Change of street lighting
In reply to Tommy,s note.
My son-in-law does energy saving projects for a well known English supermarket.
He says. That the saving on their car park lighting using LED,s
Is 50%.
So there is something wrong with the saving mentioned, or they have installed the wrong type of fitting.
Well I am back again, will my info be correct or is it a dream.
When the LED's were put in place in La Marina Urb. Some one stated that the Electricity would be 10% cheaper, AND that the Company who was supplying the electricity would supply the bulbs and fit them free of charge. In my mind that is the reason for the smaller discounjt, I don't know how long the contract between company and council exists for, But I would gather anyone dealing with a new contract would insist on a bigger Discount next time round.
Probably typical of councils all over. Cost doesn't matter when its someone else's money. It's always a vote winner to be seen to go green. When we had a earth day my local council in the uk duly switched off all the lights for a few mins before re-lighting every office in the block.
Can't beat actual power usage used. There always seems to be percentage savings bandied about. In a previous job I used to do return on investment reports and sometimes projects are difficult to justify.
