Glazing g-value

Question

Could you tell me in which box on the Glazing Data window in Hevacomp I can enter the glazing g-value? Thanks.

Hi Steve, 
 The most important point to be aware of is that different parts of the Glazing data menu are used depending on what calculations/simulations you are looking to run. 
 While a G value is displayed, it cannot actually be changed manually as it is calculated according to the layers of glazing that have been set up, as below. Please note that the layer data is used by Simulations only.

On the other hand if you are looking to run Design Database calculations then the information in the top right corner of the Glazing data menu is used. Your glazing manufacturer will be able to provide you with this data. 
 A more thorough explanation of the above can be found here.
