Buildings made of any stone, brick or concrete are susceptible to the same weathering agents as any exposed rock surface. Also [[statue]]s, monuments and ornamental stonework can be badly damaged by natural weathering processes. This is accelerated in areas severely affected by [[acid rain]].<ref>{{cite book |last1=Schaffer |first1=R.

Accelerated building weathering may be a threat to the environment and occupant safety. Design strategies can moderate the impact of environmental effects, such as using of pressure-moderated rain screening, ensuring that the HVAC system is able to effectively control humidity accumulation and selecting concrete mixes with reduced water content to minimize the impact of freeze-thaw cycles. <ref> {{cite web |url=https://www.bchousing.org/publications/MBAR-Chronic-Stressors.pdf |title= Design Discussion Primer - Chronic Stressors |publisher=BC Housing |access-date=13 July 2021}}</ref>
