[Equest-users] Generalized Way to Calculate TEDI

[Bishop, Bill]

Hi Austin,
I had never heard of TEDI (Thermal Energy Demand Intensity) before. Seems to be a Canada thing (for now?). This looks like a relevant reference:
https://www.cagbc.org/cagbcdocs/zerocarbon/CaGBC_EMG_for_ZCB_v01.pdf
I don’t have a simple answer but I think you should be able to calculate it using a combination of these reports:

  *   SS-D Building HVAC Load Summary
  *   SS-A System Loads Summary for [all systems]
  *   SS-B System Loads Summary for [all systems]
This report includes eQUEST modeling of two building types, with reported TEDI for each. If you can contact Samantha Menard of EQBP, maybe she’ll share how she did the calculations.

Please share with the group once you figure it out.

Regards,
~Bill

Hi All,

Does anyone know of an easy way to calculate TEDI from eQuest? Or at least a generalized strategy? I have a number of models with different HVAC systems and it seems like it's going to be ad-hoc for each one.

Let me know, thanks!

Austin
