Case Study

Conclusions

The Need for EFFECTIVE Lighting Controls

75% of controllable lighting sold in

Europe is not controlled when installed(source: Frost & Sullivan)

41% of electricity demand across all

sectors is due to lighting(source: CIBSE)

The Need for EFFECTIVE Lighting Controls

80%

75% of controllable lighting sold in

80% of buildings that will exist in the UK

in 2050 have already been built (source: Greater London Authority)

The Rise of Mixed-Use DevelopmentsExample: 100 City Road, London

Residential rents are outstripping office rents, yet there is a shortage of office space

Office, residential, hospitality and retail spaces are co-locating

Lease lengths are decreasing. 25% decrease in London over past 10 years

New development schemes have elements of multiple use, under single landlord

This is driving need for greater flexibility in building and energy management

Mega Trends

Prefabrication and Modular Construction

Prefabrication and modular construction is growing globally, and can bring numerous benefits:

• 3-4 week reduction in project schedules

• 5% reduction in construction site waste

• 5% reduction in material use

• 6% reduction in project spend

Lighting controls integration into prefabrications is attractive, and could increase adoption – but also requires easy commissioning!!

Mega Trends

User Perception with ‘Traditional’ Lighting Controls

• Require specialist engineers to re-program, often at high cost (£1000 a day not unusual)

• Time-consuming to re-configure

• Often require intervention into infrastructure to resolve issues

User Software often not intuitive;‘written by controls engineers

for controls engineers’

Mega TrendsLED luminaires sell into retrofit

We estimate that 80% of LED luminaires sold today are to retrofit existing ‘traditional’ luminaires

Lighting controls have a very low penetration rate into these buildings

Since LED is inherently controllable this creates a significant opportunity

Retrofit

What does the future of lighting control look like

The ideal solution will……..

• Be wirelessly retrofittable into existing building infrastructure

• Simplify existing commissioning processes

• Have a user friendly, intuitive interface

• Report and analyse data from the installation

• Be easy to re-commission after data is analysed

EyeNut Architecture

User Friendly Controls

Lighting control has progressively been taken away from users, via complex software and programming methods

EyeNut hands control back to the users and provide a flexible, supported toolkit for continuous, dynamic use

Intuitive Interface

Configurable Dashboard

Provides useful information about installation to Users and Facilities Managers, including:

• Details of installed devices• Energy reporting• Money saved since installation

Intuitive Interface

Device List via RFID

Devices can be added to network via RFID scanning BEFORE power is supplied, making offsite pre-configuration a reality

This allows lighting control commissioning to begin during prefabrication and modular assembly stage

Intuitive Interface

Energy Management

All EyeNut-enabled luminaires are fitted with electronics & software providing real-time energy measurement capability

System watts consumption is measured at 30 minute intervals during operation

Data can be reported back to user interface and analysed using a suite of reports

Intuitive Interface

Easy Time Scheduling

24 hour profiles can be easily programmed and assigned to luminaire groups using a calendar feature

Intuitive Interface

Mapping

Create building maps from CAD or BIM software and navigate using Google maps functionality

Assign luminaires and controls to their mapped locations

Use maps to create control groups, identify devices, or view energy ‘hot spots’ graphically by area

Controls Strategy

Ambient, accent, perimeter and aisle lighting controlled

independently in each zone

Occupancy sensor in each zone, measuring occupancy by

zone by time of day

Selectively time-schedule layers of lighting in response to

occupancy

Apply minimum necessary lighting during out of hours (staff

training, stocking, cleaning)

EyeNut for Retrofit

Project Example: Retail Department Store

Additional 40% saved by controls additional to saving from LED replacement

1498 kWh/day reduced to 330 kWh/day = 78% Saving

Effective power density of 5.6W per m2

Payback from additional controls investment = 2 years
