You laugh -- But!
My father was a Chemistry professor at a small college in West
Virginia. In the late 60's they designed and built a new Science
building, which opened in 1971. In the mid-70s, during the energy
crisis, the college decided to try and save money by turning off all
lights in the building at night. This was OK until winter came.
They found that the heating system in the new building was running
100% of the time overnight, but the building temperature was still in
the low 60s in the mornings. It turns out that the architects of the
building had factored the heat output of all the florescent lighting
in the building hallways. In fact, the lights were positioned just
below the air returns for the HVAC system for this purpose.
It was actually a brilliant bit of engineering.
So, they ended up leaving all the lights on in the winter.
