Why Honeybee-PH?

Adds to Existing Workflows

Use your existing Honeybee modeling workflows to generate models for Passive House assessment and certification.

Single Model

Use one BIM model for all your assessments. From daylighting, to energy, to thermal comfort and full Passive House certification.

Gain Control

Configure your mechanical systems, detailed usage programs, and certification settings — all from within the familiar Grasshopper platform.

Make Non-Residential Easy

Dramatically simplifies non-residential building modeling with access to the huge Honeybee-Energy program library. Easily manage complex occupancy, lighting, and equipment loads.

Simplify Certification

Automate reporting of envelope types, thermal bridges, interior TFA/iCFA, and room-by-room ventilation airflows. Standardize your certification workflow.
