The Quick Plant Energy Profiler, Release 1.1.3

The Quick Plant Energy Profiler, or Quick PEP, is an online software tool that helps industrial plant personnel quickly understand how energy is being used at their plant and how they might save energy and money. Quick PEP is a tool that can help the user quickly diagnose the energy situation at his/her plant. The tool is meant to give an overview of the energy that a plant purchases and the major systems that consume energy at the plant. Quick PEP will provide a report that helps the user understand where the largest opportunities are for energy and cost savings. The Quick PEP tool should be the first step in identifying areas for potential savings at the plant. Once those areas have been identified Quick PEP provides a broad list of potential next steps that the user could take to begin realizing energy and cost savings.

Chilled Water System Analysis Tool (CWSAT) Version 2.3

Release Date: October 5, 2007

Use the Chilled Water System Analysis Tool (CWSAT) to determine energy requirements of your system, and to evaluate opportunities for energy and costs savings by applying improvement measures. Provide basic information about an existing configuration to calculate current energy consumption, and then select proposed equipment or operational changes for comparison. The results of this analysis will help you quantify the potential benefits of chilled water system improvements.

NOTE: Because of the size of the file for this software tool, users should download only if using a T1 or similar connection. To Install: Please follow these instructions to ensure complete installation of the tool. First, create a folder for the new content. Then, extract the Chilled Water System Analysis Tool file to this created folder. Launch the program by double-clicking the "CWSAT23.EXE" file.

The entire "WEATHER" folder and CWSAT23.EXE files need to be within the same directory to work. You will also need the msvbvm60.dll support file to run MS Visual Basic 6. This file should already be located in the system directory of your hard drive.

Release Notes:  Several updates were made in Version 2.3, including the addition of Canadian cities to the weather database and modifications to input limitations and restrictions (for example,  higher chilled water supply temperatures are now allowed). This version also corrects minor user input bugs/issues for improved functionality. The fact sheet and user manual for Version 2.1 are still valid for the new version.
