Stage 2 – Concept Design
Sustainability aims
To develop a Concept Design that embodies the underpinning Sustainability
Aspirations of the project with sufficient detail and analysis to be confident that
key strategies can be delivered in practice.
Checkpoints
• Confirm that formal sustainability pre-assessment and identification of key
areas of design focus have been undertaken and that any deviation from the
Sustainability Aspirations has been reported and agreed.
• Has the initial Building Regulations Part L assessment been carried out?
• Have ‘plain English’ descriptions of internal environmental conditions and
seasonal control strategies and systems been prepared?
• Has the environmental impact of key materials and the Construction Strategy
been checked?
• Has resilience to future changes in climate been considered?
Supplementary notes
• Set out the site-scale environmental design criteria (e.g. solar orientation,
overshadowing, SuDS, waste).
• Consider the design of the space between buildings as well as the buildings
themselves.
• Consider the need for and scale of private, semi-private and public external space.
• Establish maximum plan depths to achieve desired levels of natural ventilation,
daylight and view.
• Design for buildability, usability and manageability.
• Consider the impact of complexity of form on thermal performance, airtightness
and inefficient or wasteful use of materials.
