 "Turn down heating in art galleries to cut carbon emissions, urges Tate director", News, page 11, last week, said that the Indianapolis Museum of art (IMa) allows temperature and humidity to fluctuate a little to either side of the global standard.

New ranges have been implemented with small monthly adjustments to achieve efficiencies in energy consumption without adversely affecting the condition of collection objects and loans.
