IS &C core standalone applications: presence detection

Infrared detectors trigger lights when people are present or passing by

Hotel applications :• Integrate between presence sensors with door lock

by wireless communications , and accurately detect the absence of hotel guest to implement energy saving mode ( reduce cooling and lighting )

A whole building does not need to run on 100% comfort setting if only a few occupants are in a given area!

Zone schedulingAllows defined sections of a building to have lighting reduced or shut down on a daily / monthly / yearly schedule

While the initial costs of basic controls are lower, the building owner’s ability to more aggressively manage energy is compromised by low-cost, fixed-function solutions...

The common feature among all top performers is superior energy management at the building level

To maximize savings, combine your energy efficiency applications at the building level!

Overall energy saving of up to 60% through appropriate control at the building level is achievable!

40% to 60%

From standalone to integrated systems consolidated gains at the building level
