Smart energy and building monitoring for nursing homes
Cut the heating waste that open windows and round-the-clock operation create, keep residents comfortable and safe, and turn HIQA compliance into continuous evidence, with one monitoring and control stack.
Three forces converge on the nursing-home sector
Volatile energy prices
A nursing home's load runs continuously and much of it cannot simply be switched off. Better operational evidence helps distinguish essential demand from controllable waste and supports properly timed investment decisions.
Margin squeeze
The BDO/NHI sector survey found roughly half of Irish nursing homes made no profit, with operating costs up far faster than Fair Deal rates and 77 homes closed since 2018. With staff costs largely fixed, controllable overheads like energy are where margin is defended.
HIQA tightening
Strengthened powers under the Health (Miscellaneous Provisions) (No. 2) Act 2024 and the Care and Welfare regulations (SI No. 1 of 2025) raise the bar on premises and infection control. A pending Design Guide for Long-Term Residential Care will let HIQA assess infrastructure directly. Monitored data turns Reg 17 and Reg 27 into evidence.
Three pillars: cost, comfort, compliance
Cost & margin
"Half of Irish nursing homes made no profit last year. Energy is one of the few costs you control."
Heating dominates the nursing-home energy stack at roughly 50–55% of total spend, most of it on fossil fuels at current-year prices. Older converted stock runs on rudimentary controls (fixed-time clocks, no zoning, radiators heating rooms with the windows wide open), while the genuinely irreducible loads (hot water, laundry, catering, lifts) run around the clock. The largest controllable loss in any home is the heating that escapes through open windows and over-shoot, and it is addressable without touching clinical care.
The levers are well understood: setpoint discipline saves 8–12% of heating energy, open-window shutoff a further 4–8%, and sub-metering visibility alone is worth around 10% before any control change. Against a sector benchmark of roughly €2,161 per occupied bed per year, a 15–22% cut on the heating portion is real money recovered from a budget line that would otherwise only rise.
Resident comfort, dignity & air quality
"Frail residents feel every degree, and every draught."
Older residents are far more sensitive to temperature swings and poor air than the general population, and a nursing home is their home around the clock. Continuous monitoring keeps rooms in a stable comfort band rather than cycling between over-heated and cold, and demand-controlled ventilation manages CO₂ and humidity in the lounges and dining rooms where residents spend their days. Crucially, it does this with privacy intact: occupancy sensing is radar or motion only, never cameras or audio, so it is appropriate for bedrooms and dementia units where dignity is non-negotiable.
The same air-quality layer that keeps residents comfortable also produces the infection-control data that matters to families and inspectors alike, a measured environment, not an assumed one.
Compliance & building risk
"HIQA increasingly wants evidence, not assurances."
HIQA's strengthened regime makes the condition of the building a regulatory question, not just an operational one. Regulation 17 requires adequate heating and a comfortable environment; inspectors have cited cold bedrooms and communal areas as non-compliance. Regulation 27 drives ventilation and infection-control expectations. Continuous, time-stamped temperature and CO₂ data turns both into an evidence trail a home can show, instead of a position it has to defend after the fact.
Building risk runs alongside compliance. A home is never empty, but it is least-staffed at night, exactly when a burst pipe, a stuck boiler or a failed hot-water loop becomes a resident-safety event rather than a maintenance ticket. Leak sensors catch water damage within minutes, automated hot-water temperature logging covers Legionella control without manual rounds, and anomaly detection flags equipment drift before a mid-winter heating failure forces an emergency.
A modular monitoring and control stack
Each capability can stand on its own or form part of a phased scope. One possible starting point is heating control and open-window response, followed by air quality, sub-metering and water monitoring where the site evidence supports them.
Heating control & open-window shutoff
Smart radiator thermostats on every radiator, paired with window-contact sensors that pause the valve the moment a window is opened and resume when it closes. This is the single biggest controllable loss in a nursing home: staff open windows to clean and air rooms each morning, then radiators run against open windows all day. Setpoint discipline alone saves 8–12% of heating; open-window shutoff adds a further 4–8% in buildings where it's a habit. Contact sensors on external doors flag the propped-open or broken automatic entrance that quietly bleeds heat.
Lighting & privacy-safe occupancy automation
Radar occupancy sensing plus daylight-harvesting controls drive lighting and setback without cameras or audio, no personal data, suitable for bedrooms and dementia units. Radar is the nursing-home difference: it reliably senses slow-moving and seated residents that conventional PIR sensors miss, so automation can finally extend to corridors and resident areas that motion sensors could never safely cover.
Air quality & demand-controlled ventilation
Continuous CO₂, temperature and humidity monitoring in lounges, dining rooms and high-occupancy areas drives Optim Vent and any existing MVHR system. Demand-controlled ventilation lowers infection-relevant CO₂ and lowers bills at the same time, and the logged data underpins the HIQA Regulation 27 (infection control) ventilation narrative, evidence you can show an inspector instead of an assurance you have to give.
Kitchen & laundry sub-metering
A multi-channel current-monitoring hub with CT clamps breaks the bill down across the heaviest 24/7 loads, catering and laundry circuits, plus hot water, HVAC, lifts and the three-phase mains on the same hub. Commercial kitchens and on-site laundries run almost continuously and are where unmonitored waste hides: equipment left on overnight, immersions stuck on, drifting plant. Sub-metering visibility alone is worth around 10% before any control change, by simply showing where the waste is.
Water-leak detection & hot-water safety
Wireless spot, zone and membrane leak sensors on plant rooms, kitchens and bathrooms catch bursts and the running taps and faulty cisterns that a quarterly water bill only reveals in arrears. The same temperature-monitoring layer logs thermostatic mixing valves and stored hot water automatically, replacing the manual Legionella temperature checks that consume caretaker time, and giving a continuous safety record rather than a clipboard.
One dashboard: Optim EOS
Everything above feeds the Optim EOS dashboard, hosted in Ireland, with role-scoped views: the Person in Charge sees comfort and air-quality status, the Facility Manager sees alerts and live operations across sites, and the CFO or Board sees the financial and compliance picture. The same data forms the HIQA-ready evidence trail and the baseline that proves each home's savings before the next phase.
When monitoring proves the case for capital
Heat-pump readiness
Many homes still run on kerosene and natural gas. A sub-metered heating baseline can strengthen the case for moving to air-source heat pumps and size the project on real consumption rather than guesswork. The Support Scheme for Renewable Heat (SSRH) may be relevant where the operator and project meet the current rules.
Solar PV monitoring & expansion
For homes with existing solar, the dashboard can turn a static inverter readout into a live operational view of generation, self-consumption and export, and show how PV interacts with heating, hot water and laundry. Potential SEAI solar support depends on the current scheme rules and project.
Sector benchmarks and an illustrative example
Published sector benchmarks help frame the opportunity. Each home's own bills, operating data, equipment and care requirements determine the proposed scope, savings range and payback.
Sector energy intensity
The BDO/NHI Nursing Homes Survey provides a benchmark of roughly €2,161 per occupied bed per year. Heating (space and hot water) is typically 50–55% of a home's energy spend, making it the largest single addressable cost.
Heating savings range
Carbon Trust and SEAI sector data put combined setpoint discipline and open-window shutoff at 15–22% of heating energy in 24/7 residential buildings, with the upper bound limited by round-the-clock elderly-resident use and the HIQA Reg 17 temperature floor.
Visibility effect
Sub-metering visibility alone is associated with around a 10% reduction before any control change is made, the building simply shows where waste sits and operators act on it.
Illustrative home (~50 beds)
Applying the published sector benchmarks, a scope covering heating control, open-window response, common-area air quality and electrical baseline visibility could address roughly €11,000/year of avoidable cost. The home's own bills, operating data, installed price, ongoing service cost and confirmed support determine the actual business case.
Our four-step process
Independent evidence where needed
Where an independent professional energy audit is needed, we help coordinate the process and ensure its findings can inform practical system design and investment decisions. Potential SEAI support is checked against the current rules.
Tailored design and quote
A hardware and software specification matched to the building, its current systems and the priorities the audit surfaces, not a one-size-fits-all kit. Sized as a single home or as the first site in an estate rollout.
Installation around care
Wireless, battery-powered devices retrofit without ductwork or structural work. The team works room-by-room around care routines and meal times, no resident is decanted and daily life continues uninterrupted.
Continuous monitoring & support
Quarterly reviews, optimisation and ongoing upgrades, with the platform, alerts and firmware managed remotely. The data forms the HIQA-ready evidence trail and the measured baseline for the next home in the group.
Where the money may come from
Eligibility for each scheme depends on the operator's profile, the project scope and SEAI's current programme rules. We help assess fit and apply where appropriate, we don't promise grants we can't deliver.
If controls, sub-metering or a building management system form part of the scope, read our practical guide to BMS grants in Ireland before ordering equipment or starting work.
