RIBA 2030

 
The RIBA 2030 Climate Challenge is a framework developed by the Royal Institute of British Architects (RIBA) to guide architects and the wider construction industry towards achieving net-zero carbon buildings by 2030. The challenge sets ambitious, science-based targets for reducing operational energy, embodied carbon, water usage, and health and well-being impacts, both in new builds and renovations. The guide defines a concise measurable set of eight sustainable outcomes that correspond to key UN Sustainable Development Goals and can be delivered on building projects of all scales.
 

1 Sustainable Outcomes Overview

1.1 Net Zero Operational Carbon

 
  • Metric: kWh/m2/y and kgCO2e/m2/year
  • The carbon dioxide produced as a result of the production and use of the energy from fossil fuels consumed for the day-to-day operation of the building or structure, including Low/zero carbon renewable energy technologies both on- and off-site, plus recognised offset schemes where essential. (As principally defined by CIBSE TM 54 Evaluating Operational Energy Use of Buildings at Design Stage, 2013, or Passivhaus PPHP.)

1.2 Net Zero Embodied Carbon

 
  • Metric: kWh/m2/y and kgCO2e/floor area m2
  • The carbon dioxide produced from the energy used in the extraction, fabrication and transportation from place of origin of the materials used in the construction, including recognised carbon offset schemes. (As principally defined by RICS Whole Life Carbon Assessment for Built Environment, 2017 )

1.3 Sustainable Water Cycle

 
  • Metric: m3/person/year
  • Analogous to operational carbon dioxide, the amount of mains water used in the operation of the building including the offset by use of greywater or recycled water to reduce mains water consumption. As principally modelled by England and Wales building regulations water calculator.
 

1.4 Sustainable Connectivity and Transport

 
  • Metric: kgCO2e per km per person per annum.
  • The purpose of this outcome is to measure the resultant carbon impact of the travel of occupants and visitors to and from site or building to a local transport hub or local retail and community facilities. As principally defined by BREEAM 2018 Transport Credits.
 

1.5 Sustainable Land Use and Bio-diversity

 
  • Metric: Increase in new flora or fauna species on site
  • Description: The intention is that this outcome should be used as a measure of actions taken to maintain, protect and improving the flora and fauna on site. As principally defined by BREEAM 2018 bio-diversity credits, Urban Green Factor, London Plan.

1.6 Good Health and Wellbeing

 
  • Metrics: Various metrics
  • This outcome includes key variables of internal occupant health and well-being, including Indoor Air Quality, Daylight, overheating, acoustic comfort, responsive controls, and physical contact to outside. As principally defined by CIBSE TM 40, 52, and 59, Good Homes Alliance overheating guidance and/or WELL Building Standard v2 Preconditions, 2019.

1.7 Sustainable Communities and Social Value

 
  • Metrics: Various metrics
  • The intention of this outcome is to measure the positive impacts of good placemaking on a local community. As principally defined by RIBA Social Value Toolkit, 2019.
 

1.8 Sustainable Life Cycle Cost

  • Metrics: £/m2
  • The ensure a holistic outcome with regards to economic sustainability, the intention is to use Government Soft Landings requirement for measuring operational costs of buildings. As principally defined by ICMS Global Consistency in Presenting Construction and Other Life Cycle Costs, 2019.
