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.
