INTRODUCTION
YOUR PROACTIVE APPROACH TO REDUCE YOUR ENERGY CONSUMPTION AND ANTICIPATE EUROPEAN REGULATIONS
- HVAC* installations represent approximately 35% of buildings energy consumption**, a real challenge considering the critical energy cost increase we are facing in Europe.
- Climate change and environmental degradation are an existential threat to Europe and the world.
- To overcome this challenge, the European Commission, with the Green Deal and REPowerEU initiatives, proposes ambitious targets in terms of energy efficiency and greenhouse emissions.
- An energy audit is an assessment of the current performance and operation of a chiller plant, highlighting areas of concern and potential improvements, to propose to our customers with suitable measures for energy conservation, sustainability and decarbonization.
- Our BluEdge® service team can conduct an onsite health check and present you an audit report.

CASE STUDY
- HOSPITALITY
- Our customer is one of the largest and famous hospitality companies in the world. Delivering exceptional guest experience is part of their main value.
- One of its hotels located in the city center of Rotterdam (the Netherlands), asked our team for an Energy Audit of its old chillers (other brand chillers).
- The objective was double: first, to meet the requirements of the company in satisfying guest’s comfort with lower noise. Secondly, to be compliant with the new regulations in terms of energy efficiency and gas emissions.
- After conducting an energy audit, our BluEdge service team based in the Netherlands, recommended replacing the existing chillers system with a complete and optimal solution, including 2 x optimized air-cooled scroll chillers with new control for plant room supervision and new variable speed pumps.
- Targets have been met, and our customer could benefit from:
- 72% of energy savings.
- A ROI (return on Investment) < 3 years.
- Low sound for its guest’s comfort and localization in the city center.
