Company profile
Hottgenroth Software offers a wide
variety of modern software solutions
and a customer-oriented range of
services. Our products cover among
others energy-efficiency-software and
a set of building-services-software.
From 2009 we also actively participate
in the program of the German Federal
Ministry of Economics and Technology
“Energy Efficiency made in Germany”
(http://www.efficiency-from-germany.
info/EIE/Navigation/EN/root.html).
The company was founded by Karl-
Heinz Hottgenroth. At the end of the
90's he promoted the development
of the Energy Consultant which is the
2
leader in software for energy consultants
in Germany. It is an essential tool
for architects, building engineers and
craftsmen when it comes to renovation
of existing buildings or designing of
new, energy efficient buildings.
In 2002 ETU Software and Hottgenroth
Software became partners. As a result
the product portfolio was extended
by building-services-software. In
2005 ETU developed a product-dataentry-software,
especially for industrial
customers and manufacturers.
Nowadays is Hottgenroth Software a
successful development, controlling,
distribution and customer service
team. Programming and support are
provided by a high-class pool of qualified
engineers, physicist and computer
scientists in close collaboration with
experts in various trades.
The in-house support team is continuously
strengthened and technically
enhanced. At the moment the hotlineservice
team consists of more than
20 certified energy consultants for
buildings.
They assist fast and uncomplicated;
the experienced employees keep
records of conversations and give
suggestions to the development team.
The customers thus profit with each
software update they regularly recei-
ve. Distribution of hardware, technical
support, training courses and internet
offers complete the company's range.
Hottgenroth Software attaches great
importance to quality, concerning both
product development and working
process. Certification of internal quality
management demands a great deal of
all employees. Internal training courses
guarantee continuous qualification of
our team.
Our highest priority is, in addition to
software service and optimisation, the
market-oriented strategic development
of our products. We are now looking to
apply our technology to new markets,
new instruments and new applications.

i BUIlDING SIMUlATION
With the ETU/Hottgenroth advanced Building Simulation, the planner and creator can simulate the behavior of a building
with hands-on user profiles and environmental factors. What cooling-loads and which heating-loads occur in the various
”user zones”? What diurnal profiles do the individual rooms and zones have, how do people and activities impact and
what different types of windows and building materials can affect the cooling-loads? Solve these issues with the Building
Simulation and make even the preliminary planning for a consultation.
