Electric Vehicle Integration in Zero-Carbon Buildings: A Study on Carbon Emissions and Economic Performance

Strategic Insights

— 1 min read

A recent study from the Beijing University of Technology has shed light on the feasibility of integrating electric vehicles (EVs) into zero-carbon buildings. The research, funded by the National Key R&D Program of China, proposes a dual-layer optimization approach to balance economic and carbon emissions objectives. The study applied this approach to a typical zero-carbon building in Beijing, China, and found that prioritizing carbon emissions reduction can lead to a 12.47% decrease in carbon emissions, but with modest economic savings of 12.08%. Conversely, optimizing for economic benefits can reduce costs by up to 25.38%, but at the cost of a 17.03% increase in carbon emissions.

Key Takeaways:

  • The study proposes a dual-layer optimization approach combining day-ahead EV scheduling and V2B bidirectional charger configuration to balance economic and carbon emissions objectives in zero-carbon buildings.
  • The approach was applied to a typical zero-carbon building in Beijing, China, and found that optimizing for economic benefits can reduce costs by up to 25.38%, but at the cost of a 17.03% increase in carbon emissions.
  • Prioritizing carbon emissions leads to a reduction of up to 12.47% in carbon emissions, but with modest economic savings of 12.08%.
  • The study reveals that effective peak-valley arbitrage using EVs remains challenging under current electricity prices and battery costs.
  • The research highlights the importance of balancing carbon emissions reduction with cost efficiency when defining optimization objectives in zero-carbon buildings.
  • The study's findings have implications for policymakers, building owners, and operators seeking to reduce carbon emissions while ensuring economic viability.

Statistics:

  • Up to 25.38% reduction in costs achievable by optimizing for economic benefits.
  • Up to 12.47% reduction in carbon emissions achievable by prioritizing carbon emissions.
  • A 17.03% increase in carbon emissions resulting from optimizing for economic benefits.
  • 12.08% economic savings achievable by prioritizing carbon emissions.
  • 12.47% decrease in carbon emissions achievable through dual-layer optimization.
