Heating and cooling: Design temperature for a public library during the day?
I'd go for a dry resultant temp of 22C - radiant heating may allow a cooler air temperature to account for people being in outdoor clothing if it's just a lending library
17 degrees, with little peripheral reading booths heated to 21 or so for softer mortals. (Oh, and little posters on the wall advising them to jump up and down if they feel cold!)
Posted By: djhTricky. The reading room needs a very different environment to the shelf space.
Indeed, it would seem to depend on the layout of the building. Different areas might be put to different uses too, you don't want the children's section at the same temp and humidity as an archive.
3 things to consider, the best environment for books, the best for readers and the best for staff. Suspect all will be different. My experience of library readers is that they tend to be very small and run around a lot or very old and sometimes need to be taken out on a stretcher (D H Lawrence's legacy lives (or not) on). Light needs to be good, but not sunlight, humidity has to be controlled too, this changes the perceived temperature. When I worked in Judd Street, I used to trot along to the British Library for lunch. Never felt cold or warm in there, should have taken an iButton with me.
