*2.1.5 Limited knowledge and information regarding the economic benefits and prospects of green architecture*

Inadequate knowledge and information regarding the economic benefits and prospects of green architecture also serve as a barrier to the utilisation of green architecture. The availability of information as regards to the competitive advantages the use of green architecture offers is considered to be worrisome in most developing countries [46–48]. William and Dair and Azeem et al. identified a lack of knowledge, understanding, and information as a significant barrier to the successful delivery of sustainable architecture [37, 49]. Similarly, Alabi observed a low level of awareness regarding the concept of sustainability among most construction stakeholders in Nigeria [50]. Therefore, for green architecture to be widely accepted and used for construction projects, there is an urgent need for public awareness regarding the financial, economic, and environmental benefits of green architecture to society. Also, the numerous advantages of green architecture must be documented and communicated to all relevant stakeholders in order to expand and its use. Furthermore, there should be platforms which help built environment professionals to quickly disseminate information regarding the benefits of green architecture to the general public.
