The [PHPP] (**P**assive **H**ouse **P**lanning **P**ackage) is an indispensable design tool for planning Passive Houses. Since its first publication in 1998 the software has been developed continuously in order to fulfil the increasing demand for more complex specifications. The software was originally developed with a focus of optimising the energy efficiency of residential buildings in cool-temperate climates where the space heating demand is dominant and summer comfort is less of a concern. In this context it has proved its worth in thousands of successful building projects. Meanwhile, the Passive House concept is also being applied in hotter and more humid climates, where the energy demand for cooling becomes more important than space heating. Though the PHPP V7(2012) and earlier do include calculation algorithms for cooling, these were never systematically checked for reliability. | The [PHPP] (**P**assive **H**ouse **P**lanning **P**ackage) is an indispensable design tool for planning Passive Houses.

Recent projects in Mexico in collaboration with GIZ / GOPA were thus taken as an opportunity to review the PHPP algorithms for active cooling in hot and humid climates. The aim was to develop a new and reliable energy calculation tool for Mexico (DEEVi, based on PHPP algorithms).

In climates in which the Passive House concept can be reached without the need for active cooling the frequency of overheating is used as an indicator to assess summer comfort. Though the corresponding algorithms were also updated in the context of the DEEVi developments and thus in the newest PHPP release, this aspect shall not be part of the report at hand. | In climates in which the Passive House concept can be reached without the need for active cooling the frequency of overheating is used as an indicator to assess summer comfort.
