The compliance of water conservation aspects of clean water, wastewater, and rainwater management for residential buildings to support the green building concept

Water conservation is one aspect of the green building concept. Water conservation includes using a water meter to determine the amount of usage, calculating water use, reducing water use, using plumbing tools/features that can save water use, water recycling processes, alternative water sources, water reservoirs, and efficient use of water. The purpose of this study was to evaluate water conservation aspects in housing in accordance with the provisions of Greenship Homes version 1.0. This study uses a quantitative descriptive method by comparing housing water conservation conditions with Greenship criteria. Based on the results of the study, the evaluation results of the suitability of water conservation aspects in the Perumnas are 52% in total. In each of the criteria for water-saving fixtures, rainwater harvesting criteria, water-saving irrigation criteria, and wastewater management the value is below 50%. It is necessary to make improvements or make some efforts to be able to save and manage water wisely and effectively. These efforts include using a shower in every house, making a simple technology for harvesting rainwater, and installing a grease trap. With these efforts, the suitability evaluation of water conservation aspects in supporting the green building concept in house buildings can be achieved.
