Haringey Council cuts energy consumption by 68% with RE:FIT LED programme

06 January 2016

Swapping outdated fluorescent and halogen lights for energy efficient LEDs in 16 key buildings has cut Haringey Council's annual electricity consumption by more than 850,000 kWh

Completed under the Mayor of London's RE:FIT framework, Minimise Energy carried out the programme on behalf of Imtech Low Carbon Solutions, helping the council save £100,000 a year. The programme has cut annual carbon emissions by 452 tonnes - equivalent to the carbon footprint of a million car miles.

The RE:FIT programme provides public bodies with the funding support needed to achieve substantial financial cost savings, improve buildings' energy performance, and reduce carbon emissions. Haringey Council identified 16 buildings which could be grouped together in one RE:FIT programme. This would allow the council to upgrade its lighting infrastructure and improve sustainability, with both the equipment and installation financed under an energy performance contract.

Minimise Energy audited all 16 buildings, identifying savings and completing detailed calculations which formed the basis of the RE:FIT Energy Performance Contract. On appointment, Minimise finalised the new lighting design for each building, reducing the number of fittings needed wherever possible, installing lighting controls to maximise savings, and ensuring optimum lighting levels.

The programme included seven libraries, an education centre, two nursing homes, three care centres, a museum housed within a listed building, and two council offices.

All work had to be planned to minimise disruption and maximise safety. To do this, Minimise put in place a strategic plan which enabled the teams to work flexibly across up to five sites simultaneously, ensuring that work was completed at the optimum time for each location.

Throughout, Minimise worked closely with the council's EPC contractor, Imtech Low Carbon Solutions, and council staff to ensure that a flexible approach was maintained at all times.

Now complete, the new LEDs have reduced lighting energy consumption by an average 68%, with the greatest savings achieved at the River Park offices, where additional lighting controls have resulted in a 77% reduction. Over five years this will save the council more than £500,000 and cut carbon emissions by 2,290 tCO2.

Key benefits
• 68% energy saved (average)
• Maximum energy saving of 77%
• 850,000 kWh saved pa
• £500,000 saved over 5 years
• Average return on investment period: 3.5 years
• Carbon emissions reduced by 2,290 tCO2 over 5 years

Sam Stageman, Sales Director at Minimise Energy, said: "This was a complex project. We needed to complete a thorough audit to identify accurate savings at the outset as this forms the basis of the energy performance contract.

"We also had to demonstrate significant savings, a workable return on investment timeframe and provide a flexible approach to accommodate these high footfall, public locations.

"Careful planning and good communication was key - and the result is less energy used, ongoing savings, and improved lighting - all funded through the RE:FIT programme."
