Case studies

Measured before, measured after.

44%less electricity used out of hours, once schedules were set

Education campus, seven school sites

Controls were fitted to separate essential from non-essential loads and schedule them across a shared campus network. Out-of-hours consumption fell from 18 to 10 kWh an hour.

Also verified: weekend use down 36%, from 408 to 262 kWh a day, for a combined saving of 42%. An investment of €41,370 saves €25,347 a year across the seven sites, a payback of 1.5 years.

74%less electricity used outside working hours, once scheduling was set

Hospital facility

Controls put out-of-hours consumption on a fixed schedule. Weekend use alone fell by 66%, from 166 to 56 kWh a day.

Also verified: an estimated saving of €5,210 a year at the tariff in place at the time. Checked again five years later, the saving had held.

3.4 yrspayback on a car park lighting controls project

Residential development, underground car park

Lighting controls were fitted so the car park lights come on when residents are present, instead of running on a fixed timer. Weekly consumption fell from 3,875 to 2,896 kWh.

Also verified: 979 kWh saved a week, or 50,908 kWh a year, worth about €15,272 at the tariff at the time. Tracked through our own software.

63%of the site's electricity now comes from its own solar

Golf club, coastal site

The clubhouse and machinery shed were fully electrified and a roof-mounted solar array installed, sized from a measured baseline of the site's load.

Also verified: the design took account of the protected coastal setting, including environmental safeguards and access for long-term maintenance.

98.5%of the electricity generated is used on site

Dairy processing site

A 250 kWp rooftop solar array was installed, sized from consumption data measured before the investment was approved.

Also verified: estimated generation of 233,308 kWh a year, avoiding 109.6 tonnes of CO₂, roughly equivalent to 5,480 trees.
