we support at Darren Evans Ltd. If this resonates with your challenges, let’s talk.
