How can I obtain the loads I need for GLHEPRO from eQUEST?

The following instructions were provided by one of Dr. Spitler’s former graduate students. 

Step 1: Setup an hourly report for building HVAC system cooling and heating loads. An example of eQUEST/DOE-2.2 input file is given in the following:

$ ---------------------------------------------------------  
$              Hourly Reporting  
$ ---------------------------------------------------------

"Hourly Report Block 1" = REPORT-BLOCK     
  
VARIABLE-TYPE    = BUILDING-HVAC  
  
VARIABLE-LIST    = ( 1, 2 )  
  
..

"Hourly Report 1" = HOURLY-REPORT    
  
REPORT-SCHEDULE  = "Hourly Report Schedule"  
  
REPORT-BLOCK     = ( "Hourly Report Block 1" )  
  
..

Step 2: Run eQUEST simulation and export the hourly results to a CSV file with the "Export Hourly Results..." utility provided in the "File" menu of eQUEST.

Step 3: Load the two columns of data: "Building cool load (coils+losses&gains) (Btu/hr)" and "Building heat load (coils+losses&gains) (Btu/hr)", into the "Peak Loads Analysis Tool" of GLHEPRO (V4.0) following the tool instructions, then use the tool to generate the monthly cumulative/peak heat/cool loads. Also, estimate the "duration of peak hours" with the tool.

Step 4. Copy and paste these data into GLHEPro's "Heat Pump Load" table.
