Resilient London: confronting climate change
RightSizer is a sustainable MMC Strategy aspiring to the highest levels of environmental, social and economic sustainability. The RightSizer team asks ‘why reinvent the way we build with Modern Methods of Construction, if we don’t address the climate emergency?’
The project has evolved out of Meridian Water’s Placemaking with Purpose competition in response to the ambitious aims of Meridian Water’s Environmental Sustainability Strategy (ESS), and offers a vision and how-to guide to designing buildings for 2030 and beyond, heralding a low carbon world.
Conceived as a building system responding to the needs of senior living residents, RightSizer extends building longevity by enabling an active life with scope for reinvention — in other words, flexibility. The project team, in collaboration with Meridian Water, have expanded the functionality of the system to become a universal construction solution for multiple uses, including office, light industrial, parking and meanwhile uses.
The system comprises a long term ‘support’ layer, the superstructure, which has been designed for disassembly and reassembly. The support layer allows layout reconfiguration and optionality in terms of ongoing service riser locations. An ‘infill’ layer comprises non-load bearing partitions, panels and components, the ‘stuff’ making up the accommodation inside the ‘support’ system.
RightSizer is an emerging framework to encourage the construction industry to work together to respond to the biggest challenge of our time. The system sets out a roadmap to circular MMC, net zero buildings and a new construction ecosystem through the standardisation of component sizes, interoperable connection and component digital passports.
Meridian Water and Enfield Council have identified a land plot at Meridian Water Phase 2 to develop a pilot project using the RightSizer system. Through collaboration with the UKGBC, CIRCuIT, and Futureground, this project sets a precedent for achieving net zero on large-scale developments. RightSizer has been conceived to extend a building’s life beyond 100 years, a longevity underpinned by the inherent system flexibility that can accommodate various use scenarios over the years.
Set out by an ambitious client Sustainability Statement, RightSizer targets whole lifecyle embodied carbon emissions below 300kgCO2e/m2, closely aligned with LETI 2030 guidance.
'RightSizer meets these ambitions through applying circular economy principles, including:
