The best way is to educate yourself and do not overlook even the simplest conservation measure. Open windows account for a surprising amount of heat loss. An open window will suck out heat causing the heating system to work harder, leaving some spaces too hot while others loose needed heat. I always look for open windows in the residence halls. Sometimes I see them even in the middle of the winter.
Some halls are worse than others.
Look around, let me know where you see them. I'll give you a tally in a later newsletter. Do not block heaters. Allow air to circulate. One of the biggest causes of diminished heat is from reduced air flow to a heating unit.
