Energy Plus International is an official reseller of designPH1.1 for Bulgaria.

The new plugin, designPH1.1, is a 3D modeling interface which was developed by the Passivhaus Institut in Germany. It allows for graphical input of energy related design data into the Passive House Planning Package (PHPP).  DesignPH uses the SketchUp framework.

designPH1.1 is closely linked to the PHPP.
designPH1.1 and PHPP form a unity, when it comes to engineering the highest building energy efficiency.
designPH1.1 is the new, interactive and graphically oriented input interface for the PHPP.
designPH1.1 is a plugin for the free to use and downloadable 3D CAD software SketchUP.
