Real automation made real easy
A few years ago, automation was only for HVAC systems and the typical BMS system was just a box of
magic
tricks that no one but the programmer understood. Riddled with line by line programming code
these systems
were expensive to implement, change and maintain.
Today's typical Lighitng automation system is just like this, old technology, complicated,
expensive and
slow.
But not any more. BAS lighting automation is breaking new ground and bringing our
renowned BMS
system into the lighting market. With blistering fast speeds and reliability second to none, as well
as the
highly
sought after Logic Pages, lighting automation becomes real automation made real easy.
What's more, integrate the lighting system with the HVAC system and you have one fully integrated building management system.
This alone has benefits such as:- You only have to deal with one company
- The same system can monitor and control energy
- Easier for end users as they only need to learn to use one system
- No duplication of field devices such as occupancy sensors and after hours buttons
Inifinate functionality
With BAS lighting automation you can achieve virtually anything. And we can implement it quickly and less costly than anyone else. Here is just one example of what we can do:
Each lighting and HVAC zone will be controlled by the adjacent Ultrasonic Occupancy/Light Level Sensor.
During normal hours, the light level will be controlled to 500 lux when occupied and 100 Lux (adjustable for each zone) when unoccupied.
During after hours, staff after hours control will control lights to 500 lux as normal. Cleaners after hours control will control to 350 lux. Staff/Cleaner after hours control via digital keypad or key switches.
Before lights turn off (0%) for un-occupancy the lights level will control to 100 lux for 1 minute and then turn off (0%).
Lighting zones setpoint can be overridden by a global inhibit command based on total building energy use. If total current demand (kw) is exceeding a predetermined threshold lightings zone setpoints will decrease as follows:
Firstly, all common areas such as lobbies and corridors will reduce lux setpoint by 100 lux. If energy demand is still high, the remaining lighting zones will reduce lux setpoint by 50 lux.
This lux relax strategy is part of an overall energy relax strategy which includes HVAC and is to be controlled by the main building BMS. Any zone can be excluded from energy relax via mouse click from the respective graphic page.
The occupancy sensor will be used to activate/de-activate the local HVAC terminal equipment as follows:
Occupancy: Control as normal.
Unoccupied: The terminal unit will revert to a setback setpoint of +/- 1 degree to prevent unnecessary heating or cooling.
Other strategies such as security tour modes, security breaches, power failure (generator supply), generator testing, fire and any other strategies can be easily incorporated in our logic block programming.
Lighting - the way to additional energy savings
Facility managers know that lighting protocols can have a profound impact upon energy use, comfort
and productivity as well. WebCTRL's new LC-line of lighting control panels provides superior lighting
control with complex lighting
management functionality for occupancy control, scheduling, daylight
harvesting and more.
Along with the Environmental Index and Energy Reports, it's one more way BAS can help you lower energy
and operating costs.
Why WebCTRL?
The lighting systems can be fully optimised when integrated with the WebCTRL building management system. Some examples of this:- Use the information of occupancy detectors to switch on the light in each zone only when needed, and at the same time actuate on HVAC setting the heating/aircon in stand-by mode when there is no one and back to comfort mode when there is someone
- Dimming appropriately the luminaries and actuate on window blinds to reach the optimum light level in each zone at any time according to information provided by light level sensors
- Control of lighting from the BMS
- Logging of data for energy consumption calculations
- Automated notifications to maintenance workforce when lights are failing or are about to reach end-of-life.
