20-22 Ropemaker Street Achieves World Leading Sustainability Standard with BREEAM ‘Outstanding’ Certification

20-22 Ropemaker Street, a new next-generation office building in London’s vibrant Moorgate, has been awarded BREEAM 2018 New Construction ‘Outstanding’ Certification – the highest available rating under the latest BREEAM standard, with an overall score of 87.6%. This recognition also underscores the commitment of developer Old Park Lane Management (OPLM) to environmental stewardship and sets a new standard for sustainability and long-term performance in the city.

The achievement was made possible through meticulous planning, in order to ensure a comprehensive sustainability strategy was embedded in the project’s DNA from its inception. Hilson Moran was appointed by OPLM to lead on sustainability from RIBA Stage 1, helping to prioritise sustainable strategies from the start, with the aim of not only meeting but surpassing sustainability targets. This strategy was enabled by a dedicated project team comprising of architect Make, development manager CO-RE, principal contractor Skanska, Hilson Moran as sustainability and MEP, Waterman acting as structural engineer and ecologist, and WT Partnership as Cost Manager.

The BREEAM New Construction standards, administered by BRE, provide a framework to deliver high performing, and sustainable, newly built assets that support commercial success, whilst also creating positive environmental and social impact. The standard uses a common framework and is an industry leading sustainability standard allowing for consistency and comparability between schemes at a national level.

Originally registered under the BREEAM 2014 scheme with an initial goal of achieving an Excellent rating, the Ropemaker team saw an opportunity to aim higher with the launch of the BREEAM 2018 scheme in March 2018. Securing a higher rating in the later design stages of a project is not simple – particularly on an updated standard – but the holistic approach to sustainability and enhanced strategies enabled the team to secure the upgrade to ‘Outstanding’ at design stage in August 2020.


The BREEAM certification process evaluates 10 core aspects, covering Management, Health and Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use and Ecology, Pollution and innovation. Highlights from the assessors include:

Management: Full credits achieved, plus an exemplary credit for responsible construction management. Comprehensive consultation, and sustainable construction practices commended, including all timber sustainably sourced to FSC standards.

Health and Wellbeing: Ensuring indoor comfort with best practice acoustic performance and air quality with a best practice ventilation rate. Comprehensive façade analysis utilised to achieve thermal comfort for both present day and future climate scenarios.

Energy: Implementing a fabric-first approach, efficient lighting, and monitoring systems to optimise energy performance and support future renewable energy connection capability, if a heat network becomes available. A comprehensive metering strategy was implemented to enable ongoing smart monitoring.

Transport: Full credits achieved, offering class-leading cycling facilities including maintenance station, electric vehicle charging and live transport displays.

Water: Utilising low-flow fittings helped enable a 51% reduction in water consumption compared to BRE baseline, alongside greywater recycling and efficient irrigation systems.

Materials: Prioritising responsible sourcing through a comprehensive procurement strategy, durability, and efficient use of materials.

Waste: Implementing comprehensive waste management strategies, achieving high diversion rates from landfill, and designing for disassembly.

Land Use and Ecology: Enhancing biodiversity, implementing habitat creation measures, and ensuring long-term ecological maintenance.

Pollution: Employing low-impact refrigerants, leak detection systems, and mitigating light and noise pollution.

The achievement of BREEAM 2018 Outstanding Certification for 20-22 Ropemaker Street represents the cumulation of many years of effort, only made possible by a consistent commitment to the vision across the entire project team. The project’s success demonstrates that high-performance buildings can be both environmentally responsible and economically viable for the long-term.
