Cost analysis resources

This collection of tools includes our own and external resources. <h4blue>STEP Life Cycle Costing Tool (Ontario)</h4blue>

The Sustainable Technologies Evaluation Program have produced a life cycle costing tool specific to Ontario. The tool is in a simple to use Excel format and is free to download.

<h4blue>CIRIA's BeST tool</h4blue>

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 on the right . Whilst the relative values may be useful for assessing options, the currency of this model is in GBP (£).

Sustainable Technologies Evaluation Program

Natural vegetation and vegetative technologies in urban settings such as: urban forests; green roofs; green walls; green spaces; rain gardens; bioswales; community gardens; natural and engineered wetlands and stormwater management ponds; and porous pavement systems. These systems are designed to provide multiple benefits, such as moderate temperatures, clean air and water, and improve aesthetics.

Refers to the conditions in which an organism lives and survives or the conditions in which an organism resides. These conditions can be described as aspects of a “physical”, “social” or an “economic” environment, depending on the perspective perceived by the observer.

A biological community, including humans and their natural environment.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.

Increases in groundwater storage by natural conditions or by human activity. See also artificial recharge

The inflow of surface water to a groundwater reservoir or aquifer.

The practice of intercepting, conveying and storing rainwater for future use. Captured rainwater is typically used for outdoor non-potable water uses such as irrigation, or in the building to flush toilets.
