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
Products and requirements
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
