Buildings are one of the major sources of global energy consumption and CO2 emissions. According to a trusted source, industrial buildings and corporations account for 40% of energy consumption. Architects, engineers and developers are always striving to find a sustainable solution that can reduce greenhouse gas emission, which has become a potential threat to our ecosystem. They are more focused on designing buildings with the ecosystem in mind, especially for commercial projects like malls, institutions, manufacturing units, train stations and airports – any setting with huge operating cost and energy utility involved.
