Premino II - Self-powered wireless in commercial building automation

Intelligent building automation systems have been deployed in a Munich-based commercial property called Premino II to emphasise the building's attractiveness and economic value to tenants. The use of EnOcean self-powered wireless technology minimised planning efforts and reduced the amount of cabling required during installation[...]

The EnOcean easyfit wireless switch is fitted to a variety of surfaces, such as glass, wood or furniture, throughout the building to control shutters and to enable lighting to be switched and dimmed wirelessly as necessary. Grouped lighting effects are easily created at any time directly from the PC.

For temperature control, an EnOcean enabled solar-powered room temperature sensor detects the deviation from a given figure at regular set intervals (>15s). Only if the figure deviates is the information sent to the automation, where it is used to control radiators and integrated ceiling cooling. The user can match the room temperature to individual requirements within preprogrammed limits.

Solar-powered wireless window contacts from EnOcean (enabling operation in complete darkness for as long as 70 hours) detect the opening of windows and reduce heating in that area, or even cut it out entirely. The heating does not come on again until windows are closed or room temperature sensors detect a lower chill limit.

The use of EnOcean wireless technology in Premino II has enabled tenants to create their own flexible room arrangement.
