INTRODUCTION
In the last two decades, there has been rapid infrastructure development, the population has increased, the urban area has grown very high, and the need for clean water has increased greatly.
These conditions has impact on decreasing land functions in urban area because built infrastructure commonly ignoring environment value, which results in the problem of groundwater (Djaendi 2.
Land planning Aeis said to be sustainable if it has the lowest environmental impact, and is financially feasible, complies with development parameters and meets its development objectives.
Sustainable development is defined as development that meets the needs of the present without compromising the ability of future generations to meet their needs (Wheeler 2.
According to Wheeler .
, sustainable development is a development that improves the long-term health of human systems and ecology.
Jurnal Pengelolaan Sumber Daya Alam dan Lingkungan 13.
: 222Ae236 Frick and Suskiyatno .
stated that in Indonesia almost all buildings built since 1950 do not meet the requirements for sustainable development.
This is enough to show that buildings and structures are big in creating a balance of ecosystems, especially in environmental issues of air resources.
In this case, green building is a construction technology that is in harmony with nature, sustainable, environmentally friendly, and efficient in the use of natural resources.
Maintenance is an important step in maintaining the quality of a building, especially from the aspect of appropriate site development (ASD), energy efficiency and conservation (EEC), water conservation (WAC), and building and environment management.
Maintenance is a combination of various actions taken to maintain an asset, or repair it to an acceptable condition with reference to the standards set by the organization that performs maintenance (Corder 1.
The need for water in the city, especially in DKI Jakarta, is increasing over time in line with the increase in population and economic development.
Based on the latest data from the Department of Population and Civil Registration, the total population of DKI Jakarta in 2019 reached 11,063,324, including 4,380 foreigners.
Meanwhile, the area of DKI Jakarta is 662.
33 kmA according to Governor Decree No.
171 of 2007.
Water availability for both quantity and quality tends to decline because of water pollution, disruption of infiltration functions, changes in water catchment functions, and disruption of the balance of the subsurface hydrological system (Damayanti 2.
Therefore, it is necessary to make serious efforts to conserve water resources so that water has the opportunity to seep into the ground.
Water conservation, in principle, is the use of rainwater that falls on the ground and is managed as efficiently as possible with proper flow regulation so that there are no floods during the rainy season and sufficient water is available during the dry season.
Water conservation can be done by increasing the utilization of hydrological components in the form of surface water and groundwater as well as increasing the efficiency of irrigation use (Sallata 2.
The Chairul Saleh Building has also implemented an energy management program since 2016 for energy saving and efficiency through various programs and activities.
By installing renewable energy in the form of solar panels with a capacity of 34 kWp resulted in energy savings of up to 81,156 kWh or 5.
39% of energy consumption in 2016.
Increasing the knowledge and expertise of building managers in operating and maintaining buildings, as well as involving employees in energy-saving activities, resulted in energy savings of up to 308.
029 kWh or 20.
5% of energy consumption in 2016.
Energy saving efforts continued in 2019 with the same pattern relying on good operational patterns supported by the use of renewable energy and a building automation system (BAS) to run electrical equipment.
These efforts resulted in energy savings of up to 318,700 kWh or 21.
17% of energy consumption in 2016.
Entering 2020, the Chairul Saleh Building is also implementing ISO 50001 energy management system: 2018 since 2020.
Those excellent performance of energy conservation is in line with green-building principles.
However, itAos unknown the contribution to the assessment point of greenship.
Hence, an efficient and effective energy and water conservation system is urgently needed, based on the principles of benefit, balance, and sustainability, in order to maintain the continuity of the availability of resources in supporting sustainable development.
In this case, green building is a construction technology that is in harmony with nature, is sustainable, environmentally friendly, and efficient in the use of natural resources (Anbarci et al.
Indonesia already has green building rating system for new and existing buildings, namely in the form of a greenship developed by Green Building Council Indonesia (GBCI).
One of the important benefits of the green building concept is the climate and natural environment.
Green Building can not only reduce or eliminate negative impacts on the environment, but in most cases it has a positive impact on the environment at the building or city scale.
GBCI is an independent .
on-governmen.
institution that is fully committed to public education in applying environmental best practices (GBCI 2.
The green building concept can be applied to both new buildings and existing buildings.
Greenship of existing building from GBCI rating tools consist of 6 categories, namely appropriate site development (ASD), energy efficiency and conservation (EEC), water conservation (WAC), material resources and cycle (MRC), indoor health and comfort (IHC) and building and environmental management (BEM).
The four selected categories (ASD.
EEC.
WAC, and BEM) are the focus of the research because they relate directly to the quality Asmarani N.

Central Jakarta.
Researcher chose this location because the Ministry of Energy and Mineral Resources have energy audit program and won the Subroto Award in the Field of Energy Efficiency, especially for Category A "Energy Efficient Buildings" sub-category Green Buildings and Special Innovations.
Data Collection and Analysis Methods The assessment carried out refers to greenship rating tools of GBCI, namely a collection of several values or credits that determine whether the building deserves the title of green building or not.
The scoring system is divided into three types of criteria, namely prerequisite (P), credit, and bonus criteria (GBCI 2.
Chairul Saleh building is an existing building category that has been operating since 1980.
Assessment of the Chairul Saleh Building is carried out based on the GBCI Greenship for existing building version 1.
The level of assessment score achievement was categorized into 4 levels: Platinum if a minimum percentage 73% with score 83.
Gold if a minimum percentage 57% with score 66.
Silver if a minimum percentage 46% with score 53 and Bronze if a minimum percentage 35% with score 41.
In this study, the assessment focused on for 4 out of 6 categories, namely: Appropriate Site Development (ASD).
Efficiency and Conservation (EEC), water conservation (WAC), and Building Environmental Management (BEM).
The other 2 of greenship categories, namely Material Resources and Cycle (MRC) and Indoor Health and Comfort (IHC) were used to obtain total score.

There is a statement letter containing a commitment from management plan top management which includes: the existence of a procedure (SOP) covering: monitoring, saving targets, and an action plan for a certain period of time by the energy team .
Campaigns in order to encourage energy savings with a minimum of permanently written campaigns installed on each floor, among others in the form of stickers, posters, and emails .
Minimum building In addition to proof of commitment letter and action plan, energy performance one of the parameters that are easy to monitor is electricity IKE which is within reasonable limits.
Overall energy consumption in 2019 reached 1,180,890 kWh, in 2020 it decreased to 1,057,000 kWh, one of the contributing factors is that the number of employees working in the office is not as much as before the Covid-19 pandemic since the workfrom-home system was implemented.
In 2019, the building's IKE was below the 181.
68 kWh/m2/year standard.
In 2020, there was a decrease in the previous year, which was 162.
kWh/m2/year.
Because the IKE for electricity is smaller than the IKE for the reference electricity, which is 250 kWh/m2/month, this criterion has been fulfilled.
Optimized Calculation of the building IKE value which shows a value efficiency building below the reference standard IKE, every 3% decrease will energy performance get 1 additional point up to a maximum of 16 points.
Figure 3 shows a comparison of the Chairul Saleh Building IKE value in 2019 and 2020, the highest Chairul Saleh Building IKE is at 216.

The results of the sum of the total points obtained in all aspects of the green building show that the Chairul Saleh building managed to get 72 points .
39%) of its 117 maximum total points.
Based on the rating set by the GBCI greenship, the Chairul Saleh building is currently awarded a Gold rating for its ability to apply the green building criteria benchmarks to the building.
However, if you look back at the table, the acquisition value of water conservation Jurnal Pengelolaan Sumber Daya Alam dan Lingkungan 13.
: 222Ae236 is still smaller than energy conservation, which is much larger.
This shows that the steps implemented have not been maximal in their achievement.
According to the management, most of the water used is still dependent on the PDAM because the capacity of the rainwater produced is insufficient for use in the dry season, so it still has to be assisted by the PDAM.
To help the lack of water conservation aspects, in the Water Tap Efficiency category, you can try replacing conventional faucets with faucets that have an auto stop feature .
utomatic stop fauce.
so that when the faucet is not used, the faucet does not continue to release water and stops automatically.
According to Kubba .
, minimizing water can be done by using recycled water for flushing toilets and gray water for watering plants/irrigation.
To be more optimal in saving water, you should use recycled water from gray water waste.
In the Ministry of Energy and Mineral Resources, this processing has not been considered at all.
Site selection is also important in the assessment.
The location of the Chairul Saleh building of the Ministry of Energy and Mineral Resources is strategic, which is close to public facilities and easily accessible by land transportation, and has a building design that rises upwards.
This is supported by Kubba .
, who states that site selection basically emphasizes the reuse and restoration of existing buildings or sites.

also states that the location of the building must be in accordance with regulations, land use, and function, and must also pay attention to the development to avoid negative environmental impacts.
Regarding the initial location planning.

stated that minimizing the building footprint .

can be done by designing the building to rise upwards so that it has a smaller building footprint than the building design that extends to the side (Froeschle 1.
In addition, the use of air conditioning also requires a large amount of energy.
Research that has been done by Sugiyanto in Samudro .
in Surabaya is about the composition of energy use used in high-rise rental office buildings which in general are AC = 42.
Fans/Pump = 18.
Lights = 20.
Elevators = 9%.
Equipment = 12.
Samudro .
explained that it is known that the largest energy use refers to two types of value aspects, namely airing and lighting.
The largest use of energy is generated by the use of air conditioning and lighting.
The results of the study revealed that optimizing the light system through the use of natural light technology, the use of double-glazing technology on the building facade, and the use of energyefficient air conditioning systems can be used to maximize energy savings in high-rise buildings.
The gold rating of this building could be shifted to Platinum rating if there are some efforts to gain at least 11 points.
There is a possibility to gain 7 more points by increasing freshwater efficiency until 18% below the water consumption standard refer to SNI 03-7065-2005.
There is a possibility to gain 10 more points if building management could increase the efficiency of mechanical ventilation and air conditioning.
CONCLUSION
Based on the results of the assessment of the green building concept according to the GBCI that has been carried out, the conclusion that can be drawn in this study is that the Chairul Saleh Building has implemented 10 out of 16 points in the benchmark for the Appropriate Site Development (ASD) category.
Then in the Energy Efficiency and Conservation (EEC) category, 29 of the 36 maximum points were applied.
In the Water Conservation (WAC) category, they managed to get 5 of the maximum 20 points, while in the Building Environmental Management (BEM), they managed to get 11 out of 13 points, which were determined in the GBCI greenship rating tools for built buildings.
