1.1 Executive Summary

Harlan Labs, Wyton requested EECO2 to review the existing lighting at site and come up with a proposal

for upgrading the existing T8 Fluorescent light fittings to new energy efficient fittings in recognition of

increased policy compliance legislation, operational cost optimisation and a continuing business driver to

deliver improved building operational performance.

This Follows the European ban of certain types of incandescent light bulbs; fluorescent tube lighting has

now come under review. Standard T8 fluorescent tubes are being phased out, with production being

halted and the importation of them being banned as part of the EU’s Energy-Related Product (ErP)

Directive designed to reduce CO2 emissions across Europe.

Harlan Labs, Wyton had carried out a lighting audit earlier in order to review the efficiency of the existing

lighting system with a view to make a strategic investment to comply with current / future legislation and

also to reduce energy consumption at site.

The entire site was surveyed in order to review the lighting installation at site, access to the barriers was

made available and have been included in the assessment.

Based on the calculations it would appear that there is an energy reduction figure of 64% reduction in

lighting energy due to conversion from fluorescent light fittings to LED lighting. Lighting accounts for

nearly 70% of the total site electrical consumption, thus energy savings made would be substantial.

Analysis of the survey results confirms that savings of £115,158.84 could be achieved over 5 years for an

investment of £68,885, a payback just over three years.

EECO2 are accredited with the Carbon Trust and Siemens Financial services and can provide third party

funding towards carrying out the energy efficiency project, if required.

Energy Efficient lighting also reduce the amount of internal gains thereby reducing cooling energy at site.

The site is looking at adding cooling in order to meet regulatory compliance, this lighting upgrade would

result in reducing the size of the proposed new cooling plant, thereby reducing initial CAPEX needed

including reduced operational costs.

1.2 LED Proposal

Due to the recent change in legislation following the European ban of certain types of incandescent light

bulbs. Standard T8 fluorescent tubes are being phased out, with production being phased out and the

importation of them being banned as part of the EU’s Energy-Related Product (ErP) Directive designed to

reduce CO2 emissions across Europe.

A desktop exercise was carried out to carry out a retrofit to replace the existing light fittings with Ultra

low energy LED light fittings (30w). A Dialux program could not be carried out due to lack of scaled site

drawings. LED lighting are increasing being used in animal care facilities, cleanroom environment with

good results, and are in fact desirable due to reduced mean time between failure (MTBF) and reduced

maintenance requirement.

The site has been divided into the Office areas and the production areas based on hours of working.

Office areas have been calculated based on an 8-6 PM operation while the barriers have been calculated

at 18 hours.

The above is based upon:

T8 retrofits

LED panels

LED high bays

* The Enhanced Capital Allowance is a cash flow benefit

Lighting Energy Reduction = 64%

Return on Investment / Payback period: Payback period of 2.5 years. By incorporating

intelligent lighting controls with PIR sensors and daylight dimming, this could be reduced to a 3 year

period.

ECA allowance of up to 100% can be availed during the first year, we would recommend that the

accountants be advised prior to carrying out this work.

1.4 Project Financing:

EECO2 can provide third party financing as an option for the energy reduction project including sorting

out forms from Carbon Trust, securing Loans and carrying out the work. We have tried to keep the

project a cash positive assessment, thereby the client can accrue energy saving benefits from day one.

The loan including interest repayments would be spread over 4 years (48 months), with a monthly

repayment amount of £1,695.61 and a monthly energy saving of £1,716.52.

Our fee for conveyance and Project Management should this option be explored would be an upfront fee

of £4,000 towards setting up the third party financing.

1.5 Conclusions:

In order to keep up with upcoming legislation, it is recommended that the existing T8 light fittings be

replaced with LED light fittings, this would result in a substantial reduction in energy consumption with

added benefits in reduced maintenance due to higher lives of these light fittings and reduction in cooling

demand due to lower sensible gains due to lighting.

As the site is currently looking at adding cooling to meet regulatory compliance, incorporating LED lighting

would assist in lowering the cooling capacity needed at site, hence reducing initial CAPEX required for the

cooling plant.

This would result in an energy reduction figure of a 64% reduction in lighting energy due to conversion

from fluorescent lighting to LED lighting.
