Beast From The East
As the Uk population cabined up to hibernate away from the beast from the east DJM Aerial Solutions decided the best cause of action would be to carry out some infrared inspection or thermal survey.
Aerial Thermal Survey
As the cold snap set in prior to the arrival of snow DJM Aerial Solutions decided to utilise the cold weather to carry out a building envelope inspection via an aerial thermal survey ( infrared inspection ) around several properties requiring it. The sub-zero temperatures laid out idealistic conditions to produce the relevant heat signatures and data from the building envelope.
Building Envelope Survey
We mounted the Zenmuse XT radiometric infrared inspection sensor to our flagship RPAS the Matrice M210 and began the survey. Ideally, an observer is required during any aerial thermography inspection due to the sheer amount of time required staring at the screen to analyze the acquired data.
Primary Thermal Energy Loss
During both Thermography inspection routines, we came across several energy losses from around the openings of the building and roof area. Both very different. The first one that is indicated in the below video displays signs of energy loss, from the edges of each window and the below windowsill. Basically indicating that the heat from the house is leaking through the window edges.
Secondary Thermal Energy Loss
On the next inspection, we did, in fact, detect that the window seals were defective and the inert atmosphere that is provided by the window manufacturer is no longer evident. This gas which is generally Argon due to its inert properties (none reactive) with any other gas or material. It prevents condensation between the pains and possible chemical reaction between any steelwork and the external oxygen. But also provides a second layer of insulation.
The heat signature detected from these windows displayed a higher temperature than any other of the outside surfaces and is common across the whole pain of glass it is not unusual for the window to contain other panels of glass that are in good condition. These can obviously be used as a reference point.
Radiometric Infrared Inspection Sensor
The radiometric infrared inspection sensor provided us with the thermal data required to analyze each individual pixel if required, this gives us an accurate definition of thermal energy loss and provides the correct data calculate the exact temperature differential across two areas. This option is essential when following up with a detailed reporting schedule post thermography inspection.
Roof Asset Condition Survey
Obviously, most of the energy loss from an energy inefficient home would tend to stem from the roof and soffit area especially in older buildings where there is minimal insulation installed. It is essential to try and eradicate this by installing insulation of some sort preventing further energy losses resulting in a more energy efficient home and reducing the financial implications associated with it.
