Turning building performance data into better decisions
As regulations tighten, performance expectations rise, and net-zero targets become more demanding, understanding how a building actually performs has never been more important.
Whether we undertake the work directly or collaborate with one of our trusted specialist consultants, BTS provides independent, evidence-based advice grounded in real-world building performance data.
More than testing
Most testing providers deliver measurements and results. BTS Consultancy helps clients understand the story behind the data. Our team works with developers, contractors, housing providers, architects, consultants, and building owners to interpret performance data and provide practical recommendations that improve outcomes.
We help answer questions such as:
- Why is a building not achieving its expected energy performance?
- What is causing overheating complaints?
- Are airtightness results affecting operational efficiency?
- Is the building performing as designed?
- How can environmental conditions be improved for occupants?
- What evidence is needed to demonstrate compliance or performance targets?
By combining testing, analysis, and expert interpretation, we provide clarity where standard testing reports often stop.
