DUBAI, UAE, 21 November 2022: To meet the needs of HVAC design engineers, Carrier launched a new version of Hourly Analysis Program (HAP), its peak load and energy modelling software.

To reduce the time and effort required to create high-quality building models, HAP v6 combines a streamlined workflow with an extensive array of advanced 3D building modelling features, all woven into a core design that continues to be easy to learn and use, Carrier said while making the announcement of the launch through a Press release.

“Throughout the development process, Carrier worked directly with engineers in mechanical, electrical and plumbing (MEP) design firms,” said Jim Pegues, eDesign Software Development Manager, Carrier. “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.”

Out of the discussions with consulting engineers, design/build contractors, HVAC contractors and facility engineers arose the key features and approach for HAP v6, Carrier said. New powerful features were added for graphically defining the building model, the company further said, adding that an engineer sketches over building floor plans to define boundaries of rooms, and the software automatically calculates dimensions and areas.

According to Carrier, HAP v6 offers many technical upgrades to reduce what used to take a few days of labour to a couple hours of engineering time for building model creation. It integrates with the U.S. Department of Energy’s EnergyPlus™ calculation engine to provide cutting-edge system simulation capabilities, the company said. It utilises the ASHRAE Heat Balance load calculation method to represent building physics more accurately, the company added.

According to Carrier, HAP v6 features a global weather library, including 7,400 stations. Existing features for modelling 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, the company said.

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