Concurrent Design Workflow A project supported
by United Technologies Research Center Sub-Task
under NIST ATP Project Integrated Concurrent
Design of High Performance Buildings
Prepared by Y.C Huang Center for Building
Performance and Diagnostics Pittsburgh,

Context of Study - Need for Lighting
Simulations - Different Semantics in Different
Tools - Expert knowledge required for use - Lots
of time required to set up lighting simulation -
Metrics of lighting analyzes - Outdated
simulation engines Methodology - Automated
translation between semantics - Remove the need
for middleware Unified performance modeling -
Assisted preparation for lighting simulations -
Automated LEED standards checking Challenges -
General Parser - Database of typical values -
Cognitive Post-processes - PNP Scalable Engines
