Methods in water conservation as part of green building rating tools in Indonesia - Case study: Design of integrated classrooms building in Universitas Negeri Malang, Indonesia

Abstract

Under support from the Islamic Development Bank (IDB), Universitas Negeri Malang (UM) is going to develop two new integrated classroom buildings, which consist of not only classrooms, but also seminar rooms, laboratories, lecturer's rooms, educational studios, and auditoria. As an approach to make the buildings gaining the green building certificate, the rating tools are selected from the Green Building Council Indonesia (GBCI). One of the parameters used in the rating tools are how the buildings manage its water resources, as rated from water conservation methods and techniques. The purpose of the research is to analyse the design of the new buildings, particularly the methods in water conservation to be rated in greenship for new building design. The data are obtained from all detailed engineering design documents of the buildings, which include working drawings, detailed specifications, and bill of quantity. By using parameters stated in the GBCI's rating tools, methods of water conservation are analysed to gain the targeted score for fulfilling the specific level of greenship.
