The role of designPH as a PHPP plug in
Here is an article in the RIBA journal on the role of designPH to model effective retrofits
Some new features of PHPPv10 explained - please expand the selections
|The Passive House Planning Package PHPP 10 contains a new external too, the so-called Room Data tool. The Room Data tool allows the systematic determination of essential input variables for the PHPP providing assistance especially for complex projects. It can easily be extended and adapted depending on the requirements of the project. The calculated intermediate results can be transferred into the PHPP.
This file contains templates for secondary calculations to the PHPP in different worksheets. It also serves to document changes in the calculations, which is very useful for communication among those involved in the project.
|In the worksheet MONI, the PHPP calculation can be adjusted to actual boundary conditions such as weather data or room temperatures, in a given measurement period in order to make the actual consumption values comparable with the calculation results in the PHPP. Several results in PHPP, like heating demand, energy demand for domestic hot water or electricity, can thereby be compared to monitoring results|
|The calculation of he overheating frequency was supplemented with a stress test for summer comfort when passive cooling concepts are used. Summer comfort and the frequency of overheating are greatly dependent on the behaviour of occupants in the building, which influences factors such as air exchange via windows in the summer, night ventilation, temporary shading or internal heat gains.
Besides a set of pre-defined risk parameters, the manual input of different user behaviours is also possible
|New certified components categories have been added to PHPP. In addition to heat pumps you can now enter combined ventilation and split units.
In the worksheet cooling, the seasonal energy efficiency ratio of the cooling units can now be determined more accurately based on the device properties. Other types of operation, e.g. combined supply air and recirculation cooling via the ventilation system were added.
The Passive House Planning Package (PHPP) is a design tool produced by the Passivhaus Institut for use by building architects and designers. PHPP incorporates the energy specifications for quality-approved Passivhaus buildings from the Institut in a manual and downloadable files.
designPH 2.1 is the new interactive and graphically oriented input interface for PHPP. It is a plugin for the popular 3D design software SketchUp and is available for Apple and Windows operating systems. A full version of the PHPP software is required to be able to use it.
