Setting a New Benchmark for Sustainable Retail

Lidl Maynooth represents a significant milestone in Irish retail development, becoming Ireland’s first Net Zero Energy supermarket and setting a new benchmark for low-carbon retail construction.

Developed as part of Lidl’s long-term sustainability strategy, the project demonstrates how renewable energy generation, intelligent building services and sustainable construction methods can work together to create a highly efficient retail environment.

Working alongside our sister company, Lawler Sustainability, Lawler Consulting helped deliver a building that not only meets today’s operational requirements but provides a blueprint for the next generation of retail developments.

Delivering an Integrated Low-Carbon Solution

The project was designed around a simple objective — enabling the building to generate its operational energy requirements through onsite renewable energy while reducing both operational and embodied carbon.

Our engineering approach combined efficient building services with renewable technologies and sustainable material selection to maximise long-term building performance.

Key features included:

  • 575kWp roof and canopy solar photovoltaic system
  • High-efficiency building services
  • LED lighting with intelligent controls
  • Low-carbon construction materials
  • Sustainable timber roof structure
  • Water-efficient building services
  • Building designed to achieve an A1 BER

Working collaboratively with the wider design team ensured the sustainability strategy could be successfully integrated throughout design and construction.

Project Outcomes

  1. Ireland’s First Net Zero Energy Supermarket – the development established a new benchmark for sustainable supermarket design and operation.
  2. Renewable Energy at Scale – a 575kWp photovoltaic installation enables the building to generate its operational energy requirements onsite.
  3. Lower Operational Carbon – highly efficient building services and renewable technologies significantly reduce operational energy demand and carbon emissions.
  4. Reduced Embodied Carbon – lower-carbon concrete, sustainably sourced glulam timber and recycled materials were incorporated throughout the development, supporting circular economy principles.
  5. Future-Ready Retail Design – the completed store demonstrates how sustainability can be embedded within commercial retail projects without compromising operational performance or customer experience.
