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.
The digital backbone for Brunei's green building standard.
Optisim is building the software infrastructure that makes BAGUS certification faster, more consistent, and auditable at scale — from facilitator tooling to a national building-stock database.
In active development
