Improving Energy Efficiency in College and University Campus

As the college or university campus is a vast decentralized system, it’s as bit difficult to manage the campus conserve energy and energy efficient. But by proper planning and intelligent initiatives, we can make create a sustainable and energy efficient green campus. Energy Efficiency of campus can be improved by implementing following techniques.

Class Rooms and Buildings:

  •  Minimizing the requirement of lights without reducing the quality of light using Architectural Lighting Techniques.
  •  Providing sufficient natural ventilation there by reducing the necessity of additional lights.
  • Install occupancy sensors to shut off lights when rooms are not in use.
  •  Installing Building Automation Systems (BAS) for campus buildings if there is possibility for lesser pay back periods for that campus.
  •  Pre-Cooling Air Conditioners in conjunction with existing Air conditioners to reduce energy consumption of Air conditioners and saves energy around 60% to 90% when compared to existing system.
  •  Cards used by students or faculty permit access to specific authorized areas. When integrated with the BAS, cards can also be used to trigger lighting and climate control. This is especially useful to save energy in areas that have unpredictable occupancy periods.

Laboratories and Administrative offices:

  •  We can use Smart power strips to Auto power cut off laboratory equipment they are left unused over a period of time.
  •  Installing Pc power saver software to manage the power saving options of computers which can turn off the monitors and puts them in to low power consumption when they are not in use of shorter time. It can reduce the energy usage by as low as 30%.
  •  Printers are typically left on for extended periods of time but are active only for a small percentage of that time. Turning off printers and photocopiers when you they are idle or not in use. We can use Smart power strips that are available in market to do this task automatically.
  •  There are some Printers with automatic “power down” features can reduce electricity use by over 65 percent.
  •  Preference should be given to use Laptops instead of desktops as they consume trice the power of laptops for the same task.

Hostels and Restaurants:

  •  Periodically recycling possible solid waste like aluminum cans plastic etc. that was generated inside the campus.
  •  Turn off coffee pots and similar appliances like water coolers when they are not in use. A typical coffee pot costs 4 cents per use and another 4 cents per hour to keep the coffee warm.
  •  Composting organic waste inside the campus to generate Methane gas.
  •  Using solar water heaters instead of Gas or Electric geysers
  •  We can use Food Management Software to help us keep track of student consumption, so that we can more accurately forecast the amount of food to prepare. This helps to serve students with the foods they require, while ever reducing the amount of food that gets wasted.
  •  We can convert waste oil that was generated while cooking food in to Bio diesel or bio fuel which in turn can be used to run diesel generators in campus or to cook food by burning.
  •  Induction, convection, and pressure cooking should be adopted for cooking which use less energy than conventional ones.

Overall campus:

  •  Installing capacitors at supply end to improve power factor of whole electrical system of campus.
  •  Using bicycles and replacing conventional diesel buses/vehicles with hybrid or electric buses/vehicles for inter campus transportation.
  •  Periodic energy audits and reports of recommendations.
  •  Usage of bottled water inside the campus should be minimized and use filtered water instead.
  •  Ionators can be used to clean rooms with Zero Chemical Usage, saving money, reducing pollution, and making a safer environment for faculty and students.
  •  We can use solar powered waste disposable units in place of Waste bins.
  •  Creating awareness among students and faculty is important to adopt campus sustainability techniques for continued implementation of energy minimization on long run.
