Air quality and Climate effects on materials and cultural heritage

NILU has also studied the effects of air quality and climate change on built structures and materials, and on cultural monuments.

Indoor air quality and climate are very important for the conservation of cultural heritage in collections, historical buildings, archives and libraries.  With its A.Q.Services for Cultural Heritage NILU offer measurements of indoor air quality and climate and evaluation of the relative degradation risk for heritage objects.

Air quality and climate conditions are also very important factors for the degradation of materials and cultural heritage outdoor.

Changes in the climate involve changes in the values of climate parameters such as temperature and precipitation, both in terms of extreme values and averages. In Norway, there are concerns related to the possibility of increased and stronger precipitation events in conjunction with higher temperatures. In general this will result in greater loads on built structures and materials, both in the form of wear and in the risk of catastrophic failure.

Other effects of climate change relate to the in-migration and spread of new animal and plant species that can have adverse effects, such as pests in buildings and museums. Changes in the climate will likely increase expenses in many sectors of society. Maintenance costs will increase, due to wear and damage to buildings and infrastructure, or because of the costs of adaptation measures that will have to be put in place to avoid an increase in this kind of damage.
