Project Details
- Client: Hammerson
- Type: Commercial
- Location: Dundrum, Ireland
- Date: December 2019
- Estimated Lifespan: 60 years
- LCA authored by Gabby Shaw and Pat Hermon from Cerclos
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.
Project Features
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 |
| Basement Removal | -6.19% |
| 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% |
| Reclaimed Bricks | -0.04% |
| Replacement: Plasterboard finish for timber | -0.02% |
| Low Impact Carpets | -0.01% |
Results Summary
Full LCA (Stage A1-C4) of the building including substructure, superstructure, internal finishes, external works, people and equipment, operational energy and water.
Project impacts over 60 year life cycle (assuming todays grid applied throughout)
