The invention discloses a self-air-supply ash-filtering cooling silencing closable fireproof tall building with a solar warming water heater. An air supply system consists of a blind window with self-cleaned glass, a spraying water pipe, an air inlet main pipe which extends to an underground garage and then is sealed at a roof, air inlet branch pipes and valve covers which extend to each room, a stainless wind energy fan which extends from the underground garage to a place which is 6 m higher than the roof or a pipe orifice with a rain shade, an air exhaust main pipe of which the lower end is sealed, and air exhaust branch pipes and the valve covers which extend to each room. A heat preservation system consists of an internal door, windows, rolling gates which are arranged outside the windows, anti-theft fences, a heat preservation layer which is arranged on the external wall, an air relative isolation layer which is arranged outside the heat preservation layer, and a ceramic partition wall which is arranged outside the air relative isolation layer. Preferably, the solar warming water heater which is arranged on a shelf is connected with an indoor electric water heater and metal pipes under the floor to form a heat collection system. The invention has the advantages that: a livable environment which is dustless, quiet, warm in winter, cool in summer and fresh in air is created; and when a fire alarm is given, the doors, the windows, air inlet pipelines and air outlet pipelines are closed to eliminate a chimney effect, and with no need of escaping, people can wear gas masks, carry oxygen bottles and hold fire extinguishers to effectively extinguish fire.
