Integrated planning approach for HVAC systems
Demand-based control at PUMAVision headquarters in Herzogenaurach
In the new PUMA headquarters in Herzogenaurach, Germany, all electricity comes from
renewable energy sources; HVAC systems are operated based on the demand in each
building or room; lights are turned off when there is sufficient daylight or the room is
unoccupied. A sophisticated building automation concept designed by Desigo system
house IPM – Innovatives Projektmanagement für Gebäudeleittechnik GmbH in nearby
Feucht forms the basis for this high level of building efficiency.
Sustainable construction has become a major trend. Sportlifestyle company PUMA claims to have
built the first climate-neutral corporate headquarters in its industry. The company's new
PUMAVision Headquarters uses not only innovative HVAC technology with thermally activated
concrete slabs, façade-oriented fan coils, district heating, switchable heat pumps for heating and
cooling, partial air conditioning systems and individual-room controllers, but also electricity from
several renewable energy sources: electricity from Lichtblick AG in Hamburg, from a 1,000 m
2
photovoltaic installation on the roof of the Retail building, another 140 m
2
of photovoltaic modules
incorporated into the façades as well as a wind farm in Turkey as a carbon offset project. The
PUMAVision Headquarters consists of three buildings: Office (administration building), Brand
Center (company conference center) and Retail Building (PUMA Store).
Control experts actively involved
To use the renewably generated electricity as efficiently as possible, HVAC and electrical planners
as well as control experts from IPM, a solution partner of the Siemens Building Technologies
division, cooperated closely from the beginning of the planning phase. Experience has shown that
the overall energy efficiency of a building largely depends on the size of the heating/cooling
generators, the hydraulic components, the subdivision of the control loops and interdisciplinary
interfaces, for instance to lighting and sun protection. IPM control experts also contributed to the
design of the hydraulic system since the concrete core temperature control deployed in the
administration building poses challenges as far as hydraulic and control technology is concerned.
