Energy policy lighting EfficiencyWasting energy during the daylight hours

It is a bright summer day, but the external lighting burning, that is an excellent demonstration of the actual energy and environmental policy in action.

Profligate energy waste is common, practically an epidemic in cities, but it need not be.

Missing Code

Wasting energy is unforgivable, and demonstrates the lack of imagination of designers, digital switches, and failed building automation systems also called building management systems.

And let's be clear, it's not rocket science, the building interface must match the needs of the users, the latest digital time switches are not intuitive or user friendly.

If we take a step back, in the past the building staff took care of the building including tasks such as adjusting time clocks, etc. Then, to save costs, employees were replaced by sub-contractors whose staff were often not familar with the installed plant nor the complex digital timeclocks installed.

I don't advocate a return to the good old days, I do advocate for smarter thinking, for buildings with a building automation system with a few lines of extra code could help cure an epedemic.

pseudo code:
888 IF daylight outside = TRUE
889 AND external lighting amps > 0
890 THEN raise fault condition
891 AND switch OFF external lighting
892 END IF

We need smarter thinking to achieve smarter and more energy efficient buildings.
