NEAR ST. PANCRAS STATION (WHERE WE GET EUROSTAR TRAINS), THE BRITISH LIBRARY WORTHS TO BE VISITED NOT ONLY FOR ITS AMAZING COLLECTIONS, BUT ALSO FOR THE QUALITY OF ITS ARCHITECTURE. THE PICTURES ABOVE SHOW THE TWO TYPES OF SKYLIGHTS COVERING ITS ATRIUM. COMPARED TO SIDELIGHTING, TOPLIGHTING INCREASES UNIFORMITY OF THE DISTRIBUTION OF LIGHT, BUT ALSO INCREASES SOLAR GAINS AND HEAT LOSSES DUE TO CONVECTION AND CONDUCTION. CONSEQUENTLY, TOP FENESTRATION NEEDS TO BE EVEN MORE HIGHLY INSULATED THAN SIDE WINDOWS.
