Jakarta's building efficiency rules meet a new wave of smart energy management

What happened

On July 28, 2026, Schneider Electric Indonesia used a media masterclass at its Jakarta headquarters to make a public case that has quietly been building in Indonesian regulation for three years: buildings are one of the largest and most fixable sources of wasted energy in the country's cities. The event, themed "Smart Technology for Efficient Buildings," set out four pillars for what the company calls the buildings of the future: hyper efficient, resilient, sustainable, and people centric. Reza Syarif, the company's Business Vice President for Buildings, framed the pitch in plain terms.

"Efficiency is not just reducing electricity consumption, but ensuring energy is used appropriately without sacrificing reliability, safety and user comfort," Reza said.

The timing is not incidental. The campaign lands on top of a regulatory stack that has been assembling since 2023: the Ministry of Public Works' Regulation No. 10/2023 on smart buildings, the Ministry of Energy and Mineral Resources' Regulation No. 8/2025 on energy management, and, most directly, Jakarta Governor Regulation (Pergub) No. 5/2026 on energy and water efficiency in buildings, issued in February this year. Together they give Indonesia's largest city, and by extension other municipalities watching its lead, a legal and technical basis to demand better performance from the buildings its residents spend most of their lives inside.

Why buildings keep wasting energy

The scale of the problem is well documented but persistently under-addressed. Citing data from Architecture 2030, the companies and outlets covering the campaign noted that buildings account for nearly 40 percent of global carbon emissions. In Jakarta specifically, the building sector is estimated to be responsible for around 60 percent of the capital's total emissions, according to figures cited by DPRD DKI Jakarta during deliberation of the efficiency regulation. Citing the US Environmental Protection Agency, the same coverage put the share of building energy lost to suboptimal management at roughly 30 percent.

Part of the reason is structural rather than behavioral. Around 95.5 percent of the operational data collected across the construction and engineering industries reportedly goes unused for efficiency improvements, and close to 40 percent of a building's operational inefficiencies are effectively locked in during the design phase, before a single tenant moves in. That combination, plentiful data with almost no feedback loop into operations, is precisely the gap that digital building management systems are built to close. Schneider Electric's own modeling suggests that phased adoption of such systems, layering monitoring, automated control, and predictive maintenance over time rather than all at once, can reduce a building's electricity consumption by up to 15 percent, with a target range of 10 to 15 percent in realized monthly savings once systems are fully tuned.

A working case study: SMC RS Telogorejo

Numbers from a vendor's own launch event deserve scrutiny, so the more useful data point is what has already happened at a real site. SMC Rumah Sakit Telogorejo, a hospital in Semarang, adopted an integrated Building Management System, Schneider Electric's EcoStruxure Building Operation platform, to bring HVAC, electrical systems, lighting, security, and power monitoring into a single control center. According to facility manager Rio Oktavianus, the hospital's annual electricity costs had been climbing by roughly 9 percent a year before the system went in. In 2025, the first full year of operation under the BMS, that trend reversed: total electricity spending fell by 5 percent compared with 2024.

The efficiency gains were not confined to the electricity bill. Response time to technical anomalies, a critical metric in a hospital where HVAC and power failures carry direct patient-safety consequences, improved by 60 percent thanks to automated alerts replacing manual rounds. The hospital also reported maintaining its required temperature and humidity standards in operating rooms at a 100 percent compliance rate under the new monitoring regime, addressing the "without sacrificing reliability, safety and user comfort" condition that Reza Syarif set out in his framing of what efficiency should mean. For a public institution audience, the hospital case is instructive precisely because it is not a showcase office tower: it is a facility with the safety margins, budget constraints, and around-the-clock operating requirements that resemble government buildings, schools, and public hospitals across the country.

The regulatory push: Jakarta's Pergub 5/2026

Pergub No. 5/2026 replaces a 2012 regulation on energy and water savings that Jakarta officials say had fallen out of step with the city's current targets and technology. Its central technical tool is Energy Consumption Intensity, or IKE, measured in kilowatt hours per square meter per year, which sorts buildings into four bands: very efficient, efficient, adequately efficient, and wasteful. Water use is tracked in parallel, in liters per square meter or per person per day, closing off the loophole of treating energy and water efficiency as separate problems.

The regulation is explicitly tied to emission targets rather than treated as a standalone building code. Jakarta's provincial government has framed it as support for a national greenhouse gas reduction commitment of 31.89 percent, with the city itself pursuing a more ambitious local target of 50 percent by 2030 and net zero emissions by 2050. Wahyu Dewanto, Deputy Chair of Commission B at the Jakarta legislature (DPRD), described the rule as developed in partnership with the Climate Action Implementation program and the C40 Cities network, calling it a genuine step toward reducing energy and water consumption in large cities. Coverage of the regulation has also had to correct a misconception that circulated after it was issued: the rule regulates efficiency, including of groundwater use, but does not amount to an outright ban on groundwater extraction, a distinction several outlets felt necessary to clarify given how the policy was initially reported.

Sirkularium's view

For government and public institution audiences, the value in this week's developments lies less in the marketing event itself than in the alignment it reveals between regulation, verified private-sector performance, and city-level emission accounting. Jakarta's Pergub 5/2026 gives building owners, including public agencies managing their own facilities, a standardized metric in IKE against which to judge performance, rather than relying on anecdote or utility bills alone. The SMC RS Telogorejo case shows that a facility with safety-critical operations can adopt this kind of system without compromising reliability, which should reduce the hesitation that often slows public-sector technology adoption in hospitals, schools, and administrative buildings.

The clearer near-term opportunity is for public institutions to treat building energy management as a financing and procurement question rather than a purely technical one. An intervention that reliably turns a 9 percent annual cost increase into a 5 percent reduction, as recorded at the Semarang hospital, pays for itself within a normal capital planning horizon, and IKE-based classification gives procurement officers a defensible basis for prioritizing which public buildings to retrofit first. What is worth watching next is whether other provinces follow Jakarta's lead in adopting IKE-based building codes, whether the national Ministry of Energy and Mineral Resources moves to standardize the metric across jurisdictions under its 2025 energy management regulation, and whether financing institutions begin to treat verified BMS-driven savings as collateral for green building loans, the kind of instrument that could scale retrofits well beyond what any single vendor campaign can achieve on its own.
