THE Institution of Heating and Ventilating Engineers of 12, Russell Square, W.C.I, now issues a Journal, the first number of which was published in March. The object of the Journal is to keep its members in touch with the latest practice both at home and abroad and in particular to give them the latest results of the research work being done on the subject. In the first issue, an important paper by E. Herring is published giving the methods that have been employed for warming and ventilating the Masonic Peace Memorial building in Great Queen Street, London, W.C.2. As many masonic meetings will be held there, it was necessary to use special precautions so as to eliminate the possibility of sound being transmitted from one room to another. All the fans, motors, and machinery had to run silently and it was necessary that the rate of ventilation and the templerature of each room should be controlled from the engineer's room, so as to obviate the necessary of the engineering staff having to enter any ‘lodge’ room. The ‘lodge’ rooms are designed to give a mazimum supply of conditioned fresh air equivalent to 1,750 cub. ft. a head an hour. A refrigerating plant is installed for cooling and removing the moisute from the air when necessary. In winter hot water is suppled by steam-heated storage calorifiers thermal storage system is employed. Steam for all purposes is generated by four steam boilers working at a pressure of 100lb.;er sq. in. and capable of evaporating 7,000 lb. per of water an hour at 212 °F. Storage for the oil fuel is provided by five cylinders having an aggregate capacity of as sixty tons.
