Calculates detailed HVAC load reports for heating, cooling and airflow capacities. Based on ASHRAE algorithms, you are assured of accurate results and valid designs.

The intuitive Windows graphical interface makes Load Express a powerful engineering tool with a very short learning curve. The “rookie” or experienced user can quickly and accurately perform load calculations for small to medium-sized light commercial buildings with confidence.

Create project files with Load Express in just 4 easy steps. Select a weather profile, enter simulation parameters, define the zones/rooms in the building and create air handler descriptions. Expandable, built-in libraries of building design parameters streamline your data entry time. Explore different design options using the “Alternative” feature.
