====== PHPP – Passive House Planning Package ======

===== PHPP – More than just an energy balance =====

The **Passive House Planning Package (PHPP)** (order [[http://passiv.de/literaturbestellung/index.php/en/?task=view&category_id=1|here]]) contains everything necessary for designing a properly functioning Passive House. The PHPP prepares an energy balance and calculates the annual energy demand of the building based on the user input relating to the building's characteristics.\\
The main results provided by this software programme include:\\
* The annual heating demand [kWh/(m²a)] and maximum heating load [W/m²]\\
* Summer thermal comfort with active cooling: [[.:phpp_-_the_passive_house_planning_package:calculations_in_hot_and_humid_climates:phpp_active_cooling_algorithms|cooling demand [kWh/(m²a)]]] {{:picopen:members_only.png?20}} and maximum cooling load [W/m²]\\
* Summer thermal comfort with passive cooling: frequency of overheating events [%] (see [[:a_simplified_method_for_determining_thermal_comfort_in_summer_for_buildings_without_active_cooling|passive cooling tool]] )\\
* Annual primary energy demand for the whole building [kWh/(m²a)]

The actual PHPP programme is based on Excel (or an equivalent spreadsheet software programme) with different worksheets containing the respective inputs and calculations for various areas. Among other things, the PHPP deals with the following aspects:\\
* Dimensioning of individual components (building component assemblies including U-value calculation, quality of windows, shading, ventilation etc.) and their influence on the energy balance of the building in winter as well as in summer\\
* Dimensioning of the heating load and cooling load\\
* Calculating domestic hot water (DHW) demand and design of DHW systems.

  * Dimensioning of the mechanical systems for the entire building: heating, cooling, hot water provision \\ * Verification of the energy efficiency of the building concept in its entirety

The calculations are instantaneous, i.e. after changing an entry the user can immediately see the effect on the energy balance of the building. This makes it possible to compare components of different qualities without great effort and thus optimise the specific construction project - whether a new construction or a refurbishment - in a step-by-step manner with reference to energy efficiency. systematic variant management is also integrated. Typical monthly climatic conditions for the building location are selected as the underlying boundary conditions (particularly temperature and solar radiation). Based on this, the PHPP calculates a monthly heating or cooling demand for the entered building. The PHPP can thus be used for different climatic regions around the world.

All calculations in the PHPP are based strictly on the laws of physics. Wherever possible, specific algorithms resort to current international standards. Generalisations are necessary in some places (e.g. global established routines for shading), and sometimes deviations may also be necessary (due to the extremely low energy demand of Passive Houses, e.g. for the asymptotic formula for the utilisation factor), while for some areas there are no internationally relevant standards (e.g. with reference to dimensioning of ventilation systems). This approach has resulted in an internationally reliable calculation tool with which the efficiency of a construction project can be evaluated more accurately than with conventional calculation methods. (Read more about this in the section [[.:phpp_-_the_passive_house_planning_package:phpp_-_validated_and_proven_in_practice|]]) \\

**The PHPP forms the basis for quality assurance and [[:certification|certification]] of a building as a [[:certification:certified_passive_houses|Passive House]] or an [[:certification:enerphit|EnerPHit retrofit]].**The results of the PHPP calculation are collated in a well-structured verification sheet. In addition to the basic components of the PHPP already mentioned, various useful additions have also been made for the user's benefit. For example, the simplified calculation method based on the German energy saving ordinance EnEV has been integrated into the PHPP. Preparing an energy performance certificate for a project is facilitated by an additional tool. \\  \\ |{{:picopen:phpp_nachweis-blatt_en.png}}|

===== Continuously developed further =====

The first edition of the Passive House Planning Package (PHPP) was released in 1998 and has been continuously further developed since then. New modules which were important for planning were added later on, including advanced calculations for window parameters, shading, heating load and summer behaviour, cooling and dehumidification demands, cooling load, ventilation for large objects and non-residential buildings, taking into account of renewable energy sources and refurbishment of existing buildings (EnerPHit). The PHPP is continuously being validated and expanded in line with measured values and new findings.

===== Conclusion - More than just an energy balance! =====

The **Passive House Planning Package (PHPP)**  (order [[http://passiv.de/literaturbestellung/index.php/en/?task=view&category_id=1|here]]) is a design tool which enables architects and designers to professionally plan and optimise their Passive House design. The PHPP contains dimensioning tools for windows (with regard to optimal thermal comfort), home ventilation (with regard to optimal air quality with adequate air humidity) and building technology. The PHPP treats the entire building as one unit including the ventilation system and other mechanical systems.
