How much energy does all this consume per year, and also how many tons of CO2 does it produce? We are talking millions of tons of CO2!<P> So what is being done within this segment to reduce energy and improve its effects on the environment? Main lamp manufacturers are developing new and efficient lamps, however the rate of new installations for public lighting is approximately 3% every year. This means it will take at least one generation to see all luminaires changed to the latest lamp technology. There is another solution, a power controller that can be retrofitted into existing street lighting columns. <P> Gitronica, a member of the iGuzzini group of companies, has developed a piece of hardware called 'W-Saver', short for watt saver, that enables a local authority or end user to personalise the output of its lighting. In simple terms, it dims the lighting and reduces the wattage consumed during periods when the need for maximum lighting output is not required.<P> There are many devices on the market that allow us to dim luminaires within the home or in the office when varying tasks dictate that we do not require 100% output from the light fixture, but up until recently, there have been no such products available for external public lighting. External lighting levels are normally calculated on peak traffic flows, for example rush hour, which on a winter's night is maybe between 16.30 and 19.30 hours. But what about 3.00am, when the traffic flow is minimal. Do we still require the luminaire to be running at 100% output? The probable answer is no, and this is where the W-Saver device comes into its own, as it enables the user to step down the illumination level in incremental steps (up to 4 steps) at given, pre-programmed stages. <P> Different personalised programme settings can be made for varying applications. For example a long term car park at an airport can reduce its lighting level by 40% in one step, perhaps 1 hour after the last flight arrival for the night. Town centres and pedestrian areas, in the winter, may want to have the lighting level set at 70% when the lighting is activated in the afternoon, and then at 19.30 increase the output to 100% as the volume of people increases during the evening, and then at 1.00am it could be reduced to 70%, and then finally 60% at 2.00am.<P> The W-Saver unit is installed easily into lighting columns, and can be pre-programmed at the Gitronica factory to the personalised settings required, the programme can be changed after installation if required.<P> It has an internal annual calendar and 5 different levels of output, obtaining energy savings of up to 48% at the minimum level. You can also set 8 special days per month where the lighting requirement may be different to the normal pre-set daily programme. <P> Gitronica Guzzini utilise a bespoke software package which allows one to enter the number of luminaires on a street, enter the chosen programme, and then calculate the reduction in energy, the actual cost saving in electricity used, and also the reduction in weight of CO2 emissions. From a financial perspective, payback (cost of hardware and installation cost) can be achieved within 18 months. <P> Local authorities have now been tasked by Central Government to reduce CO2 emissions by up to 30%, and W Saver can assist substantially in achieving this target from day one. <P> <a href=http://www.iguzzini.co.uk target=resource window><font color=962422> www.iguzzini.co.uk </a> <P>&nbsp;<P> </TD></TR></TABLE> <TABLE height=75 width=600 BORDER=0 bordercolor=000000 CELLSPACING=0 CELLPADDING=3> <TR><TD valign=top align=center bgcolor=E5EAEF> <a href=http://www.thearcshow.com target=resource window><img border=0 src=logo2.gif></a> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href=http://switchedonlondon.com target=resource window><img border=0 width=250 src=SwitchedONLogo.jpg></a> </TD></TR></TABLE><P> </TD></TR></TABLE> </BODY></HTML>
