Historically valuable buildings are threatened by floods, moisture and mold damage in the same way as other buildings. Because these buildings have cultural values that are irreplaceable, it is important to prevent damage.

Maintenance will be even more important in a changing climate. More frequent maintenance will also be required. A well-maintained house is more resistant to the damage climate change can cause. As an example, clearing gutters and having good drainage can prevent the devastating effects of a torrential rain.

For the historically valuable buildings to continue to be utilized and conserved energy efficiency is, in the long term, a prerequisite.

Energy saving requirements are affecting historically valuable buildings and it is possible to save energy without compromising the risk that this valuable cultural heritage will disappear. These issues are addressed in the EU project Co2olBricks and Energy Agency's research programs Save and Preserve.
