Rapid Energy Modeling, Benchmarking and Analysis for Campuses

The task of modeling, benchmarking and analyzing multiple buildings on a campus has historically been a very costly task. Labor associated with developing an energy model for multiple buildings can cost several thousands of dollars and require a tremendous amount of data. As more institutions commit to ambitious energy saving targets (such as the 20/20 Challenge, Better Buildings Challenge, President’s Climate Action Plan, or Carbon Neutrality) it can be a daunting task for facility engineers to figure out where to start. Recent research and newly developed tools by industry partners have created an opportunity for campuses to model, benchmark and analyze their buildings in an accurate and quick fashion.

By using the Rapid Energy Modeling tool with Insight 360 from Autodesk, a building energy model can be developed in a matter of minutes. Using this model, the building can be benchmarked to its peers through readily available data from the Commercial Buildings Energy Consumption Survey (CBECS); and newly published data from an ASHRAE research project (RP-1651). These two sources of information allow any building to be benchmarked against CBECS (creating an Energy Star rating), as well as a similar ASHRAE 90.1-2016 compliant buildings and an ASHRAE defined maximum technically efficient building. With that data, a campus can also use the Campus Carbon Calculator from the University of New Hampshire to identify Scope 1 and Scope 2 carbon emissions.

This presentation will showcase how the above tools were used to complete a full-scale Energy Master Plan at two higher education campuses; one in California with over 100 buildings and another in Kentucky with just under 50 buildings. The result was an energy model for every building on campus, roadmaps identifying the highest energy consuming buildings, potential energy savings for every building and a campus carbon footprint. A process that would have normally taken several months was completed within two weeks, and at a fraction of the initial cost.



Since joining 8760 in 2011, Ryan has specialized in the analysis and retrofit of existing facilities with an emphasis on Energy Infrastructure. Ryan has worked with clients to increase system reliability on higher education, healthcare, industrial, local and municipal campuses. As a partner, Ryan has developed 8760 Engineering’s services as the lead principal for Retro-Commissioning, Commissioning, Continuous Commissioning, Automatic Fault Detection and Energy Benchmarking.

In 2004, Ryan began working in the construction industry where he was employed as a summer help for the Local 562 Plumbers and Pipefitters Union. He has since graduated with a degree in Mechanical Engineering from the University of Missouri-Columbia, and a in the Masters of Business Administration at Washington University in St. Louis.

He now sits on the board of directors for the Missouri Energy Initiative, is the past president of the St. Louis Chapter of the Association of Energy Engineers, was a technical advisor to the ASHRAE GPC 36 committee, is a preliminary judge for Arch Grants and founded the non-profit agency Strange Cares.

Ryan is a licensed professional engineer in the state of Missouri, a certified commissioning authority (CxA) and certified energy manager (CEM).
