Sustainable development and the application of its objectives in architecture and interior design are a major source of inspiration and simulation in interior architecture and design. The simulation methods of biological and ecological systems are an essential source of design thinking under the specific objectives of sustainable development. By defining sustainable development principles and objectives, we have been able to employ those terms and elements of architecture in general and internal design in particular by analysing those vital systems. The biological simulation -based designs have produced applications that included digital technology and digital engineering science. The designer has helped to create more effective and efficient designs and has included sustainability as a key focus in the traditional and digital design process and its various applications in the area of interior design.
Most quality-of-life studies of individuals are used through design, which describes the relationship between macro-environmental, local, personal, social, health, economic and design areas. The indicator under each area is designed to give details of biological and ecological simulations that integrate their design vocabulary with the surrounding natural environment and achieve sustainable development goals.
The approach to sustainable development is a modern one and is almost linked to all human sciences, including urban design science, which aims to create the technical and functional link between architecture and planning - and sustainable development is linked to design aimed at achieving sustainable urban design, which is still in its ideas and applications in the initials. 
As we move into the digital technology age, the challenge for sustainable development is to understand what has been digitally arrived at and build this into a global knowledge base that effectively plays its role in sustainable design thinking at the international and local levels. Therefore, these methods must be developed and biological simulation presented as a key element with a major potential impact that is a combination of design methods to synthesize sustainability and system analysis, which are largely based on digital and engineering models, provide a more traceable way forward in building sustainable designs, and internal architecture design requires that these interventions be integrated to address these environmental challenges with the least negative impact on our environment that can achieve a detailed understanding of complex and interconnected design-ecosystems. This, in turn, requires design tools that can reflect the essence of these systems and allow them to explore their dynamics and the potential consequences of alternative interventions through research and study of a range of axes, the most important of which are:
The importance of biological simulation in achieving sustainable development goals.
Biological simulation applications in sustainable development.
Challenges and constraints of biological simulation in design.
Sustainable development goals and mechanisms for their achievement in internal design.
