The Project

Over the last five years, the energy management team has led an extensive renewal of its energy management programme, shifting focus to energy efficient design and incorporating efficiency for the lifecycle of all Astellas projects.

The energy management team is responsible for upwards of 20 projects per annum for which the core goals are improving efficiency, optimisation of significant energy users, integration of renewable energy and minimisation of waste reduction carbon footprint.

These initial projects included two 1650kW chilled water systems (CHW) plant upgrades, which halved the energy use of the previous system. It also featured canteen building upgrades and a compressed air heat recovery system.

The next phase evolved into design using Leadership in Energy and Environmental Design (LEED) and Excellence in Energy Efficiency Design (EXEED) principles. LEED and EXEED design were applied to a 7,562m2 warehouse expansion project making energy aspects a cornerstone of the design process. This included high performance building fabric, innovation in lighting and ventilation control.

“It’s fantastic to win. It’s a great recognition of all the hard work that’s been undertaken on site and the proactive approach that Astellas Kerry plant has taken to incorporating sustainability into its core values.” Megan Staunton, Site Energy Lead, Astellas Ireland Kerry Plant 

What’s next?

Astellas Ireland’s energy management team wants to continuously improve efficiency across all systems with target upgrades of equipment and the incorporation of new technologies and control strategies, including air-to-air plate heat exchangers in air handling units (AHUs), floating temperatures on low temperature hot water (LTHW) systems, digital addressable lighting interfaces and production line efficiency projects.

The team is also aware of the importance of staff engagement and awareness, with each area having an energy champion who conducts audits and suggests improvements.
