Unlock Sustainable Design with Advanced Environmental Simulations
At SIMSTREAM, we specialise in delivering a comprehensive suite of cutting-edge environmental simulation services tailored to elevate the comfort, wellbeing, and energy performance of your building project. Whether you're designing a residential development, commercial space, or public infrastructure, our simulations provide the data-driven insights needed to create environments that are not only efficient but deeply human-centered.
Advanced thermal comfort and air quality simulation to ASHRAE 55, CIBSE TM52, and TM59 standards — ensuring your spaces support the wellbeing and productivity of the people who use them.
Climate-based hourly daylight analysis to assess sunlight access, glare, and light quality — giving design teams the insight to reduce artificial lighting loads and meet wellbeing standards.
Dynamic thermal modelling of building fabric, systems, and operational scenarios. Using CIBSE TM54 or NABERS methodologies to deliver clear strategies to cut energy use and meet net-zero targets.
End-to-end compliance support across Part L, BREEAM, LEED, WELL, and Passivhaus — translating complex regulatory requirements into practical solutions that protect design intent.
