More natural light is transmitted through glazing with higher VLT values, but a higher VLT value tends to correlate with a higher solar heat gain coefficient (SHGC). Assess the optimal balance of these values, along with U-value, based on the project’s climate and heating and cooling needs, as well as the orientation of each elevation. These values are available on manufacturers’ specifications.
