BREEAM Considerations for RIBA Stages 1 and 2

BREEAM Considerations for RIBA Stages 1 and 2

Successfully achieving a BREEAM 2018 UK New Construction rating for any proposed development depends on a number of key factors.

Chief among these are being mindful of minimum standards associated with the rating desired and addressing early RIBA stage requirements. Credits which have stage-specific requirements are outlined below

RIBA Stage 1 – Preparation and Brief

Considerations to be made within this stage include:

  • Whether a BREEAM Advisory Professional (AP) could be appointed. An AP provides detailed advice and guidance to keep the team on track to achieve the desired BREEAM rating. Up to three credits can be awarded for appointing a BREEAM AP.
  • Appointment of an Ecologist may be required, ecology credits can still be awarded without an Ecologist however far more credits can be achieved by appointing one as per the new route of ecological assessment.
  • Where laboratories are present client engagement is required in order to determine occupant requirements and minimise laboratory energy demands.
  • Methods to optimise the use of materials should be completed for RIBA Stages 1-5 inclusive.
  • A climate change adaptation strategy appraisal should be completed based upon a systematic risk assessment dentifying impacts of extreme weather conditions arising from climate change over the building’s projected life cycle.

RIBA Stage 2 – Concept Design

At this stage a Pre-Assessment meeting is required, if one has not already been undertaken, in order to agree a BREEAM rating. A target must be agreed in order to achieve BREEAM AP credits. Further credits have RIBA Stage 2 requirements, which must be addressed if the credits are to be targeted:

  • Consultations should be undertaken and documented appropriately between the design team and project delivery and third party stakeholders.
  • If credits concerning life cycle cost and service life planning are to be targeted an Elemental Life Cycle Cost plan should be produced.
  • At this stage consultation should also be undertaken with a Police Architectural Liaison Officer (ALO), Crime Prevention Design Advisor (CPDA) or other suitably qualified security consultant.
  • If low carbon design credits are being targeted Passive Design Analysis should be undertaken. This analysis must be based upon thermal modelling which demonstrates appropriate thermal comfort levels.
  • If renewable technologies are to be incorporated a Low and Zero Carbon Feasibility Study must be undertaken within this stage.
  • A life cycle assessment options appraisal of different superstructure, substructure and hard landscaping design options must be conducted. The results must be submitted to the BRE at the end of Concept Design, and before planning permission is applied for.
  • Measures to allow for disassembly and functional adaptation of different potential design scenarios should be considered with recommendations or solutions included within the design.
