The redevelopment of Ireland’s Electrical Supply Board’s Dublin office building has seen it become one of the most sustainable workplaces in Ireland. Opened in July 2022, it offers a new approach to office design, serving as an exemplar of how offices can be refurbished and built to operate on the fraction of the energy that is typically used.

Almost every energy system was reimagined, including a series of heat pumps, phase change stores and a ground loops that work together to move energy seamlessly around the building. We combined this advanced technology with simple, low cost solutions, such as the use of single coil, four pipe fan coil units that offer dramatically lower energy consumption at a reduced install cost.
We installed a new form of hybrid ventilation to take advantage of Ireland’s naturally cool climate, combining the best of active cooling, mechanical ventilation and natural ventilation. The result is an office space that exceeds traditional ventilation standards and produces better air quality and lower energy usage than any of these solutions individually.

We undertook a detailed study of the building, considering the orientation of each façade and the shading provided by adjacent structures and other parts of the building. Using this data, we altered the glazing dimensions and solar performance to suit each area. This helped reduce both overheating and heating load.
Additionally, our initial monitoring has shown that there is almost zero heating required and that heat used is almost entirely recovered from cooling loads such as computer rooms.

Designed as a zero local pollution building, it has no fossil fuel connections. This means that, with the national grid, the operational carbon impact of the building will approach zero over time.
The redevelopment of the headquarters in Dublin also presented BDP’s M&E engineers with an opportunity to research and contribute towards the advancement of a sustainable measures for future workplaces across Ireland.
