Building Data Exchange: Advancing Standardized BEM Output Reporting
NeuMod Labs, Big Ladder Software, and Zero Envy collaborated on this building data exchange project titled “Advancing Standardized BEM Output Reporting”. The purpose of this project was to develop a standardized data model specification for building energy modeling output reporting along with modern, automatically generated human-readable reports that demonstrate how the schema can support consistent reporting.
This webinar will discuss the development process and demonstrate the schema to generate standardized BEM output reports from three different BEM software.
Speakers
Sagar Rao
Sagar Rao is a recognized leader in the field of computational analysis of the built environment, with cross-disciplinary expertise spanning building physics, data engineering, software development, and artificial intelligence. His work centers on the development of intelligent automation and analytics frameworks for design optimization, enhance building performance, and regulatory compliance.
Sagar serves in technical leadership roles across multiple committees within ASHRAE, IBPSA-USA, and the Illuminating Engineering Society (IES), where he contributes to the evolution of simulation and data standards, automation protocols, artificial intelligence, and data-centric compliance methods. His work consistently bridges computational rigor with practical implementation, positioning him as a key driver of innovation at the intersection of building science, data engineering, and artificial intelligence.
Neal Kruis
Neal Kruis has been developing building energy modeling software since 2007. He is the Vice President of Big Ladder Software and has been contracted as RESNET®’s Energy Modeling Director since 2018. He has a PhD in Architectural Engineering from the University of Colorado at Boulder. Neal is a core developer of the Department of Energy’s EnergyPlus simulation engine and the California Simulation Engine (CSE) used for residential Title 24 compliance calculations. He is an active member of ASHRAE Technical and Standards committees (TC 4.7 “Energy Calculations”, SPC 140 “Method of test for Evaluating Building Performance Simulation Software “, SSPC 205 “Representation of Performance Data for HVAC&R and Other Facility Equipment”, SPC 229 “Protocols for Evaluating Ruleset Implementation in Building Performance Modeling Software”). Neal is also the President of the board for the U.S. affiliation of the International Building Performance Simulation Association (IBPSA-USA).
Greg Collins
Greg Collins, PE, BEMP, LEED AP BD+C, is the founder and principal of Zero Envy, a building energy modeling (BEM) and software firm he started in 2016. Greg has modeled projects across codes, green building rating systems, and utility incentive programs, using a range of simulation engines. That work drives his focus on making BEM results easier to produce, check, and use. Zero Envy’s automation work has grown from Python scripts and plug-ins into full software development. Greg directs development of BEM ToolBox, a web platform for modern, automated BEM reporting built on the IESVE Python API and CBECC. He has also led software development projects for CalBEM / Southern California Edison and the USGBC, and completed the BDE Roadmap project that preceded this output reporting work.
