Recognizing the importance of sustainability in both its design and practices, KlingStubbins takes an integrated approach to its operations and design processes. Beginning in the 1980s, The Challenge ”The biggest challenge we are seeing KlingStubbins merged its architecture As energy and performance have now is that our clients want very detailed and engineering offices to provide become more and more important to information about building performance its clients with a one-stop-shop for successful design projects, KlingStubbins earlier and earlier in the design effort,” has been looking for tools that could help says Jonathan Weiss, Director of exceptional design, and is always coordinate between architectural design Sustainability at KlingStubbins. researching new methods to options and the engineering ramifications “We need to have tools that allow us to streamline the entire design process of these options. Conventional practice make comparative decisions early on, from start to finish. Such integration was to have separate tools used by so that we can make sure that we meet requires leaders from each of the different disciplines, and they were performance targets for energy and looking for a system that could make the company’s core disciplines, including LEED.” While a detailed energy simulation design process as seamless as possible. architecture, engineering and interior, using DOE-2 or Energy Plus would take Finding a way to coordinate between to collaborate when resolving building weeks to build, they needed to find tools 3D modeling tools such as Bentley’s performance issues such as the that could get them moving in the right Generative Components, and Autodesk’s direction earlier in the process, since interrelationship between building Revit was important to KlingStubbins. decisions about form, envelope, and siting, exterior envelope, system Ideally, the application or tool could be primary system decisions can have design and energy and resource used from the earliest design stage an enormous impact on final energy consumption. through to completion. performance. KlingStubbins has worked with several applications but found them either too simple, so the results were not verifiable, or too complex, so the models could not react to quickly changing design decisions. www.iesve.com CaSe STUDy IES PERFORMANCE ANALYSIS INTEGRATION November 2008 | USA “The IES team has been extremely responsive and knowledgeable.
