Tinytag data loggers helping to increase energy efficiency in galleries

Tinytag temperature and relative humidity data loggers from Gemini have recently to help increase energy efficiency in a display gallery after being used in trials to monitor environmental conditions.

The National Museum Cardiff was recently monitored, and it was discovered that enormous savings were being made from modifications to environmental management in display galleries.

Many museum galleries are air conditioned as fluctuations can result in damage to objects because of swelling or shrinkage, as many objects absorb and desorb moisture from the atmosphere.

Christian Baars, the Senior Preventive Conservator, demonstrated that fluctuations tend to be minimal after dark. Several trials were undertaken in the Geology galleries, where a number of environmental monitors – including seven Tinytag Ultra 2 TGU – 4500 data loggers – were installed.

These trials showed that both temperatures and relative humidity in the galleries and inside display cases were stable, and there was hardly any difference between nights with air conditioning on or off.

Consequently, air conditioning is now switched off in these galleries each night, resulting in substantial energy savings while still maintaining an environment save for objects.

Christian comments, “We chose the Tinytag Ultra 2 because it is yellow (and therefore easy to see), robust, and the software is user-friendly – it’s easy to import data into EXCEL for analysis.”
