Green infrastructure as imagined in Lego by Ferguson & Wilkins

Green infrastructure design challenge 2018 – call for entries

Closing date: 19 February 2018 at midday

CIBSE & UKCIP warmly invite you to take part in the third annual GI design challenge!

Supported by ecobuild, this challenge highlights the role of building-level green infrastructure, such as green roofs, living walls, indoor farms and gardens in creating sustainable indoor and outdoor environments. 

Design principles

Entries should consider what constitutes a healthy, productive and sustainable urban environment from both a building performance perspective, and as an improvement of surrounding public spaces. The designs should be effective now and as the climate changes.

The objectives of the design challenge are to:

  • Showcase opportunities to improve the liveability of our cities through GI
  • Demonstrate how GI can make an area an attractive place to work
  • Demonstrate how GI can contribute to improved health and wellbeing
  • Improve energy efficiency and climatic resilience.

Submissions must include design and operation solutions that enhance the indoor and outdoor environment, particularly those that:

  • Enhance the primary use of land and unlock additional benefits
  • Improve air quality
  • Reduce overheating risk
  • Improve flood resilience
  • Promote more sustainable transport, such as cycling and walking
  • Take account of likely future shortages in public water supply
  • Improve energy efficiency.


The challenge is open to everyone:

  • Individuals or teams
  • Students, qualified practitioners or researchers.

Entrants can choose to work at any scale:

  • Single building and its surrounding space
  • Larger, more formally linked spaces and developments
  • Any type of building
  • Current or past design projects
  • New or existing (refurbishments).

The scheme can be in any UK location.

In case no suitable building is available, the Clarence Centre at London South Bank University can be used. To request details of plans and energy profiles, please email


Two A0 posters per submission:

  • First poster – Presentation of the overall design strategy for the building and its surrounding urban environment
  • Second poster – Presentation of a detailed design solution for at least one building (in large developments) or selected indoor spaces in single building proposals
  • Calculations, drawings, and other material that provide evidence against the design principles
  • Rationale behind the choice of various green infrastructure elements or structures
  • Deadline for submissions of entries is midday on the 19 February 2018.
