The Problem

Your plant room and chiller plant run 24/7. So do your energy costs and emissions.

Hotels, hospitals, nursing homes and large institutions depend on constant heating, hot water and cooling. But many still rely on ageing boiler rooms, diesel/LPG systems, fixed-schedule chillers and limited real-time control — creating high operating costs, avoidable emissions and exposure to volatile fuel and energy prices.

The scale of it

Heat is expensive, constant and carbon-heavy.

For buildings that never stop, producing heat and hot water is one of the largest operating costs and one of the biggest sources of emissions.

Indicative annual cost

$200–400K

Hot-water energy cost for a single large institutional building.

Typical thermal-load share

15–40%

Share of institutional building energy linked to hot water, heating and related thermal/process loads, depending on property type and climate.

Cooling share of A/C energy

40–70%

Share of a building's electricity bill that can be driven by air conditioning — chillers alone are typically 60% of that A/C load.

Potential emissions reduction

Up to 80%

CO₂ reduction with renewable, heat-pump-based systems and AI optimisation on cleaner electricity.

Figures are indicative and vary by site size, fuel source, climate, operating profile and electricity mix. Site-specific savings are confirmed through an energy assessment. Sources available on request.

Why it happens

Round-the-clock demand, met by legacy boilers.

Complex buildings can't turn the heat — or the cooling — off. Guests, patients and residents need reliable hot water, warmth and cool air every hour of every day, so the plant room and chiller plant run continuously, often on ageing equipment, fixed schedules and limited visibility or control.

The result is wasted energy, exposure to volatile fuel prices and emissions that are hard to measure, let alone reduce.

The legacy plant room

Boilers burning diesel, mazut or LPG create waste, high costs and CO₂ emissions.

  • Fuel-heavy systems running 24/7 to guarantee supply
  • Reactive maintenance and little real-time visibility
  • High exposure to energy-price volatility
  • Emissions that are difficult to track or verify

Where existing boilers cannot yet be replaced, Dotz Energy can integrate emissions-reduction solutions — including flue-side CO₂ capture where technically and commercially suitable.
