Our Climate Analysis Options

Powerful multi-factor analysis

As cities emphasize sustainability and citizens push for functional outdoor spaces, the demand for climate-informed architecture is increasing.

At the same time, facility owners recognize the economic benefits of properties that:

  • Attract more foot traffic to ground-level businesses
  • Extend the seasonal availability of outdoor spaces and amenities
  • Preserve user comfort and safety in a range of weather conditions

As a result, designs guided by microclimate and wind loading analysis-especially when used from day one-will have real advantages over those that only examine these effects in project’s later stages.

Gaining crucial insights on every project has never been so easy

Orbital Stack includes all the features you need to gain crucial insights into the outdoor comfort of all of your building designs.

Plus, to help you quickly and affordably take your designs to the next level, Orbital Stack customers can gain additional validation, direction—and confidence—with design guidance and interpretation from RWDI’s building performance, climate engineering, and environmental engineering experts.

Browser based interface

A clientless UI serves as the interface between the building designer and the Orbital Stack cloud, simplifying integration into existing workflows, and avoids the need for software installation and maintenance. A single model can be used to run a range of simulations, providing everything needed to gain valuable insights.

Wind comfort analysis

Presents a statistical view of typical conditions annually, by season, or by time of day, and indicates if a specific location is suited for sitting, strolling, or is uncomfortable and requires mitigation. Learn more

Thermal comfort analysis

Gives you objective metrics (e.g., SPMV*, UTCI) that show you how outdoor spaces meet their desired usage profiles, in terms of overall outdoor comfort for a given season (range of months), time of day period (range of hours), clothing, and activity level. Learn more

Airflow analysis

Examines a location’s average wind speeds from a given direction, illustrating them with arrows and streamlines, and ultimately revealing potential issues with usability, comfort, and safety. Learn more

Daylighting analysis

Presents a statistical view of the solar potential around the site, showing which areas are shaded during the given season (month range) and time of day (hour range), if the sky was clear every day of the year. Learn more

Cladding analysis

Estimates pressures on the entire façade of your building, returning not only peak pressure estimates (min and max) but also directional pressure coefficients (min, max, mean, rms), all through easy to understand graphics that help you make informed cladding design decisions. Learn more

Experts ready to help

Although Orbital Stack is a self-serve platform that puts the power of analysis in your hands, users can still access RWDI’s world-renowned wind and microclimate experts for an additional hourly charge. Whether to gain a better understanding of results or to refine options, RWDI experts are here to help.
