Sensitivity analysis can help a designer focus on the most important elements of a design, tell an energy modeler or asset rater what characteristics of an existing building are really significant, help an archtiect ensure the performance of the building is maintained during VE or contractor negoatiations, or expose the best opportunities and lowest risks of an energy retrofit project.
Session 30: New Features for Design Guidance with Automatic Sensitivity Analysis in GBS <-- click here to see Vasari Talk 30, where we introduce sensitivity analysis with the new Potential Energy Savings app from Green Building Studio.
This kind of valuable information is usually obtained by comparing the results of dozens of energy simulations, each varying one or more building parameters. Unfortunately this has always been a tedious and time-consuming process of iteration, process and review, iteration, process and review, and most don't have the time to take advantage of it often enough, even if they do have the technical expertise.
Recently the Green Buidling Studio team introduced for Revit, Vasari and GBS a number of significant improvements to its services that remove the tedium and provide a seamless workflow that includes automatic sensitivity analysis for every simulation job submitted to GBS. Now every BIM user can use the regulated systems in GBS to automatically configure, simulate and visualize the results of 40 design variations in a single step, with appropriate settings for almost any combination of building type, size and location.
Keep an eye out for the second part to be presented in the Vasari Talk session on June 26,
Part 2 - Sensitivity workflows in Revit and Vasari using the new Potential Energy Savings chart
where we will present a project that used the PES extensively, and discuss a number of other ways to use this tool in new and existing building workflows from design to calibration to retrofit to rating.
