Go to the Million Cool Roofs Challenge prize site

The prize

$1 million will be awarded to the team that has developed the best sustainable and transferable model for rapid deployment of cool roofs in developing countries. The team should have deployed 1 million square meters of new, effective and durable solar reflective coating and/or materials on roofs of regularly occupied buildings in an eligible developing country between August 2019 and 1 December 2020.

Applicants were invited to apply to the challenge by 20th May 2019. The 10 best proposals were then chosen and each awarded a $100,000 ‘Boost Award’ to support them in reaching the final goal.

Who could enter the Challenge

Entrants to the Challenge must deploy cool roof solutions in an Article 5 Group 1 developing country as defined in the Montreal Protocol.

Teams could enter as a single organisation or as partnerships of several organisations, but as a single lead applicant that is a registered legal entity. Example lead applicant organisations could include local or national government organisation, university or research institution, international or local non-profit organisation, for-profit company or international organisation. Partner organisations could be of any type but at least one partner needed to be an in-country organisation if the lead applicant was based internationally.
