District-Scale Analysis of Electricity Load and Strategies to Improve Energy Reliability Using Prototype District Models
Novel prototype district building energy system models were developed • Prototype district models support district-scale energy analysis and planning • Electricity load growth can significantly raise peak demand, e.g., 43% rise in CZ 5B • Demand flexibility measures reduced peak loads by 8.3%–16.5% • Optimal backup power solutions depend on location, utility rates, and climate zones Projected increases in electricity demand in the U.S. highlight …
Mapping heat vulnerability in cities
An HVI map tool integrating outdoor-indoor heat exposure and building characteristics. • Allow customization of factor weights for tailored HVI applications. • Apply the tool to Fresno and Oakland revealing distinct vulnerability patterns. • Building heat resistance needs consideration for indoor heat risk assessment. • Support decision making on short-term heat mitigation and long-term urban planning. Extreme heat is a major cause of weather-rel…
Anthropogenic heat from buildings in Los Angeles County
Anthropogenic heat (AH), i.e., waste heat from buildings to the ambient environment, increases urban air temperature and contributes to the urban heat island effect, which leads to more air-conditioning energy use and higher associated waste heat during summer, forming a positive feedback loop. This study used a bottom-up simulation approach to develop a dataset of the annual hourly AH profiles for 1.7 million buildings in Los Angeles (LA) County…
Defining weather scenarios for simulation-based assessment of thermal resilience of buildings under current and future climates
In response to increasingly severe weather conditions, optimization of building performance and investment provides an opportunity to consider co-benefits of thermal resilience during energy efficiency retrofits. This work aims to assess thermal resilience of buildings using building performance simulation to evaluate the indoor overheating risk under nine weather scenarios, considering historical (2010s), mid-term future (2050s), and long-term f…
Assessment of energy and thermal resilience performance to inform climate mitigation of multifamily buildings in disadvantaged communities
The compound impacts of heatwaves and power outages pose a serious indoor heat-related health risk for residents living in disadvantaged communities (DACs) with limited or no air conditioning. In this study we selected 13 heat vulnerable multifamily buildings in El Monte, in Los Angeles County, and employed CityBES to evaluate their energy and thermal resilience performance. A retrofit package with seven passive and low-power active measures—cool…
US urban land-use reform
Policy approaches to the global energy transition often focus on technology-based solutions while ignoring challenges of overall energy demand. A sufficiency-first approach aims to limit superfluous consumption while achieving wellbeing for all. This study focuses on US built environment mechanisms of sufficiency under urban land-use policy. The historical context of US exclusionary and car-oriented planning is reviewed with an order-of-magnitude…
Nexus of electrification and energy efficiency retrofit of commercial buildings at the district scale
Evaluating energy retrofits of historic buildings in a university campus using an urban building energy model that considers uncertainties
Prioritize energy sufficiency to decarbonize our buildings
Informing the planning of rotating power outages in heat waves through data analytics of connected smart thermostats for residential buildings
With climate change, heat waves have become more frequent and intense. Rotating power outages happen when the power supply is unable to meet the cooling demand increase resulting from extreme high temperatures. Power outages during heat waves expose residents to high risks of overheating. In this study, we propose a novel data-driven inverse modelling approach to inform decision makers and grid operators on planning rotating power outages. We fir…
