Assessment Challenges for EPC in Buildings with Combined Biofuel and Solar Thermal Systems

Buildings that integrate biofuel-based heating with solar thermal systems provide sustainable energy solutions by combining renewable heat sources with conventional systems. However, this hybrid approach introduces unique challenges for Energy Performance Certificate (EPC) assessments due to variable energy contributions, system interactions, and performance uncertainties. 1. Understanding

EPC Challenges in Buildings with Combined Passive Solar and Active Mechanical Systems

Buildings that integrate passive solar design—such as south-facing glazing, thermal mass, and natural ventilation—with active mechanical systems like HVAC and heat pumps provide both energy efficiency and comfort. However, this combination presents unique challenges for Energy Performance Certificate (EPC) assessments. 1. Understanding Combined Passive-Active Systems Definition:

EPC Considerations for Buildings with Multiple Interconnected Courtyards

Buildings with multiple interconnected courtyards offer enhanced natural lighting, ventilation, and aesthetic appeal. However, these open spaces introduce complexities for Energy Performance Certificate (EPC) assessments due to unique airflow patterns, solar gains, and heat loss behaviors. 1.

How EPC Software Handles Intermittent Mechanical Ventilation Failures?

Mechanical ventilation systems are critical for maintaining indoor air quality and regulating building energy use. However, intermittent failures—due to equipment faults, maintenance issues, or control system errors—can significantly affect a building’s energy performance. Accurately modelling these variations is essential for Energy Performance Certificate (EPC) assessments. 1.

Modelling EPC Ratings for Buildings with Partial Underground Structures

Partial underground structures—such as basements, semi-subterranean floors, or partially buried extensions—offer thermal stability and space optimization. However, their unique thermal characteristics present specific challenges for Energy Performance Certificate (EPC) assessments. 1. Understanding Partial Underground Structures Definition: Portions of a building that are below ground level or

EPC Implications of High Reflectivity Roofing Materials on Solar Heat Gain Modelling

High reflectivity roofing materials, often referred to as cool roofs, are designed to reflect more sunlight and absorb less heat than traditional roofing. While they improve building energy efficiency, they also introduce specific challenges for Energy Performance Certificate (EPC) assessments, particularly in modelling solar heat gain.

How EPC Ratings Account for Variable Heat Distribution in Modular Hybrid Construction?

Modular hybrid construction combines prefabricated modules with on-site building components, offering speed, flexibility, and cost savings. However, variable heat distribution between modules and integrated systems can create challenges when calculating Energy Performance Certificate (EPC) ratings. 1.

EPC Scoring for Buildings with Integrated Renewable Microgrids

Buildings that incorporate renewable microgrids—such as solar PV arrays, wind turbines, or small-scale energy storage systems—can generate a portion of their own electricity on-site. While these systems enhance sustainability and reduce operational costs, they also introduce complexities for Energy Performance Certificate (EPC) scoring. 1. Understanding Integrated

The Role of Microclimate Variation Around Building Envelope in EPC Calculations

Microclimate conditions surrounding a building—such as shading, wind patterns, urban heat islands, and local humidity—can significantly impact energy performance. These variations pose challenges when calculating Energy Performance Certificate (EPC) ratings, as standard EPC methodologies often assume uniform external conditions. 1.
