This research paper contributes to investigating the extent to which knowledge and mechanisms of biological water management can be explored to inspire new solutions for buildings and how biologically developed methods that can be used both to provide water and obtain it from the outer casings of buildings interacting with nature can be explored, and the research methodology is first carried out by examining various examples of organisms that have highlighted and demonstrated their natural success in the good management of For the water and work of a detailed analysis of the mechanisms of these organisms in the provision and management of water, ii detailed presentation and analysis of a set of global examples simulated to the environment, which has a precedent in the application of the concept (water management through an environmentally adapted outer shell), thirdly comes the applied study by proposing checklist models with proposed relative weights based on previous studies to measure the success of analytical examples in accomplishing the task. Results: Namibia Hydrology Center ranked first with the highest percentage of use of naturally inspired water management functions, Namibia Hydrology Center ranked first with the highest percentage of use of naturally inspired water management functions, and the first (water collection) job was ranked first with the highest percentage of repetition in all study cases, while the job (water storage) was second with a percentage of 63% of repetition, and reached 100% of repetition in all study cases, while the job (water storage) was second with a percentage of 63% of repetition. The element (water collection) in the first place with the highest percentage reached 36% for the total size of all other elements of water functions, while the element (water storage) in the second place reached the highest percentage reached 23% relative to the total size of all elements of other aquatic functions, Conclusions: the strategies of balance and biological water management in organisms in nature to provide innovative solutions for the design of the exterior of the building, especially in the third world countries new to this type of building where water management strategies are transferred from nature to the architectural design of the covers of external buildings, taking into account the choice of natural strategies suitable for each environment and place, as well as the research study reached that the strategies of living organisms in water management, whether synthetic or behavioral adaptation, boils down to a set of key biological functions, namely (acquisition of water - water transfer - storage of water- storage Water - preventing water loss - water purification).
