Orbital Stack Micro Climate Analysis

Whether in hot climates or temperate ones, small cities or large urban centres, the demand for comfortable outdoor spaces is becoming increasingly apparent. The last two years have forced more social activity into the outdoors. Developers are seeing the importance of outdoor spaces in driving foot traffic that ultimately leads to successful developments. City planners, in places like San Francisco, Toronto, Hong Kong, and London, are demanding attention to outdoor comfort and safety in their planning and approval processes. However, getting the designs right can be a complex balancing act between conflicting objectives, and knowing how a design will behave in the local climate can be equally hard to predict.

For many years, it has been possible to answer these questions, but it has meant long running and expensive CFD simulations that require expert teams to operate and interpret. This has meant that these evaluations have been accessible to only the largest and well funded projects. Analysis was delayed until late in the design process when change was both more difficult and expensive.

In this workshop, we are going to get hands on with rapid, early-stage tools for microclimate evaluation, including AI wind evaluation that gives results in minutes. The workshop will culminate with a final CFD simulation that includes landscaping and porous mitigations.

Your workshop host will introduce the theory behind wind comfort and thermal comfort analysis and discuss the details of some of the different metrics that are used in the field.

This will be followed by hands on work using Orbital Stack to explore the performance of real-world projects.

Participants are expected to bring one or two projects that they can work with during the workshop, evaluating microclimate conditions around the project and optioneering various solutions to any problems that are identified. Workshop facilitator, Goncalo Pedro, will be available to help evaluate and interpret results, and provide guidance and suggestions about massing and mitigation changes to try.
