LEED, BREEAM, Green Pyramid, and TARSHEED Rating 
Systems are incapable of maintaining the health and welfare of building 
occupants, so many claims have been against developers, engineers, and 
real estate owners, due to sick building syndromes (SBS) related to the 
poor design of the aspect. Many of the environment-related aspects directly 
contradict the health-related aspects. The S.R.A focuses on the sustainable 
aspects, regardless of the health impact of humans using this building.
Light can affect human health through the systems visible and invisible to 
the eye and its impact on eyestrain and headache. Stress and depression are 
two of the most common psychological disorders and diseases in modern 
communities living in apartments and dark, narrow houses. As a result, it 
appears that the effect of light and spatial proportion in modern small 
houses plays a significant role in the occurrence and treatment of these 
disorders. We could prevent and treat these disorders with flexible design ,
lighting ,and optimal space design. The main objective of this study is to 
design well-lit spaces to preserve the health and well-being of the 
occupants of the building and to achieve visual comfort through the 
application of the elements that lead to this, in addition to the building 
being compatible with sustainable rating systems and knowing any system 
concerned with lighting and human comfort.
