The building automation and control functions described in sections 4.1 and 4.2 are aligned in
accordance with the energy demand and supply model. The relevant energy efficiency functions are
handled starting with the room via distribution up to generation.
The following graphic show the cross-dependencies between functions in the room (e.g. Heating 1.1,
Cooling 2.1) and functions of the distribution and generation for heating, cooling, ventilation and hot
water (e.g. heat pump 1.7, ventilation plant 4.5). To complete the picture also functions of the
Technical Building Management (TBM) and the Building Automation and Controls Systems (BACS)
are shown. The numbering corresponds with the functions described in chapter 4.1 and the energy-
efficiency classifications listed in chapter 4.2.

The following Figures illustrate basic system designs for heating, domestic hot water, cooling,
ventilation and air conditioning purposes. The numbers refer to the control functions summarized in
Table 4. These basic elements can be combined to more or less complex systems that also account
for local, regional or national specifics. The building automation and control functions defined in
Table 4 are according to these basic system designs. Air side system control of HVAC shall be
treated as ventilation and air-conditioning control, separately from heat generators, chillers, terminal
units and water and refrigerant side controls.
