Bridgnorth Police Station — Thermographic Survey

The Project

A police station is a building that can’t simply be emptied for a survey — it operates around the clock, and any assessment has to work around the people using it. This survey, in Bridgnorth, Shropshire, also makes a point we’re often asked about: we’re based in Glasgow, and we work wherever the job is.

What We Did

We surveyed the building inside and out using two complementary thermal methods:

• Internal handheld thermography — room by room with a FLIR thermal camera, mapping heat distribution across walls, windows, and heating elements from the occupied side of the fabric.
• Drone thermography — radiometric thermal capture of the roof and elevations from the air, revealing the envelope’s heat-loss pattern at whole-building scale: the aerial imagery shows the windows glowing as the dominant loss paths against the cooler masonry.

Working internally and externally on the same visit is the fastest way to separate real fabric defects from surface effects — what looks like a cold bridge from inside can be confirmed (or dismissed) from the outside image of the same element.

The Deliverables

• Internal thermographic imagery, room by room
• Aerial radiometric thermal imagery of the roof and elevations
• A whole-building picture of where the envelope is losing heat

For estates teams managing public buildings, this is the evidence layer that turns “we should improve energy efficiency” into a prioritised list of which elements, on which elevations, are actually leaking heat.
