Dome-like observatories and planetarium buildings present unique architectural and energy challenges. Their curved geometry, expansive glass sections, and specialized interior environments require careful analysis for Energy Performance Certificate (EPC) assessments. Standard EPC models assume rectilinear spaces with uniform thermal zones, making dome structures particularly complex to evaluate for energy efficiency.

Key EPC Challenges

1. Complex Thermal Geometry
The curved surfaces of domes create non-uniform heat distribution. Standard EPC models, which assume flat walls and ceilings, may not accurately predict heat gain or loss in dome structures.

2. Extensive Glazing and Solar Gain
Many observatories or planetariums use large glass panels or skylights for natural lighting and observation. These features can increase solar gain, affect internal temperatures, and complicate heating and cooling load calculations.

3. Specialized HVAC Requirements
Dome structures often require precise climate control to maintain equipment and exhibit conditions, such as telescope humidity levels or projection systems. HVAC loads are therefore atypical and must be accurately modeled for EPC ratings.

4. Zonal and Ventilation Complexity
The interior of domes may consist of multiple interconnected zones, such as observation areas, equipment rooms, and public galleries. Airflow patterns in curved spaces differ from standard rooms, affecting ventilation efficiency and energy consumption.

5. Integration with Renewable Systems
Dome structures may incorporate solar panels, passive cooling strategies, or energy-efficient lighting. EPC assessments must consider how these renewable and efficiency measures interact with the unique thermal behavior of the dome.
