Thermal imaging lends itself to detecting faults in a mechanical or electrical plant, but is equally appropriate for the identification of hot spots in buildings – an essential requirement for all those involved in energy conservation. The thermographer can quickly perform a survey which will highlight problems with:
- Missing, damaged or non-existent insulation
- Moisture damage
- Thermal bridges
- Drafts due to ill-fitting doors and windows
- Floors and roofing
- Anomalous pipes, radiators, ducts and other HVAC equipment
Surface temperature has started to play a major role in both audits and energy surveys, as it can be used to evaluate the condition of the building itself as well as the electrical, mechanical, HVAC and plumbing systems.
HVACR equipment is installed to provide an acceptable environment in terms of temperature, humidity and ventilation levels. This is required not only for the health and comfort of the occupants, but also to ensure the health of the building and, increasingly, to control spiralling energy costs.
This work is leading to the creation of planned preventative maintenance regimes, air leakage, moisture accumulation, blockages in pipes, and structural features behind walls. All can be detected with infrared technology and documented with thermal imaging cameras.
Why identify heat loss in buildings?
Heating and cooling a building consumes energy. Any reduction in heat/cooling losses will reduce energy consumption, leading to a direct and significant cost saving.
All businesses are becoming more aware of their corporate social responsibilities. Reducing energy usage is one aspect of this.
As part of the Kyoto agreement, Britain has to reduce its carbon emissions to 12.5% less than the 1990 emissions by 2012. In the UK ~45% of all carbon emissions come from buildings.
