Apartment BER Expertise

Apartments present unique energy assessment challenges that don't arise in standard houses. Shared party walls, varied orientations across a single block, communal heating systems, complex geometries, and the interaction between adjacent units all require specialist knowledge.

We've assessed thousands of apartment units across Dublin and nationwide — from 4-unit infill schemes to 300+ unit purpose-built complexes. We understand the particular Part L challenges of apartment design and know how to model them accurately in DEAP.

Key Apartment Considerations

• Orientation effects: Units on different sides of a block will achieve different BER ratings due to solar gain variations
• Communal heating: Central plant systems require specific modelling approaches in DEAP
• Thermal bridging: Balconies, setbacks, and complex junctions need careful assessment
• Ventilation: MVHR systems in apartments require commissioning data for accurate assessment
• Airtightness: Testing protocol for apartments differs from houses — we handle the specific requirements
