Quantifying Thermal Resilience with Energy Efficiency in Residential Building Stock Models
With the increasing frequency and intensity of extreme weather events due to climate change, thermal resilience of homes is of increasing importance. The National Renewable Energy Laboratory (NREL) has developed and validated a comprehensive set of energy models to represent the US residential building stock. While NREL has used these to test residential retrofitting packages for energy efficiency, the authors have found no studies testing them for thermal resiliency. Therefore, this study evaluates these proposed retrofits for thermal resiliency during future, extreme weather, and power outage conditions. To achieve this, the authors developed a framework called THERO (THErmal Resiliency evaluation using OpenStudio-HPXML), built on NREL’s foundation, that runs batch simulations for indoor thermal comfort metrics. Simulations were performed on a sample of the energy models in Chicago (n = 500) and Phoenix (n = 200) for future, extreme, and power outage conditions on a baseline case, an upgrade with enhanced enclosure, and an upgrade with high-efficiency whole-building electrification. The indoor thermal resiliency was evaluated across Energy Use Intensity (kWh/m2), Time Not Comfortable (hrs), and Heat Index Hours (hrs). We show that for indoor thermal resiliency, an enhanced enclosure upgrade performs better in Phoenix while a whole building electrification upgrade performs better in Chicago. However, in the case of a power outage, in both cities, an enhanced enclosure upgrade performs significantly better than the electrification upgrade. This study establishes a framework for testing thermal resilience and demonstrates that the goals of indoor thermal resiliency and energy efficiency do not always lead to similar recommendations for residential retrofitting.
