Thermographic Survey in UAE

Thermographics can play a vital role in driving build quality and improving thermal performance.

A thermographic survey can help us to identify hidden problems during and after construction, and also demonstrate performance against environmental standards.

Thermographic Survey

Building envelope leaks, poor or inadequate insulation, facade integrity assessments, moisture and substandard work are costly to commercial and residential building owners- a thermographic building fabric survey can quickly help you find where energy efficiency can be improved.

What is Thermography?

Thermography is a non-invasive diagnostic method, based on object surface temperature detection. The infrared (IR) radiation emitted from an object is recorded and visualized in the form of a temperature distribution map. The resulting image, known as a “thermogram”, can be used to determine; structural defects, electrical faults, mechanical faults, physiological changes in people & animals, and much more.

Thermographic Surveys are carried out by qualified engineers and are essential to the maintenance of fabric and electrical installations. These surveys are required to ensure that systems are working with no problems.

A thermographic survey inspects electrical equipment including distribution fuse boards, MCB boards, contactors, switchboards, transformers, motors, battery banks, UPS’s, control panels, switch fuses and isolators, etc whilst the equipment is in operation, causing no disruption to business operations.

Building inspections using thermal imaging

Inspecting buildings using a thermal imaging camera is a powerful and non-invasive means of monitoring and diagnosing the condition of buildings. Thermal imaging technology is one of the most valuable diagnostics tools for building inspections. Using thermal imagery, we can identify problems early, allowing them to be documented and corrected before becoming more serious and more costly to repair.  A building diagnostics inspection with a thermal camera can help:

Electrical Surveys

Electrical surveys can identify poor connections, overloaded circuits, failing components or imbalanced loads. Any faults on electrical systems are expensive in terms of plant downtime, damage, loss of production or risk from fire.

Building Heat Loss Surveys

We often conduct heat loss surveys for private clients who find that their heating costs have soared or who have a particular concern with a room, extension or the whole house. We can carry out a survey on your home or property and produce a report which will clearly identify heat loss or energy wastage. Very often the problems are not what the home owner thought they would be.

Missing or Ineffective Insulation

Missing or inadequate home insulation can literally cost you hundreds each year in additional power usage. By inspecting your property through the eyes of a thermal imaging camera, we are able to easily locate building defects and areas where insulation is defective or not even there at all.

The benefits of thermographic surveying

Thermal Imaging Surveys are generally carried out early morning or later in the evening and the heating should be left on 24 hours prior to the survey. This is to ensure any solar loading are eliminated or minimized to ensure a that there is a temperature difference of at least 10°C between inside and outside areas.

Thermography in buildings

A thermographic survey is non-destructive, so we can use it to assess build quality in terms of thermal bridging, continuity of insulation, air leakage, faulty glazing, and evidence of moisture or water leaks to name but a few, all without any intrusive work.

It is a common client requirement that construction work is checked for continuity of insulation using a thermographic survey, as well as often being part of BREEAM certification.

It can also be used as a diagnostic tool for problems with buildings, such as identifying sources of roof-leaks in complex designs, checking under-floor heating, finding air leakage paths for air permeability testing, or to confirm building energy performance after a change in design or building materials.

Getting the best results from a thermographic survey

For surveys of buildings, the number one requirement is a temperature differential between the internal and external of at least 10°C across the entire envelope.

As such, most thermal surveys need to be conducted several hours after sunset, in buildings that are complete and have a heating system in operation to create the 10°C temperature differential. A survey of a large and complex building may take more than one night, but 99% of the time, they are done within 4 hours.

Thermographic surveys for BREEAM

BREEAM is a globally recognised environmental rating scheme, and credits can be scored for carrying out a thermographic survey. To achieve the credit, the 10°C minimum temperature differential is a necessity, as is the wind speed (which must be below 5m/s) and there must be no precipitation. External surveys are also best done when there is cloud-cover.

As such, the weather forecast has to be closely monitored in the lead up to the survey so as to get the best chance of compliance. If the weather forecast changes on the day to show worsening conditions (higher wind speeds etc), then it is in our interest to delay the survey, even if it is just by a few hours.

As these requirements can give a very small window of opportunity, an internal survey is often preferential to eliminate some of the weather influences.

Temperature differential is key

The temperature difference of 10°C does need to be in place for a minimum of 10 hours. However, due to some buildings having elements

with a high thermal mass, such as a floor slab, this may take several days to heat up to the required temperature, which could lead to the thermal appearance appearing worse than it actually is. To that end, the heating may need to be on at the required temperature for as much as 5 full days prior to survey.

In the lead up to the thermographic survey, be aware that every area of the building to be surveyed requires the 10°C differential, so check each room to ensure that the heating system is working and hasn’t been turned off by site personnel. If an area of the building is not heating up as required, extra electric heaters may need to be temporarily used to meet the requirements.

Brief all site users of the heating requirements to limit the chances of heating being turned down, and windows and doors being left open. If a door is constantly open hours before a survey, this could give false temperature readings and be misinterpreted as a fault with the construction.

Other Use

Thermographics have an incredibly broad range of uses, from medical diagnosis to military applications. One use closer to home is that of electrical fault finding and diagnostics. For example we can use thermographics to survey photovoltaic arrays to find panels which may be faulty or under performing.
