The Project
Mowlam Healthcare Case Study Overview
Celtic Dynamics was tasked by Mowlam Healthcare’s management to identify energy savings and secure grant funding. Through detailed energy audits, Celtic Dynamics identified annual cost savings of €1,331,534 and €1,313,172 in eligible grant funding to support implementation.
By investing in energy efficiency, Mowlam positions itself as a forward-thinking leader in the Irish healthcare space, aligning with national and EU sustainability goals and enhancing its reputation among regulators, funders, and residents’ families.
Key Achievements
Energy Savings Achieved
The energy savings of 10,252,637 kWh were achieved through conducting energy audits at each site and implementing energy upgrades identified at each site. Through comprehensive audits, the team identified annual cost savings of €1,331,534.
Additional Benefits
The combined annual carbon savings achieved across Mowlam Healthcare’s 32 nursing homes are equivalent to planting 109,343 trees. This represents a substantial environmental impact, highlighting the scale and effectiveness of the energy efficiency measures implemented across the group.
Successful Upgrades
Several energy efficiency measures were successfully implemented, including Solar PV installations, heat pump upgrades, LED lighting retrofits, lowered domestic hot water (DHW) temperatures, wall and roof insulation, and window replacements. These upgrades delivered total savings of 2,277.64 tonnes of CO₂.
Identifying Funds
Celtic Dynamics identified €1,313,172 in eligible grant funding to support implementation across Mowlam Healthcare’s 32 nursing homes.
Key Energy Solutions
Solar PV Installations
The planned installation of solar PV systems across the company’s nursing homes is expected to generate 2,561,288 kWh of clean electricity annually, resulting in projected energy cost savings of €1,001,165 and a reduction of 823.80 tonnes of CO₂ emissions. These systems support carbon neutrality goals while strengthening long-term energy resilience.
Heat Pump Upgrades
The rollout of modern heat pump technology is anticipated to significantly reduce fossil fuel consumption for heating, resulting in annual energy savings of 6,206,359 kWh and a carbon reduction of 1,062.36 tonnes of CO₂. This shows a substantial decrease in emissions, supporting the company’s commitment to sustainable operations and progress towards net-zero targets.
LED Lighting Retrofits
Upgrading lighting to high-efficiency LEDs throughout the nursing homes is expected to deliver annual electricity savings of 308,892 kWh and reduce energy costs by €127,305. This measure will also cut carbon emissions by 98.48 tonnes per year, while enhancing lighting quality and reducing maintenance requirements across all sites.
Lowering DHW Temperatures
Optimising domestic hot water temperatures is projected to save 872,760 kWh of thermal energy and €90,164 annually, with a corresponding reduction of 199.38 tonnes of CO₂. This approach will help lower operational costs and the overall carbon footprint without compromising resident comfort or safety.
Other Solutions
Wall and Roof Insulation
Investments in wall and roof insulation are expected to yield significant thermal energy savings of 3,122,022 kWh per year, resulting in €261,641 in cost reductions and 715.88 tonnes less CO₂ emitted. Improved insulation will enhance building comfort, reduce heating demand, and support further gains from electrification measures.
Window Replacement
Replacing older windows with high-performance glazing is projected to deliver the largest single-site thermal savings, conserving 7,076,643 kWh of heat energy annually. This upgrade is expected to save €488,057 and reduce carbon emissions by 1,622.67 tonnes, while improving airtightness and year-round comfort for residents.
Together, these solutions are expected to drive major reductions in energy use, costs, and carbon emissions, positioning the company’s nursing homes as leaders in sustainability and energy management.
Services Provided
Each project is unique and requires a tailored approach. Here are some of the services we provided on this project.
Detailed Full Site Energy Audit
We first needed to establish the current state of the energy usage to gauge the immediate priorities. The insights gained from the Mowlam Healthcare Energy Audits are invaluable for future projects.
Working Design
As part of the discovery phase, we gathered important data and metrics to help us decide on the best course of action.
Efficiency Solution Design
We designed a system which would enable the most efficient use of energy going forward.
Management of Project Planning
We managed the project planning throughout the whole process utilising our tried and tested workflow.
Procurement Management
We researched the best suppliers for the different elements that we thought would benefit the project.
Complete Engineering Support During all Phases
Our years of experience in Engineering allowed us to support all phases of the project.
Site Installation, Safety Management & Quality Surveillance
The next phase was to oversee the installation of our recommended items, taking care with safety.
Project Commissioning, Verification & Warranty Service
Finally, the project requires us to commission verified & certified companies to carry out our recommendations.
