Fresh air for the Afrakapelle: New fan to combat mold problems!

In the Afra Chapel, located on the north side of Speyer Cathedral, high humidity and associated mold problems have been repeatedly observed in the past. Cathedral builder Hedwig Drabik describes the situation as challenging, as the humidity was regularly over 70 percent. To counteract this challenge, efficient measures have now been introduced. This includes installing a special fan in the organ, which is intended to help significantly improve air circulation. This measure is part of a comprehensive redesign of the air conditioning technology, which is intended not only to regulate the temperature of the room, but also to specifically control the ventilation.

The water flow outside was adjusted in advance and a special coating was applied to the interior. Measurements have shown progress and this is seen as a positive sign. These specialist tactics are intended to ensure that the Afra Chapel remains in a welcoming condition for weekday masses, weddings and services for pilgrim groups.

Stems for mold prevention

Mold is not just an aesthetic problem; it can cause significant damage to the building structure and potentially pose health risks. Therefore, the prevention of mold in buildings is a central issue. The risk increases particularly in poorly ventilated rooms, as high humidity promotes the growth of mold. Preventive measures are therefore essential. These include, among other things, adapted ventilation, controlled heating and regulation of air humidity, as the Raumluft-Shop recommends.

• Angepasste Belüftung
• Regelmäßiges Stoßlüften (2-3 Mal täglich)
• Kontrolliertes Heizen mit einer Mindesttemperatur von etwa 16 Grad Celsius
• Optimierung baulicher Gegebenheiten, wie Dämmung und Abdichtungen

Causes of mold can include high humidity and insufficient air circulation. Activities such as cooking and showering, as well as structural defects such as leaky roofs or poor window systems, also contribute. A certain degree of vigilance is required here in order to act in a timely manner and avoid any damage.

The drainage at Speyer Cathedral

Another big issue at the cathedral is drainage. This is perceived as urgent after the recent heavy rain events. The existing drainage systems are often no longer sufficient to drain away excess water, leading to damp walls and noticeable damage. Some downpipes on the western building have recently been reworked, but the situation remains serious: old and sometimes severely damaged pipes continue to pose a problem. A targeted approach to drainage is therefore essential.

In summary, it can be seen that the church is making great efforts not only to preserve the historical value of the Afra Chapel, but also to ensure the health of its visitors. Mold and moisture are serious issues that require continued vigilance. The Federal Environment Agency's updated guide to mold prevention and remediation also offers valuable insights that can benefit both experts and affected residents.

The measures surrounding the Afra Chapel are an example of how both tradition and health can be preserved through technical innovation and sustainable practices. Those responsible are optimistic that the new systems and plans will bear fruit in the long term.
