The Chemical Assessment of Surfaces and Air (CASA) Study: Using chemical and physical perturbations in a test house to investigate indoor processes

June 21, 2024
Author(s)
Delphine K Farmer, Marina E Vance, Dustin Poppendieck, Jon Abbatt, Michael R Alves, Karen C Dannemiller, Cholaphan Deeleepojananan, Jenna Ditto, Brian P. Dougherty, Olivia R Farinas, Allen H Goldstein, Vicki H Grassian, Han Huynh, Deborah Kim, Jon C King, Jesse Kroll, Jienan Li, Michael Link, Liora Mael, Kathryn Mayer, Andrew B Martin, Glenn Morrison, Rachel O'Brien, Shubhransgshu Pandit, Barbara Turpin, Marc Webb, Jie Yu, Stephen Zimmerman
The Chemical Assessment of Surfaces and Air (CASA) study aimed to understand how chemicals transform in the indoor environment using perturbations (e.g., cooking, cleaning) or additions of indoor and outdoor pollutants in a well-controlled test house

Electrical and Electroluminescence Evaluation of 17 Year Old Monocrystalline Silicon Building Integrated Photovoltaic Modules

December 25, 2023
Author(s)
Andrew Shore, Tali Schlenoff, Bakary Coulibaly, David Navon, Stephanie Moffitt, Brian P. Dougherty, Behrang Hamadani
Longterm reliable operation of photovoltaic modules is necessary to ensure the technology is key to reducing the cost of solar energy. However, degradation mechanisms in the field are not always consistent or predictable. We present a dataset of 72

Empirical Validation of Whole Building Energy Simulation Program under Free-Floating Conditions

Lisa Ng, Kim Hyojin, Elizabeth Scacifero, Park Minkyeong, Im Piljae, Brian P. Dougherty, Vance (Wm.) Payne
This paper presents one of the ongoing validation efforts using a low-load residential house: the Net-Zero Energy Residential Test Facility (NZERTF) located on the campus of NIST in Gaithersburg, MD, USA. Among a set of validation tests performed at NZERTF

Characterization of Long-Term Sub-Hourly Thermal Comfort Performance Data

November 1, 2020
Author(s)
Hyojin Kim, Lisa Ng, Brian P. Dougherty, William V. Payne
Current thermal comfort standards do not provide guidelines on how to graphically characterize and benchmark long-term, sub-hourly, thermal comfort. In an effort to address this void, several statistical characterizations and advanced visualization methods

Technology Development and Field Monitoring in nZEB

July 1, 2020
Author(s)
Vance (Wm.) Payne, Brian P. Dougherty
The International Energy Agency (IEA) Heat Pumping Technologies (HPT) Annex 49, "Design and Integration of Heat Pumps for Nearly Zero Energy Buildings," deals with the application of heat pumps as a core component of the HVAC system for nearly or net-zero

Balancing Energy and IAQ: NIST Net-Zero Energy Residential Test Facility

April 18, 2018
Author(s)
Lisa C. Ng, Dustin G. Poppendieck, William S. Dols, Brian P. Dougherty, Steven J. Emmerich
Buildings used 39 % of all energy used in the United States in 2017, with residential buildings and commercial buildings accounting for 20 % and 19% (EIA 2018) respectively. Zero energy buildings have the potential to help extend and accelerate the recent

Differential degradation patterns of photovoltaic backsheets at the array level

February 4, 2018
Author(s)
Andrew W. Fairbrother, Matthew Boyd, Yadong Lyu, Julien Avenet, Peter Illich, Michael Kempe, Brian P. Dougherty, Laura Bruckman, Xiaohong Gu
Photovoltaic backsheet degradation is commonly related to end-of-life failure of a module, and as such is an important factor in system reliability and longevity. Some module manufacturers have recently begun utilizing non-fluoropolymer-based backsheets in

Small Changes Yield Large Results at NIST's Net-Zero Energy Residential Test Facility
