• Solar water heating systems for heating water in dormitories: About 160 solar collectors have been installed in Zweig Dormitories, Building 9, etc. The next stage – Matlam (Buildings 11 and 12). Heating with solar energy brings significant savings in energy compared with heating with diesel (which is the current situation).
• Space detectors: Space detectors, which turn off lights and ventilation when there is no movement of people, have been installed in the restrooms. A significant saving in energy – especially at night, holidays and weekends. So far detectors have been installed in about 26 restrooms, and it is intended to expand the project to all 300 restrooms on campus. Likewise, space detectors have been installed for the operation of air conditioners – here too the result is a significant saving in energy, for the same reasons.
• Energy-saving light bulbs: The campus is in the process of changing over to T5 fluorescent bulbs, which are more economical than those in current use.
• Economical heating: A heating system using central heat has been installed in Feldman halls – a chiller has been placed on the roof which serves only the halls, which saves about NIS 1500 for each hour of heating. The heating is not affected by the rise in fuel prices, and uses very little energy.
Reducing the use of pape
To encourage saving of printing paper, the price of two-sided printing in the library and computer center is lower than printing on one side only. Likewise, near the printers in the library halls and computer center there are stations for scratch paper for reuse instead using new paper.
Many restrooms on campus have water-saving facilities – such as motion detectors on faucets and urinals, the option to flush half the water in the container and more.
