Project Fitzwilliam – ESB Head Office Redevelopment

Linesight provided Cost Management services for the development of ESB’s new corporate HQ – an example of next-generation sustainable design in large office buildings. 

Located in the middle of Dublin’s historic Georgian core, known as The Georgian Mile, the building was designed to be one of the most efficient and sustainable commercial office developments in Dublin City, while sensitively respecting and enhancing the Georgian streetscape. 

The main development consists of two interconnected office buildings – one accommodating the ESB Head Office, whilst the other was leased and sold by ESB to support the commercial business case for the development. This 45,000sq.m. development incorporates a considerable number of innovative sustainable technologies which will reduce carbon emissions and running costs, delivering a BER A3, near zero energy building. Innovations include: 

• Heating and cooling are provided by ground and air source heat pumps resulting in zero local emissions 
• Fresh air system providing up to 30% further fan energy systems over traditional constant pressure systems 
• The building uses night cooling strategies to pre-cool the building in warmer weather.  
• A ratio of solid to glazed areas to achieve an appropriate balance between natural light, heat gain and glazing heat loss 
• Inclusion of 4.8km of ground source heating and cooling loops, 28kWp roof-mounted solar panels, and efficient energy management  
• Balance of glazing and solid material to maximise solar gain and day light  
• Implementation of green roofs to promote ecological diversity 
• Rainwater harvesting and natural well water to achieve minimum 70% reduction in water usage
