Abstract

Working with the Lab for Ecohydrological Applications and Forecasting (LEAF) in the Department of Geosciences at Boise State University, we were able to determine the energy efficiency of the Yanke Research Park Building. Two different models were reviewed to automate the process of creating change point models for monitoring the energy use over time using the computational tool, Python. The first model, a 2P model, reflected a single linear regression model when fitted against a “cooling shape”, where building energy use is positively correlated to outside air temperature. The second, a 3PC model (3P Cooling model), contains two slopes connected by a temperature change point. A changepoint was determined through iterations of the temperature data. Before the computed change point there is a zero slope and after the change point, a positive slope. This would take in consideration the building having no heating demand in cooler temperatures. We analyzed post-retrofit data provided by Idaho Power that included the hourly electricity use and the outside air temperature (OAT) from December 1, 2015 to December 1, 2016. The results from the OAT and electricity use data indicated that the Yanke building has some performance gaps in the way it utilizes energy.
