Description:
SPAGHETTI (Synthetic Patterns & Activity Generator for Home-Energy & Tomorrow’s Transportation Investigation) is a tool that can be used for the synthetic generation of realistic EV drive cycles. It takes as input EV user commuting and non-commuting patterns, allowing for personalised modeling of EV usage. It is based on a thorough literature survey on post-Covid work-from-home (WFH) patterns and can also be used to model the EV usage patterns of the three most common types of post-Covid workers. SPAGHETTI can be used by the scientific community to conduct further research on the large-scale adoption of EVs and their integration into domestic microgrids.

SOPEVS: Sizing and Operation of PV-EV-Integrated Modern Homes

Description:
We address a problem that arises at the confluence of three recent trends: the popularity of storage-coupled photovoltaic (PV) systems amongst homeowners, the rapid proliferation of electric vehicles (EVs) with potential for bidirectional energy storage within PV-enabled single-family homes, and third, the surge in remote working accelerated by the Covid-19 pandemic. In this context, we explore the joint optimal sizing and operation of domestic homes while accounting for different degrees of remote working and the impact of home energy management system (HEMS) operation preferences. This task is complex due to the coupling between sizing and operation and the stochastic and non-stationary nature of solar generation, load, and EV drive cycles. We introduce SOPEVS (Sizing & Operation of PV and EV integrated Single-family homes), a novel framework formulated to tackle this multifaceted challenge. We use SOPEVS to investigate how commuting habits and choices in HEMS operation affect the sizing of domestic PV energy systems. Our findings reveal that homeowners who predominantly work from home and possess bidirectional EVs can potentially eliminate the need for separate home storage systems, thereby substantially reducing overall system costs. We also find that configuring a HEMS to maximise charging through solar energy can achieve savings of up to 80% on total system expenditure (excluding the cost of EV), depending on the desired level of grid independence and the preferred State of Charge (SOC) of EV at the time of departure.

Heatalyzer: A Tool for Evaluating Indoor Comfort in Buildings during Extreme Heat Events
Author:
Livia Capol, Master’s student in Computer Science at ETH Zurich and Visiting Student at the Department of Computer Science and Technology at the University of Cambridge
Description:
The increase in heatwaves due to climate change poses significant challenges to both indoor thermal comfort and occupant well-being. Unfortunately, existing work does not quantify the impact of extreme heat events as a function of building type, occupant age, and heatwave intensity and duration. We therefore present Heatalyzer, a novel Building Energy Modeling (BEM) tool to analyze indoor thermal comfort, liveability, and survivability for a range of buildings under both past and future weather scenarios. It lets users compare these outcomes across building types and weather scenarios, integrates algorithms for creating extreme weather data, and has a user-friendly interface. Additionally, it outputs several commonly used thermal comfort metrics, which are crucial for evaluating indoor conditions during heatwaves. These functionalities enable a wide audience, including building managers and policymakers, to assess the impact of extreme heat events on building occupants.
