Follow the Warwick Energy Trail to learn more about the University’s world-class research and technology to meet the global energy challenge.
The Energy Trail covers 16 individual points of interest across campus. It follows a circular route and you can join it at any point. The full route is 5km. The shortened route is 1.5km.
The University is committed to meeting the global energy challenge through both reducing the energy needs of campus and also through developing world-leading energy research. A number of points on the energy trail highlight where the University is being used as a test bed for the development of new energy technologies.
The convector heater
Glow in the dark signs
This is a convector heater. It draws cold air in at the bottom, heats it with electrical filaments and blows warm air out of the top. Electrical energy is converted into heat energy. There is also an electrical fan in there which converts electrical energy into kinetic (and sound) energy.
These double doors are a sort of air lock. There should always be at least one door closed between the inside and the outside. This means that warm (expensively heated) air does not rush outside quite so quickly when people enter or leave the building.
These lights convert electrical energy to light energy. The latest sort of lighting uses light emitting diodes (LEDs) which are much more efficient. This means that they waste very little energy as heat and so, for the same brightness as conventional bulbs, they are much cheaper to run.
This lift has to convert electrical energy into kinetic energy to rise up to the first floor. On the way down, gravitational potential energy can be released and converted into kinetic energy. (The motors have to work like a brake to slow the lift down.)
This glass roof means there is more natural light in the building during the day time. Also, as hot air rises, the windows at the very top of this structure can be opened to effectively cool the building.
This freezer has to use electrical energy to make a pump compress a gas inside a tube. When the pressure on the compressed gas is released , the temperature on the outside of the tube falls and the ice creams stay cold.
Glow in the dark signs
By making these signs out of a material that can store light energy, they will glow in the dark. This means they do not need to use a bulb and batteries and people can find the fire extinguisher at night in an emergency.
This is a lightning conductor. It can carry a huge amount of electrical energy safely down into the ground. If it was not able to do this, the building could catch fire if it was struck by lightning.
