Hi, Charlie;
A two degree F. drop in temperature is negligible in it's effects on artefacts; most Loan Agreements I've seen from even national collections allow this much fluctuation daily for artefacts on loan to other institutions.
You should be aware, though, that dropping the temperature will raise your Relative Humidity; you should monitor that, if you are able. Although, for the change you're contemplating, I don't believe you'll experience a significant RH variation, either.

I have a question regarding keeping a constant temperature/RH in exhibit areas. Our main museum is housed in a mid-19th century Court House (2 floors) and currently we keep the temperature between 68-72, usually right at 70, although some galleries run much higher temps than others. However, we have been instructed by our Dept Head (we are a City bureau) to reduce our energy consumption to cut our costs - obviously lights can be turned off when we're not open, but the temperature controls must remain on for the welfare of the artifacts on exhibit. So my question is would there be any harm in lowering our temperature by two (2) degrees, for a target range of 66-70?
