Introducing The Million Cool Roofs Judging Panel

Meet the judges who will award $2M to spur community cooling innovations

Written by Helen Picot – Head of Strengthening for Efficiency and Access to Cooling, Kigali Cooling Efficiency Program

The Million Cool Roofs Challenge has announced its 10-judge panel.  These experts will select the entries that can most effectively scale cool roof technologies in developing countries which face risks related to insufficient access to cooling. With representation from six countries, the judging panel brings experiences from academia, NGOs, the public sector, industry and philanthropy. Get to know the judges and read their bios here.

The judges from the Million Cool Roofs Challenge are Hashem Akbari, Soffia Alarcon-Díaz, Lisa Bate, Walid Chakroun, Saurabh Diddi, Dan Hamza-Goodacre, Daniella Henry, Anjali Jaiswal, Nick Virr, and James Wolf.

The initial selection phase will choose up to ten teams who will receive $100,000 grants to deploy solar reflective coating and/or materials in an eligible country between August 2019 and December 2020. The final round of judging in 2021 will award $1 million to the team that demonstrates the best sustainable and transferable model for rapid deployment of cool roofs in an eligible country.

Climate change disproportionately affects the poorest and most vulnerable communities globally, hence it was important to us that judges brings best-in-class technical expertise and practitioner experience, as well as the developing country context that will help to identify the most promising approaches for delivering scale on the ground.

As the largest ever global effort to scale cool roofs, the Million Cool Roofs Challenge promotes solutions to address the climate impacts of inefficient electrical cooling and to improve quality of life for people living, working and studying in buildings without cooling.

The judges are passionate advocates for efficient, clean cooling solutions that can rapidly and sustainably scale to help reduce the access to cooling gap which leaves 1.1 billion people at significant risk from extreme temperatures annually.

The application window is live and will close on 20 May 2019 at 23:59 BST. Apply here here and don’t forget to carefully review all of the information on the Apply page before you submit your application. The judging panel looks forward to reviewing applications from around the world.
