Vehicle‑to‑building (V2B) systems can harness the energy flexibility of electric vehicles (EVs). This study evaluates the energy flexibility of V2B in office complexes that share their charging infrastructure with nearby residential users during off-hours. First, EVs’ arrival and departure times, state-of-charge (SOC) upon arrival, and required SOC at departure are simulated based on probability distributions

Quasi-experimental evidence that the urban tree canopy reduces residential energy consumption Energy Build. (IF 6.6) Pub Date : 2025-06-09 Fatima Ravazdezh, Nicholas Rivers
The relationship between the urban tree canopy (UTC) and residential space-conditioning electricity use has been explored over the past decades, but depending on the methods and assumptions, there is a wide disparity in the estimated energy savings. Using a quasi-experimental research design, we combine aerial imagery of the UTC with high-frequency electricity consumption data for 1,968 houses in Ottawa
