Building Performance Diagnostics in South Bank

The South Bank is a cultural riverside quarter dominated by modern, highly-glazed apartment buildings served by mechanical ventilation. Our work here is consultancy and verification — overheating, indoor air quality, ventilation commissioning and acoustics.

One company, the whole process

Investigation only, remedial works, or a complete retrofit — your choice.

RetrofitIQ is not only a diagnostics company. We take projects from first investigation through to verified improvement — and you decide how far we go. Engage us for an investigation on its own, for an investigation plus targeted remedial works, or for a complete building-performance and retrofit project in South Bank.

  • General building-fabric improvements
Local building stock · South Bank

The buildings of South Bank, and how they perform.

South Bank residential stock is largely new and recent high-rise apartments with sealed façades, large solar-exposed glazing and per-flat or centralised mechanical ventilation. Comfort complaints centre on heat gain, ventilation performance and noise rather than draughts.

Typical properties in South Bank
  • New-build riverside apartments
  • Highly-glazed residential towers
  • Mechanically-ventilated (MVHR) flats
  • Mixed-use cultural-quarter buildings
  • Serviced and rented apartments

Thermal Imaging Surveys in South Bank

On the South Bank, thermal imaging verifies slab-edge and frame thermal bridges and façade performance.

  • Mapping heat loss through walls, roofs and floors
  • Locating missing, slumped or incomplete insulation
  • Identifying thermal bridging and cold spots
  • Highlighting surfaces at risk of condensation
  • Revealing hidden defects behind finishes

Damp, Condensation & Mould Investigations in South Bank

Condensation here is localised to cold bridges or under-ventilated rooms; we measure to pinpoint it.

  • Separating condensation from penetrating and rising damp
  • Finding mould behind wardrobes, furniture and in cold corners
  • Measuring relative humidity, surface temperature and dew point
  • Assessing ventilation provision and moisture sources
  • Combining thermal imaging with a building-physics review

Heat Loss & Energy Efficiency Surveys in South Bank

Priorities are solar-gain control and ventilation heat recovery, not solid-wall loss.

  • Pinpointing where heat escapes — walls, floors, roofs, windows and doors
  • Setting fabric-first retrofit priorities in the right order
  • Quantifying the impact of each potential improvement
  • Assessing heat pump readiness where relevant
  • Producing a clear, costed improvement plan

Blower Door Testing & Airtightness in South Bank

These buildings are tight — our focus is ventilation commissioning, airflow and indoor air quality.

  • Measuring air leakage and uncontrolled heat loss (ACH₅₀)
  • Locating draughts with smoke tracing
  • Identifying leakage paths through floors, lofts and services
  • Guiding targeted airtightness improvements
  • Verifying performance before and after retrofit works

Retrofit & Building Physics Advice

We specify and oversee ventilation re-commissioning, filtration, solar-control and acoustic upgrades, then verify.

  • A fabric-first, Passive House-informed approach
  • Retrofit advice aligned with PAS 2035 principles
  • Internal and external wall insulation risk assessment
  • Thermal-bridge reduction and condensation-risk modelling
  • A coherent ventilation strategy to protect health and fabric
What we see locally

Common building performance problems in South Bank.

Apartments overheating behind large riverside glazing
MVHR systems never commissioned, balanced or maintained
Stuffy, high-CO₂ bedrooms despite a mechanical system
Condensation at cold slab-edge and frame thermal bridges
Noise transfer between apartments and from plant
Poor filtration and indoor air quality near busy roads
Limited occupant control of temperature and fresh air
