The metering behind Ireland's most successful public-sector energy campaign

The Office of Public Works manages most of the Irish State's property — hundreds of government offices and police buildings. Their energy-conservation programme needed measurement it could trust and staff could rally behind. We built the metering system that delivered both.

At a glance

The Office of Public Works (OPW), a major Irish Government agency, manages most of the State's property portfolio — hundreds of owned and rented government offices and police properties. Its energy-conservation campaign, Optimising Power @ Work (OP@W), was launched to the wider public sector in 2014 to drive behavioural change. To maximise its effectiveness, OPW needed a custom energy-management and measurement-and-verification solution that fit their procurement tender. Full Stack Energy delivered a bespoke revenue-grade metering system and gateway, plus a browser-based app, giving public-sector teams the data to champion and verify their energy reductions.

01The brief

A conservation campaign that needed proof

Optimising Power @ Work is an energy-conservation campaign built on behavioural change — encouraging public-sector staff to use energy more carefully. A campaign like that lives or dies on evidence: people change behaviour when they can see the difference they’re making, and managers can only champion progress they can actually measure.

OPW manages a vast, varied estate — hundreds of government offices and police properties — so the measurement had to be consistent across very different buildings. And as a public body, it had to fit a formal procurement tender, with all the rigour that implies.

OPW needed a custom solution for their bespoke energy-data-management needs: metering that would let public-sector teams champion their achievements and promote their progress through internal awareness tools — not just a dashboard, but the engine of a national behavioural campaign.

The Advisor Optimising Power @ Work dashboard: summary tiles for cost, carbon and energy use, a site league table ranking facilities by cost and carbon, and quick links to data, tariff and reporting tools.
The Advisor platform behind OP@W — cost, carbon and consumption surfaced per facility, with a site league table teams used to track and champion progress.
02What we did

Frame it, build it, make progress visible

We started by framing the domain problem and objectives with OPW’s stakeholders, then built hardware for fast facility assessment and a browser app that turned readings into something staff could act on.

The bespoke metering gateway: a central unit with a wired antenna and eight pairs of powered current-transformer clamps branching off it for multi-circuit measurement.
The gateway design — one unit reading multiple powered CTs per facility, built for fast install across a very varied estate.

A conservation campaign is really a measurement campaign. People change what they can see — so the meter isn't the back office, it's the front line.

03The outcome

25% savings, and a campaign that scaled

The Optimising Power @ Work scheme delivered average annual savings of 25% across 300 participating central-government facilities over five years — making it the largest and most successful campaign of its kind in Ireland. The metering gave teams the data-driven metrics they used to engage office staff in managerial and behavioural change.

On the back of that success, OPW expanded the programme to the largest office in each local authority, supporting the drive towards NEEAP 2020 targets. As an Irish company — with parent ResourceKraft well known to Local Authority Energy Managers — Full Stack Energy then scaled the system up for local-authority bodies beyond their main offices, providing the equipment and support to measure and manage major energy consumers such as leisure centres, large buildings and plant across each city or county.

04From the team

What we’d tell you over coffee

The thing people miss about OP@W is that the engineering served a behavioural goal, not the other way round. The cleverest meter in the world is useless if a facilities manager can’t turn its readings into a story that makes staff switch things off. We built for that — fast assessment, a clear app, progress you can point at.

Being an Irish company mattered here in a way it doesn’t always. ResourceKraft was already known to Local Authority Energy Managers, so scaling the programme out wasn’t a cold sell — it was extending something the sector already trusted to leisure centres, depots and the bigger consumers beyond head office.

Common questions about this M&V metering programme

OP@W is the Office of Public Works' energy-conservation campaign built on behavioural change across the Irish State's property estate. Powered by this bespoke metering, it delivered average annual savings of 25% across 300 participating central-government facilities over five years — the largest and most successful campaign of its kind in Ireland.

Because a conservation campaign is really a measurement campaign — people change what they can see, and managers can only champion progress they can measure. A bespoke revenue-grade meter and gateway feed a browser app that turns readings into the data-driven metrics teams use to engage staff and verify their reductions.

Yes. After OP@W's success, OPW extended it to the largest office in each local authority, and Full Stack Energy scaled it further for local-authority bodies — measuring and managing major consumers such as leisure centres, large buildings and plant across each city or county.
