Design Parameters of Residential Building for Improving Performance of RHS: Evidence from Fuzhou, Fujian Province, China

Abstract

Rain water harvest system (RHS) has been widely adopted in residential buildings and was proved to be an effective approach for reusing rainwater as the replaceable resource of domestic water. However, due to the complicated design procedures and confusing design codes, the insufficient cooperation between architects and RHS engineers leads to poor performance of RHS and also restrictions on the extensive utilization of RHS. The majority of previous studies take little consideration from the view of the architect while the later shows much concern on the operational parameters of building design. For more effective cooperation, the implementation of RHS in residential building should be integrated in the stage of primary design. Therefore, we are intended to propose a series of Cooperative Design Parameters (CDP), which are integrated with Residential Building Design (RBD) and RHS Design (RHSD), for the purpose of improving the performance of RHS in residential buildings.
