Envest2 and IMPACT


IMPACT is a specification and database for software developers to incorporate into their tools to enable consistent Life Cycle Assessment (LCA) and Life Cycle Costing (LCC). IMPACT compliant tools work by allowing the user to attribute environmental and cost information to drawn or scheduled items in the BIM. Put simply, IMPACT takes quantity information from the BIM and multiplies this by environmental impact and/or cost ‘rates’ to produce an overall impact and cost for the whole (or a selected part) of the design. The results generated by IMPACT allow the user to:

  • analyse the design to optimise cost and environmental impacts.
  • compare whole-building results to a suitable benchmark to assess performance, which can be linked to building assessment schemes.

The overall aim of IMPACT is to integrate Life Cycle Assessment, Life Cycle Costing and Building Information Modelling.

Envest 2 is a software tool that informs the design process to deliver buildings with low environmental impact and whole-life cost. It makes explicit the environmental and financial trade-offs in the design process, allowing the client to optimise the final design according to their priorities.

Envest is web-based allowing design teams to store and share information in a controlled and accessible way, enabling benchmarking and design comparison. Envest is based on Environmental Profiles data and certified Environmental Profiles data for manufacturer's products can be used within Envest to model impacts within a building.
