Asset management in office

spaces and hotels

Building space is an extremely expensive

resource, costing up to several 100 euros per

square meter per month. However, less than

70% of many spaces is used, such as office

working areas, hotel rooms, conference

rooms, cafeterias, hallways and storage

rooms. As a result, running expenses in the

millions are unnecessarily incurred for heat-

ing, lighting and maintenance. Existing hotel

rooms can be upgraded without problems

with the aid of wireless sensors without

impairing normal building operation, which

reduces energy consumption by 30% to

40%.

Suitable sensors can be used to prepare the

use pattern for the building, personnel and

inventory: presence detectors in the room or

at individual seats; door contacts; sensors

for counting people; power meters for

detecting the activity of electronic devices

(such as printers, copiers, soap dispensers,

coffee machines, electric kettles, ventilation

units). Cyclically transmitting sensors,

so-called “beacons” are used to determine

the locations of mobile devices and furni-

ture. If the capacity of company facilities is

only partially utilized, for example, combin-

ing multiple sites can help reduce costs. And

if the building system determines that no

employees enter the building before 8:00

am, the heating times can be adjusted

accordingly.

Sanitary facility management

It is practically impossible to forecast the

optimum maintenance and cleaning of sani-

tary facilities in office buildings according to

their actual use. For example, toilets are

often not cleaned when needed, and paper

and soap dispensers are empty, which is

frustrating for users. Simple monitoring of

sanitary facilities with presence sensors

makes it possible to efficiently clean the

areas and plan resources, which, in turn

substantially lowers costs and increases

user satisfaction. Read more about this topic

on page 12.

Analyzing the use and

determining the location of

devices and furniture

Current sensors in the supply line enable the

use of electronic devices in a building to be

evaluated. To analyze capacity utilization, a

power meter located either in the power

cable or the plug transmits the device’s cur-

rent status. Wireless beacons are used to

determine the location of mobile objects. An

integrated temperature and humidity sensor

can also supply the ambient conditions of

the inventory. To determine the location, the

wireless gateway infrastructure analyses the

beacon’s signal strength. Electrical and elec-

tronic devices can also be turned on and off

with the aid of presence sensors in order to

thereby optimize the service life and energy

consumption.

Monitoring buildings for

insurance companies

Insurance companies incur costs in the bil-

lions every year due to the late detection of

events such as water leaks, fire damage and

building break-ins. This, in turn, is reflected

in the constantly rising insurance premiums.

In the event of flooding, fire or intrusion,

EnOcean-based sensors supply in real time

the data and information needed to alert the

owner and the insurance company. Serious

and cost-intensive incidents can thus be

detected early on and resolved accordingly.

Sales areas and gastronomy

When it comes to sales and commercial

space, the flow of customers correlates with

staff requirements, sales figures and location

attractiveness. Smart data analysis makes it

possible to distribute sales personnel

resources according to need and also pro-

vide an indication of any improvements that

may be needed to areas where sales are

weak. Presence detectors supply detailed

information on parameters such as move-

ment profiles, number of people and table

occupancy. A call button on the restaurant

table or at special sales kiosks, which can be

used to request a waiter or sales person, can

help increase customer satisfaction, for

example. Small animal traps, which can be

immediately emptied via special sensors as

needed according to legal requirements, are

also relevant.

Parking space management

Another important application in buildings is

the monitoring of parking space. Pressure

sensors, installed in the ground, detect the

direction of vehicle travel and thus also the

occupancy of parking spaces.

Maintenance of motors, gears

and brakes

Facility managers generally prefer detecting

down times early on, since preventive main-

tenance is always associated with high costs.
