Precision building physics and energy planning for a net‑zero Brunei.

We help Brunei's buildings perform better: simulation-led design, certification under BAGUS (the Brunei Accredited Green Unified Seal), and the software to scale both.

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

From the certification and simulation work we offer today, through the platforms 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 BAGUS certification, from early-design strategy and evidence modelling to documentation and final submission.

  • 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 and optimised.

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

BAGUS Workspace

In active development

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

  • Facilitator dashboard
  • Compliance tracking
  • Submission workflow
04Platform · In dev

Tenaga Atlas

In active development

Rooftop PV potential for every mapped building in Brunei, aggregated by kampong and mapped against distribution network headroom, to show where solar can connect today and where the network must be reinforced first.

  • Building-level PV potential
  • Network headroom by kampong
  • Rooftop PV scenarios

05 · Long-term vision

From one building to the national building stock.

Simulation today happens one building at a time. The ambition is the scale above it: the national building stock.

Every BAGUS certification leaves behind a structured record of how a building was designed and how it performs. Across enough projects, these records become a national building database, so Brunei's energy planning can use certified data instead of national averages and estimates.

Let's talk about your path to BAGUS.

Most of a building's performance is decided at design stage. Planning a BAGUS submission or a retrofit? Talk to us before the design is fixed. Interested in helping shape BAGUS Workspace or Tenaga Atlas? Reach out.
