Sophisticated modelling software for real-world accuracy

A clear understanding of the calculations and predictions involved in low-energy building relies upon the use of accurate modelling software. Based on dynamic thermal simulations validated by data gathered from hundreds of low-energy buildings, the German Passive House Planning Package (PHPP) is the software we use to calculate energy use and CO₂ emissions. PHPP's level of sophistication enables it to take into account a wide range of variable characteristics which affect heat loss and subsequent energy use, allowing for a superior fit between predicted energy use and real-world performance.

Suitable for both residential and many non-residential applications, PHPP is supported by an AECB training course to help you get the most from this software.

Order the English-language version of PHPP from the AECB online or by post.
