Vancouver’s Light House expands circular construction accelerator to accelerate low‑carbon building solutions in BC

Vancouver’s Light House has broadened the reach of its Circular Construction Accelerator (CCA), adding 17 British Columbia companies to a 2025 cohort focused on scaling circular and low‑carbon solutions across the built environment.

According to Light House, the new cohort includes firms developing low‑carbon and bio‑based building materials, modular and prefabricated construction approaches, and deconstruction, material‑reuse and waste‑recovery systems , “circular‑tech” tools intended to make lower‑carbon practices easier for builders to adopt at scale. The organisation says new supply‑chain pathways, including prefab, reuse, recycled aggregates and bio‑based materials, are expanding fastest in BC.

“We are proud to support this cohort of innovators whose work represents the promise of a more circular and regenerative future,” Gil Yaron, managing director of circular innovation for Light House, said in a statement. “Each company shows what’s possible when we rethink how buildings, materials, and systems can support healthier communities and lower‑carbon outcomes. Light House is committed to backing the visionaries who are helping define the next generation of Canada’s built environment.”

The CCA is designed to give early‑stage and scaling companies tailored advisory support, introductions to investors and industry partners, and pathways into market , services that industry stakeholders say are critical to converting pilot‑scale technologies into project‑ready solutions. According to Light House and programme materials, participants receive mentoring, brand visibility, access to a circular investor network and scaling resources intended to reduce time to adoption in construction supply chains.

The expansion is backed by federal regional development funding: Pacific Economic Development Canada (PacifiCan) announced in January 2025 that it had invested $1,083,672 to support Light House’s Circular Innovation in the Built Environment Accelerator Program as part of a broader $17 million initiative to spur business growth across BC. The department framed the funding as part of efforts to accelerate growth of green building companies in the province by providing mentorship, market insights and workshops tied to low‑carbon materials and circular practices.

Light House’s CCA sits alongside other practical market‑facing interventions the organisation has launched to reduce construction waste and strengthen local material loops. Earlier in 2025 it rolled out the Building Material Exchange (BMEx) Marketplace , a free, business‑to‑business platform built on the Rheaply system , to enable listing and acquisition of excess and salvaged building materials in Vancouver Island and surrounding markets. Light House and local partners have said the marketplace aims to lower waste‑management costs for donors, cut materials costs for recipients, and reduce landfill diversion from construction activity.

For construction firms and manufacturers grappling with decarbonisation, the combination of market infrastructure and accelerator support addresses two common barriers: predictable supply of circular products and practical, project‑level integration. Industry groups and construction practitioners have increasingly emphasised modular and prefabricated approaches, plus material recovery and reuse workflows, as efficient levers for lowering embodied carbon and shortening schedules , outcomes that the CCA cohort’s focus areas mirror.

Light House said the CCA is free to participants and opened applications for the 2025–26 cycle earlier in the year to BC‑based construction companies, manufacturers, designers and service providers. The organisation also scheduled a practical webinar on December 10, 2025 with Chandos Construction and Green Island Builders to demonstrate on‑site waste management and circularity systems; the session was promoted as a vehicle for sharing scalable practices and lessons learned from project delivery.

While Light House and its partners present the CCA as an accelerator of supply‑chain change, the real test for the cohort will be measurable uptake: conversion of pilot products to specified materials on live projects, demonstrated reductions in embodied carbon and waste, and the emergence of repeatable commercial models for reuse and prefab. Government funding and marketplace tools can lower barriers, but industry adoption will depend on procurement practices, contractor capabilities and clients’ willingness to accept novel materials and workflows on mainstream projects.

For practitioners involved in industrial decarbonisation, the CCA’s expansion highlights a pragmatic route to market development: combine targeted public investment, marketplace infrastructure and direct engagement with builders to move circular materials and methods from demonstration into routine specification. According to Light House, that is the objective underpinning its work in BC , a region the organisation argues is moving fastest on new circular supply‑chain pathways.
