Frequently asked questions.

Dynamic thermal simulation models a building's energy performance hour-by-hour across a full year, accounting for weather, occupancy, HVAC systems, and envelope behaviour. Unlike steady-state calculations, it captures the real interplay between all variables.

We primarily use DesignBuilder and EnergyPlus for energy and thermal modelling, and FDS (Fire Dynamics Simulator) with PyroSim for fire and smoke CFD. All tools are industry-standard and accepted by certification bodies.

The earlier the better. Ideally at concept or schematic design, when simulation can inform decisions about orientation, envelope, and systems — before changes become expensive. We also support later stages for compliance and certification.

An energy simulation for a medium-sized building typically takes 2–4 weeks. Fire CFD can range from 1–6 weeks depending on complexity. Certification consultancy runs alongside the project timeline, from pre-assessment to final submission.

Yes. While based in Bucharest, we work with clients across Europe and beyond. Simulation is software-based, so geography is rarely a constraint. We adapt to local climate data, codes, and certification schemes.

Depending on the service: detailed simulation reports with performance maps, energy balance breakdowns, thermal comfort analyses, fire safety engineering reports with time-resolved visualisations, and complete certification documentation packages.

We are experienced with BREEAM, LEED, WELL, and NZEB compliance. We handle the technical credits — energy modelling, daylight, thermal comfort, indoor air quality — and coordinate with assessors.

Our models are validated against measured data wherever possible. EnergyPlus is DOE-validated and ASHRAE 140-compliant. FDS is NIST-developed with extensive verification. We follow best-practice modelling protocols to minimise uncertainty.
