2014 Performance Highlights
During 2014 significant progress was made in reducing the energy demand and developing new renewable energy infrastructure at both
the Pembridge and Selby sites. Energy awareness and involvement has been raised across the business with circulated emails and a
poster campaign.
At Selby a bespoke 15,000 m 2 Rooftop Solar PV system was installed. This 2.5 MWp system is expected to generate 2.14 GW . h of
electricity per year; enough to power 500 homes. Inside the building, intelligent controls were installed alongside LED luminaires. As a
result the energy consumption has been drastically reduced and the building now achieves an EPC grade of ‘A’. The overall operational
cost of the building’s lighting has fallen by 91%, with savings generated expected to pay for the installation of the system in just over
three years. A heat recovery system was also fitted.
In Pembridge the new local anaerobic digester (AD) plants came on stream at the end of the year, to export both heat and power. The
500 KVA electrical input, which will provide 2 GW . h annually, has been synchronised with the PV scheme to create a priority system
where grid electricity has the lowest demand priority. Based on 2013 consumption the AD plant will replace 2.7 GW . h/a of electricity i.e.
40% of the current grid demand. This site will also provide 2 GW . h per annum of heat energy in the form of hot water which is directed to
two recently installed heat recovery systems. Inputs from the AD plants are not included in the graphs below as full production of energy
did not start until January 2015.
During 2014 the Pembridge site was accredited with the ISO 50001 Energy Management System. A similar initiative is planned for Selby.

Action Plan
l Install gas and electricity sub–metering in all warehouse areas,
individual production lines and ancillary machinery, to enable
targeting of areas for energy savings. Install centralised energy
monitoring software that feeds from the sub-metering data.
l Utilise centralised energy consumption monitoring data to
enable management to understand consumption demands,
trends and opportunities for future energy savings.
l Install LED lighting, where practicable, throughout the
business.
l Install daylight detection sensors to factory lighting to ensure
that electric lights are only used when daylight levels are
below a practical minimum.
l Install proximity detection shut–off to lighting, where
practicable and not already in place, throughout the business.
l Install on-site low or zero carbon energy sources for both
Pembridge and Selby production plants, in order to meet the
Kingspan Group Zero Net Energy Target.
l Ensure teleconference facilities are used by staff.
l Reproduce the success of the manufacturing energy
awareness scheme through an office education programme for
all staff to increase energy efficiency and reduce consumption.
A new OPTIM-R line was commissioned which increased
electrical energy demand for the site which meant the
grid electricity did not decrease by a significant amount
however grid natural gas reduced as renewable heat from
AD plant iis being used instead of CHP plant which uses
natural gas. The CHP is being de-commissioned.
The increase in consumption
from on site production is due
to the introduction of the PV
array at Selby.

Emissions from direct and indirect energy consumption were calculated using conversion factors
obtained from the Department of Environment, Food and Rural Affairs (Defra), by way of the UK
Greenhouse Gas Inventory for 2009.
This proposed an emissions level of 0.20374kg CO 2 per kWh of natural gas consumed, and a
conversion factor of 0.54055g CO 2 per kWh of grid electricity consumed (5–year rolling average).
