What would it take to transform today’s built infrastructure into tomorrow’s Super Low Energy buildings? The RE:Build Innovation Challenge brings together building owners, technology providers, industry partners and project financiers to answer this question. Powered by BCA and Hitachi’s Super Low Energy Building Smart Hub (SLEB-SH), RE:Build will see developers and building owners volunteer existing projects for innovative solution providers to model how their technologies could improve energy performance and bridge the gap between buildings’ current and potential future Green Mark performance. Getting the technology right is only half the equation. RE:Build will simultaneously explore the business case for retrofits – examining how improvements in energy and emissions performance translate into measurable economic value through operating savings, financing benefits, enhanced asset value, incentives, and emerging avenues for monetising green performance. Announced at the 2026 Singapore FinTech Festival, RE:Build will launch in 1H 2027 with building owners coming onboard this common innovation sandbox. Promising solutions and value-unlock models can subsequently progress towards validation, funding and deployment, with a view to demonstrating pathways for broader industry adoption. The ambition – developing replicable models for accelerating green building retrofits across Asia; and in doing so, demonstrating how the economics of going green can work for the owners investing in them.
