Buildings incorporating thermal flywheels for seasonal energy storage present unique challenges for Energy Performance Certificate (EPC) modelling. Thermal flywheels store excess heat or coolness during one season and release it later, which can significantly impact predicted energy consumption if not modelled accurately.
Key Considerations for EPC Modelling with Thermal Flywheels:
Dynamic Thermal Storage Assessment – Accurately modelling the energy storage and release cycles of thermal flywheels is critical to prevent overestimation or underestimation of heating and cooling demands. About EPC Rate
Impact on Heating and Cooling Loads – Thermal flywheels alter internal temperature fluctuations, reducing peak heating and cooling loads. EPC software must account for these variations to reflect realistic energy performance. Services – EPC Assessors London
Integration with HVAC Systems – The interaction between thermal flywheels and HVAC systems affects overall energy efficiency. Proper input of system dynamics ensures accurate EPC predictions. Booking an EPC Assessment
Seasonal Performance Simulation – Simulating seasonal storage and release helps assess the building’s year-round energy performance, ensuring EPC ratings reflect true efficiency. Pricing Information
Internal Gains and Occupancy Patterns – Thermal flywheels interact with internal heat gains and occupancy schedules, influencing daily and seasonal energy profiles. Accurate modelling requires detailed occupancy and usage data. Contact EPC Services
Validation and Verification – Post-modelling verification using monitored data ensures EPC predictions align with actual energy performance, particularly for innovative storage solutions like thermal flywheels.
By incorporating these considerations, EPC assessors can produce more accurate and reliable ratings for buildings with integrated thermal flywheels, reflecting their true seasonal energy efficiency and performance.
