Passive House Consulting with Certification
Project Control System for Energy Efficiency
Definition Consulting:
To give special knowhow in existing teams of designers and builders, often winners of
an architectural competition, to ensure the certification standard very early and in an
economic way !
PH-Consulters usually are charged by the investor, as one of the main team members,
not in charge with architecture or standard engineering.

Passive House Focus:
Architecture and Variety of Facades
To reach Passivhaus Standard is a lot easier with large and compact
buildings than with smaler ones !
Freiheiten in der Architektur, Gestaltung sind grundsätzlich möglich und gefährden die Wirtschaftlichkeit langfristig gesehen nicht, das zeigte zuletzt der Passivhaus Award 2014. Im Maße wie die
Freiheiten genutzt werden, gehen die Anforderungen an die vorhandenen Grenzen.
Fassaden treten bei großen Gebäuden immer mehr in der Focus der Effizienz- und langfristigen
Wirtschaftlichkeitsbetrachtung, besonders dann wenn es um die Sommertauglichkeit und damit den
Komfort mit notwendigem Kühlbedarf und der Nutzung natürlichen Lichts geht !

PHPP 9 - IHG in Residential Buildings

PHPP 9 - what is new ?
New in PHPP 9
Hinweise
new PH-classes:
• PH-classic, PH-Plus, PH-Premium
• new PER-factors: renewable primary energy
• consideration of renewable energy production
• old certification system always
available/valid
• PHs with old criteria are not
automatically PHs according to the
new ones
internal gains in residential buildings now
depend on the TFA per dwelling unit
huge influence on Qh
positive for small dwelling units
more accurate calculation of DHW
more accurate results for nonresidential buildings
better integration of the different climate zones
(cold, warm, humid, etc.)
more accurate results for cooling
and dehumidifying
sheets for variants - comparison - control
risks of mistakes - confusing ? needs getting used to
97
Passive House: Results and Guidelines
Passivhaus needs
straight ways to calculate energy efficiency ((PHPP)
integrated experience in practice, after training (CEPH,….)
sustainable architecture, integrated design, quality management
convinced designers, craftsmen and better products,
straight promotion in a jungle of diverse arguments (LEED,…)
certification to become passive house the standard, not somehow
Passivhaus is not cost neutral in the investment, as long as the
regular standards and quality management for energy efficiency
are lower, but it is economic from the first day using it, because of
more comfort, more and long lasting building quality, lowest
energy costs, now and in the future, in summary more value at
all !!
