Abstract

This study focuses on the public building in Indonesia that has implemented an energy management system compliant with ISO 50001 standard. The main objectives of this study are to review the implementation of the energy management system in the building, highlighting the main aspect of the ISO cycle deployment and key lessons learned for further dissemination. We performed the study of the implementation of energy management in the building sector based on the ISO 50001 framework that aims to enhance an organization to pursue the continuous improvement of energy management with a systematic approach. Implementing the plan, do, check and act cycle of the ISO’s framework, it is found that the management keeps a strong commitment to continuous improvement. As part of the energy management system cycle, an Investment Grade Audit (IGA) was performed in 2018. Implementing the IGA recommendation, both passive and active designs have been applied in the Slamet Bratanata building. Active design strategies that have been implemented include building automation system utilization, chiller and lighting replacement and Energy Monitoring System (EMonS) application. Implemented passive designs include windows film installation and an efficient room redesigned for optimizing natural light. To implement the ISO 50001 Energy Management System in the building, the energy management team has also held various activities. It includes developing Standard Operating Procedures, appointing a Person in Charge on each floor, conducting capacity building and performing an energy efficiency campaign. It is estimated that the energy management system has succeeded in reducing energy consumption by 613.188 kWh (in 2018–2020) and the Energy Efficiency Index by 129.06 kWh/m2/year in 2020. Furthermore, management energy implementation also reduced greenhouse gas emissions by 539.60 tons of CO2 equivalent. This study provides a reference for energy management in another building for improving its energy performance.

Abstract

Indonesia intends to increase the renewable energy ratio to at least 23% from the energy mix generated by 2025. This target is also in line with the Paris Agreement that Indonesia ratified in October 2016. However, renewable energy capacity has not been significant, as 11.38% of the total on-grid power capacity (MEMR, 2021). More than 90% of renewable comes from hydropower and geothermal, and only a limited capacity comes from wind and solar energy. On the other hand, wind and solar energy potential are enormous for energy generation in Indonesia. One of the barriers that hinder the use of both is their intermittent nature so that they are not economically profitable and can disrupt the existing power grid. Energy storage systems (ESS) can reduce this intermittent problem as frequency regulators and voltage support to the grid. This paper reviews the potential and challenges of energy storage and renewable power generation, especially wind and solar power. This paper also outlines lessons learned from energy storage systems that have been implemented and are still under development. The discussion focuses on the types of energy storage suitable for applications in Indonesia.

Abstract

Energy and climate problems that occur encourage the intensification of energy use efficiency, one of which is in buildings. The building sector is the largest contributor to energy consumption when compared to other sectors due to the need for comfort in life, including to regulate air temperature, ventilation, and artificial lighting. Window innovation as a building component leads to adaptive smart windows technology that has energy saving features. The use of these windows is attractive because they are designed to adapt to changing environmental conditions to minimize large heat losses by adjusting their transmissivity and conductivity. Various types of smart windows have developed, one of which is electrochromic technology as dynamic glass technology which has been widely used as smart windows in commercial buildings. Several studies have shown that its use in buildings has been shown to save energy consumption in buildings through the HVAC and lighting aspects. However, in today's technology, its performance still requires external power to adjust their optical conditions. Therefore, the innovation in developing electrochromic smart windows technology that is integrated with photovoltaic technology is an interesting thing to do. The combination of the electrochromic solution with photovoltaic Si-TFSC placed on a glass substrate provides promising optical performance and energy benefits. The integration of electrochromic and photovoltaic devices provides better efficiency in energy saving, because photovoltaic and electrochromic devices can achieve electrochromic layer discoloration without an external power source. Given the photoelectric and optical modulation properties of electrochromic photovoltaic windows that can function as solar cell modules as well as powered smart windows on their own, this technology has a major advantage in applying sustainable energy to buildings. In its application in buildings, to improve device performance, the control system can be applied by adjusting environmental conditions according to the sensor system readings to obtain better device performance.

Abstract

The exploitation of natural resources affects environmental damage and does not comply with environmental licensing. The purpose of this article to find out and understand related to development through investments that can achieve people's welfare, and analyze the reorientation of sustainable development principles in investing by utilizing pro-environment natural resources. This result is reorientation the principle of sustainable development should be done by integrating the activities of the investment policy of natural resources into the economic system and environmental based budget. The conclusions are first, the perspective of the Indonesian government in development through investments isn't directly proportional to the welfare of the people. Current developments tend to the developmental and anthropocentrism paradigms; and secondly, reorientation on the principle of sustainable development since changing the government's perspective on development using an ecocentrism paradigm, and integrating natural resource investment activities into the economic system or environment-based budgets.

Abstract

Having great potential, a mechanism that can leverage private involvement in energy efficiency deployment should be developed in emerging markets such as Indonesia. This study aimed to formulate an implementable financial innovative scheme for leveraging energy efficiency deployment in the country. Scrutinizing relevant studies and interviewing relevant stakeholders such as the Ministry of Finance, Ministry of Energy and the Financial Institution, we formulated a blended financial scheme for an energy efficiency project. Main stakeholders will include the scheme, including fund facilitator, trustee, custodian bank and energy user/energy service company. In our proposed scheme, Indonesia Environment Fund (IEF) is obtained the fund from the fund facilitator. IEF will act as a trustee that delivers funds for the Custodian Bank. The bank will disburse the fund to the feasible energy efficiency project or through an energy service company. In this scheme, since banks get lower interest rate funds from the trustee, they will disburse the fund to the customer with a lower interest rate than a commercial rate. Consumers utilize the fund for their energy efficiency projects. Utilizing a proposed scheme to an energy efficiency project case study, it is found that the proposed scheme potentially reduces the interest rate and leverages the project viability in a certain condition. Doing the sensitivity analysis by comparing interest rate and IRR (Internal Rate of Return) in several loan periods, we found that the shorter period of the loan and lower interest rate can improve projects feasibility. For instance, simulating a 5-year loan, it is found that reducing the interest rate from 12% to 7% could improve up to 2% IRR of the project case. Therefore, the scheme can catalyze private-sector investments mobilization for energy efficiency deployment in the country. Furthermore, it can support the country's energy security enhancement.

Abstract

Energy plays a strategic role in human life today. In this case, energy is an interdisciplinary concept from the concepts of science and the environment to global social problems. One aspect of energy development is energy conservation, where efficient and rational use of energy is carried out without reducing energy use performance. To increase public awareness and participation on energy issues, especially those related to energy conservation, it is necessary to increase knowledge about energy in the wider community, one of which is through energy literacy. This is because knowing energy will empower people to make wise decisions and take responsible action regarding energy use. Energy literacy here can be obtained through formal and informal education. This study investigates the condition of energy literacy in Indonesian society in general through a sampling method, and it is found that the level of energy literacy in Indonesian society is on a moderate scale, but it is still not enough to reach the expected level of energy literacy, while the energy literacy level is less. Energy literacy and energy conservation will also be increasingly hampered. Therefore, it is hoped that an increase in education or energy literacy related to formal and non-formal education so that people are more familiar with and apply energy conservation in their daily lives.

Abstract

Indonesian electricity supply is still dominated by coal-fired power plants (CPP) by more than 50%. Water consumption for CPP in Indonesia reaches 222 million kL/year. Meanwhile, 10% of Indonesia's population is predicted to experience a clean water crisis in 2045. Most of the water consumed by CPP will be disposed of as wastewater, such as cooling tower blowdown and boiler blowdown. Boiler blowdown temperature is still relatively high. Thus, it wastes a high-quality of energy. Therefore, these conditions open the opportunity for innovations in improving clean water supply and increasing CPP’s thermal efficiency. In this research, a novel system that integrates wastewater recovery and waste heat recovery in CPP using reverse osmosis is proposed to produce clean water while increasing the CPP’s thermal efficiency. In this system, the boiler blowdown is streamed to a heat exchanger as the feedwater preheater. Then, the boiler blowdown flows to a Pelton turbine to generate electricity. The boiler blowdown will then be mixed with the cooling tower blowdown and streamed to a reverse osmosis system to produce clean water. The brine is converted by an electrolyzer into NaClO and H2. Thermodynamic and economic analyses are performed to assess the proposed system’s technical and economic feasibility. Based on the thermodynamic analysis calculation using the Engineering Equation Solver, the system is able to produce 162 kL/hr of clean water and the thermal efficiency of the coal-fired power plant increases by 0.4%. The economic analysis showed that the additional system is feasible with a payback period of 4.9 years.

Abstract

In the turn of the twenty-first, China has grown to become the largest energy consumer in the world, the largest energy producer globally and has risen to prominence as one of the leaders in the development of alternative and renewable energy sources. This has granted China the status as a leader in global energy governance. But while China has actively participated in international energy markets as a massive competition, this has also been juxtaposed with an odd reluctance to ambitiously participate in global energy regimes. However, under President Xi Jinping this has changed, and China has become more and more dominant in the global energy sector; not just in the market but now in its governance. From its inclusion in international energy institutions to its role in energy development in the Belt and Road Initiative, BRICS and New Development Bank; we can now see how China has expanded its dominance in the energy sector. By using qualitative methods, this paper critically analyses China’s strive to become a global hegemony via dominance in the energy development sector, both as a tool for its energy security as well as to hold geopolitical control over developing nations that rely on China for their energy needs.
