Coventry Student Accommodation, Coventry
- Lamp efficacy
Ensuring the lamp efficiently converts electricity into light (lm/W).
- Ballast classification
Controlling the electricity supply to the lamp (Energy Efficiency Index).
- Luminaire distribution
Controlling light emission using optics which bend and shape the light to the correct location.
- System efficacy
Improved luminaire efficacy resulting in significant energy reduction.
- Presence/absence detection
Lights automatically turn on when a person enters a space and automatically turn off when it is unoccupied.
- Daylight detection
In the stairwells the use of daylight photocells have been used to reduce energy when natural daylight is available.
- Constant illuminance
A function designed to produce correct light levels for the duration of the maintenance period.
- Task-scene setting
Allowing the user to set scenes and adapt the lighting to different tasks.
- Timed off
Automatic cut-off can be installed to turn all lights off during unoccupied hours.
- Task lighting
Each area has been specifically designed to suit the particular task to ensure that energy usage is kept to a minimum.
- Zoning of lighting
Zoning of lighting
Lighting is zoned according to area use.
- Maintenance schedule
Improved luminaire lifetime of 50,000 hours resulting in reduced maintenance costs.
- Waste light
Eliminating waste light which does not hit the intended target.
Taking advantage of light which is reflected from the surface within the space.
- Visible smart metering
Visible smart metering
As part of the trial the energy usage will be measured to determine the exact energy reduction across all areas.
Migration to LED lighting reduces energy consumption up to 75-80% and lowers maintenance costs
UNITE is the UK’s leading provider of student accommodation, providing homes to 42,000 students in 130 properties across 23 of the UK’s strongest university cities. As part of a trial UNITE has installed LED lighting across an entire property.
In partnership with MITIE Lighting the complete Coventry site has been refurbished with the latest Thorn LED lighting technology.
The refurbishment covered lighting in the bedrooms, ensuites, kitchens, office, reception area, laundry 1room, corridors, landlord common area and external areas. The luminaires, including Thorn’s Club, Leopard, IndiQuattro, Lightstream, Chalice, Novaline and Olsys complemented the requirements of each space and the differing user requirements. In some areas the use of integral sensors ensure the lighting is only on when required.
By switching to LED, UNITE will gain energy savings of up to 75-80%. This will significantly reduce the lighting energy costs associated with running the accommodation.
The typical 50,000-hour LED lifetime will also substantially reduce maintenance requirements and costs.
In some of the larger areas, a payback period of around 3 years is expected. This may be higher in some of the other areas depending on the quantity of luminaires and the operating hours expected over a typical annual period.
Finally, the quality of light has also been improved in all areas. All the living spaces now benefit from a crisp, clean feel.
- Energy saving: Up to 75-80%
- Payback: 3 years
- LED lifetime: Up to 50,000hrs
