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.
Controls put out-of-hours consumption on a fixed schedule. Weekend use alone fell by 66%, from 166 to 56 kWh a day.
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.
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.
A 250 kWp rooftop solar array was installed, sized from consumption data measured before the investment was approved.
We can talk you through a comparable project and how it was measured.

Heating and cooling, solar and EV charging
Removing gas for heating was a big decision for the club, and DCS Group made it easy. From the first site visit they were professional and knew their stuff. They explained the options clearly, sized everything properly and handled the grant paperwork. They worked around a busy golf club with minimal disruption to members and staff, kept the site tidy and safe, and always kept us informed. We dealt with one team from design to handover for the heating and cooling, 180 kWp of solar across four buildings and EV charging in the car park. Because everything is metered, we can see the results: solar supplied, on average, 41% of the club’s electricity this spring and summer. I’d recommend DCS to any club or business thinking about the same journey.
Heat pumps, solar and monitoring
Beyond the results, Donal and his team were exceptional to work with throughout the entire project. They guided and supported us at every stage, making what could have been a complex undertaking a seamless process. Their professionalism, responsiveness and genuine commitment to helping us achieve the best outcome were evident throughout, and the level of care and support they have continued to provide since the project’s completion has been outstanding.
We are delighted with both the results achieved and the relationship we have built with DCS Group, and would have no hesitation in recommending Donal and his team to other organisations considering similar energy and sustainability projects.
The project
DCS Group took Premier Credit Union’s two branches, in Thurles and Roscrea, off fossil-fuel heating. We replaced the storage heaters and the oil boiler with heat pumps that heat and cool the buildings, installed 59 kWp of solar across the two roofs, and added live energy monitoring. Comparing January to September 2026 with the same months of 2025, neither branch uses heating oil any more, CO₂ is down 31% and Thurles is buying 25.6% less electricity from the grid. Solar now supplies about a fifth of each branch’s electricity. Every figure comes from the branches’ own meters.
Solar, heat pumps and hot water
DCS Group have been a great partner for Dooks. They began by measuring how we use energy, then delivered solar, a new heat pump system for heating and cooling, and heat pump hot water. Their team was professional and competent from start to finish. They explained the options clearly, managed the grant process, worked around a busy club and kept us informed at every stage. The results speak for themselves: since the upgrade, our gas costs are down by a third to 40% on the same months of previous years, and solar now supplies over 43% of our electricity. We’d recommend DCS to any club looking to cut its energy costs and carbon.
Solar and monitoring
DCS Group measured our energy use first, so every decision we made was based on real data. They then designed and installed a 690 kWp solar system working around our production with very little disruption. We dealt with one team from start to finish, and they handled the grant application, which covered 22% of the cost. Because everything is metered, we can see the results for ourselves: our energy use is down 28%. I’d recommend DCS to any manufacturer looking to take control of their energy costs.
Energy and water monitoring
DCS Group are our energy partner. They installed energy and water monitoring across our dairy processing site in Tralee, which gives us live data on where our energy goes, right down to individual equipment. That data supports our ISO 14001 certification and helps us keep our Origin Green certification. It has also made a real difference to our running costs: in the first five months, our weekly electricity use fell from around 26,000 kWh to 21,500 kWh. They are easy to deal with, they know their stuff and they do what they say they will. I’d recommend them to any food business that wants to get on top of its energy.
