Please note that following tools are available in German only

Sound protection – tools and calculations
These calculation sheets were prepared within the framework of the Research Group for Cost-effective Passive Houses Phase IV and V (Volume 34 - Sound protection for heat pumps and compact heat pump units in Passive Houses | Volume 41 – Cooling in non-residential buildings)

These are intended as aids for approximate calculation and dimensioning of sound protection measures by the designer:

Decibel arithmetic
Evaluation of low-frequency sound in accordance with DIN 45680
Sound emission of ventilators
Sound absorbers
Insulation of structure-borne sound
Encasement
Insulation of air-borne sound
Acoustics of a room

PHVP 2002
The Preliminary Passive House Planning Package PHVP 2002 is a simplified version of the Passive House Planning Package (PHPP) which is available free of charge. The PHVP is intended to provide a rough idea of the structural and technical requirements for basic evaluation and the preliminary design phase, and for the respective calculations (building services systems and influence of the surroundings are not taken into account).

SommLuft
Air exchange through windows is a key parameter for indoor climate in warm climates and/or time periods. Among other things, it is necessary for evaluating the indoor climate in combination with the “Summer” worksheet of the Passive House Planning Package. The Excel-based “SommLuft” tool allows users to estimate the air exchange through windows for the configuration of appropriate window openings.
