Options of integral planning
Complex, optimized solutions
usually require a similar optimized planning process. There is unfortunately no way round
it. This causes an expenditure of
time and planning costs which has previously been avoided by the operators of
food markets. This is understandable, as
it is not their core business. Here a neutrally moderated planning process
becomes a necessity. All experiences, concerns, and anticipated
problems have to be brought together. For this an integrated planning approach is
unavoidable. We would describe the word „integrated“ as an
increasingly refinded evolutionary process which includes all those involved in
the project. The
quality of the process results from continued coordination. The unpopular
conflicts with all sorts of „worriers“ are an essential part of the process which
generates a result suitable for everyday use.
Often the central problem of
the process is lack of motivation and the willingness to
cooperate among all those involved in the project.
According to the policy of the respective operators, there are „TGA-court suppliers“, which are easy to motivate during the
process, but also competing manufacturers of TGA-components, with whom an
integral working relationship is difficult or even
impossible. The necessary expenditure of time for this may not be underestimated!
There are many intelligent ideas for concepts: Only by further development and
adjustments, a convincing, building concept which is suitable
for everyday use can be created. Unfortunately on the part of the
operators, performance-related remuneration of necessary performed planning and
coordination work is often not fulfilled. This results
in shortsighted and inconsistent solutions which soon cannot satisfy
the ever-increasing demands anymore.
The best example of successful Integral planning
is our coordination work for a food discounter in Northern Germany. Thanks to a continuous consultation process which lasted 18 months, a perfectly fitted pilot project could be
realized with the help of all involved. Just in time before
the EnEV 2012, a production model suitable to any
territory could be completed. This May, two slightly
different prototypes will be built under realistic
conditions and metrologically inspected during the winter of
time for the the next stage of increasing
requiremets, a coordinated, tested project is ready for nationwide allocation to building companies. This was also based on a
regular bimonthly process of coordination of planning, in which concepts and
solutions gradually evolved.
Two technology concepts are going to dominate
the development of future retail trade buildings
Air heating and radiant heating differ due to the temperature levels of the heating systems:
The thus far, mainly used air heating at a temperature
of about 55 to 70 degrees Celsius, and the industrial
floor heating at a temperature of about 30 to 35 degrees Celsius.
Both systems also have cooling capacities, whereas the low-temperature solution
seems to be technologically more efficient für the
majority of the future possibilities of use. In the
field of restoration work however, low-temperature
solutions are hardly ever realizable due to the lack of large heating surfaces.
Very promising are - suited to high
demands – complex air heatings with heat pump technology, for example the VRF-technology
by DAIKIN. We must not overlook the following: A great
potential is hidden in the thoughtful retrofitting
of older supermarkets. newly gained knowledge from new
buildings must influence the retrofitting of the older buildings. However, in
almost all cases, individual planning and coordination is necessary. There are no „nostrums“ in building renovation.
In May 2011, this article will be published in the
following two trade journals:
Kälte & Klimatechnik
Monthly German-language technical magazine for
professionals in the area of commercial refrigeration and air conditioning
systems. Readers are engineers, technicians and installers of
such systems in large commercial environments such as supermarkets, breweries,
and other industries where refrigeration and cooling are basic to their
business. Subjects covered include handling technology, research,
applications, controls and systems maintenance, energy savings and
A periodic specialist magazine covering technology for
the energy of the future. The purpose of Energy 2.0 is to supply up-to-date
information about technologies that will guarantee our energy supply in future.
The readership comprises decision-makers on general management level as
well as energy-relevant areas: general management, technical management, energy
management, energy and environment representatives, facility management,
production management, engineers, technicians and fitters.
Most innovative trade journal of the year 2010. http://www.energy20.net/pi/index.php?StoryID=917
