Hong Kong’s CLP funds a window-film and fan pilot for about 500 households

CLP Power announced a HK$3 million Cool Home Pilot Programme on June 3, 2026, aiming to support about 500 disadvantaged households with sun-control window film and air-circulation fans. The funding comes from its Community Energy Saving Fund.

The utility described a referral-based program for eligible households in its supply area, working with district Care Teams and non-governmental organizations. Its announcement identifies Kwai Tsing, Kwun Tong, Sham Shui Po and Tuen Mun among the participating districts. This is a targeted community scheme, rather than a general rebate for every household installing film.

The combination matters. Window film addresses incoming solar energy, while the program also supplies fans to improve air movement. CLP’s current fund listing describes eligible measures as sun-control film or a window coating together with air-circulation fans. The published scope therefore should not be read as proof that every participating home receives an identical product.

CLP said previously completed cases showed indoor-temperature reductions of approximately 1–3°C from the window film. That figure is attributed to the utility; the release does not provide the full measurement protocol needed to apply it to another home. It is not a guaranteed temperature reduction or a measured result for all 500 intended beneficiaries.

The pilot provides a concrete example of residential window film being included in heat-relief assistance. The unresolved question is the program-wide outcome: the sources reviewed do not establish that all planned homes have been treated or quantify the electricity savings achieved across the pilot. Those results would be a separate development, rather than something the launch announcement can prove.
