contents and occasion of the intent:

Contrary to the until now predominating opinion, that the receipt of corrosive damaged glass paintings is guaranteed with the mounting of a protection glazing of the glass windows, this current example shows that a lasting protection of the medieval glass paintings is possible only in dependence with a regular control of the environment conditions despite the conservation/ restoration and mounting of a protection glazing. Therefore, the biggest significance is attached to the development of a especially on the particular environment conditions harmonized care- and control conception, wherewith can react quick and individual on the preservation of the inventory in the future. 

The effects and consequences of environment-induced factors on the choir windows are to find out in the project, to formulate requests and strategies of the treatment from it, and because of this to save the lasting preservation of the art-historically and culture-historically valuable glass paintings. In the foreground stands the development of control plans and utilization requests for a lasting protection of the glass paintings. For the entire church area, a concept for the climatisation is to be worked. This will essentially be determined by the interaction of ambient air, construction cover, outside climate and utilization beside the demands on the part of the glass paintings.

In the result, the requirements shall formulate for the regulation of the air conditioning and are picked the type of the technical support. Through an interdisciplinary cooperation with conservationists, restorers, architects in charge, nature and material scientists, art historians as well as  cooperation’s with the university’s in Freiberg and Erfurt, the until now executed building measures shall in and at the Divi Blasii church rethink the interventions in the glass painting substance, assesses and is adjusted in order to still be able to present the medieval glass painting continuance in the church after the preservation and restoration. Over the total time of the project, the climate data become directly regarding the ambient air and the special situation of the sanctuary as well as at the windows and investigate reference to the outside air. The developed measuring model grasps the individual measuring data, with what calculations, prognoses and graphs will be possible to the until now named influences, in the described interval. The data of climate measuring should put frankly in what way lacks of the outside protection glazing or at the area climate are responsible for the onward damages at the glass paintings.  Standards and requests for the further handling with the glass paintings are fixed with it.
