BIM2PHPP: A new BIM-based tool for passivhaus design with PHPP

Abstract

The Passivhaus buildings can significantly reduce energy consumption when compared to conventional practice for new buildings. Achieving the Passivhaus certificate requires complying to a set of rules and meeting the energy limit criteria. Assessing building energy performance is conducted using the Passive House Planning Package (PHPP). Users can input all required information manually, or they can prepare information needed using SketchUp with DesignPH plugin. In this paper, we developed a new computational workflow for data exchange between Building Information Modelling (BIM) and PHPP. This research aims to develop a BIM-based tool that facilitates prescribed evaluation by PHPP. The proposed tool can collect, process and export BIM model data to the PHPP through Dynamo - a visual scripting platform for Revit. We demonstrated the automation of Passivhaus evaluation by facilitating both geometrical and non-geometrical information interoperation between BIM models and the PHPP tool.
