Agenda

Introduction to what Building Thermography is

Case studies on a range of applications

Benefits


What is Thermal Imaging All About?


Find damp+ trace leaks

Locate hidden “stuff”

Non-Contact

Monitor/ diagnose systems

Reduce energy £££ Improve

sustainability

Non-Destructive

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?

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

Thermal Conductivity


÷ 5-10

x 20-30

Damp buildings waste energy!!

Construction Materials

Water

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


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


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

Heat Loss Survey – Hall of Residence


So why are 50% of the windows

wide open?

Refurbished. Good stuff!!

Next up? Next up?

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
