Abstract: Aiming at the problems of poor effect and low efficiency of water supply and drainage line layout of green buildings, a water supply and drainage line layout method of large green buildings based on time series prediction is proposed. Analyse the circular pipe network and route the water supply and drainage pipe network of large green buildings. Combined with the water consumption index, the water supply and drainage volume are calculated by using the land average sewage index method. Design flow distribution and pipe diameter according to water consumption and planned area. Determine the maximum layout spacing according to the layout principle of water supply and drainage lines. The time series prediction model is used to stabilise the maximum layout spacing and realise the layout of water supply and drainage lines of large green buildings. The results show that the proposed method has good layout effect and high layout efficiency.

Keywords: time series prediction; ARMA model; large green buildings; water supply and drainage lines; line layout.
