Achieving Optimal Energy Efficiency and Noise Reduction: The Google Bolands Mills Project

In the heart of Dublin’s vibrant business district, the Google Bolands Mills project stands as a testament to innovation and sustainability. Spearheaded by a team of renowned professionals including Ethos Engineering, Arup, Jones Engineering Group, and Henry J Lyons, the project aimed to achieve exceptional energy efficiency while maintaining stringent noise level requirements.

The primary focus of the project was to achieve the lowest specific fan power possible, a feat that required meticulous planning and collaboration among all stakeholders. Versatile played a crucial role in the project by supplying fan coils and valve sets, with a particular emphasis on precision hydraulics control using Pressure Independent Control Valve (PICV) sets.

One of the most significant challenges faced by the team was managing noise levels in a scenario without typical sound-dampening elements such as suspended ceilings. Despite this obstacle, the project demanded noise levels to be reduced to below 35 dB, highlighting the need for innovative solutions.

To address these challenges, the team worked tirelessly to develop a tailored solution that would meet both energy efficiency and noise reduction requirements. PICV valve sets were strategically employed to provide precise hydraulics control, optimizing the performance of fan coils and ensuring efficient operation.









In addition, a groundbreaking innovation came in the form of a tailored NZeb Fan Coil, specifically designed to operate efficiently below 35 dB. This innovative solution empowered the use of fan coils at lower speeds, significantly enhancing the Coefficient of Performance (COP) for both heating and cooling.

Through collaborative efforts and innovative thinking, the Google Bolands Mills project successfully achieved its objectives of exceptional energy efficiency and noise reduction. By embracing cutting-edge technologies and bespoke solutions, the project sets a new standard for sustainability and performance in the built environment.
