Nicholas Long works on advancing research in NREL’s Commercial Buildings Research Group’s Controls and Advanced Analytics section. He is a technical lead on various projects related to software development, building data management, and building energy analysis. He has contributed at various levels to several projects, including the Standard Energy Efficient Data (SEED) Platform™, BuildingSync^®, URBANopt, Building Component Library, OpenStudio^® Analysis Platform, OpenStudio, and Building Agent.

Long has experience contributing to projects at an architectural level, as well as programming web- and client-based applications. Long is an expert in software development, large-scale data analysis, and data management. He is also an expert in building energy modeling with OpenStudio/EnergyPlus™ with experience in creating reduced order models from simulated data to decrease simulation runtimes for analyses of novel bi-directional district heating and cooling systems.

Long has participated in discussions and given presentations around the world on building energy efficiency and building energy modeling. He has been cited in over 1,000 publications, is a contributing member of ASHRAE, and is an active member of the International Building Performance Simulation Association.
