Electric baseboard heat

[Rich Merlino]

Dear Esteemed BP Community,

I have recently purchased several buildings in Massachusetts that are very poorly insulated and use electric baseboard heat.  I am working with a program called Mass Save to improve the insulation, and I intend to help the residents put plastic on the windows and use door insulators.  

A major overhaul of the heating system is not feasible this week.  Until I can implement some long-term solutions, what quick and simple measures could be taken to reduce the residents' electric cost?
