Cost analysis resources
This collection of tools includes our own and external resources.
STEP Life Cycle Costing Tool (Ontario)
The Sustainable Technologies Evaluation Program have produced a life cycle costing tool specific to Ontario. STEP built the tool after evaluating LID practices and design scenarios for input costs, maintenance requirements, rehabilitation costs and practice designs relevant to Canadian climates. The tool is in a simple to use Excel format and is free to download.
Green Infrastructure Optimization Tool (Great Lakes)
The Greater Lakes Green Infrastructure Optimization Tool gives a preliminary assessment of green infrastructure options. Land-cover types (and technologies) include: Existing and proposed buildings, existing and proposed paved parking areas, walkways and roadways, open space, pasture, meadow, brush, woodland/grassland, woods and bare soil.
Green Values Stormwater Toolbox (Great lakes, USA)
A free tool for evaluating the costs and benefits of green infrastructure. It is based on the hydrology of the Great Lakes region, and produced by the Center for Neighborhood Technologies, a non-profit organisation in the USA.
United States Environment Protection Agency (USA general)
A collection of resources from the Green Infrastructure team at the US EPA.
CIRIA's BeST tool (UK)
A tool which monetizes Ecosystem Services (ESS) and Triple Bottom Line (TBL) criteria to assess LID options (described as Sustainable Drainage Systems, SuDS). The tool guides the user to consider some or all of the co-benefits listed below . Whilst the relative values may be useful for assessing options, the currency of this model is in GBP (£).
- Air Quality
- Biodiversity and Ecology
- Building temperature
- Carbon sequestration
- Economic growth
- Enabling development
- Flexible infrastructure
- Flood risk
- Groundwater recharge
- Human health
- Pumping wastewater
- Rainwater harvesting
- Treating wastewater
- Traffic calming
- Water quality of receiving water
- Trees for costing tools particularly focused on street trees and urban canopy.
- Rainwater harvesting for advice specific to RWH systems.
- Managing Costs and Containing Risks using the One Water Approach
