We completed both a life-cycle environmental and life-cycle cost assessment of the Pembroke Square, Dundrum on a consulting basis. Developed by Hammerson the project centres around the opening of Fallon & Byrne’s flagship food hall, deli and restaurant but also includes plans to create a gastronomic hub and markets. The speciality food hall is supplemented by a 6,000 sqft public space designed for open-air markets, a space for a separate restaurant and a basement leisure facility.
The project is designed to be Ireland’s first building energy rating A, nearly zero energy building and targeting a BREEAM Excellent rating and highlights Hammersons Net Positive Objectives.
Contributing to the BREEAM rating were the LCA and LCC studies completed at both stage 2 and stage 4. Some of the key features contributing towards a significant improvement in life cycle environmental performance were the following:
|Strategy||Percentage improvement in GWP against the baseline|
|Reclaimed Slate Roof Tiles||-3.04%|
|Granular Fill to Basement||-0.96%|
|Solar PV (8kW Grid Connected)||-0.30%|
|30% GGBS cement replacement||-0.11%|
|Replacement: Plasterboard finish for timber||-0.02%|
|Low Impact Carpets||-0.01%|
Full LCA (Stage A1-C4) of the building including substructure, superstructure, internal finishes, external works, people and equipment, operational energy and water.
