Water Use Efficiency Strategy for the Universitas Trisakti FTSP Building

EasyChair Preprint 15208

Abstract

Buildings play a significant role in green development. FTSP Building at Universitas Trisakti aims to implement Green Buildings. Water efficiency contributes 13% to the green buildings criteria. To determine efficiency and strategies for improving water usage, water balance calculations were performed using the Ministry of PUPR Water Balance Software v2.6. Strategies were tested through 72 simulations, each replacing a component to identify the most impactful factor on the FTSP building's water efficiency. The water efficiency of the FTSP building aims at conserving PDAM water resources. The simulations revealed that the most influential components for water efficiency in the FTSP building are the water system and faucets. Adopting a system that uses rainwater and treated used water for non-potable needs, recycling black water for toilets/flushing, and installing water-saving faucets on FTSP can reduce the water efficiency of PDAM from 4% to 78.9% on dry days and 100% on rainy days if supported by various factors. The assessment points increased from 9 to 15 out of 22 points. Further testing is needed to accurately implement this strategy in the FTSP building.
