With the
addition of the new Bachillerato/IB building has come a new colour scheme for
the walkways outside the laboratories and going down to the main gate. They say
it is in keeping with the colour scheme of the new building, but is there a
more environmental reason at play?
Students
have said that the surface is too bright and they find it difficult to see. Students
and teachers using these walkways have to squint on very sunny days making us
all look a little more stressed than we would normally look.
So how is
this surface having an environmental impact?
The fact that
the surface is reflecting the light (hence very bright) it means that not as
much light is being absorbed and converted to heat. The surface is therefore
cooler meaning the air above is also cooler. This reflected light should
hopefully head off into space and not affect the planet again. The previous
surface was red in colour and used to absorb a lot of sunlight energy
converting it to heat. This heat would be radiated as infra-red (IR) radiation
that would heat the air making it warmer outside the labs. More importantly,
this heat would also be trapped by greenhouse gases in the atmosphere and
increase greenhouse effect and global warming which is a very serious problem
we are currently facing. So is Oak House reducing global warming by painting its
walkways a very light colour?
A test of
the difference in the temperature of the surfaces is to check the light surface
and red steps outside the labs. Come and feel the difference yourself to see!
