FertighausWelt Cologne PEH as single family detached homes
sustainable prefabricated timber structure
energy efficient building envelope
priority: energy saving first, energy production second
heat generation by electric power only
ventilation systems with heat recovery are mandatory
long term monitoring of the energy footprint

Officially approved PEH have been made ready for the market
PEH standard allows wide variety of architecture = competitive advantage over restrictive standards, e.g. „Passivhaus“. Reasonable energy surplus 10 % - 30%
PEH detached homes – first results
Required components:
solar power generator (8,5 - 14,5 kWp) heat pump with high level conversion efficiency ventilation system with energy recovery
Optional components:
energy storage intuitive visual controls e-mobility
FertighausWelt Wuppertal PEH as a smart residential quarter
sustainable prefabricated timber structures
unlimited individual architecture
next steps:
interconnection by shared fiber optics infrastructure
shared high-capacity battery storage
monitoring and visualization of energy budget
common e-mobility solution
connected to public power grid
Smart residential quarter features
