EPI Tool

Sprout is committed to advocating the key role landscape architecture can play in delivering high quality Green Infrastructure and the contribution it can make to increasing the health and resilience of the urban environment.

Sprout has developed an Environmental Performance Indicator, or as we call it ‘EPI’ - a resource which models potential environmental performance outcomes across Green Infrastructure design and planning propositions. The EPI is designed to bolster capabilities in delivering high performing green active and passive open space.

Fundamentally, the EPI measures and communicates environmental outputs green open space propositions deliver via ecosystem services provided by trees.

Simple easy to read graphics clearly demonstrate the range of potential environmental outputs, enabling design development and design evaluation, as seen through an ecological lens.

The EPI was designed and built by Sprout with assistance from software engineers in Australia and the United States.

How EPI Works

How EPI Works

Sprout’s EPI tool can be applied at varying phases of design including;

Site Analysis - to assess existing site conditions and outputs,

Design or strategy development - to inform design refinement and options evaluation or

Stakeholder Engagement - to demonstrate to stakeholders performance benefits of good design and masterplanning.

Environmental data is extracted from a plan or drawing using Sprout’s CAD systems which organises data into metrics then displays it in very clear and legible graphic outputs.

The Outputs

The Outputs

The extracted environmental data is organised into the Sprout environmental performance metrics and displayed as easy to read bar graphs. The graphs enable an informed comparison of environmental performance rates across green open space design and masterplan options. Each bar on the graph represents a unique proposition with the orange being the existing (pre-development) site condition.
