Select the design phase and reporting date. If you report project data each spring for the preceding year, make sure to save it in the appropriate year (e.g., when reporting data for 2020 projects in 2021, make sure to backdate to 2020).

Within each phase, users can track data on predicted energy use; , energy modeling software, responsible parties, and cost; fuel sources; renewable energy sources; embodied carbon; and additional inputs, which are all detailed in their respective articles.

Although T24 doesn’t include Site EUI on the cover page, you may still be able to calculate the Site EUI for non-residential projects from T24 documentation (see below). Additionally, there are some software like EnergyPro that MEP engineers use to extract the site EUI from TDV EUI with minimal effort. In either case, it is critical that you talk to your MEP at the beginning of the project and let them know that you are a 2030 Commitment signatory and you expect to receive the Site EUI in addition to the Title 24 documentation. You can find further information and Time Dependent Valuation calculators on this AIA California's Understanding EUI page. 

To calculate your non-residential building pEUI from T24 PRF-01 (Table U of NRCC PRF-01 page 21), follow steps below:

1. Find Table U – Energy Use Summary. This is usually found somewhere in the middle of the T24 PRF-1 forms.
2. Take either value in the green boxes and convert it to kBtus.
   1. To convert MWh to kWh, multiply by 1000. To convert kWh to kBtu, multiply by 3.412.
   2. To convert MBtu to kBtu, multiply by 1000.  
3. To calculate the pEUI, divide the converted value from either green box then divide it by the building area according to this formula: pEUI = Annual Energy Consumption (KBTU)/GSF
4. Some projects will have Proposed Design Site energy values in Therms (if the project uses natural gas) in addition to the Proposed Design Site energy values in MWh or kWh. In this case, the Proposed Design Site energy in Therms will need to be converted to kBtus then summed with the Proposed Design Site in MWh/kWh (after the conversion to kBtus).
   1. To convert Therms to kBtus, multiply by 100
5. If your project has on-site energy, subtract the on-site energy value from the total Proposed Design Site energy before calculating the pEUI in step (3).
