õhusaastumine
Õhusaastumine refers to the gradual or accelerated decline in the condition of buildings due to various factors over time. This process affects both the structural integrity and the aesthetic or functional aspects of a structure. Natural aging of materials, such as wood, concrete, or metal, combined with environmental exposure—including weathering, moisture, and temperature fluctuations—can lead to deterioration. Human factors, like inadequate maintenance, design flaws, or improper use, also contribute to the degradation. The consequences may include safety risks from structural failure, reduced energy efficiency, decreased property value, and environmental impacts from the disposal of aged building components. Proactive measures, such as regular inspections, timely repairs, and the use of durable materials, help mitigate these effects and extend a building's lifespan.
