Brief

LEDUS were approached by Stanmore College to replace their original CFL lighting, The client indicated that they were interested in changing to LED Lighting with LEDUS due to the LED lighting improved energy efficiency and low maintenance when compared to the existing CFL lighting. The requirements were to change the lghting in a series of classrooms, corridors, a sports hall and an assembly hall.

A survey was undertaken of Stanmore College by LEDUS and an agreement was put in place to replace 156 fittings over 3 stages with an estimated ROI of less than 3 years. The first stage was a full upgrade of the lighting in the sports hall and assembly hall, the second and third stage was for a like for like replacement in the remaining areas of the classrooms, corridors, lobby and other communal areas.

Client Testimony

Why were you looking to change to LED?

I was looking to change to LED lighting due to its improved energy efficiency and low maintenance in comparison with CFL lighting.

How did you hear about LEDUS?

I found LEDUS by searching for lighting suppliers and installers online.

What were your requirements?

I had a number of classrooms and hallways, as well as two large halls, with CFL light fittings that needed to be changed. In total there were probably in the region of around 120 light fittings to be replaced.

Are you happy with the upgraded brightness levels?

The rooms and corridors are noticeably brighter and several students and members of staff have commented on the improved lighting. The halls have also both seen massive improvements in lighting levels, more than double the lighting level in one of the halls.

Are you happy with the outcome?

I am very happy with the outcome.

Have you noticed that the school has started saving on energy costs and lighting maintenance?

In the 9 months since the new LED lighting has been installed we have seen a drop-off in electricity usage of around 18,000 kWh compared to the previous 9 months. Our electricity prices are currently quite high (around 10p per kWh) so we have saved nearly £2,000 in energy usage alone in 9 months. This should give us a return on investment in approximately 6 years and that is not taking into account additional savings from replacement lamps and the savings in maintenance man-hours.

Do you know of any challenges or difficulties, if any, how did LEDUS overcame them?

There were substantial difficulties in the installation in one of our halls due to the layout of the lighting and the features of the hall. LEDUS were fantastic throughout and quickly arranged for an alternative form of access equipment (without any additional cost to the College) and resolved the issue.

What are your overall experiences in working with LEDUS?

LEDUS were excellent throughout the entirety of the project, from initial quotation to completion of the work. They kept me up to date with what was going on and worked quickly to resolve any problems, such as that mentioned above.

Their aftercare has also been brilliant with a follow up call from their Technical Sales Engineer to ensure that everything was okay with the installation.

Would you recommend LEDUS to your contacts?

I would have no hesitation whatsoever in recommending LEDUS to anyone. Would you use LEDUS again if you had the opportunity to? Absolutely. In fact I am in the process of planning another project with them as I write.

Financial Breakdown

Stage 1

The first proposal was to replace 47 Luminairies throughout the sports hall and assembly hall, the total Supply and Install cost was £4,797.95.

Stage 1: ROI

The sports hall and assembly hall areas have a return on investment in 2.15 years

Stage 1: Lifetime Savings

The estimated lifetime of the sports hall and assembly hall installation is 21.65 years, during this time Stanmore College would have spent £64,474 on energy usage, luminairies replacement and maintenance, whilst LED lighting by LEDUS UK reduces this cost to £16,215.00, achieving a lifetime saving of £48,259.55 on their lighting energy and replacement costs.

The college will also reduce their energy usage from 206.65 tonnes of C02 to 69.69 tonnes of C02 producing a total savings of 136.96 tonnes of C02.

Stage 2 and 3

LEDUS proposed to replaced 109 luminairies during stages 2 and 3 which would replace the lighting throughout the entrance, corridors, offices, stairwells and classrooms. The total supply and install cost was £8,886.52.

Stage 2 and 3: ROI

The corridors, classrooms and other communal areas have a ROI of 2.87 years.

Stage 2 and 3: Lifetime Savings

The estimated lifetime of the corridors and classrooms is 18.04 years and under their exisiting lighting Stanmore College would pay £80,470.10, under LEDUS LED lighting this expense is reduced to £24,627.25.

The overall saving on lighting energy and replacement costs is £55,842.85. The C02 consumption is reduced from 218.38 tonnes to 105.85 giving a lifetime C02 reduction of 112.53 tonnes. Want to make your business

Challenges

When carrying out the installation in the sports hall and assembly hall, the installers used specialist protection on the flooring to protect it when using the scaffolding towers and therefore caused no damage to the surface. The installers also had difficulties with getting the access equipment into the Assembly Hall through double doors. A scaffold tower solution was not able to reach certain areas, so a foldable boom lifter(Niftylift) was used which was light enough to move around without damaging the surface, whilst allowing the installers to reach areas normal scaffolding could not access.

Outcome

Sports Hall and Assembly Hall

The Sports Hall and Assembly Hall was completed in 1 stage over the summer holidays when the school was closed . The Sports Hall was completed in 1 day and the Assembly Hall was completed in 2 days.

“The halls have both seen massive improvements in lighting levels, more than double the lighting level in one of the halls.”

The Sports Hall had 32 x 8FT 100W Fluorescent T12 Tubes with a metal protection cage to protect them from the impact of the sporting activities. LEDUS replaced the existing lighting with 32 x 5FT LED Tri Proof 60W in the same location, which saw a 40% reduction on energy usage but with a higher lumen output and higher brightness levels. The Tri Proof light is IP65 Rating with an IK07 Rating to withstand impact resistant from all the different sporting activity being carried out.

In the Assembly Hall, the existing luminaires were 15 x 6FT 4x70W T8 Surface Mounted Panels which were replaced with 15 x 4FT 1200x600 LED Panels with a surface mounted frame, this resulted in an 80% reduction in energy usage but with a higher lumen output and higher brightness levels.

Classrooms, Corridors, Lobby and Communal Areas

Both the second and third stages took 1 day each and during this period the lighting in classrooms, lobby, corridors and other communal was replaced.

To be able to achieve the required lux on the sports floor and assembly floor, LEDUS carried out a Dialux report to confirm that the proposed LED luminaire would be sufficient and provided a simulation drawing of the layout of the upgraded areas.

“The rooms and corridors are noticeably brighter and several students and members of staff have commented on the improved lighting.”
