Staccato Shoe Shop, York

ENERY SAVINGS

York-based company Pavers Shoes, who have over 88 stores in the UK and Eire decided to trial the LEC in their high fashion stand alone outlet, Staccato at McArthur Glen Designer Outlet.

 

The survey of the lighting circuits indicated that the power consumption was nearly 10 kW. As the store utilised a mix of lamp types we installed a LEC A which was capable of dropping the voltage by up to 35V and stabilising at the set level. The estimate was for a reduction in the lighting bill by at least 20%. In addition, the air conditioning bill was forecast to come down due to less heat being generated by the lighting. The total direct saving from the installation of the LEC was projected to be nearly £100 per month.

 

An additional benefit of installing a LEC is increased lamp life due to running at lower voltage. The savings in maintenance costs were expected to be at least £50 a month.

 

Savings reported by Pavers following the installation:

 

Month	Total Monthly Bill	Cost Per Day
July	£362	£11.70
August	£292	£9.70
September	£195	£6.50

 

Jim Young, Facilities Manager - Pavers Shoes commented: “The LEC offers a win-win situation for Pavers Shoes, enabling us to reduce our carbon footprint at the same time as cutting our electricity costs. Another very important cost saving for us will be extended lamp life, with typically £250 per month being spent on new lamp installations at the York Staccato store alone.  I am looking forward to rolling this out to our other stores across the UK”.

 

Technical details

Prior to the installation, an energy monitor was installed. The daily power consumption with half-hourly data was transmitted via a GSM link to a website. This allowed tracking of the savings without having to visit the site.

 

The hours of operation of the shop are from 8.30am to 6pm, seven days a week. The energy monitor recorded the higher consumption during the opening hours, but also showed that there was significant power usage overnight at the rate of 5kW.

 

The LEC was installed at the end of July. The lighting circuits were separated from the other circuits and routed to a new distribution board connected to the LEC. There is a built in bypass feature, which makes it easy to switch the LEC in and out of circuit.

 

Post installation measurements showed that the power taken by the lighting circuits was reduced from 9.5 kW to 7.5 kW by the use of the LEC. This represents a saving of just over 20%.

 

The air-conditioning timer was re-programmed to reduce power consumption overnight. This and the reduction due to lower heat generated by the lamps led to a much improved energy profile.
