RapidLCA

Core Features

RapidLCA applies more than a decade of Cerclos’ LCA experience to housing, wrapping complex methods in templated workflows that non-specialists can use. Built on the same underlying engine and modelling database as eTool, it focuses that power on fast, repeatable house assessments rather than open-ended project modelling. Against that background, some of its main features are:

• Simple inputs & preconfigured designs – Users supply general building specifications while preconfigured residential designs and algorithms, refined over many years, handle the detailed modelling, greatly reducing manual data entry and expertise requirements.

• Quick hotspot analysis – RapidLCA quickly highlights high-impact elements across the home’s full life cycle, helping teams focus on changes that matter most for net-zero housing targets.

• Net-zero optimisation tools – The app supports rapid comparison of materials, services, appliances, fittings and finishes so designers can iterate towards maximum carbon savings while balancing cost and performance.

• Compliant, auditable reporting – RapidLCA outputs reports aligned with international standards and designed to be auditable, giving confidence when sharing results with clients, buyers or regulators.

• Enterprise portfolio management – For organisations managing many dwellings, the platform offers project-level carbon-target configuration, upcoming performance tracking, preconfigured lots, validated templates, among other features.

• Accessible, flexible deployment – Available on desktop and mobile, RapidLCA adapts to different geographies, building types and user preferences.

Closing Insights

RapidLCA sits alongside eTool in the Cerclos product family, both built on an advanced LCA engine developed over more than a decade and aligned with international standards. Cerclos co-founder and chairman Alexander Bruce recalls that whole-house LCAs once took a month of manual calculation; eTool was created to speed that up, and RapidLCA now lets users complete an auditable house-level assessment in about half an hour. Where eTool offers open-ended whole-of-life modelling for buildings and infrastructure, RapidLCA narrows the focus to low- and medium-density housing, wrapping proven templates and datasets in an app that homeowners and non-specialist professionals can navigate easily.

Adoption is visible in case studies from Witchcliffe Ecovillage, the City of Vincent and Steffen Welsch Architects, as well as in practitioner stories such as The Sociable Weaver’s use of RapidLCA to compare designs against “business-as-usual” homes. For developers and councils, the ability to standardise assessments across housing portfolios and demonstrate net-zero trajectories to buyers, financiers and planning authorities is a key draw. As carbon regulation and disclosure expectations tighten, Cerclos’ shared engine, templates and audit focus help RapidLCA users keep pace without building in-house LCA teams. In summary, RapidLCA can serve as a practical entry point for organisations and individuals who want reliable life-cycle carbon numbers and clear optimisation paths for homes.
