L. B. Marks, 103 Park Avenue, New York, has written a paper on “The Design of Illumination in the New York Carnegie Libraries.”[211] In this he advises consulting a specialist in every new problem.
In fact, with the complexity of functions in a large library, the need increases of seeking the advice of specialists on many points;—heating, lighting, ventilation, stacks, fireproof vaults are subjects where neither the librarian or the architect may know all the latest phases of the subject, and really want skilled information.
Champneys[212] recommends that oil lamps be kept lighted at stations all over a library, lest sudden failure of the electric light plunge it into darkness.
Heating and Ventilation
Except far north, these look out for themselves fairly well. As winter approaches, they ought to look out for each other. When you begin to plan for artificial heat, you can plan for ventilation at the same time.
In the smallest libraries, in wooded regions, wide fireplaces with wood fires make cheerful if not very even heat, and excellent ventilation up the chimney. In places where wood is scarce or dear, some sort of stove, like those used in groceries, depots, or schools, is next called into play. The interior view, for instance, of the Keene Valley Public Library (in Eastman[213]) shows such a stove at the right. The floor plans show a “wood-house.” In buying a stove, one of the makes with a jacket, on the furnace principle, can combine heat and ventilation best.
Fireplaces. We do not often use coal grates, but architectural features common in our libraries are wood-fireplaces. The excuse for introducing them is cosiness, cheerfulness, and ventilation. They are certainly cosy when a fire is kept up, but tending them requires a deal of time, the heat is rather irregular, the ashes are a bit blowy. Ventilation is no better by fireplace than through any other aperture, unless some sort of flame is kept up—a tiny gas-jet under the flue sometimes serves as an irritant. As usually built they cost money; and they usually interfere with wall-shelving which is needed. In small libraries with wall space to spare, where wood is the cheapest fuel, it may be well to have a fireplace with a fire tended by the townspeople; but in larger buildings fireplaces are generally nuisances, to be banished to the trustees’ room, if the architect wants one somewhere.
Champneys[214] thinks “open fires are to be avoided in all public rooms, because of unequal distribution of heat, of dust and noise, and of labor.” This is undoubtedly true of soft-coal grate fires, such as they have in England, but has Champneys ever seen the cleanly cheer of a country fireplace, full of six-foot logs? Few of us can afford them even in forest regions, but what an invitation such a glow offers in a rural neighborhood!
The next step beyond the stove would be the ordinary dwelling-house hot-air furnace; doubled or reinforced by a small one, if the house is a little too large to provide properly-gauged heat for all varieties of weather by one furnace.
