PH-Tools
Open-source tools for Passive House energy modeling. Build, certify, and export — all from Rhino / Grasshopper.
Projects
Libraries and tools for Passive House workflows.
Honeybee-PH
Passive House data model extending Ladybug Tools. Add PH-style attributes to Honeybee models for certification with WUFI-Passive or PHPP.
honeybee-phPHX
Convert Honeybee-PH models to and from WUFI-Passive XML and PHPP Excel. The serialization engine behind PH-Tools exports.
PHXCarbonCheck
Embodied carbon analysis for building assemblies. Evaluate envelope decisions through a carbon lens.
CarbonCheckHoneybee-REVIVE
Retrofit analysis and deep energy retrofit modeling for Honeybee. Evaluate improvement scenarios and phased upgrades.
honeybee-REVIVEPH-ADORB
Annualized De-carbonization of Retrofitted Buildings. Life-cycle carbon and cost optimization for retrofit projects.
PH-ADORBPH-Units
Unit conversion library for Passive House workflows. Handle SI/IP conversions for all common building science quantities.
PH-UnitsWhy 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.
WUFI-Passive or PHPP
Export to PHPP v9/v10 or WUFI-Passive. Multiple language options (English, Spanish, German) and unit systems (SI, IP).
