The role of preventive maintenance in protecting heritage and valuable buildings from the risks of climate change

The phenomenon of climate change is considered one of the most important 
environmental problems resulting from the increase in unsustainable human activities 
within the built environment with its direct or indirect connection with the increase in 
consumption and mismanagement of non-renewable energy sources. Temperatures, 
winds and increased precipitation (floods) ... etc. The phenomenon of climate change is 
also a global problem that can be confronted, reduced, or mitigated as much as 
possible, to preserve all the physical components that make up the existing urban 
environments, the most important of which is of course the physical structures of the 
existing architectural heritage.
 The phenomenon of climate change and its accompanying extreme natural 
phenomena is considered one of the most important main factors that now have a 
negative impact on the sustainability of the physical structures of the architectural 
heritage and its durability over time, not only at the local level, but extends to the 
regional and global levels. (If it intersects with the tangible architectural heritage) to the 
destruction and loss of the cultural value contained in this heritage as an important 
resource of life and a source of inspiration within the societies incubating this heritage, it 
is irreplaceable and irreplaceable if it is damaged or destroyed. We live in the present 
and in the future, and we must pass it on to future generations.
From the above it is clear the importance of research in protecting the existing 
architectural heritage from the dangers of climate change, and preventing, mitigating or 
limiting the negative effects associated with the imbalances in the usual climatic 
conditions (such as extreme natural phenomena) to which heritage buildings and 
valuable urban environment surrounding them are exposed, whether they are exposed 
to these The conditions are continuously or intermittently, by supporting their resilience 
and sustainability and the sustainability of the conservation programs applied to them in 
the face of climate change risks over time, whether at the level of the architectural and 
construction elements of heritage and valuable buildings or at the level of the 
surrounding urban environment.
