Services & platform

The method, and what we're building with it.

Two services open for projects today (BAGUS facilitation and building energy simulation), and two platforms in development: BAGUS Workspace, to scale Brunei's green building standard nationwide, and Tenaga Atlas, for rooftop solar and network planning.

Platforms in development

BN

Primary focus · Brunei

// 01 · BAGUS Facilitation

Guiding developers through Brunei's green building seal.

From early-design strategy and evidence modelling to documentation and final certification. Open now for developers, building owners, and institutional teams.

Open for projects
Illustrative compliance evidence tracker showing three facilitation phases (design-stage strategy, compliance evidence and modelling, and certification submission), each with a completion status and checklist
Demonstration · Illustrative

Sample compliance evidence pack

An illustrative walkthrough of the design-stage strategy, evidence modelling, and submission documentation a BAGUS facilitation engagement produces.

// 02 · Building Energy Simulation

Dynamic simulation, retrofit, and net-zero pathways, modelled.

Dynamic thermal simulation, retrofit analysis, overheating risk, and passive design. Open now, standalone or alongside a BAGUS facilitation engagement.

Open for projects

Demonstration · Illustrative

Sample dynamic simulation output

24-hour temperature (°C) profile of a sample detached model, comparing outdoor, corridor (without air conditioning), and bedroom (with air conditioning) temperatures. Results are obtained from EnergyPlus simulations utilising EPW_TMY weather file.

// 03 · BAGUS Workspace

The digital backbone for Brunei's green building standard.

Optisim is building the software infrastructure that makes BAGUS certification consistent, traceable, and scalable: from facilitator tooling to a national building database.

In active development
BAGUS Workspace sign-in screen: one platform for the full BAGUS journey, for facilitators and reviewers
Platform · In Development

Workspace sign-in, early build

One platform for the full BAGUS journey: centralised scoring, evidence upload, reviewer comments, and workflow status for facilitators and reviewers alike.

// 04 · Tenaga Atlas

Where solar can connect, and where the network must grow first.

Rooftop PV potential for every mapped building in Brunei, aggregated by kampong and mapped against distribution network headroom.

In active development
Tenaga Atlas early build: satellite map of a kampong outlined on screen, with a detail panel showing buildings mapped, rooftop capacity, annual generation, network position and uptake scenarios
Platform · In Development

Kampong detail, early build

Every mapped building carries a modelled rooftop PV capacity and annual yield. Aggregated to kampong and mapped against feeder headroom, it shows where solar can connect today. Network figures in this early build are placeholder data.

Facilitation and simulation are open now. And if you're running BAGUS in-house, we want to hear what slows you down — that's the problem BAGUS Workspace is being built to solve. If rooftop solar and network planning is on your agenda, we want your input on Tenaga Atlas too. Either way, reach us at info@optisim.consulting.
