Building analysis and energy consultation


Building thermography can help you to analyse building shells in terms of their energy efficiency:

  • Energy losses due to poor or faulty insulation can be visualised easily
  • The whole building shell can be inspected quickly and easily using Testo thermal imagers.

You can therefore use building thermography to carry out professional energy consultation.

Building shell analysis for energy consultation

In building thermography, thermal imagers are ideal for quick, easy visualisation of energy losses in the heating or air conditioning systems of buildings.

Thanks to their high temperature resolution, Testo thermal imagers provide a detailed presentation of inadequate insulation and thermal bridges in the building shell. They are ideal for recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof structures or the entire building shell. Comprehensive diagnostic and maintenance activities can therefore be carried out in order to analyse energy efficiency, and structural improvement measures can be initiated.

Detailed energy consultancy, where the whole building shell is analysed for its energy loss, effectively indicates further possibilities for energy saving.

Testing the quality of construction measures

Ensure construction quality

Building thermography can help you to uncover structural defects quickly and efficiently and ensure construction quality. You can use thermal images to detect faults at an early stage and continuously monitor the construction quality.

Testo thermal imagers are ideal for providing proof of the quality of construction measures. Building thermography also facilitates the quick and easy localisation of thermal bridges, possibly caused by faulty thermal insulation. Any moisture and leaks that occur in buildings are also visible in photos taken by thermal imagers. Mould formation can therefore also be effectively prevented.

Detecting cold bridges

Thermal bridges are parts of the building construction through which heat escapes outside faster than it does in adjacent areas. The temperature is lower in the affected areas within the building. This can result in higher energy consumption and increased humidity.

Thermal bridges can be localised using a thermal imager. The thermal image displayed clearly shows that the temperature is lower in the corner of the room. Building thermography makes thermal bridges visible quickly, enabling measures such as insulation to be purposefully initiated at an early stage.

Identify leaks at windows and doors

If doors or windows are not correctly fitted, in winter cold air can enter and warm indoor air can escape. This results in draughts, increased ventilation heat loss and above all high energy costs.

You can use Testo thermal imagers to locate leaky windows or inadequate insulation, for instance on roller blind casings. In order to achieve optimum energy use, the building shell is analysed and any weak spots can be dealt with in the next step.

Detect areas at risk of mould

Construction faults or incorrect ventilation behaviour allow increased humidity to form in indoor rooms, which in turn lead to serious problems such mould growth. With a Testo thermal imager, you can reliably detect areas at risk of mould, thus preventing subsequent damage to the building.

After the input of the ambient temperature and air humidity in the room being examined, the imager automatically calculates the dewpoint and compares it with the measured surface temperature value. Any potential mould risk is then displayed in traffic-light colours (red, yellow, green) in the imager display – and you immediately identify where there is a need for action.

Testing the air-tightness of new buildings (blower-door)

Building thermography in combination with BlowerDoor®, for professional consulting in building management

The combination of building thermography and BlowerDoor has really proven its worth in the testing of new buildings: The process involves building up a pressure difference of around 50 Pa between the surrounding area and the interior of the building. This creates a negative pressure in the building and cool outside air can flow inside through leaky joints. Typical cold plumes develop. This temperature difference is clearly visualised using a thermal imager.

Building thermography can be used in this way to locate any inadequate points at an early stage. Required insulation measures can therefore be introduced before facings and fittings for the new build make repair work complicated and costly.
