MEP Consulting for Wellness Facilities – Energy Optimization in Pool Engineering

After a string of successful MEP projects, our office is now placing special focus on energy optimization in wellness and pool engineering. In our experience, energy efficiency is unfortunately often treated as a secondary concern in this field, so existing water-heating systems end up consuming far more energy than necessary.

This waste most often stems from poor communication between design disciplines. Pool technology plans rarely address the precise, optimal energy demand for heating the water, and end up specifying unnecessarily high flow temperatures. MEP designers, in turn, often accept those specifications without question.

We asked the obvious question: is 60–65 °C heating water really necessary to keep pool water at 28 °C? In our view, in a properly sized system, a lower flow temperature of 45 °C is perfectly sufficient — and high-efficiency heat pumps can produce that temperature without any trouble.

System overview: what drives a pool’s heating energy demand

The system that heats the entire pool volume needs to be examined holistically. The main loss and control factors are: the heating water temperature (moving to a lower temperature requires reviewing and properly resizing the entire circulation system), time-based scheduling (if the facility isn’t open 24 hours, heating should be matched to actual operating hours), structural heat loss (about 60% of pool water heat loss escapes through the walls and floor — accessible surfaces are worth retrofitting with insulation), and evaporation loss (evaporation accounts for 40% of losses, which can be effectively reduced with a pool cover when not in use).

Connecting smart systems together

In a hotel or wellness center with a central cooling system, a water-to-water heat pump can put that cooling energy directly to use, economically heating the pool water. Heat recovered from the cooling water of pool dehumidification/air-handling equipment can likewise be routed into the pool’s heating circuit.

Our structured consulting process

We offer our clients a transparent, three-step process to maximize savings: a free initial site visit (a quick review of the facility’s MEP systems, mapping goals and the main points of energy loss), a detailed energy consulting and audit (thorough data collection from consumption records and utility bills, followed by a tailored package of recommendations for optimizing heating, cooling and ventilation systems), and finally construction support (full project management, preparation of construction drawings, and regular on-site engineering supervision for a smooth rollout).
