Leeson Lane is a new seven-storey office block connecting to Spruce House, which is a historic Dublin Building where Irish revolutionary Michael Collins was prepared for burial before lying in State in 1922 at Dublin’s City Hall. The state-of-the-art office development includes various mechanical and electrical systems that set a new benchmark for green building practices, including energy efficient heat pumps and a control system that allows natural ventilation throughout the building.

Among the design solutions incorporated into the building were customised breakout meeting areas and collaborative workspaces to accommodate the occupants' different ways of working. As part of our scope, we integrated a building management system (BMS) with the façade controls and a lighting control system throughout the building to meet the 20% renewable ratio requirement to achieve a nearly Zero Energy Building (NZEB).

Darren Kelly, Principal Engineer, commented, “Whilst collaborating with the design team, we ensured Leeson Lane was fully compliant with both Part L and NZEB requirements, amplifying the client's brief of a sustainable development. In addition to improvements mentioned above, daylight harvesting was installed to reduce reliance on artificial lighting and enhance energy efficiency.”
