A Mexican hotel chain is using our DIY Packet to coat rooftops white. This year, three hotels with 859 rooms each will get shiny new white rooftops. White roofs are catching on Mexico, which is part of Global Cool Cities Alliance launched in 2010 with support from the International Energy Agency. We'll check in with our southern neighbor to get pictures of their work and updates on their progress.
