What is a Thermal Image?
Radiated infrared energy (not temperature!)
Detected by camera at the target’s surface
Different colour schemes or “palettes” are used to show the amount of energy detected

What do the colours mean?

But take care!

Why Use Thermal Imaging?
Thermal imaging of buildings is used for many reasons including VISUALISING & DIAGNOSING:
1. HEAT FLOW
2. MOISTURE
3. STRUCTURE and sub-surface components/ systems
4. MECHANICAL AND ELECTRICAL systems

Goals of Scanning Building Fabric
Typically – to assess:
Continuity of insulation
Absence of thermal bridges
Absence of excessive air leakage
But also:
Absence of excess moisture a.k.a “damp”
Usage and Behaviour

Damp buildings waste energy!!

Simplistically...
Heat flow through fabric is a function of conductivity of
structural materials
W/m.k
Goals of Scanning Building Systems
Systems include:
Electrical
Mechanical
Plumbing
Heating and air conditioning
Solar
To assess:
Location
Condition
Performance

The Life of a Building
March 15 2016 © ScanTherm 2016 Page 11
Use
Maintain
Refurb
Design
Build Reality 1 Reality 2
Reality 3
Reality 4
Thermal imaging helps
get to the current reality irrespective of
how the building was
designed, built, intended to be
used and maintained
From Small: Individual Residences…

Heat Loss Survey – Hall of Residence
March 15 2016 © ScanTherm 2016 Page 25
Question: When is this type of survey conducted?
Answer: During heating season... before dawn
Very specifically:
Nov 26th 05.45 hours External temp: 4˚C

Thermography Benefits
Save Energy!
Improve Quality Visualise the invisible
Move from “as designed” to “as built” to “as used” and “as maintained”
Save Money Less destructive work, early detection, less access equipment
Communicate Very visual medium
Change behaviour!!
Improve Sustainability Verify thermal performance, BREEAM
