Princeton University (NJ) recently installed water-saving toilets in two residence halls on campus. The new dual-flush toilets allow users to push the flush handle one way to use less water for liquid waste and another way to release more water for solid waste. Facilities Management installed water-saving shower heads as well.

The University of Texas at Arlington recently installed a 1000 square feet experimental green roof with the help of volunteers. The project included the installation of the roofing systems, irrigation, plants and about 30,000 pounds of soil.

The University of California, San Diego plans to install a network of up to 30 weather sensors on rooftops across campus. The data retrieved from the sensors will serve to provide an accurate display of weather conditions, which will allow for better control of the inside temperatures. The program could also help run the university irrigation system more efficiently and help determine the best placement for solar arrays.
