Environomical analysis of green building having various window-to-wall ratio

The building industry is one of the most energy-intensive in developed countries. To reduce climate change emissions across a building’s entire life cycle, in addition to minimizing energy consumption during the operational phase, consideration should be given to the embodied energy and CO2 emissions of the building itself. Window-to-wall ratio (WWR) is a building parameter that plays a vital role in inside lighting and temperature. Light is a significant asset with characteristics of both radiometry and photometry. In the present work, environomical analysis of the various green buildings has been analyzed.
