energy saving

[Steve]

So come on, what energy saving/automation initiatives have the sparks on here seen/fitted/done?

I saw one today, the WHS in Doncaster has had one tube in every fitting removed/disabled. This has reduced their lighting bill by a third.

In my shop the lighting is controlled by "adam international" via a set of dial-up relays.

Anything unusual you've seen?

Perhaps if they remove all the tubes, they will be able to reduce their bill by 100%?

Indeed but then they'd have to reduce their income by 100% too and the books would never balance.

Hi Steve,

Appreciate your enthusiasm, but probably best not to discuss company details so intimately on a public forum.

Cheers.

Tim.

It's not like he's told us the address of the shop and the combination for the safe

at my place they didnt turn the steam heating on this winter, saved over £300,000. The unions where not too happy mind, although the inside temp was still above legal minimum.

we also have replaced all compressed air sump pumps ( all grey water flows to huge sumps which then get pumped to a central sump for treatment before going to sewers) with high efficiency motor driven centrifugal pumps on inverter drives which alter pump pressure depending on demand

also, certain wash water from some manufacturing vessels is passed through secondary heat exchangers before going to the sumps, to trace heat HW pipework.

the 3 large vacuum pumps we had have all been condemned and production areas or lines requiring vacuum now have their own local vac pump which they reckon has saved £25000 a year on leccy.

bear in mind our companies combined energy bill for steam, air, water and electric is over 1.8 million pounds a year

If that sort of stuff counts, the company where I work kept the temperature to between 9 - 13 degrees celcius throughout most of the winter. Their energy saving strategy is not to fix any of the broken overhead radiant heaters, thus saving on parts, labour and gas

Air and steam leaks must be biggest waste of power and even when I started over 30 years ago firms would have a purge at reducing leaks and removing redundant pipework.

During one of these we found a steam pipe and SWA cable which lead of in the direction of local housing estate we guessed to some unused well as the process used a lot of water and wells had been sunk all around the site.

However it transpired it went into one of the houses and on enquiry it was found the old electrical engineer use to live there before his death.

The widow when asked about her electric and heating bills say how her husband had sorted all that out before his death. Well that was true. The management decided a court case would be counter productive and so she was give some time to get central heating installed and electric re-connected then it was removed.

Couldn't see her getting away so lightly now.

However many HF florescent units will be damaged by removing tubes and the idea of using methods like that must be flawed.

In one place I worked one of the boilers failed so the offices became colder for about 8 weeks while work was completed to replace it. On the attendance chart which showed how many off sick there was a corresponding dip. May have had nothing to do with cooler offices but when ever cost cutting measures are taken that effects workers comfort it is likely production will suffer as a result.

So remove tubes and then you find every desk has a desk light. When working in one retail outlet we were instructed no more that 2 foot between lights as the research had shown how the got more sales when shop was very well lit. As a result they needed 7 x 9KVA air conditioning units on the roof.

It seemed that in most places the original building would be raised to the ground and re-build with all the energy saving that could be included but because it was in Chester they were not allowed to do this.

Seen some mistakes too. The compressors were fitted inside the building so the heat would warm the building. However the number of times a fork lift managed to damage them and stop production outside would have been better. Then forklift operators would have been more likely to hear instructions.

yes your right eric, HF fittings with one tube removed actually shortens the lifespan of the fitting. Did you also know that you should not fit HF fittings on the same circuit as old ballasts?

our management wanted one tube from every double fitting removed, until we showed them the results of our tests.

 

[333rocky333]

Regarding H/F twin fittings.
I have yet to see one where you can remove one tube and the other stays on.

 

[bhm1712]

you have not seen too many then!!

tridonic we use at our place, and you can remove one tube and it still works...

 

[333rocky333]

We maintain one company who has over 100 thousand nationwide, all with Tridonic PC258 ballasts.
Wired to wireless motion sensors.

Never seen a Tridonic fitting though,do you have a part number.
Would like to see one if possible.
We have lots of issues where when one lamp or the unit fails, both lamps go out, which is inconvenient, but cannot source any with 2 single units in.

OOI, What was the result, please.
