World Sustainable Energy Days

Johan Cristol from Passive House Institute and Magdalena Hajdukiewicz from National University of Ireland Galway presented Built2Spec at the World Sustainable Energy Days taking place in March 2017 in Wels, Austria.

Passive House Institute demonstrated the methodology for the export of BIM data into the Passive House Planning Package PHPP.

PHPP is an easy to use planning tool for energy efficiency for the use of architects and planning experts. The reliability of the calculation results and ease of use of this planning tool has already been experienced by several thousand users.

PHPP provides reliable results such as the heating demand per year [kWh/(m²a)] and maximum heating load [W/m²], the cooling demand per year [kWh/(m²a)] and maximum cooling load [W/m²] (in case of active cooling) and the assessment of the annual renewable energy gains [kWh/(m²ground a)].

Passive House Institute is investigating how BIM can be integrated into the Passive House design and quality assurance process and how required data for PHPP energy calculations can be directly extracted from BIM models into the PHPP.


NUI Galway presented their paper “Metholodolgy of quality checks for energy efficient buildings” giving an overview of Built2Spec with special focus on the methodology for the use of sensor-embedded construction elements for continous self-inspection and quality checks in energy efficient buildings.
