A quick overview on general features of designPH
A number of built-in features in designPH allows for a quick model editing and a thermal analysis of a building.
For editing building model, designPH provides the following features:
NOTICE: It is important to note that designPH cannot confirm if you have reached Passivhaus standard, but it will help you achieve a design that is capable of achieving the standard. The energy demand calculation within designPH uses the annual method (seasonal method according to EN ISO 13790) to calculate a specific space heat demand for the heating season only; designPH cannot give a result for space cooling demand nor an indication of overheating risk (overheating should be checked in PHPP). For cooling climates you can still use designPH to enter the building geometry then perform the full analysis after exporting to PHPP.
Introduction and workflow with designPH
designPH has been developed by the Passive House Institute to work together with the PHPP. Together you can use designPH and PHPP for the planning of high efficient buildings.
designPH is a plugin for the SketchUp 3D design software which provides a new intuitive graphic input for PHPP.
designPH facilitates the pre-planning and energy optimization in 4 steps:
1. Draw your project in SketchUp or start from a saved model
2. Select the correct orientation and climate region within designPH
3. then, either:
4. Export to PHPP to further refine the design and check the project can meet Passivhaus standard
the designPH interface
The primary designPH user interface is provided through a web dialog window which shows lists of the elements in the model, the properties that are assigned to them and libraries of properties such as assembly types, glazing types and frame types. The web dialog window is sub-divided into tabbed sheets with collapsible panels, allowing different information about the model to shown in the main view.
The designPH main toolbar:
The designPH window toolbar
All of the standard Sketchup menus and tools are available for your use as are those belonging to other plugins.
designPH context menu items
designPH adds a number of functions to the context menus which appear when you right-click on a model element (the choice of functions available will depend on what is selected). Through these menu options you can edit properties of surfaces and windows for example.
