Installation of new LED bollard bases and retro-reflective
bollards
60 new LED (Light Emitting Diode) bollard bases and
retro-reflective bollard shells have been installed. These
provide an annual carbon saving of around 4.02 tonnes of CO2.
They will also save around £575 in energy costs per year and reduce
maintenance costs.
Installation of solar powered LED bollards
Solar powered, LED lit retro-reflective bollards have been
installed in place of old internally lit, mains powered
bollards. 34 of these have been installed so far and they
will provide an annual carbon saving of around 2.5 tonnes of
CO2. They will also save around £360 in energy costs per year
and reduce maintenace costs.
Installation of retro-reflective bollards
Some bollards do not need internal illumination because
they have no sign face, or they are in front of traffic
signals. In these cases a retro-reflective bollard may be
used in place of old internally lit bollards. About 32
of these have been installed so far and they will provide an annual
carbon saving of around 2.3 tonnes of CO2. They will also
save around £340 in energy costs per year and maintenace will be
reduced. More of these are being installed.
New energy saving street lighting
One example is the 400 new energy saving lights are being
installed to replace some of the old low-pressure sodium street
lights. They will cut energy consumption by 50%. These
provide an annual carbon saving of around 26.9 tonnes of CO2.
They will also save around £3,858 in energy costs per year and
reduce maintenance costs due to their long service life.
New energy saving subway lighting
New energy saving LED (Light Emitting Diode) tubes are
being installed to replace some fluorescent tubes in
pedestrian subways or underpasses. These could save up to 64%
of the energy used. These will provide an annual carbon
saving of around 35 tonnes of CO2 if all 54 subways were
changed. They will also save around £11,000 in energy costs
per year and reduce maintenance costs.
