Rapid insights when you need them

Orbital Stack, a new simulation software platform built by RWDI Ventures, puts the power of advanced climate analysis in your hands.

Generate outstanding results—earlier

Time matters. So does quality. Yet, microclimate analysis that’s too narrow in scope and too late in the design cycle continues to be a common—and costly—source of project compromise and delay. So, how can you ensure the best outcome for your building’s surroundings and occupants?

Nothing out there was good enough, so we built our own

Computational fluid dynamics simulation tools (CFD) shouldn’t leave you with more questions than answers. After trying every option available, RWDI’s world-class engineers and software developers determined that none could sufficiently assess our clients’ complex designs. Orbital Stack’s in-depth insights and self-serve capabilities gives you instant holistic feedback, but you still have access to RWDI’s microclimate specialists when you need them.

Climate-responsive building design

Climate-responsive building design means evaluating factors that impact the usability of surrounding outdoor spaces. And the most optimal designs will extend the usability of these spaces through every season, even into the winter.

Thermal Comfort

Thermal Comfort provides the high-level view of how amenity spaces meet their desired usage profiles, in terms of overall climate comfort throughout the year. By identifying areas and times where conditions are not appropriate, we can dig into the root causes and test possible mitigations.

Pedestrian Wind Comfort

Whether it’s a warming breeze or disruptive gale, wind is one of the biggest contributing factors to outdoor comfort. A CFD simulation of wind conditions, merged with historical climate data, can generate a great statistical view of typical conditions—annually, by season or by time of day. By evaluating specific directional behavior, including streamlines that illustrate flow patterns in areas of concern, you gain deeper insights into areas of concern and how to mitigate them.

Solar Comfort

Sun and shade dictate the comfort, usability and desirability of outdoor spaces. A simple analysis of solar energy—by both season and time of day—will highlight any concerns around thermal comfort, while providing critical insights into what mitigations would be most effective.
