[Equest-users] Generalized Way to Calculate TEDI

[Austin Selvig]

Hi All,

I chatted with Samantha, as well as Brian Fountain, and they agreed that
you can just take the SS-D heating total and convert it to kWhe then divide
it by the floor area of the building in m^2 to give you the TEDI.

Nice to have a straightforward approach.

Cheers,

Austin
