Module 2 Manas

The document presents energy consumption and savings data based on various building design parameters, including orientation, window-to-wall ratio (WWR), roof insulation, glass properties, and window shading. Key findings indicate that a north orientation and a 20% WWR yield significant energy savings, while increasing roof insulation thickness shows diminishing returns. Additionally, using low-E double glass and higher shading coefficients leads to notable energy savings.
