Often, more must be done than merely adding or removing components (CFCs).
If, an HVAC device, e.g., is to be added, the following must be added or
removed:
● Information in the operating mode table
● Corresponding BACnet objects to operate the new device
Shading control
Suitable façade products and intelligent control allow for optimum satisfaction
of various requirements for shading.
Façade products and their control required to protect against environmental
influences or to make use of the same are the primary issue:
● Shading to protect against glare
● Using daylight
● Using solar energy for heating
● Shading to protect against overheating
● Protection against rain
Other requirements may be:
● Intrusion protection
● Protection of privacy
Façade product control in addition must protect persons and equipment against
the façade products themselves. Examples:
● Drive up blinds in case of fire to open an escape route
● Protect against collision (e.g., in the event of outward-opening doors)
Façade control protects the façade products and their functionality against
environmental damages caused, e.g., by rain, wind, or frost.
The market knows many different façade products such as roller shutters,
blinds, awnings, etc. to satisfy the various requirements. The different
properties of the products are included in the respective control functions. The
following figure shows a few typical façade products (from left to right):
● Horizontal blinds
● Roller shutter
● Vertical blinds
● Drop-arm awning
● Vertical awning
● Sliding-arm awning
