After Hours HVAC Access and Invoicing

Tenants use the Building Services Panel to control the turning on and turning off lighting and air conditioning according to pre-defined time zones.

With the use of a Building Services Control Station (BSCS) authorized card holders can request lights and/or air conditioning to be turned on "after hours." Typically, lights and air conditioning for suites, offices, floors, or areas are turned on automatically during normal business hours, with this cost included in the lease.

The BSCS is the device that authorized cardholders can request lights or air conditioning "after hours". These panels are typically placed at central locations, accessible by all authorized cardholders, and often there is one per floor, or at the guard station or security office. An authorized cardholder can turn on lights only, air only, or both. In addition, the cardholder may cancel requests. The device has a display for instructions, and the keys are marked for easy use.

The BSCS is used to make and cancel requests. Requests for lights and/or air conditioning can be made in full hour increments only.

There are two types of requests, instant and delayed. When you make an "instant" request, a timer is started for that request. After 1-minute mark has passed, you will be billed for the entire hour, even if you cancel the request 2 minutes after you made the request. The other type of request is the "delayed" request. This type of request is made while still inside the time zone associated with the lights or air. In other words, they're still on. Let's say it's 3 o'clock in the afternoon. The lights normally go off at 6 PM., but you know you'll be working later than that. Rather than have the lights go off at 6 and walking out to the BSCS to request additional time, you can make your request in advance. The system remembers your request and when 6 o'clock rolls around, your request is automatically invoked and the lights stay on. There will also be times when several cardholders from the same suite make "advance" requests, each unaware that the others have also made advance requests.
