The calculation engines in EnergyPro that are now used for Title 24 code compliance are developed and maintained by the California Energy Commission. The new Residential and Nonresidential calculation engines they provide are significantly slower than the prior ResSim and DOE-2 engines we provided in older versions of EnergyPro. The new engines incorporate CSE and EnergyPlus, which are more powerful than the older calculations, and simulate the zones much more thoroughly, resulting in longer simulation runtimes.

To speed up run times, you can select the Quick Analysis option, which will run a partial year simulation. electricity voltage in canada In the bottom left, click on the Calculations. In the list that appears above, select either Res T24 Performance or NR T24 Performance. On the right will appear the option for Quick Analysis. This will cut your runtime in half. However that option will trigger a report that includes a watermark that states “Not useable for compliance” since you must run the full year for code compliance.

Option 1 – This approach requires you to treat the plant chilled water and hot water as purchased commodities thus removing any efficiency associated with the central plant from the model. You will model your HVAC systems as normal and input whatever central plant is appropriate for the chillers, boilers, towers and pumps (you will be discarding all of these numbers so it is not important). electricity facts for 4th graders When running the calculations, under the Calculation Options, check the box for CSV reporting (covered in another FAQ) and uncheck Delete Temporary Files. Now you can run the calculations.

After the calculations are complete, you will open the CSV file in Excel and you will find hourly data for the various end uses (note the units of each column). The columns for Heating, Cooling, Heat Rejection and Pumps* can be discarded. On the far right you will find columns for Chilled Water and Hot Water demand for the building. These are the purchased commodities you will use to follow the DES guidelines. Any columns that represent normal building usage (lighting, fans, receptacle) should get multiplied times the virtual rate for Gas or Electricity (found on the EAC1 report). The Chilled Water and Hot Water use is multiplied times the rates given in the DES Guidance and you will have a spreadsheet that documents total energy cost for your building.

Option 2 – With this option you are allowed to model the actual efficiencies of the central plant in EnergyPro only you will scale the actual equipment according to the load served. Be sure you understand the documentation requirements given in the DES Guidance document from USGBC since this approach requires supporting data on the efficiencies you are using.
