When many people think that green building can only be applied to luxurious, large, high-rise buildings; Green Building Council Indonesia developed and introduced assessment tools for Interior Space (IS); where one of its main purpose is to assess its fit out activities, to make sure the implementations are environmentally friendly, from the floor, walls, ceilings, mechanical and electrical, using resources efficiently, minimizing environmental impact, and prioritize the user health and comfort. A room designed with attention to health and comfort of its users will generate a response in the form of positive behaviour, and will affect towards increased users’ productivity. For new buildings, the assessments are heavily dotted to the building owners and architects, whilst for IS, hold by the management of users and interior designers. Though the scope can be told minimum; the overall evaluation categories remains the same, departing from site selection, energy use, water, materials, indoor health, to the management issues; which should also being concerned.
People often pay less attention to the management viewpoint, seeing that the scale of IS’s activities are not as big as “unabridged building”, so the perception is that one activity inside a room will not bounce too much collision. This is unfortunate. No matter how small a space is, it remains a part of a building. The entire activity of the user will determine the success or failure of green building concept implementation itself. This factor greatly influenced by the factor of human involvement as one resource that plays a valuable role in the sustainability of a green building; for example, the user management who holds responsibility in the management of a room(s). Everything has to be considered from the design to the operational phase, including construction activity to development of training concept for employees as occupants (in, case). This means active and sustainable environmental education. Not to neglect the system for organization's management used to develop and implement environmental policy and manage its environmental aspects. Though it might be just only for a minor scale; still it will largely determine the sustainability of the space or room functions.
A need for cooperation between the acoustic and landscape experts, user management, interior designer, contractor, electrical mechanical technician, suppliers, and also occupants; are essential. It takes a good coordination over just between parties such as contractors and interior designers to gather information and decide every detail of planning and construction of IS, so as to produce an environmentally friendly design without compromising the aesthetics and comfort of its users, and also continue to consider ideas, concepts, and criteria established by the project owners and designers as outlined in the design intent. By the end of the day, the space or room(s) will have a long life cycle, reduced operational costs, and function optimally.
