Energy Efficient Lab Renovation: A Demonstration
Project that Contributes to a Sustainable Campus Development
Research Centre Juelich, STE
The German Helmholtz society is an association of 15 national research
centres, which are active in the fields of energy, earth and environment,
health, key technologies, structure of matter, transport and space.
One of these centres is the Research Centre Juelich, which has 4,400
employees, of whom about 1,100 are scientists. The campus covers
an area of one square mile and consists of about 80 buildings. The
building stock includes research labs, offices, lecture halls, a
large library and utility buildings. Most of the buildings were
erected in the early seventies and do not meet current energy efficiency
standards. There is a considerable potential for energy savings,
therefore, a demonstration project has been initiated with the objective
of renovating an existing lab in order to reduce energy consumption
by 60%. The project serves as a demonstration project for further
lab renovations of the Helmholtz society.
The renovated lab was built in 1973 and served as a chemistry research
building. The total floor space area amounted to 35,300 square feet.
After the renovation the lab is used for botanical research. Additionally
a large greenhouse has been erected outside. The energy efficient
renovation included a significant improvement to the thermal insulation
of the whole building envelope, modernisation of lighting systems
and a renewal of HVAC systems. A comprehensive thermal measuring
and evaluation programme will be carried out during the next two
years to optimise the whole system. Based on the experiences of
this project, a research laboratory renovation guidebook is under
The lab renovation described here shares commonalties with the
Labs21 Approach, which among other things is related to minimizing
environmental impacts and optimizing whole-building efficiency.
In particular, this project illustrates significant energy savings.
Manfred Kleemann has received his diploma in mechanical
engineering from the Aachen University in Germany. He has written
a dissertation on compact heat exchangers. Since 1973 he works as
scientist and project manager in the Research Centre Juelich. His
research activities focussed on energy and environment studies and
on the assessment of new energy technologies. Since 1996 he is head
of the research group "Energy Supply for Buildings and Renewable
Energies". He gave lessons at the Aachen University in "Optimisation
of Energy Systems" and became in 1998 honorary professor.
