An Analysis of the Hybrid Internal Mass Modeling Approach in EnergyPlus

Author(s)
Zhelun Chen, Jin Wen, Steven T. Bushby, L James Lo, Zheng O'Neill, Vance (Wm.) Payne, Amanda Pertzborn, Caleb Calfa, Yangyang Fu, Gabriel Grajewski, Yicheng Li, Zhiyao Yang
Accurate simulation of building system dynamics is particularly important for understanding building energy flexibility. Among all dynamics in a building, a

ASHRAE's New Position Document on Indoor Carbon Dioxide

Author(s)
Andrew K. Persily, William Bahnfleth, Howard Kipen, Josephine Lau, Corinne Mandin, Chandra Sekhar, Pawel Wargocki, Lan Chi Nguyen Weekes
Indoor CO2 concentrations are often discussed in the context of ventilation and IAQ, most recently in relation to airborne infectious disease transmission

Indoor Carbon Dioxide Metric Analysis Tool

Author(s)
Andrew K. Persily, Brian Polidoro
Indoor carbon dioxide has been used for decades to evaluate indoor air quality (IAQ) and ventilation. However, many applications of CO2 as an indicator or

Using CO2 as a Ventilation Clue in Classrooms

Author(s)
Dustin Poppendieck
In the era of COVID19, we need to quickly find and fix classrooms that have inadequate ventilation to reduce long-range airborne transmission of diseases

A New Spin on Kibble: A Self Calibrating Torque Realization Device at NIST

Author(s)
Zane Comden, Stephan Schlamminger, Charles Waduwarage Perera, Frank Seifert, David B. Newell, Jay H. Hendricks, Barbara L. Goldstein, Leon Chao
After the 2019 redefinition of the International System of Units (SI), torque no longer needs to be traceable to a calibrated weight suspended from a known

A Simple Two-Step Reaction Scheme for Soot and CO

Author(s)
Kevin B. McGrattan, Randall J. McDermott, Jason E. Floyd
A relatively simple two-step combustion model is proposed for predicting soot and CO generation in under-ventilated fire simulations. The scheme consists of two

Electro-Optically Derived Arbitrary Millimeter-Wave Sources with 100 GHz of Bandwidth

Bryan Bosworth, Nick Jungwirth, Kassiopeia Smith, Jerome Cheron, Franklyn Quinlan, Madison Woodson, Jesse Morgan, Andreas Beling, Ari Feldman, Dylan Williams, Nate Orloff, Chris Long
We demonstrate fine phase and amplitude control of millimeter waves, measured on-wafer using an electro-optic frequency comb, programmable spectral filter, and

Multi-User MIMO Enabled Virtual Reality in IEEE 802.11ay WLAN

Author(s)
Jiayi Zhang, Steve Blandino, Neeraj Varshney, Jian Wang, Camillo Gentile, Nada T. Golmie
Virtual reality (VR) coupled with 360° video has been used in a variety of areas, including gaming, remote learning, and healthcare, among others. The 360°
