- One of the aims of sustainable development is to reduce the emergence of the issue of the greenhouse effect, global warming, and climate change, including the issue of the natural resource crisis and the energy crisis. Jakarta is the center of government, the center of the Indonesian economy, so that many governments and private office buildings have been built, which have not all implemented the green building concept. Because the concept of Green Building is still considered a newly accepted concept in Indonesia and not many people know about it. As a form of implementing the green building concept in Jakarta, the DKI Jakarta Provincial Environment Agency as the agency in charge of the world's environment has committed to adapting the eco office concept to office buildings. It is hoped that the concept of green building can also be applied to the DKI Jakarta Provincial Environment Agency building. So, it is necessary to know the potential, problems, conditions, conformity with green building assessment standards according to current conditions and later submit several recommendations for increasing conformity with green building criteria standards if needed.
