Seven centrally air-conditioned homes in Kapolei, Hawaii were monitored for one year. Power (kW) use data was collected at a 1-minute resolution using eGauge meters with current transducers inside breaker panels. Data for plug loads and lighting were not disaggregated since they share circuit breakers and are categorized as "other." This is calculated by taking the whole house power use and subtracting all the other end-uses that were measured. Temperature and humidity were measured in three to four locations inside each house and also outdoors, out of direct sunlight, using Onset HOBO U12 loggers and collected at a 15-minute resolution. The neighborhood is located at 21°21°20'19.8"N, 158°03'20.1"W, elevation 23 m. The research paper has been submitted to the "Buildings" journal (open access), titled "Going Beyond Code: Monitoring Disaggregated Energy and Modeling Detached Houses in Hawaii" by W. Meguro, E. Peppard, S. Meder, J. Maskrey, and R. Josephson. This repository holds the data files for sub-metered power of seven houses, indoor temperatures of the houses, outdoor temperatures, and the BEopt file used for the simulations.


Steps to reproduce

See the first tab in Excel workbook file "Kapolei study monitored data tables instructions.xlsx" for instructions. Missing power data is quantified in tab "Missing power data". Estimates for missing data are shown in tabs "Table 4 house 1 with estimate" and "Table 4 house 7 PV estimate". Other spreadsheet data files which are in the "Monitored data" folder (in CSV format) are described in this excel file. We used BEopt The file is uploaded in the "BEopt simulation" folder. The "optimization" tab of BEopt: the "least-energy-optimized" model described in the paper was "optimal #12" in the BEopt output. The "least-cost-optimized" model in the paper was "optimal #8" in the BEopt output. The other tabs in BEopt contain the parametric analysis compared to the IECC2015 minimally compliant model.
