Number of the Day: $2 Million

The United Nations' school-building arm will build a zero-emissions school in Gaza for $2 million. According to Green Prophet:

The design calls for a standalone building that will be constructed out of locally-sourced materials. It will be powered using solar energy, and cooling and heating will come from the ground. Excellent thermal massing will ensure that the building stays cool during hot summers, to facilitate a comfortable learning environment for 800 students. Rainwater will be harvested and recycled so that no clean water will be used for cleaning, irrigation, or plumbing.

It will house 800 students. If it's successful, it could serve as a model for 20 schools throughout the Gaza strip and similar facilities in Jordan, Lebanon and Syria.
