Building — Data — Energy

Precision building physics for a net‑zero Brunei.

Optisim Consulting pairs building physics, data, and energy simulation, three disciplines central to Brunei's green building standard.

// 01—03 · What Optisim does

Two services open today, one platform in build, one long-term vision.

From the certification and simulation work we deliver today, through the infrastructure we're building around it, to the national-scale vision it all points toward.

01Service · Open

BAGUS Facilitation

Open for projects

Guiding building owners and developers through the Brunei Accredited Green Unified Seal — from early-design strategy and evidence modelling to documentation and final certification.

  • Design-stage strategy
  • Compliance evidence & modelling
  • Certification submission
02Service · Open

Building Energy Simulation

Open for projects

Dynamic building energy simulation, retrofit analysis, overheating risk, passive design and net-zero pathways — modelled, optimised.

  • Dynamic thermal simulation
  • Retrofit & net-zero analysis
  • Overheating & passive design
03Infrastructure · In dev

BAGUS Infrastructure

In active development

We're building the software backbone for BAGUS — facilitator tooling, compliance tracking, and project workflows that make certification faster, more consistent, and auditable. Currently in active development.

  • Facilitator dashboard
  • Compliance tracking
  • Submission workflow

04 — Long-term vision

A database for every building in Brunei.

The long-term ambition is a nationwide building-stock database, built from BAGUS certification records, that gives Brunei a performance picture of its entire building stock. On that foundation, Local Area Energy Planning could run at national scale, modelled from real building data rather than estimates.

Getting there means building three things in parallel: simulation methods, an accredited certification pathway, and facilitator tooling that captures each project as structured data. Optisim is assembling all three, one certified building at a time.
