Re: [EnergyPlus_Support] Cooling Load Calculation

Dear Sajal,

I imagine you're looking at the wrong thing …

In the early part of his "Table.HTML" there is a table with the title "End Uses.” This table is divided into some columns: Electricity [kWh], Natural Gas [kWh] Additional Fuel [kWh] District Cooling [kWh] District Heating [kWh] Water [m3], according to the source of energy used.

If so, just watch the values for "Heating", "Cooling" and "Fans" and convert them to GJ using the ratio 1 [kWh] = 0.0036 x [GJ / h].

Otherwise, based on Input/Output Reference Guide, it appears that your file is set to IDF kWh “ClassList" > "OutputControl: Table: Style". There is a possibility that the data are provided in:

- JtoKWH - Joules converted into kWh (1 / 3,600,000)

- JtoMJ - Joules converted into megajoules (1 / 1,000,000)

- JtoGJ - Joules converted into gigajoules (1 / 1,000,000,000)

- InchPound - convert all annual, monthly, economics and timebins tabular values to common Inch-Pound equivalent

Remember: the current options are limited to just how the energy is being Reported.

Dear All,
I calculated the following by using ILAS for 1 year.
Report: HVAC Sizing Summary
For: Entire Facility
Zone Cooling

Calculated Design Load [W] User Design Load [W] User Design Load per Area [W/m2] Calculated Design Air Flow [m3/s] User Design Air Flow [m3/s] Design Day Name Date/Time Of Peak Thermostat Setpoint Temperature at Peak Load [C] Indoor Temperature at Peak Load [C] Indoor Humidity Ratio at Peak Load [kgWater/kgAir] Outdoor Temperature at Peak Load [C] Outdoor Humidity Ratio at Peak Load [kgWater/kgAir]

Here, Calculated Design Cooling Load [W]= 39246.61 W .. is this calculation for per second ??? and if I want to convert this to GJ per Hour how can I do this?? Thank you.

Best Wishes,
