About RapidLCA

For people and organizations seeking to lead action on climate change. We provide the RapidLCA app to optimize whole of life carbon, capital cost and operational expenditure of homes. The RapidLCA team are recognized for our integrity, teamwork, and passion for the environment. The app is praised for being easy to use, low cost and extremely flexible for all design approaches and geographical regions. RapidLCA is driving real low carbon outcomes and educating the market.

RapidLCA is a low carbon design app for buildings. It is available on any device with a web browser, and can be used as an app on Android and Apple iOS (see installation guidance here). RapidLCA utilises the power of Life Cycle Assessment (LCA) to calculate and optimise the environmental performance of your design. Life Cycle Assessment is the basis of the app because it is the most comprehensive and robust method of improving environmental performance. With careful attention paid to deliver a streamlined user experience and access to pre-built component libraries, we’ve also made Life Cycle Assessment fast and easy.

Pricing for the Planet

For the planet to truly benefit, we need the app to be widely used so that the cost of using the app is extremely low. Furthermore, we’re rewarding very low and zero carbon targets with a lower per-dwelling price. ‘Per dwelling’ pricing is the minimum cost of using the app per dwelling. Where RapidLCA is used by an organisation to manage a portfolio of buildings, set-up fees may also apply.

Per-Dwelling Pricing

We’re serious about saving carbon and the better your target the less RapidLCA will cost you. For example, a carbon saving of 25% or less will cost AUD 100 per dwelling, while a carbon saving of 100% will cost AUD 50 per dwelling.

Set-up Pricing for Organisations

RapidLCA is customisable and a setup fee may apply depending on the level of customisation you require. Types of customisation include:

  • Custom branding and web address to fully align with your project’s marketing strategy
  • Set targets across a range of environmental indicators beyond climate change
  • Limit or expand the list of construction components accessible to your users
  • Align the app to your approvals workflow and ensure applicants are uploading required documentation
  • Custom carbon factors for materials and energy
