Energy management as part of the green and digital transition

What was the main goal of the project?

The energy management system was developed and implemented as part of the broader EU project “Revitalization of the Veli Lošinj health resort through digital and green transition,” worth EUR 2,486,801.36, of which 83.79% is financed from the National Recovery and Resilience Plan 2021–2026.

The project covers the reconstruction and equipping of the Park IV building, construction of a photovoltaic power plant, procurement of electric vehicles, obtainment of the EU Ecolabel, ISO 50001 and ISO 14001 certifications, as well as the implementation of energy management, digitalization, and business robotization.

Since the complex consists of seven buildings of different purposes and technical conditions, the approach to energy management is in line with ISO 50001 principles — ensuring measurable results and enabling continuous improvement.

What does this ISO 50001 approach entail?

The project’s measurement strategy was clearly designed with ISO 50001 in mind, as consumption was separated both by buildings and by main energy consumers — such as swimming pools and kitchens — so that each segment could be monitored and analyzed individually.

This approach laid solid foundations for energy management and EnPI indicator setting, while our role was to ensure that the planned measures could be properly implemented in practice.

Technical solution – from measurement devices to data-driven goals

What solutions were implemented on-site?

Numerous smart LoRaWAN IoT solutions were installed to monitor consumption and indoor conditions:

• air quality sensors (CO₂, temperature, relative humidity, etc.) in common areas and rooms,

• local e-panels for displaying energy and water consumption,

• magnetic window contacts linked to IoT controllers, automatically switching off heating/cooling when windows are open,

• flood detection sensors in bathrooms,

• smart monitoring of water and electricity consumption, monitored per building and for significant consumers such as swimming pools and kitchens.

Managing the HVAC system for energy efficiency

What made this part stand out?

This was the most technically demanding aspect. The existing DAIKIN FXLQ-P Series units were not compatible with standard smart controllers, so a customized solution was developed.

New control units were installed and connected to Milesight WS301 window sensors, which detect whether a window is open or closed. This information is transmitted via the Milesight UG67 gateway to the Beaver IoT platform (hosted on the AMR Emasys server), which analyzes the data and sends commands to UC300 controllers.

In this way, the system automatically switches off heating/cooling when windows are open and turns it back on when they are closed — preventing energy waste and ensuring a more comfortable indoor environment.

Empowering the user in energy and water management

What benefits are already visible?

The system has brought several concrete benefits. First and foremost, it enables precise monitoring and optimization of energy and water consumption – the foundation of any serious energy management.

Thanks to water leakage sensors, issues can be detected in time, reducing the risk of damage, while comfort levels for patients and staff are now more stable and improved.

Most importantly, there are now reliable data to support decision-making and continuous system improvements in line with ISO 50001 principles.

In this way, the project laid solid foundations for the further digital and energy transformation of the Veli Lošinj Health Resort, as well as its future ISO 50001 certification.

How was the user enabled to get the most out of the system?

After implementation, staff training was conducted on all aspects of the remote reading, energy management, and air quality monitoring system.

Support continues through assistance in data analysis, understanding consumption patterns, and setting alarms for excessive consumption – so that users can manage consumption based on data rather than assumptions.
