Sustainable Buildings grants — page 5

Funding for low-carbon construction, deep retrofits and building performance. Active funders include UK DESNZ and the Social Housing Decarbonisation Fund, the US DOE, EU LIFE and Horizon, and local-authority retrofit procurement. Listed below are the open sustainable buildings grant calls in that landscape, taken from each funder's own notice and re-checked on every refresh.
Buildings funding is split between retrofit delivery, which is usually distributed through local authorities, housing providers and national schemes, and building-technology innovation, which comes through Horizon Europe, Innovate UK and the national energy agencies. Retrofit money is normally tied to a specified housing stock and a delivery partner, so the eligibility question is generally which stock rather than which technology.
This page lists open sustainable buildings grants currently tracked by Raise Lens — 339 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is sustainable buildings work rather than anything whose description happens to mention it.
The funders publishing sustainable buildings grants here include U.S. International Development Finance Corporation (DFC), Proparco, DEG (Deutsche Investitions- und Entwicklungsgesellschaft), among 2 others. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between funders than between individual calls.
Geographic coverage on this page spans GLOBAL-SOUTH, AFRICA, ASIA, LATAM, MENA. Eligibility is usually tied to where the work happens or where the applying organisation is registered, and the two are not always the same — worth checking before investing time in an application.
