Why is “70/50” the gold standard? Should it be? Who decided? Does every gallery really need to be 70 degrees, plus/minus two? Does every storage space really need to be 50% humidity, plus/minus five? Is that a reasonable goal for most museums? At what cost? What’s the difference between “AA” climate control, and just “A”? How much energy could we all save, just by switching down one grade? Are artifact loan agreement climate requirements consistent, or is there room for improvement? Roger Chang (Principal, Buro Happold) joins host Jonathan Alger (Managing Partner, C&G Partners) to discuss “Rethinking Climate Control in Museums”. Along the way: Jackie Kennedy, root cellars, and a wooly mammoth. Talking Points: 1. Why 70 degrees? 2. Does it have to be the premier system?3. Reconsider those loan agreements.4. Knitting at the Renwick5. Don’t fight the building.6. “Fun Puzzles”7. Look in all directions.8.
