If a building is used twice for three hours each week, what is the best temperature for the remainin

The building is brick with wood framing and sheetrock. There is a copying machine, television, computer, and piano in the building. The temperature goes above ninety on a regular basis in the summer. In the winter, it freezes at night. On at least one occasion, the pipes froze. The temperature is generally set at forty in the winter. The air conditioning is cut off in the summer. What is the best temperature to keep the building in good repair and to protect the contents of the building? What is cost effective? I am worried about the extremes when we turn the air conditioning on to seventy when it is ninty. What kind of stress does this put on the units?

Keep the air above dewpoint in the winter this will keep it dry and condensation and mold will not come. If it is 90 in the summer set the aircon for 75. Set a frost stat so the pipes won't freeze up again. Frost stat means if the heat source is not going to work (automatically) sufficiently as it is really cold, that another heat source will kick in. You can also wrap the pipes with heat tracing tape and set that on (electrical) a frost stat and that will stop freezing up. It depends on what your budget is and what form of heating you have. Stress on what units? If it is 90 do you have a vent in the roof/ You could in theory have a temperature activated switch which turned on a ceiling fan and open a vent - hope this helps.
