Real building-performance investigations, by discipline.
We don't simply publish case studies — we document real diagnostic investigations. Every one is built from a genuine completed project and its actual customer review, organised into the seven disciplines of our diagnostic workflow. Each library aligns with a Retrofit IQ Academy guide, so you can read the building science behind the work.
Seven investigation disciplines
Building Performance Investigation
A real, fully anonymised whole-house investigation of a large London property — blower door testing, smoke tracing, thermal imaging and a prioritised retrofit strategy.
Condensation & Mould Investigations
Diagnosing condensation, penetrating and rising damp by mechanism — not guesswork or a single meter reading.
Airtightness & Blower Door Investigations
ACH₅₀ and air-permeability testing, smoke tracing and air-barrier verification on real buildings.
Thermal Imaging Investigations
Thermal imaging surveys revealing missing insulation, thermal bridges and air-leakage paths on real buildings.
Ventilation & Indoor Air Quality Investigations
Ventilation strategies and indoor air quality improvements — from MVHR to humidity and pollutant control.
Retrofit & Insulation Investigations
Moisture-safe insulation and whole-house retrofit — internal, external, loft, roof and floor.
Soundproofing & Acoustic Investigations
Airborne and impact noise solutions — acoustic floors, decoupled walls and flanking control.
Passive House & EnerPHit Investigations
Whole-building performance to the Passive House and EnerPHit standard — modelled, built and verified.
Every investigation follows the same discipline: Investigate → Diagnose → Design → Remediate → Verify.
An investigation is not an inspection. We measure first — with calibrated thermal imaging, blower door testing, smoke tracing, humidity logging and moisture investigation — diagnose the root cause, design a targeted remedy, carry out the works and, where appropriate, verify the result against the measured baseline. Each investigation below records that process on a real London project.
