Carrier updates modelling software


22 November 2022

Carrier has released a new version of Hourly Analysis Program (HAP), its peak load and energy modeling software. 

The programme is designed to reduce the time and effort required to create high-quality building models, combining a streamlined workflow with advanced 3D building modeling features.

“Throughout the development process, Carrier worked directly with engineers in mechanical, electrical and plumbing design firms,” said Jim Pegues, eDesign software development manager. “Some were using previous versions of HAP and some were users of other system design applications. We focused on the ways engineers actually work, and listened to what they like and don’t like about their current software.”

HAP v6 is said to offer many technical upgrades and integrates with the US Department of Energy’s EnergyPlus calculation engine. It utilises the ASHRAE Heat Balance load calculation method to represent building physics more accurately.  

A global weather library including 7,400 stations is included. Existing features for modeling the energy performance of modern HVAC equipment and controls have been upgraded to help building owners better meet their sustainability and environmental targets for greenhouse emissions.

Carrier says most current users can transition to HAP v6 for free at their own pace, continuing to use v5 for as long as necessary.
