By ensuring good indoor air quality, the IgCC helps to create healthier and more comfortable living and working environments.

Sustainable materials and resources are another key focus of the IgCC. The code encourages the use of materials that are environmentally responsible, such as those that are recycled, rapidly renewable, or locally sourced. It also includes provisions for construction waste management, promoting practices that reduce waste and encourage recycling and reuse.

Resilience and adaptability are also important principles of the IgCC. The code includes guidelines for designing buildings that can withstand natural disasters and adapt to changing conditions. This helps to ensure that buildings remain functional and safe over their entire lifecycle, even in the face of environmental challenges.

Finally, the IgCC emphasizes the importance of integrated design and collaborative processes. By encouraging architects, engineers, builders, and other stakeholders to work together from the earliest stages of a project, the code helps to ensure that sustainable practices are incorporated into all aspects of the building process. This holistic approach is essential for achieving the high levels of performance and sustainability that the IgCC aims to promote.
