Navigate to your downloaded file to bring the project into your local HAP workspace. Safety and Troubleshooting

Downloading a typically refers to retrieving an archived project from Carrier’s Hourly Analysis Program (HAP) , a tool used by HVAC professionals for peak load and energy modeling. Because these projects consist of many data files, HAP uses a built-in "Archive" feature to bundle them into a single file for easy sharing. What is a HAP Working File?

: These files allow engineers to transfer complete project data—including weather data, wall constructions, and system schedules—from one computer to another. How to Use the Downloaded File

: When you "Download" this file (often sent via email or cloud storage), it is usually in a compressed format (like .zip or HAP's proprietary archive format) to keep all project components together.

: Occasionally, "HAP" may refer to a video codec used in high-performance media playback or a haplotype file in genomics. Ensure you are using the correct software for the file's actual purpose. If you’d like more tailored help, let me know: Are you using Carrier HAP (HVAC software)? Did you receive this file from a colleague or a website ?

You cannot simply "open" the file by double-clicking it if it is a specific HAP archive; you must use the function within the HAP software.

In the context of HVAC design, a "working file" is the active data set for a specific building project.
