3.2.4 Cycle operation module (Energy efficiency module)
Advantages:
– Tremendous potential to save electricity by reducing zone pump operation: up to
60% savings in electricity is possible.
– Efficient use of natural and less-expensive energy sources.
Buildings featuring TABS offer energy efficient operation by design, and energy
efficiency is the focus of tested (and proven) DESIGO applications. The TABS
control application with its patented process, including the cycle operation modules
allow TABS buildings to achieve even greater energy savings.
For heating, zone pump runtimes can be dramatically reduced by charging the
concrete core using a slightly higher flow temperature during cycle operation.
The same applies to cooling. Electricity use by zone pumps can be reduced by up
to 60%.
In addition to reducing pump energy, cycle operation can also "position" the switch
on phases to take advantage of energy-efficient or less expensive sources of heat
or cold including
– Using free re-cooling during the night.
– Using heat pump operation at low-cost nighttime rates.
3.2.5 Additional functions
There are numerous additional functions supported by TABS:
– Modular designed standard library applications including graphics for plant
operation (using DESIGO INSIGHT to visualize and operate the TABS building).
– TABS building control using various plant configurations.
– Fault shut down to maximum plant and life safety.
– Trending and monitoring for heat/cold consumers and room data.
