Community dual-carbon · near-zero-carbon governance

Help communities measure carbonclearly, manage finely, plan paths, engage residents, evaluate outcomes

A community-level dual-carbon platform for governments (ecology, housing, urban management), sub-districts, property managers and operators. For both retrofits and new communities, built on proven MeetCarbon Cloud capabilities for accounting, energy control, resident carbon-benefit programmes and near-zero-carbon evaluation.

Six community dual-carbon pain points

Targets have reached grassroots communities that lack tools, data and incentives

01

Emissions cannot be counted clearly

No shared boundary or ledger. Building energy, transport, street lighting, waste and sinks sit in silos, so per-capita and per-area intensity never forms.

02

Energy cannot be seen

Common-area lighting, lifts, pumps and charging lack submetering and live monitoring, so leaks and anomalies are found late.

03

No path to cut carbon

No target breakdown or peaking-path simulation. Retrofit measures lack estimated reductions and priority ranking.

04

Residents do not take part

Green behaviour is unquantified and unrewarded, so awareness does not land and recycling-points participation stays low.

05

Outcomes are hard to evaluate

Cannot benchmark the national near-zero-carbon indicator set, no self-evaluation report, nothing to disclose to superiors or residents.

06

Build cost is high

Stock communities have tight retrofit budgets. Delivery must stay light and reuse existing smart-community assets.

Five capability domains

From the carbon ledger to green energy assets across the community dual-carbon life cycle

B1-B3

Carbon ledger

Full-scope monitoring, accounting, evidence and annual ledgers for building energy, transport, street lighting, waste and sinks.

B4

Smart energy control

Electricity, water, gas, cooling and heat submetering, live common-area monitoring, efficiency analysis, anomaly alerts and diagnostics.

B8 / C-end

Resident carbon-benefit programmes

Personal carbon accounts, reduction scenarios, points rules, mall and benefit redemption to activate everyday low-carbon behaviour.

B9

Near-zero-carbon evaluation

Core and general indicators, pass-rate tracking, self-evaluation reports, inspection tasks and public disclosure.

B5-B7

Green energy and low-carbon assets

Community-scale access and operations for distributed PV, storage, charging, smart lighting, eco-roofs and smart recycling stations.

Five closed business loops

From boundary setup to inspection disclosure — policy-driven data governance

01

Community accounting and inspection

Enter or ingest activity data by boundary → auto-account with emission factors → annual ledger and self-evaluation → benchmark near-zero-carbon indicators → disclose to superiors and residents.

02

Common-area energy monitoring and saving

Connect submeters → live lighting, lift, pump and charging loads → anomaly alerts to work orders → diagnostics and measure tracking.

03

Resident reduction and incentive loop

Residents authorise scenarios → reductions convert to points by methodology → mall redemption → community reduction assets accumulate.

04

Targets and reduction pathways

Set peaking / cut targets → split across energy, buildings, transport and waste → measure library estimates reductions → scenario simulation and peaking path.

05

District supervision and assessment

Compare, rank, warn and assess multiple communities on emissions, pass rates and carbon-benefit participation.

Architecture

Four-layer architecture

Aligned with digital technology for green low-carbon communities and the overall digital carbon-management framework

Sensing

Microgrid and PV-storage-charging agent

Source-grid-load-storage

For community PV-storage-charging and source-grid-load-storage, dispatch against both carbon and bill metrics.

  • 15-minute to daily rolling forecasts for charge/discharge and demand management, keeping outage reserve and TOU spread
  • Under load growth and quota constraints, rank storage / PV expansion and investment bands, and show the pass-through to purchase cost and green-power share

Atan

Community dual-carbon conversation assistant: ask trends, look up policy, dispatch work orders in one sentence.

How is this month’s community carbon trend?
Net emissions fell 4.2% month on month, mainly from common-area lighting retrofit. Next month’s per-capita emissions are forecast at about 0.61 tCO₂, inside the pass band.
What does Hong Kong carbon-neutral community planning require of existing communities?
Under the Hong Kong Climate Action Plan 2050 energy-saving and green-building strategy, existing commercial buildings need 30–40% less electricity versus 2015. BEAM Plus existing-building retrofit notes are attached.
Create an efficiency-retrofit work order for Building 3
Work order #0421 created: Building 3 chiller VFD retrofit, about 18 tCO₂/year. Submitted to property for approval.

AI assists decisions and speed. Accounting issuance, inspection reports and work-order execution keep human review and approval, with auditable traces on key actions. Domestic / Hong Kong / international languages and standard framings are supported.

The Huansha Lake EOD uses a four-layer sensing–transport–platform–application stack and a district carbon-management platform covering collection, live monitoring, energy statistics, smart energy management, fault diagnosis and intelligent monitoring. This system’s accounting, energy control, low-carbon assets, carbon-benefit, map and dashboards map to the project’s three workstreams: public-building efficiency, district low-carbon scenes, and the carbon platform. Resident carbon-benefit can link with local programmes such as Wu Carbon Jianghu / Wu Carbon Tong, closing the behaviour–points–incentive loop.
